Introduction

When global manufacturers search for a functional additives supplier in China, the requirement is rarely limited to one individual product.
Modern polymer, coating, film, photovoltaic, battery, semiconductor and fiber applications often require multiple properties to be improved simultaneously—from hydrolysis resistance and weatherability to crosslinking, antimicrobial performance, dispersion and long-term material stability.
Founded in 2010, Shanghai Langyi Functional Materials Co., Ltd. focuses on specialty functional additive solutions and provides functional differentiation services across multiple industrial value chains. The company integrates R&D, manufacturing and sales, supported by operations in Shanghai and Shandong.
While international customers may already know LANGYI for technologies such as infrared blocking agents and ionic adsorbents, Shanghai Langyi’s current product portfolio extends much further.
According to the company’s official product center, its technologies are organized into five major platforms:
- Specialty chemical functional materials
- Water-based curing agent functional materials
- Inorganic micro- and nano-functional materials
- Fine polymer functional materials
- Advanced carbon-silicon-based functional materials
This article introduces the major LANGYI products beyond infrared blocking and ionic adsorption, and explains how these material platforms support advanced industrial applications.

From Functional Additives to Advanced Material Solutions
Shanghai Langyi’s product development is built around solving performance problems in materials rather than simply supplying commodity chemicals.
The company’s official application portfolio covers photovoltaic materials, high-performance resins, functional films, lithium batteries, semiconductor materials, functional fibers and degradable materials.
Different industries may appear unrelated, but many of their material challenges are similar.
Manufacturers frequently need to improve:
- Hydrolysis resistance
- Processing stability
- Molecular weight retention
- Crosslinking performance
- UV durability
- Antimicrobial properties
- Odor control
- Antistatic properties
- Adhesion and dispersion
- Long-term reliability
LANGYI therefore develops different material technologies that can address these requirements from multiple directions.
1. Specialty Chemical Functional Materials
Shanghai Langyi’s official product center currently lists several major specialty chemical functional material categories:
- Anti-hydrolysis agents
- Chain extenders
- UV-resistant materials
- UV-to-visible-light conversion materials
- Infrared high-reflection materials
- Specialty monomer materials for photoresist applications
These products are designed around polymer durability, processing performance and optical functionality.
Anti-Hydrolysis Agents
HyMax® anti-hydrolysis agents represent one of Shanghai Langyi’s established product technologies.
According to the company’s official history, the first HyMax anti-hydrolysis product entered stable mass production in 2012, and the company states that the HyMax series had achieved the leading domestic market share by 2015.
The technology is designed to address hydrolytic degradation in polymer materials.
Shanghai Langyi explains that HyMax anti-hydrolysis agents react with carboxylic acids generated during polymer degradation, forming stable urea-based compounds and helping inhibit further hydrolysis.
The company currently lists several forms of HyMax anti-hydrolysis materials, including:
- Anti-hydrolysis masterbatch
- Liquid-type anti-hydrolysis agent
- Polymeric anti-hydrolysis agent
- Monomeric anti-hydrolysis agent
Applications highlighted by Shanghai Langyi include polymer systems such as PET, PBT, TPU, PU, PC and PA, as well as biodegradable materials including PLA and PBAT.
For manufacturers operating under heat and humidity, hydrolysis resistance can become an important factor in maintaining mechanical performance and service life.
Chain Extenders

Chain extenders are another major product direction within LANGYI’s specialty chemical platform.
Shanghai Langyi describes its reactive HyMax chain extenders as materials capable of reacting with polymer functional groups and extending polymer chains, thereby increasing molecular weight and helping improve or restore overall polymer performance.
This makes chain-extension technology particularly relevant when manufacturers need to address issues such as:
- Polymer degradation during processing
- Reduced molecular weight
- Insufficient melt strength
- Recycled-polymer performance
- Biodegradable-polymer processability
The company specifically identifies applications in both conventional polymers and biodegradable materials such as PLA and PBAT.
For degradable materials, Shanghai Langyi’s application page states that chain extenders can improve PLA/PBAT melt strength, heat resistance, processing behavior and finished-product toughness.
UV and Optical Functional Materials
Shanghai Langyi’s current specialty chemical portfolio also includes:
UV-resistant materials
and
UV-to-visible-light conversion materials.
These technologies expand LANGYI’s optical-material portfolio beyond infrared management.
UV resistance is particularly relevant to materials exposed to prolonged sunlight or outdoor conditions, while wavelength-conversion technology offers another route for modifying how materials interact with incoming light.
The company also lists infrared high-reflection materials within the specialty chemical category.
This is a separate product direction from the infrared blocking agents highlighted on Hong Kong Langyi’s international website and reflects the broader optical-functional-material capabilities of Shanghai Langyi.
Specialty Monomers for Photoresist Applications
Another product category listed by Shanghai Langyi is:
specialty monomer materials for photoresist.
Photoresist chemistry is used in highly controlled imaging processes for electronics and semiconductor-related manufacturing.
The inclusion of specialty photoresist monomers in LANGYI’s product platform demonstrates that the company’s specialty chemical portfolio extends from traditional polymer modification into higher-value electronic material chemistry.
For overseas customers in electronic materials, this also creates opportunities to discuss requirements beyond conventional polymer additives.
2. Water-Based Curing and Crosslinking Materials
Environmental requirements and the transition toward waterborne coatings, adhesives and polymer systems have increased demand for effective water-compatible crosslinking technologies.
Shanghai Langyi’s official water-based curing material portfolio currently includes:
- Carbodiimide curing agents
- Blocked isocyanate curing agents
- Oxazoline curing agents
The company also markets its HyMax® CA environmentally friendly water-based crosslinking agent series.
Carbodiimide Crosslinkers
Carbodiimide chemistry is an important technology platform for Shanghai Langyi.
The company currently promotes HyMax® CA environmentally friendly carbodiimide-based waterborne crosslinkers and positions these products for high-performance crosslinking of water-based material systems.
Typical industrial formulation targets may include improvements in:
- Water resistance
- Chemical resistance
- Adhesion
- Crosslinking
- Durability
For manufacturers moving from solvent-based to water-based technologies, the challenge is not only reducing VOC emissions but maintaining the performance required by the end application.
LANGYI’s water-based curing platform is developed around this type of material-performance requirement.
Blocked Isocyanate Curing Agents
Shanghai Langyi’s product center also lists blocked isocyanate curing agents, and its recent product communication identifies HyMax® WBI as a blocked-isocyanate curing technology.
Blocked systems can provide formulators with another curing option when process temperature, storage stability and crosslinking conditions need to be carefully managed.
Rather than assuming that one crosslinker chemistry is suitable for every formulation, manufacturers should evaluate resin functional groups, curing temperature and final performance requirements when selecting a system.
Oxazoline Curing Agents
Oxazoline curing agents form the third major category in Shanghai Langyi’s official water-based curing portfolio.
Together, carbodiimide, blocked-isocyanate and oxazoline technologies give formulators multiple routes for designing water-based crosslinking systems.
This is particularly valuable in industries where coatings, adhesives or functional films need to combine environmental performance with durability.
3. Antimicrobial, Deodorizing and Antistatic Functional Materials
Within its inorganic micro- and nano-functional material platform, Shanghai Langyi lists:
- Antimicrobial agents
- Deodorizing agents
- Antistatic agents
in addition to infrared blocking and ionic adsorption products.
AntibacMax® Antimicrobial Materials
Shanghai Langyi markets its antimicrobial technology under the AntibacMax® brand.

Shanghai Langyi identifies applications across:
- Rubber
- Plastics
- Films
- Textiles
- Ceramics
- Coatings
The company also states that AntibacMax antimicrobial materials received a 2020 International CMF Design Award and that Langyi later led the drafting of a group standard covering inorganic metal-ion antibacterial and antiviral additives.
AntistinkMax® Deodorizing Materials
Odor management is another functional-material direction.
Shanghai Langyi describes its AntistinkMax® inorganic deodorizing material as having active functional groups on its surface that react with odor molecules including ammonia, acetic acid and hydrogen sulfide.
The company positions deodorizing functionality for applications where improving material quality, indoor comfort or consumer experience is important.
This complements antimicrobial technologies in sectors such as polymers, textiles, automotive interiors and consumer materials.
AntistaMax® Antistatic Materials
Shanghai Langyi also identifies AntistaMax® long-lasting antistatic agents among its functional material solutions.
Antistatic functionality can be important in polymer, film, fiber and electronic-material systems where uncontrolled static charge can interfere with processing or final product performance.
On its functional-fiber application page, Langyi specifically identifies antibacterial, antistatic, weather-resistant and multifunctional performance as development directions for functional fibers.
4. Fine Polymer Functional Materials
Shanghai Langyi’s current product center lists a broader group of fine polymer functional materials, including:
- SBR binder
- Multifunctional dispersant
- Specialty isocyanate resin
- Fluoroelastomer FKM
- Perfluoropolyether PFPE
This category is important because it moves beyond traditional additive chemistry into materials that directly influence bonding, dispersion, interfaces and polymer performance.
SBR Binders and Multifunctional Dispersants
Binders and dispersants play important roles in systems where particles, fillers or active materials need to remain uniformly distributed and mechanically integrated.
LANGYI’s inclusion of SBR binders and multifunctional dispersants also connects with its application coverage in lithium battery and other advanced material industries. The company’s lithium-battery application platform focuses on material technologies supporting performance, aging control and product reliability.
Specialty Isocyanate Resins
Specialty isocyanate resins expand the company’s polymer and crosslinking toolbox for customers requiring tailored resin performance.
FKM and PFPE
Shanghai Langyi also lists fluoroelastomer FKM and perfluoropolyether PFPE within the fine polymer functional material platform.
These products broaden Langyi’s material portfolio into fluorinated polymer systems and specialized high-performance material applications.
5. Advanced Carbon-Silicon-Based Functional Materials

The current official product page lists:
- Hard carbon
- Porous carbon
- Silicon-carbon materials
These materials support Langyi’s expansion into new-energy and advanced-material markets.
It is important to distinguish the current official product wording: Shanghai Langyi presently lists silicon-carbon, not silicon carbide, in this product category.
Advanced carbon materials are increasingly relevant to battery and energy-storage material development, which aligns with Shanghai Langyi’s official lithium-battery application platform.
