In-House Rubber Compounding Across 9+ Polymer Families
We don't buy compounds. We engineer them — with Japanese formulation partners, across 30 years and [TBD: 200+] proprietary formulations. Custom chemistry for unique application requirements is our core strength, not an exception.

Polymer Families We Compound In-House
Ordered by current sector priority. Each family is available in multiple proprietary formulations developed over 30 years of Sino-Japanese collaboration.
HNBR (Hydrogenated Nitrile)
EV thermal management hoses, high-temperature automotive seals, fuel-system O-rings. Low compression set under sustained heat and oil exposure.
TECHNICAL SPECIFICATIONS →FKM (Fluoroelastomer)
Chemical, fuel, and high-temperature resistance for aerospace, semiconductor process, and high-performance automotive applications.
TECHNICAL SPECIFICATIONS →FFKM (Perfluoroelastomer)
Our flagship co-development compound. Aggressive plasma etch, ALD/CVD chambers, high-purity gas delivery in semiconductor manufacturing.
TECHNICAL SPECIFICATIONS →EPDM (Ethylene Propylene Diene)
Weather, ozone, and steam resistance. Used for EV battery pack seals, charging infrastructure, BESS cabinets, and outdoor industrial enclosures.
TECHNICAL SPECIFICATIONS →NBR (Nitrile Rubber)
Cost-effective oil resistance for hydraulic, pneumatic, pump, and general industrial sealing applications.
TECHNICAL SPECIFICATIONS →ACM (Polyacrylate)
Automotive transmission seals. Outstanding ATF (Automatic Transmission Fluid) resistance with continuous service to 175°C.
TECHNICAL SPECIFICATIONS →AEM (Ethylene Acrylate)
Automotive heat ducts, turbocharger hoses, and engine air management seals. Heat + oil combined resistance.
TECHNICAL SPECIFICATIONS →Silicone (HCR — Heat Cured Rubber)
Industrial-grade silicone with -60°C to +230°C temperature range. FDA-compliant grades on request for food-contact and industrial equipment applications — not for medical implant use (we do not hold ISO 13485).
TECHNICAL SPECIFICATIONS →LSR (Liquid Silicone Rubber)
Precision overmolding and liquid injection for tight-tolerance components. Industrial and equipment applications where geometric precision matters.
TECHNICAL SPECIFICATIONS →Material Performance Matrix
Quick comparison across our four most-specified families. Detailed cards above for HNBR, FFKM, ACM, AEM, LSR.
| Property | FKM | EPDM | NBR | Silicone (HCR) |
|---|---|---|---|---|
| Temp Range (°C) | -20 to +200 | -50 to +150 | -40 to +120 | -60 to +230 |
| Oil Resistance | Superior | Poor | Excellent | Fair |
| Chemical Resistance | Excellent | Good | Fair | Good |
| Durability Index | High | High | Medium | Medium |
