ELASTOMER SCIENCE
THE TRI-CORE FOCUS
We engineer performance for extreme environments using three primary high-performance polymers:
Solid Silicone (VMQ):
Specializing in High-Consistency Rubber (HCR). Platinum-Cured (Medical-grade) and Peroxide-Cured systems for ultra-thin membranes and food-safe applications.
EPDM (Ethylene Propylene Diene Monomer):
Engineered for superior weather, ozone, and UV resistance. Ideal for automotive sealing and outdoor industrial gaskets.
NBR (Nitrile Butadiene Rubber):
High-performance oil and fuel resistance. Optimized for industrial seals, O-rings, and gaskets requiring long-term mechanical stability.
Note: We focus on Solid Elastomers to ensure maximum precision. We do not manufacture Liquid Silicone (LSR).
