Plastics & Polymers Chemistry by Function

Jump straight to the chemistry you need — each guide explains the types, how to select, and routes you to the specific grades we supply.

Flame Retardants
Match the flame-retardant chemistry to your polymer and target rating - ATH/MDH mineral hydroxides, phosphate esters, and halogen-free intumescents - by loading, processing temperature, and smoke/UL requirements.

HALS & Light Stabilizers
Specify the light-stabilizer package that keeps polyolefins, TPO and engineering resins from chalking and embrittling outdoors - monomeric, polymeric and NOR HALS chosen by service life, thickness and processing.
Explore →
Epoxy Curing Agents
Choose the hardener that sets your thermoset's cure profile and Tg - amine, polyetheramine, anhydride, imidazole and latent systems for composites, casting and encapsulation.

Polyurethane Catalysts
Balance gel, blow and trimerization with the right amine/metal catalyst for flexible and rigid foam or CASE - tuned to cream/rise time and demold.
Explore →
Silicones
Silicone process aids, slip and anti-block additives, and mold-release fluids that improve melt flow, surface slip and demolding in compounded and molded polymers.
Explore →
Photoinitiators
Select Norrish Type I/II and LED-cure photoinitiators for UV/EB-cured resins, photopolymer/3D-print formulations and radiation-cure adhesives - by cure depth, surface cure and yellowing.
