Polymers & Plastics
Driving Material Innovation with Quality Monomers and Additives
At WE Chem, we deliver a focused portfolio of acrylates, methacrylates, initiators, and additives essential for advanced plastic and polymer production. Our selection includes monomers like MMA, EMA, and iBUMA for rigidity and optical clarity, soft monomers like iBA and tBA for flexibility and toughness, and crosslinkers such as allyl methacrylate and GMA for strength and chemical resistance.
To ensure controlled polymerization, we supply high-purity initiators like ammonium, sodium, and potassium persulphate (APS, SPS, PPS), suitable for emulsion systems and radical polymerization. Pigments like chromoxide green and modifiers such as stearyl acrylate enhance color stability and processing behavior in plastics and rubber.
