CA-87 CLEAR is a specialty grade polymer designed for extrusion processes. This polymer offers the highest heat resistance and stiffness. The typical applications include modifier for ASA, AES resins. CA-87 CLEAR has an excellent heat resistance because of its monomeric composition and polymer’s molecular weights. This polymer also possesses the best chemical resistance and stiffness.
