Lihat Profil Seller40% talc-filled polypropylene compound with good dimensional stability and heat resistance for automotive under-hood applications
STERLENE™ CMW402 is a specialty 40% talc-filled polypropylene compound (PP-TD40) developed for automotive under-hood applications that require high stiffness, good dimensional stability, and reliable heat resistance. With a higher talc content compared to PP-TD20 grades, CMW402 provides increased rigidity and reduced deformation under thermal and mechanical stress. Supplied in pellet form, this grade is designed for injection molding and is available in black, natural, or customized colors.
