Mô tả sản phẩm

Bình luận & Đánh giá

Radel® R-5900 polyphenylsufone (PPSU) offers medium melt viscosities for long flow lengths and greater injection molding ease. It also provides exceptional hydrolytic stability and toughness that is superior to that of other commercially available, high-temperature engineering resins. It offers high deflection temperature and outstanding resistance to environmental stress cracking. The resin is inherently flame retardant and has excellent thermal stability and good electrical properties.
