Product Description

Product Description

PPSU is an amorphous thermal plastic with high transparency and high hydrolytic stability. Products can be subjected to repeated steam disinfection. PPSU resin is a linear polymer with a slight amber color. In addition to strong polar solvents, it is stable to general acids, bases, salts, alcohols, aliphatic hydrocarbons, etc. Partially soluble in ester ketone, aromatics, soluble in halocarbons, DM. Good rigidity and toughness, temperature resistance, heat resistance to oxidation, excellent creep resistance, corrosion resistance to inorganic acid, alkali, salt solution, ion radiation resistance, non-toxic, insulation and self-extinguishing good, easy molding processing.
