Amorphous – HTP
High Performance Engineering (Amorphous)
High Temperature Plastic
PPSU – Polyphenylsulfone – Offers better impact resistance and chemical resistance than polysulfone (PSU) and polyetherimide (PEI). A high-heat, high-performance resin with formulations exhibiting very good hydrolytic stability, excellent resistance to acids and bases and good resistance to stress cracking against a broad range of chemical environments. Inherently flame retardant.
PEI – Polyethylenimine – Are high performance polymers that combine excellent thermal properties, exceptional dimensional stability, inherent flame retardance and good chemical resistance. PEI resin additives have a high glass transition temperature together with excellent long-term heat resistance.
PESU – Polyethersulfone – A high strength, high temperature resistant polymer, with toughness and outstanding long term creep resistance. PESU has the ability to maintain much of its strength at elevated temperatures, and can be repeatedly steam sterilized without significantly affecting physical properties. It has good hydrolysis and chemical resistance and is unaffected by non-oxidizing acids, bases, aqueous solutions, aliphatic hydrocarbons and alcohols.
PSU – Polysulfone – A rigid, high-strength, semi-tough, transparent plastic that offers higher heat resistance and better hydrolytic stability than polycarbonate (PC). It retains its good mechanical properties when exposed to steam and other sterilization techniques.
