产品说明

Veradel A-704P (PESU) is a powder designed for dissolving or dispersing into solutions. It can also be ground to smaller particle size, or blended with other solid particles.

PESU offers excellent toughness and outstanding hydrolytic resistance. It resists attack from steam, boiling water and mineral acids. Cast films or coatings of PESU are transparent and have additional desirable properties including long term thermal stability, excellent metal adhesion and formability and inherent flame resistance.

Typical applications include high-temperature coating formulations, advanced high-temperature composites and specialty adhesives. Veradel A-704P is relatively low in molecular weight and viscosity. A higher molecular weight and viscosity grade is available as A-304P. This grade was formerly marketed as Radel® A PESU
