SUMIKAEXCEL 4800P

Grade Information

スミカエクセル 4800Pは、溶液中で溶解または分散させるために設計されたポリエーテルスルホン(PESU)のパウダーグレードです。グレード名は分子量と関連しており、4800Pは中間の分子量を持っています。分子量と溶液の粘度には相関関係があります。

SUMIKAEXCEL PES has excellent toughness, high heat resistance, high dimensional stability, hydrolysis resistance, and chemical resistance. It is also transparent, has long-term heat stability, excellent metal adhesion, moldability, and inherent flame retardancy.
