| Veradel 3000P 、 3100P 、3200P 、 3400P 和3600P 均为粉状聚醚砜（PESU ），用于溶解或分散到溶液中。也可以磨成较小小的颗粒或与其它固体颗粒混合。这些牌号分子量不同，3000P的最高，3600P的最低。分子量和溶液粘度直接相关。 PESU具有优良的韧性和卓越的耐水解性。耐蒸汽、沸水和无机酸的攻击。流延薄膜或PESU涂层呈透明状，具有其它所需性能，包括长期热稳定性、优异的金属粘合性、可成形性和固有的阻燃性。 一般用于高温涂料配方、膜、先进耐高温复合材料和特种粘合剂。 该牌号以前用Gafone™ PESU销售。 Veradel® 3000P, 3100P, 3200P, 3400P and 3600P are polyethersulfone (PESU) powders for dissolving or dispersing into solutions. They can also be ground to smaller particle size or blended with other solid particles. The grades differ by their molecular weights, with 3000P the highest and 3600P the lowest. There is a direct correlation between molecular weight and solution viscosity. 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, membranes, advanced high-temperature composites, and specialty adhesives. This grade was formerly marketed as Gafone™ PESU |
