聚对苯二甲酸乙二酯（PPA）
聚对苯二甲酸乙二酯由芳香酸与脂肪族二胺反应形成，并使用对苯二甲酸和间苯二甲酸的组合生产
聚邻苯二甲酰胺又称PPA，是一种高耐热性的半芳香聚酰胺
由于其低吸湿性，PPA在各种条件下，如恶劣的化学环境和极端温度条件下，表现出优异的保持性能。它们还表现出出色的刚度和抗蠕变性能
由于其芳香结构，与其他聚酰胺相比，聚对苯二甲酸乙酰胺（PPA）具有一些优越的性能，其一些性能如下所示
提高了尺寸稳定性
提高了耐溶剂性和耐水解性
更好的高温机械性能保持力

Polyphthalamide (PPA)
Polyphthalamides are formed by reaction of aromatic acids with aliphatic diamines and produced using a combination of terephthalic acid and isophthalic acids.
Polyphthalamide also known as PPA is a high heat resistance semi-aromatic polyamide.
With its low moisture pick up, PPA demonstrates excellent retention of performances in a wide range of conditions, such as harsh chemical environment and extreme temperature conditions. They also demonstrate excellent stiffness and creep resistance.
Thanks to their aromatic structure, Polyphthalamides (PPA) offer several superior performances compared to other polyamides, Some of its properties are listed below.
Improved dimensional stability
Improved solvent and hydrolysis resistance
Better high temperature mechanical property retention
is one of the professional low moisture ppa resin with glass fiber ppa plastic raw material price manufacturers, you can order high quality low moisture ppa resin with glass fiber ppa plastic raw material price at good price from our factory.
