【Amodel PPA美国苏威性能描述】

聚对苯二酰对苯二胺（PPA）塑料的热变形温度高达300℃以上，连续使用温度可达170℃，能满足您所需的短期和长期的热性能。它可在宽广的温度范围内和高湿度环境中保持其优越的机械性特性—强度、硬度、耐疲劳性及抗蠕变性。增韧吕级PPA结合优越的韧度与一定范围的硬度和柔性，在扣件中要求一次性使用的刚性、以及重复性使用中挠屈性的良好选择。同时提供特殊品级的产品应用于可喷涂和可电镀的表面，防火性、耐乙二醇性及反身性要求的应用。

【Amodel PPA美国苏威主要特征】

☆PPA强度、韧度和硬度优越性能，以及其良好的耐热件，耐化学性及抗开裂能力

☆PPA由于高温和高湿环境下仍能保持强度和硬度，可在传统的尼龙和聚酯所无法随的就用中替换金属

☆PPA塑料还具有优越的表面光泽性。可以对其进行着色而避免了表面喷涂，从而有助于降低表面划痕和刮痕的明显程度。

☆PPA塑料还具有良好的可加工性，并允许短的注塑循环时间

与PA46相比:

√PPA具有比PA46更高的热稳定性；

√PPA具有比PA46更好的CTI/耐电弧能和红外同流能力；

√PPA具有比PA46更好的耐化学性。

Huayun Plastic company PPA application due to the excellent physical, thermal and electrical properties of PPA Resin, especially the moderate cost, so that it has a wide range of applications. These properties, together with excellent chemical resistance, make the PPA a candidate for many uses in the automotive industry. The trend towards a better aerodynamics body design, coupled with higher performance motors, will raise the temperature of the engine case, making traditional thermoplastics less suitable. 

These new requirements make the PPA one of the candidate materials for making automotive headlight reflectors, housings, pulleys, sensor housings, fuel line components and electrical components. The Development Direction of electrical components is miniaturization and high temperature bonding, such as infrared bonding and vapor bonding, which needs the superior performance of PPA. The flame retardant PPA has excellent electrical properties, high HDT value, high bending modulus at high temperature, and thin-walled components that can be processed with minimal overflows, so it is suitable for making switchgear. Connector, brush holder and motor bracket. The mineral filler grade PPA is used for reflective surfaces and metallizing applications, including automotive headlamps, decorative fittings and hardware. The unreinforced impact modified PPA has excellent mechanical equilibrium and high temperature performance. Exceptional toughness and performance is minimally affected by humidity, and uses include oil field components, military supplies, sports equipment, fan blades and gears, and personal safety supplies.
