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、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。
Because PPA can still maintain strength and hardness under hightemperature and high humidity, it can be used as a substitute fortraditional nylon and polyester
It has excellent surface gloss when replacing metal. It can becolored to avoid surface spraying, thus helping to reduce thesurface
Scratches and scratches. High temperature nylon with mechanicalproperties, thermal deformation temperature of 280 ° C, continuoususe temperature of 170 ° C
It can meet the required short-term and long-term thermalperformance. It can maintain its advantages in a wide temperaturerange and high humidity environment
More mechanical properties - strength, stiffness, fatigueresistance and creep resistance. It also has chemical resistanceand low water absorption. can
Provide special grades such as low temperature impactresistance, flame retardant, glycol resistance, sprayable andelectroplating.
PPA has excellent strength, toughness and hardness, as well asits good heat resistance, chemical resistance and crackingresistance
It can still maintain strength and hardness under hightemperature and high humidity, and can replace metal in the usethat traditional nylon and polyester cannot follow
PPA plastic also has excellent surface gloss and can be coloredto avoid surface spraying, thus helping to reduce
The apparent degree of surface scratches and scratches, goodmachinability and short injection cycle time are allowed comparedwith PA46:
√ PPA has higher thermal stability than PA46; √ PPA has betterCTI/arc resistance and infrared co-current capacity than PA46;
√ PPA has better chemical resistance than PA46.
