Introduction to PPA materials

Plastic: high temperature resistant nylon PPA hot deformation temperature up to 300 ° C, continuous use temperature up to 170 ° C, can meet your needs of short-term and long-term thermal properties.

It can maintain its superior mechanical properties strength, hardness, fatigue resistance and creep resistance in a wide temperature range and high humidity environment. Toughened Lu grade PPA combines superior toughness with a certain range of hardness and flexibility, which requires disposable rigidity in fasteners and good flexibility in repeated use. At the same time, special grade products are provided for application on the surface that can be sprayed and electroplated, and the application of fire resistance, ethylene glycol resistance and reflexivity requirements.

Performance:

The strength, toughness and hardness of PPA are superior, as well as its good heat resistance, chemical resistance and cracking resistance

Since PPA can maintain strength and hardness in high temperature and high humidity environment, it can replace metal in traditional nylon and polyester

PPA plastic also has superior surface gloss. It can be colored to avoid surface spraying, which helps to reduce the obvious degree of surface scratches and scratches.

PPA plastic also has good processability and allows short cycle time

Compared with PA46:

The thermal stability of PPA was higher than that of PA46;

√ PPA has better CTI / arc resistance and infrared CO current capability than PA46;

The chemical resistance of PPA was better than that of PA46;

application

Vehicle components, including fuel, transmission and engine systems, can reduce weight, reduce cost and provide long service life;

Chip set and socket, cup body welding support;

Chip capacitor, switch and micro horn, making high-density printed circuit board connector;

It is used in occasions with high wear resistance requirements, such as non lubricated bearings, seals, bearing isolation rings and reciprocating compressor parts;

Connector, controller, sensor, motor and other key electronic components
