Laser plastic welding technical materials Knowledge sharing | Modified engineering plastics
【 Application 】
Automobile lightweight makes the amount of automobile modified plastics increase, plastics can not only reduce the overall quality of the car, improve the power, reduce the emissions of the car, but also greatly reduce its production costs. As a special engineering plastic PPS is favored by automotive Oems, and the use of automotive parts is also a wide range of applications of PPS.
【 Definition 】
PPS is a kind of semi-crystalline polymer material, which has the characteristics of high and low temperature resistance, corrosion resistance, flame retardant, dimensional stability, high mechanical strength and excellent electrical properties. It is a special engineering plastic, known as the "world's sixth largest engineering plastic" and one of the "eight" aerospace materials.
PPS resin through enhancement, filling modification, can be produced with high temperature resistance, high strength, wear-resistant, conductive, thermal and other functions of modified engineering composite materials, is widely used in new energy vehicles, electronic appliances, 5G Many industries, such as communications, national defense, aerospace, medical equipment, petrochemical, environmental protection industry, are indispensable new materials for the upgrading of traditional industries and the development of high-tech, and meet the development requirements of "replacing steel with plastic" and "lightweight".
【 Characteristic 】
It's DIFFERENT from everyone else
1. Excellent heat resistance
The melting point is about 280°C, and the operating temperature is -60°C~260°C
2. Flame retardant
Self-flame retardant, up to UL94-V0 level
3. Chemical corrosion resistance
It is basically insoluble in any organic solvent below 200°C
4. Good dimensional stability
Small shrinkage, low water absorption, small linear thermal expansion coefficient,
5. Good mechanical properties
High mechanical strength, good toughness
6. Excellent electrical performance
It still has excellent electrical properties under high temperature, high humidity and high frequency conditions
7. Good wear resistance
Low friction coefficient, small wear
8. Light weight
The density is 1.2~2.0g/cm ", much lower than that of metal materials
9. Other features
Heat conduction, antistatic, electroplating, low dielectric, etc
