Does the plastic parts of automobiles withstand high temperature? How much is the minimum?
A POM made of synthetic resin, also known as poly formaldehyde resin, POM plastic, steel material; is a kind of white or black plastic particles, has the characteristics of high hardness, high wear resistance of the steel. Mainly used in gears, bearings, auto parts, machine tools, instrument parts, toys, such as the role of the skeleton products.
Plastic high temperature resistant mesh belt, POM material, general resistance to high temperature 100-120 degrees.
POM material properties:(1) POM is a crystalline plastics, density of 1.42g/cm3 steel, it is very good, commonly known as "steel".(2) it has excellent properties such as fatigue resistance, creep resistance, wear resistance, heat resistance and impact resistance, and has small friction coefficient and good self lubrication(3) POM is not easy to absorb moisture, water absorption rate is 0.22 ~ 0.25%, in a humid environment good dimensional stability, the shrinkage rate is 2.1% (larger), the injection size is difficult to control the temperature of 172 DEG, thermal deformation, POM POM has two kinds of different performance (homopolyformaldehyde temperature good point).
The specifications of the components in the car are defined by special vehicle rules, which are different from those of the ordinary ones.Plastic parts, according to dress position is also required different equivalent, general exposed parts (such as the internal and external surface acoustic speed plastic seal), is -40 to 105 degrees, and some car factory according to the actual temperature to ease the trafficking of -30 degrees to 85 degrees high temperature relaxation.
