Product Details

pom plastic material

Exterior:

The appearance of POM raw material is light yellow or white translucent or opaque powder or granule, hard and dense, similar to ivory, and the surface of the product is smooth and shiny.pom plastic material

Flammability

It is flammable and can continue to burn after catching fire. Its oxygen index is only 14-16. The upper end of the flame is yellow, and the lower end is blue. The droplets stimulate formaldehyde and fishy smell. Note that it is poisonous.

Breathability

The permeability of POM raw materials is very small, only a small part of PE.

Shrinkage

The high crystallinity of the POM raw material leads to a higher shrinkage rate, which can be as high as 2% to 3.5%.

Mechanical behavior

The mechanical properties of POM raw materials are very good, the modulus of elasticity is high, the friction coefficient is low and stable, the wear resistance is good, and the self-lubricating property is good. Has high hardness and rigidity. Very close to metal. Good dimensional stability, low water absorption, resistance to repeated impacts and small changes in strength. Its tensile strength and modulus are close to steel. Good fatigue strength. It is a thermoplastic material with better fatigue resistance. It can withstand more than one million repeated loads. High resistance to creep and stress relaxation. Mechanical properties change little with temperature, and copolymerization is slightly larger than homopolymerization.
