Product Description

 

Product Description

POM material is a kind of synthetic resin material, also called polyacetal resin. It is a white or black plastic particle. Its regular molecular structure and crystallinity make it have excellent physical and mechanical properties. It is often used to replace metal plastics. It has the characteristics of high hardness, light weight, high rigidity and high wear resistance performance.
 

Polyformaldehyde is a hard and dense material with a smooth and shiny surface, light yellow or white, and the thin-walled part is translucent. The combustion characteristics are that it burns easily and continues to burn after leaving the fire. The upper end of the flame is yellow and the lower end is blue. It melts and drips, and has a strong pungent formaldehyde smell and fishy smell. Polyformaldehyde is a white powder, generally opaque, with good colorability, specific gravity of 1.41-1.43 g/cm3, molding shrinkage of 1.2-3.0%, molding temperature of 170-200°C, and drying conditions of 80-90°C for 2 hours. The long-term heat resistance of POM is not high, but it can reach 160°C in the short term. The short-term heat resistance of homopolymerized POM is more than 10°C higher than that of copolymerized POM, but the long-term heat resistance of copolymerized POM is about 10°C higher than that of homopolymerized POM. It can be used for a long time in the temperature range of -40ºC~100ºC. POM is easily decomposed, with a decomposition temperature of 240 degrees. During decomposition, irritating and corrosive gases are produced. Therefore, mold steel should be made of corrosion-resistant materials.
