POM – Polyacetal
POM is a stiff, hard and springy material, which is suitable for machining. It is short-chipped, and a high surface finish can be achieved. POM is the most universally used material.
POM is found in two types – H and C. Where POM C is the standard today. Despite the hardness, POM has a high elasticity and impact resistance. In a short period of time POM can withstand high temperatures up to 140°C. Longer term exposure to, or use in hot water over 65°C, can cause crispness and crazing (hydrolysis). POM is found in different modified types. POM as semi-finished is manufactured by extruding and is delivered in the colors: nature (white) and black, where black is the most UV-stable.
The food industry uses POM to a great extent, as the material is easy to clean and will not be significantly affected by those cleaning products, that usually are used.
