Machinery Industry POM Sheet

POM Sheet 

Ⅰ.Material Introduction

POM  Acetal is renowned for outstanding  hardness,mechanical strength and rigidity.Therefore, this polyacetal  material is the ideal substitute for polyacetal material is  the ideal substitute for copper, coated zinc,steeland other metallic materials .This engineering thermoplastic has  smooth and gloss surface, and is easy to burn.When this plastic marterials burns, the upper flame is in yellow and the bottom is in blue, generating irritant  formaldehyde flavor and fishlike smell.

Ⅱ. Material Strength

♦ Prominent surface stiffness and impact resistance.

♦ Low  coefficient of friction, self-lubricating and  outstanding abrasion resistance,thus being well-suited for gear production.

♦ High shrinkage ratio yet extreme dimensional stability.

♦ Good electrical and dielectric properties.

♦ Impressive resistance to solvent and stress-cracking.

♦ Remarkable creep resistance and returns back to original shape in a fast manner when external forces are withdrew.

♦ High thermal and  chemical resistance.

♦ Low moisture absorption and no pores.

III. Material Application

♦ Machinery industry:gear,roller,bearing ring, connecting rod and impeller blade.

♦ Vehicle:valve body for water tank,gear housing and covering plate for radiator.

♦ Electronics:housing for electric-powed tool,parts for TV and fax machine.

♦ Other:toy,parts for window and door.
