Detailed Product Description

High-precision POM(Delrin) ball 3.175mm -50.8mm (3/32"~2")

POM plastic
(Delrin) (Cup Steel ~ Trane)
English name: Polyoxymethylene (Polyformaldehyde)
Weight :1.41-1.43 grams / cubic centimeter :1.2-molding shrinkage rate 3.0% molding temperature :170-200 drying conditions :80-90 2 hours

Better overall performance properties of materials, strength, high stiffness, good wear resistance of friction, absorbent small, dimensional stability, but poor thermal stability and easy to burn easily in the atmosphere aging exposure. Suitable for the production of friction wear-resistant parts, transmission parts, as well as the chemical industry, instrument parts
Forming properties:

1. Crystalline material, melting a narrow range, melting and solidification fast, slightly lower than the melting temperature materials that happen crystallization temperature. Medium mobility. Hygroscopic small, without drying treatment.
2. A low friction coefficient, good elasticity, easy to produce plastic parts surface wrinkle patterns of surface defects.
3. Vulnerable to decomposition, decomposition temperature of 240 degrees. Decomposition has happened irritating and corrosive gases. Therefore, mold steel corrosion resistance appropriate selection of materials.
