Wear Resistant Polyoxymethylene Pom Plastic CNC Machining Board
1. Different properties: Polypropylene (PP) extruded sheet is a plastic sheet
made of PP resin added with various functional additives through extrusion,
calendering, cooling, cutting and other processes. POM polyoxymethylene is
a linear polymer with no side chains, high density and high crystallinity.
2. The characteristics are different: POM plastic has a slightly lower stability
to acid and alkali; while the copolyformaldehyde has lower density, crystallinity,
melting point and strength, but has good thermal stability. PP plastic board is
a semi-crystalline material, which is harder than PE and has a higher melting point.
