Name: PP (Polypropylene)
Tensile Strength: 30 MPa Water Absorption: 0. 01%
Density: 0. 90--0. 91g/cm3 Shrinkage Rate: 1%~2.5%
Polypropylene is a thermoplastic resin prepared by polymerization of propylene.
1. High crystallinity and regular structure, so it has excellent mechanical properties, strength, stiffness, hardness and heat resistance than polyethylene, molding processing performance is good.
2., it has high heat resistance and does not deform at 150 C without external force.
3. Chemical stability is very good, does not absorb water, is not affected by humidity, corrosion resistance and most chemicals do not react.
