Polypropylene (PP) is a semi crystalline thermoplastic polymer produced by polymerizing propylene monomer. Its chemical formula is (C3H6) ₙ, and it has a density of 0.89-0.92 g/cm³, which is the lowest among thermoplastic resins.
The melting point range of PP is 164~176 ℃, and its operating temperature range is -30~140 ℃. Some of its key characteristics include lightweight, high wear resistance, and resistance to chemical corrosion.
Key Features
Physical performance:
It is a white waxy solid, non-toxic and odorless, with a transparent appearance and lightweight texture. Excellent fatigue resistance, suitable for applications with repeated bending or twisting, with a water absorption rate of only 0.01% and excellent water stability.
Chemical properties:
Acid, alkali, alcohol and other corrosive substances, but weak tolerance to aromatic solvents (such as benzene), good biocompatibility, in line with medical material safety standards.
Processing performance:
It can be formed through extrusion, injection molding, blow molding and other processes, with a shrinkage rate of 1.8%~2.5% (reduced to 0.7% by adding glass fiber), easy to dye, but attention should be paid to the possible precipitation of small molecule substances at high temperatures.
