Product Description:
Polypropylene (PP) Overview:
Polypropylene (PP) is a semi crystalline thermoplastic polymer that is created by polymerizing propylene monomer. Its chemical formula is (C3H6) ₙ, and it has a density of 0.89-0.92 g/cm³, making it one of the thermoplastic resins with the lowest density.
Properties of Polypropylene:
Polypropylene has a melting point range of 164~176 ℃, and an operating temperature range of -30~140 ℃. It is known for its lightweight nature, as well as its high wear resistance and resistance to chemical corrosion.
Features:
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
