Product Description:

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.

Technical Parameters:

Applications:

Daily Necessities: Items such as food containers, suitcases, and furniture are must-haves in our everyday lives that we cannot do without.

Medical: In the medical field, disposable consumables like syringes, infusion tubes, and PCR plates play a crucial role in ensuring hygiene and safety protocols are met.

Industry: Industries rely on specialized components like automotive parts, building templates, and chemical pipelines to ensure smooth operations and efficiency.

Textile: The textile industry produces a variety of fiber products including clothing and blankets that are essential for comfort and warmth.
