Dampproof PP Shrink Wrap

China suppliers manufacturers of Xiamen Guanhua is produced Dampproof PP Shrink Wrap. Dampproof PP Shrink Wrap is polypropylene film, a thermoplastic resin prepared by polymerization of propylene. Usually thicker, tougher, higher tensile strength, can be used for greenhouse film, load-bearing bags and so on.

Dampproof PP Shrink Wrap is a non-toxic, odorless, tasteless milky white highly crystalline polymer with a density of only 0.90 --" 0.91g /cm3, which is one of the lightest varieties of all plastics at present. It is particularly stable to water, its water absorption rate in water is only 0.01%, and its molecular weight is about 81,150,000.

Polypropylene cannot resist oxidation at high temperatures. Biaxial polypropylene film in plastic products packaging materials occupy an extremely important position, according to statistics, the world for the field of packaging plastics accounted for about 35% of the total consumption of plastics.

Good performance: Dampproof PP Shrink Wrap has excellent mechanical properties because of its high crystallinity and regular structure. The absolute value of the mechanical properties of polypropylene is higher than that of polyethylene, but it is still a low variety in plastic materials, and its tensile strength can only reach 30 MPa or a slightly higher level.

Dampproof PP Shrink Wrap Characteristic: Non-toxic, tasteless, low density, strength, stiffness, hardness and heat resistance are better than low pressure polyethylene, can be used at about 100℃. It has good dielectric properties and high frequency insulation and is not affected by humidity, but becomes brittle at low temperature, is not wear-resistant, and is easy to age.

Suitable for making general mechanical parts, corrosion-resistant parts and insulating parts. Common organic solvents such as acids and alkalis have little effect on it and can be used in eating utensils.
