PP sheet is short for polypropylene sheet. Polypropylene granules are dyed, plasticised at high temperature and extruded into polypropylene sheet.PP sheet has chemical resistance, heat resistance, electrical insulation, high strength mechanical properties and good high abrasion resistance processing performance. It is one of the most widely used and fastest growing resins in the world. Its main advantages are:
Corrosion resistance. Dilute alkalis and acids do not react with PP, which makes it an ideal container for such liquids.
Elasticity and toughness: PP is elastic within a certain range of deflection and deforms plastically without cracking at the beginning of the deformation, so it is often considered a “tough” material.
Fatigue resistance. PP retains its shape after many twists and bends.
Insulation: PP has high electrical resistance and is a good insulating material.
Transparency. It can be made into transparent colours, but it is usually made into natural opaque colours with a certain colour transmittance.
PP plastic sheet is a semi-crystalline material, PP plastic sheet relative to PE sheet to be harder, higher melting point.PP plastic sheet has a certain degree of heat resistance, low-temperature impact, anti-corrosion arc resistance and low shrinkage, is the ideal building sheet in modern construction.PP plastic sheet is also the most environmentally friendly engineering plastics, non-toxic, tasteless, environmentally friendly and healthy. Smooth and flat surface, uniform thickness, light weight, with a certain degree of heat resistance and mechanical strength, because of these characteristics, PP sheet has a wide range of applications, able to produce advertising billboards, recycling boxes, but also as an industrial board to play a role in packaging and protection, in addition to PP plastic sheet in the protection of the electronics industry also has a wide range of applications, such as IC wafers, IC encapsulation, testing, optoelectronics and other electronic parts of the packaging.
