PP board is made of polypropylene material, its hardness is higher than PE board, that is, polyethylene, strong acid and alkali resistance, so it can become the main raw material for the production of acid and alkali resistance equipment. It can be seen in various industrial pigments and high-strength acids and bases. The processed container has stable function and good reliability. Polypropylene sheet has impact resistance, corrosion resistance, high heat resistance, non-toxic and odorless, smooth and beautiful appearance, low density, light weight, no poisonous gas during welding, and simple processing. Polypropylene board has a low thermal distortion temperature (100°C), low transparency, low gloss, and low rigidity.
Polypropylene board has high impact strength, and the strength of polypropylene increases with the addition of ethylene content. Polypropylene board has high hardness and high melting point. The shrinkage rate of the polypropylene board is appropriately high. Because polypropylene sheet is a semi-crystalline material, the shrinkage rate is generally 1.8~2.5%. And the direction uniformity of shrinkage is much better than that of PE-HD and other materials.
Polypropylene board plastic gusset is made of polypropylene board, which is light in weight, simple in equipment, waterproof, and anti-moth. The appearance of the pattern is also changed very much, and it is resistant to pollution, easy to clean, and has excellent functions of sound insulation and heat insulation. It is the flame-retardant material involved in the new process, so that it can be extinguished away from the fire, and it is safer to use. The disadvantage is that the service life is relatively short compared with the ceiling panels of metal materials.
China Xicheng Environmental Protection Equipment Company is mainly engaged in the design and construction of PP boards, PP pipes, various PP pipe fittings, washing towers, activated carbon adsorption boxes, and other ventilation projects. The products are exported to many countries all over the world, and the quality and service are much higher than those of peers.
Polypropylene can be used in injection molding, extrusion, thermoforming, rotomolding, foaming and other processing methods to produce products with different uses. Because various processing methods have different requirements for the melting function of polypropylene, it has formed injection molding grade and extrusion molding. Grade, fiber grade, rotomolding grade, etc. to meet different processing requirements. The board has the characteristics of light weight, uniform thickness, lubricating appearance, good heat resistance, high mechanical strength, good chemical stability, and non-toxic electrical insulation.
The chemical function of polypropylene PP sheet is stable. In addition to being corroded by concentrated sulfuric acid and concentrated nitric acid, it is stable against other chemical reagents, but low-molecular-weight aliphatic and aromatic hydrocarbons can soften polypropylene and have swelling properties. And chemical stability also improves with the increase of crystallinity. Therefore, it is suitable for the production of chemical pipelines and pipe fittings, and has an outstanding anti-corrosion effect.
