PP sheet, also known as polypropylene (PP) sheet (PP pure sheet, modified PP sheet, reinforced PP sheet, PP welding rod), is a semi-crystalline material. It is harder than PE and has a higher melting point. Because homopolymer-type PP is very brittle at temperatures above 0°C, many commercial PP materials are irregular copolymers with 1 to 4% ethylene or clamp copolymers with higher rates of ethylene content.

Product Name: Copolymer type PP materials have lower heat distortion temperature (100°C), low transparency, low gloss, low rigidity, but have greater impact strength.The strength of PP increases with increasing ethylene content.The Vicat softening temperature of PP is 150°C. The Vicat softening temperature of PP is 150°C. The Vicat softening temperature of PP is 150°C. The Vicat softening temperature of PP is 150°C. The Vicat softening temperature of PP is 150°C. Due to the high degree of crystallinity, this material has good surface stiffness and scratch resistance properties.PP does not suffer from environmental stress cracking. Typically, PP is modified by adding glass fibers, metal additives, or thermoplastic rubber.The flow rate MFR of PP ranges from 1 to 40.PP materials with low MFR have better impact characteristics but lower ductile strength. For the same MFR, the copolymer type is stronger than the homopolymer type. Due to crystallization, the shrinkage of PP is quite high, generally 1.8 to 2.5%. And the directional uniformity of shrinkage is much better than materials such as PE-HD. Adding 30% glass additive can reduce the shrinkage to 0.7%. Both homopolymer-type and copolymer-type PP materials have excellent resistance to moisture absorption, acid and alkali corrosion, and solubility. However, it has no resistance to aromatic hydrocarbon (e.g., benzene) solvents, chlorinated hydrocarbon (carbon tetrachloride) solvents, etc. PP also does not have oxidation resistance at high temperatures like PE.
Plate Classification
- Pure PP sheet
Small density, easy to weld and process, with superior chemical resistance, heat resistance and impact resistance, non-toxic, tasteless is the most environmentally friendly requirements of one of the engineering plastics. The main colors are white, microcomputer color, other colors can also be customized according to customer requirements. Applications: Acid and alkali resistant equipment.
- Polypropylene (PP) Extrusion Sheet
It is a plastic sheet made of PP resin added with various functional additives through extrusion, calendaring, cooling, cutting and other processes.
- Glass Fiber Reinforced PP Sheet
Glass fiber reinforced PP board (FRPP board): After 20% glass fiber enhancement, in addition to maintaining the original excellent performance, strength, rigidity, etc. are doubled compared with PP, and has good heat resistance, low temperature impact, corrosion resistance to arc, low shrinkage. Especially suitable for chemical fiber, chlor-alkali, petroleum, dyes, pesticides, food, medicine, light industry, metallurgy, sewage treatment and other fields.
PPH sheet, Beta (β)-PPH single side laminated nonwoven sheet. (β)-PPH products have excellent heat and oxygen aging resistance, long service life, and good mechanical properties. It has been successfully used in the production of plates, and the advanced technology is among the leading ones in China. These products can be used for filter plates and spiral-wound containers, for FRP winding liner plates, for storage, transportation and anti-corrosion systems in the petrochemical industry, for water supply, water treatment and drainage systems in power plants and waterworks, and for dust removal, scrubbing and ventilating systems in steel mills and power plants.
Characteristics and Uses
PP extrusion sheet has light weight, uniform thickness, smooth and flat surface, good heat resistance, high mechanical strength, excellent chemical stability and electrical insulation, non-toxicity, etc. PP sheet is widely used in chemical containers, machinery, electronics, electrical appliances, food packaging, pharmaceuticals, decoration and water treatment, etc. The practical temperature of PP sheet can reach 100 degrees.
Scope of Application
Acid and alkali resistant equipment, electroplating equipment, solar photovoltaic equipment, environmental protection equipment, wastewater, waste gas discharge equipment, washing tower, clean room, semiconductor plant and its related industrial equipment, is also the first choice of material for the manufacture of plastic water tanks, which PP thick plate is widely used in stamping plate, press pads and so on.

- Recycling bins, including reusable recycling bins for various industries, fruit and vegetable packing bins, clothes storage bins, stationery bins;
- industrial boards, including wire and cable outer wrapping protection, glass, steel plate, all kinds of articles outer wrapping protection, padding board, shelf, partition board, bottom board, etc;
- protection board, cardboard, three clipboard protection construction of building materials in the era of gone, with the progress of the times and taste, to ensure that the integrity of the decorative design in the completion of the opening of the completion, should be given appropriate protection in order to maintain the operation of the economy, safety and convenience, and other building elevators, flooring before acceptance of the protection.
- Electronic industry protection. Conductive packaging products are mainly used in IC wafers, IC packaging, testing, TFT-LCD, optoelectronics and other electronic parts of the packaging, the purpose is to avoid other charged items in contact with them, resulting in parts due to charge friction spark damage. There are also conductive, anti-static plastic plates, crates and so on. PP board can be used in addition to the above products, but also used in washing machine backplane, refrigerator insulation layer, frozen food, medicine, sugar and wine packaging. Can also use the hollow plate production line to produce PE hollow plate to supply urban construction, rural areas need to keep the greenhouse partition.
