Copolymer type PP materials have lower heat distortion temperature (100°C), low transparency, low gloss, and low stiffness, but have greater impact strength.The strength of PP increases with increasing ethylene content.PP has a Vicat softening temperature of 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.
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 the process of extrusion, calendaring, cooling and cutting.
Glass Fiber Reinforced PP Sheet
Glass fiber reinforced PP sheet (FRPP sheet): After 20% glass fiber reinforcement, 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, arc resistance, 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.
Scope of Application
Acid and alkali equipment, electroplating equipment, solar photovoltaic equipment, environmental protection equipment, wastewater, waste gas discharge equipment, washing tower, clean room, semiconductor plants and other related industrial equipment, but also the first choice for the manufacture of plastic water tanks, which PP thick plate is widely used in stamping plates, press pads and so on.
- advertising signboards;
- recycling bins, including reusable recycling bins for various industries, vegetable and fruit packaging bins, clothes storage bins, stationery bins;
- industrial boards, including wire and cable outer wrapping protection, glass, steel plate, all kinds of items outer wrapping protection, padding, shelves, partitions, baseboards and so on;
- 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.
