PP board, also known as polypropylene (PP) board (PP pure board, modified PP board, reinforced PP board, PP welding rod), is a semi-crystalline material. It is harder and has a higher melting point than PE. Since homopolymer PP is very brittle at temperatures above 0 °C, many commercial PP materials are random copolymers with 1 to 4% ethylene added or pincer copolymers with higher ethylene content. Chinese name PP board Alias Polypropylene (PP) board Type Semi-crystalline material Features Hard and high melting point content.
Features and uses
Scope of application
Product Name: Copolymerized PP material has low heat distortion temperature (100°C), low transparency, low gloss, low rigidity, but has stronger impact strength. The strength of PP increases with the ethylene content. 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. PP does not have environmental stress cracking problems. Typically, PP is modified by adding glass fibers, metal additives or thermoplastic rubber. The flow rate MFR of PP is between 1~40. PP materials with low MFR have better impact resistance, but lower ductility. For the same MFR material, the strength of the copolymer type is higher than that of the homopolymer type. Due to crystallization, the shrinkage rate of PP is quite high, generally 1.8~2.5%. And the direction uniformity of shrinkage is much better than PE-HD and other materials. Adding 30% glass additive can reduce shrinkage to 0.7%. Both homopolymer and copolymer PP materials have excellent moisture absorption resistance, acid and alkali corrosion resistance, and solubility resistance. However, it is not resistant to aromatic hydrocarbons (such as benzene) solvents, chlorinated hydrocarbons (carbon tetrachloride) solvents, etc., and the oxidation resistance of PP at high temperatures is not as good as that of PE.
Pure PP board
Low density, easy to weld and process, has excellent chemical resistance, heat resistance and impact resistance, non-toxic, tasteless, and is one of the most environmentally friendly boards at present. The main color is white, computer color, and other colors can also be customized according to customer requirements. Application range: acid and alkali resistant equipment.
Polypropylene (PP) extrusion sheet
The material is a plastic sheet made of PP resin as raw material, adding various functional additives, extruding, calendering, cooling, cutting and other processes.
Glass fiber reinforced PP board
Glass fiber reinforced PP board (FRPP board): After being reinforced with 20% glass fiber, in addition to maintaining the original excellent performance, the strength and stiffness are doubled compared with PP, and it has good heat resistance and low temperature resistance. Impact resistance, corrosion resistance and arc resistance, low shrinkage. Especially suitable for chemical fiber, chlor-alkali, petroleum, dyestuff, pesticide, food, medicine, light industry, metallurgy, sewage treatment and other fields.
β(β)-PPH single-sided non-woven sheet. (β)-PPH products have excellent thermal and oxygen aging resistance, long service life and good mechanical properties. It has been successfully applied to plate production, and the advanced technology is in a leading position in China. These products can be used in filter plates and spiral wound containers, FRP wound linings, storage, transportation and anti-corrosion systems in the petrochemical industry, water supply, water treatment and drainage systems for power plants and tap water. Plants; dust removal, cleaning, ventilation systems, etc. The length and width can be customized according to customer requirements, the board surface is smooth and flat, and the thickness is uniform.
PP extruded board has the characteristics of light weight, uniform thickness, smooth surface, good heat resistance, high mechanical strength, excellent chemical stability and electrical insulation, and non-toxic. PP board is widely used in chemical containers, machinery, electronics, electrical appliances, food packaging, medicine, decoration and water treatment and other fields. The practical temperature of PP board can reach 100 degrees.
Acid and alkali resistant equipment, electroplating equipment, solar photovoltaic equipment, environmental protection equipment, waste water, exhaust gas discharge equipment, scrubbers, clean rooms, semiconductor factories and related industrial equipment are also the preferred materials for manufacturing plastic water tanks, among which PP thick plates are widely used Used in perforated boards, punch mattresses, etc.
Recycling bins, including reusable recycling bins in various industries, vegetable and fruit packaging boxes, clothing storage boxes, stationery boxes;
Industrial boards, including the protection of the outer packaging of wires and cables, the protection of glass, steel plates, and the outer packaging of various items, gaskets, shelves, partitions, bottom plates, etc.;
Gone are the days of protecting building materials with cardboard and plywood. With the progress of the times and the improvement of taste, in order to ensure the integrity of the decoration design before it is completed and put into use, proper protection should be given to maintain operation. Economical, safe, convenient, and protection of building elevators and floors before acceptance.
Electronic industry protection. Conductive packaging products are mainly used for the packaging of electronic components such as IC wafers, IC packaging, testing, TFT-LCD, and optoelectronics. The purpose is to prevent other charged objects from contacting them, causing spark damage to parts due to electricity. In addition, there are conductive anti-static plastic plates, turnover boxes, etc. In addition to the above products, PP board can also be used for packaging of washing machine backboard, refrigerator insulation layer, frozen food, medicine, sugar and wine, etc. The hollow board production line can also be used to produce PE hollow boards to provide insulation partitions required for urban construction and rural areas.
