PP sheet, also known as polypropylene plastic sheet, is a semi-crystalline material. PP sheet has the characteristics of light weight, uniform thickness, smooth surface, good heat resistance, high mechanical strength, excellent chemical stability, electrical insulation and non-toxicity. The shrinkage rate of the PP board is quite high. Since the PP sheet is a semi-crystalline material, the shrinkage rate is generally 1.8 to 2.5%. And the direction uniformity of shrinkage is much better than materials such as PE-HD. PP sheet has excellent moisture absorption resistance, acid and alkali corrosion resistance and solubility resistance. PP plate color is generally green, porcelain white, milky white, translucent, beige gray, you can also order other colors. Please follow the Jiuzhi Plastics Network to find out the types and applications of PP sheets, as follows:
Type of PP sheet
1. Pure PP board: Pure PP board has low density, easy welding and processing, and has excellent chemical resistance, heat resistance and impact resistance, non-toxicity and odorlessness. It is one of the most suitable engineering plastics for environmental protection. The main colors are white, micro-machine color, other colors can also be customized according to customer requirements. Applications: Acid and alkali resistant equipment, environmentally friendly equipment, waste water, exhaust gas discharge equipment, washing towers, clean rooms, semiconductor plants and related industrial equipment, is also the material of choice for the manufacture of plastic water tanks, of which PP thick sheets are widely used for stamping Board, punching mattress board, etc.
2. Polypropylene (PP) extruded sheet: It is a plastic sheet made by adding PP resin into various functional additives through extrusion, calendering, cooling, cutting and other processes.
3. Glass fiber reinforced PP board: Glass fiber reinforced PP board (FRPP board): After being reinforced by glass fiber by 20%, in addition to maintaining the original excellent performance, the strength and rigidity are doubled compared with PP, and it is good. Heat resistance, low temperature impact resistance, anti-corrosion and arc resistance, low shrinkage. Especially suitable for chemical fiber, petroleum, dyes, pesticides, food, medicine, light industry, metallurgy, sewage treatment and other fields.
PP sheet application
PP sheet is widely used in acid and alkali equipment, electroplating equipment, solar photovoltaic equipment, environmental protection equipment, waste water, exhaust gas discharge equipment, washing towers, clean rooms, semiconductor plants and related industrial equipment, as well as plastic water tanks. The preferred material, in which PP thick plates are widely used in stamping plates, punching mattresses and so on.
