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. Due to the brittleness of homopolymer type PP at temperatures above 0 ℃, many commercial PP materials are irregular copolymers with 1-4% ethylene added or clamp copolymers with higher ethylene content.
PP extruded sheet has the characteristics of light weight, uniform thickness, smooth and flat surface, good heat resistance, high mechanical strength, excellent chemical stability and electrical insulation, and non toxicity. PP board is widely used in fields such as chemical containers, machinery, electronics, electrical appliances, food packaging, medicine, decoration, and water treatment. The practical temperature of PP board can reach 100 degrees.
Acid and alkali resistant equipment, electroplating equipment, solar photovoltaic equipment, environmental protection equipment, wastewater and exhaust gas discharge equipment, washing towers, clean rooms, semiconductor factories and related industrial equipment, are also the preferred materials for manufacturing plastic water tanks. PP thick sheet is widely used in stamping plates, punch press pads, etc.
The commonly used colors for PP board are natural color, beige (beige), green, blue, porcelain white, milky white, semi transparent, etc.
