Brief introduction of pp sheet plastic board
Polypropylene (PP) extruded sheet is a plastic sheet made of PP resin with various functional additives, which is extruded, calendered, cooled and cut. PP board is a semi-crystalline material. It is harder and has a higher melting point than PE. Because homopolymer PP is very brittle above 0℃, many commercial PP materials are random polymers with ethylene content of 1~4% or sandwich polymers with higher ethylene content. * * * Polymer-based PP material has low thermal deformation temperature (100℃), low transparency, low gloss and low rigidity, but strong impact strength.
Characteristics of pp sheet and plastic board
The strength of polypropylene increases with the increase of ethylene content. The Vicat softening temperature of polypropylene is 65438 050℃. Because of its high crystallinity, this material has good surface hardness and scratch resistance. PP has no problem of environmental stress cracking, and it is usually modified by adding glass fiber, metal additives or thermoplastic rubber. The range of MFR of PP is 1~40. PP with low MFR has better impact resistance, but lower tensile strength. For materials with the same MFR, the strength of polymer type is higher than that of homopolymer type. Due to crystallization, the shrinkage of PP is quite high, generally 1.8~2.5%. And the directional uniformity of shrinkage is much better than that of PE-HD and other materials. Adding 30% glass additive can reduce the shrinkage to 0.7%. Both homopolymer and polymer PP materials have excellent moisture absorption resistance, acid and alkali corrosion resistance and solubility resistance. But it is not resistant to aromatic hydrocarbon (such as benzene) solvents and chlorinated hydrocarbon (carbon tetrachloride) solvents. The oxidation resistance of PP at high temperature is not as good as that of PE.
Application scope of pp sheet plastic board
Acid and alkali resistant equipment, environmental protection equipment, waste water and waste gas discharge equipment, washing tower, clean room, semiconductor factory and related industries are also the first choice materials for manufacturing plastic water tanks, among which PP thick plates are widely used in punching plates and pads.
The price of pp board and plastic board
The price of pp plastic board ranges from 2.6 yuan to 18 yuan/kg. (Price source network, for reference only. )
In the above article, Bian Xiao introduced where pp sheet and plastic board are suitable for use, what is the price of pp sheet and plastic board, and what are the characteristics of pp sheet and plastic board. Knowing the characteristics of pp sheet and plastic board, we can use pp sheet and plastic board more easily and give full play to their advantages. The use of pp board and plastic board in environmental protection equipment is very large, and environmental protection is the general trend, so the value of pp board and plastic board is very promising.
