Polypropylene (pp) has good plasticity, solubility and toughness. ABS resin is a slightly yellow solid with certain toughness. It has strong corrosion resistance to acids, alkalis and salts, and can also tolerate dissolution by organic solvents to a certain extent. The advantages of ABS resin are impact resistance, sound insulation and scratch resistance.
Railway cover mould belongs to the mould for processing and manufacturing concrete and cement prefabricated parts, and is one of the cover moulds.
Railway cover mould has the advantages of convenient mould assembly and disassembly, stable mould assembly, no slurry leakage, stable size and good quality of the railway cover mould produced.
Polypropylene PP raw materials are used. PP is a thermoplastic resin made by propylene polymerization. It is a semi-crystalline material. It is harder and has a higher melting point than PE. Polypropylene (pp) has good plasticity, solubility and toughness.
ABS resin is a slightly yellow solid with a certain toughness. It is resistant to acid, alkali and salt corrosion and can also tolerate dissolution by organic solvents to a certain extent. ABS resin has good formability, and the surface of the processed products is smooth and easy to dye and electroplate. The advantages of ABS resin are impact resistance, sound insulation and scratch resistance. It has better heat resistance.
