The difference between material PP and PC is: different nature, different flame retardant, different applications.
One, the nature of different
1, PP: is a polymer made of propylene polymerization reaction.
2, PC: the molecular chain contains carbonate ester-based polymer, according to the structure of the ester group can be divided into aliphatic, aromatic, aliphatic-aromatic and other types.
Two, different flame retardant
1, PP: flammable, melting point of 165 ℃, soften at about 155 ℃ .
2, PC: heat-resistant, impact resistance, flame retardant BI level, in the ordinary use of temperature have good mechanical properties.
Three, different applications
1, PP: widely used in clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts, conveying pipelines, chemical containers, and other production, but also used for food, pharmaceutical packaging.
2, PC: used in the glass assembly industry, automotive industry and electronics, electrical industry, followed by industrial machinery parts, optical disks, packaging, computers and other office equipment, medical and health care, film, leisure and protective equipment.
