Polypropylene - PP 3902300090
Polypropylene (PP) - Unlike polyethylene, polypropylene is less dense (density 0.90 g / cm3, which is the lowest value in general for all plastics), more solid (resistant to abrasion ), more heat resistant (begins to soften at 140 ° C, melting point 175 ° C), almost does not undergo stress corrosion cracking. It has a high sensitivity to light and oxygen (sensitivity decreases when stabilizers are introduced).
