It is harder and has a higher melting point than PE. Since the PP temperature of the homopolymer type is very brittle when it is higher than 0 \u00b0 C, many commercial <strong><a href=\"https:\/\/www.recycle-plant.com\/vi\/plastic-film-recycling-production-line\/\" data-type=\"link\" data-id=\"https:\/\/www.recycle-plant.com\/plastic-film-recycling-production-line\/\">PP materials<\/a><\/strong> are random copolymers of 1 to 4% ethylene or a clamp copolymer of a higher ratio of ethylene. The copolymer type PP material has a low heat distortion temperature (100 \u00b0 C), low transparency, low gloss, low rigidity, but has a stronger impact strength. <\/p>    <p class=\"wp-block-paragraph\">The strength of PP increases as the ethylene content increases. The Vicat softening temperature of PP is 150 \u00b0C. Due to the high degree of crystallinity, this material has excellent surface stiffness and scratch resistance. There is no environmental stress cracking problem in PP. The PP is usually modified by adding glass fibers, metal additives or thermoplastic rubber.<\/p>    <p class=\"wp-block-paragraph\">T\u1ed1c \u0111\u1ed9 d\u00f2ng ch\u1ea3y c\u1ee7a PP c\u00f3 ch\u1ec9 s\u1ed1 MFR dao \u0111\u1ed9ng t\u1eeb 1 \u0111\u1ebfn 40.
