  Polypropylene also includes a copolymer of propylene and a small amount of ethylene. It's the lightest general-purpose plastic. Corrosion resistance, tensile strength 30MPa, strength, rigidity and transparency are better than polyethylene. The disadvantage is poor impact resistance at low temperature and easy aging, but can be overcome by modification and addition of antioxidant. Brittle temperature - 35 ℃, 35 ℃ below - will happen embrittlement, cold tolerance than polyethylene. The chemical stability of polypropylene is very good, except can be eroded by concentrated sulfuric acid and concentrated nitric acid, it is stable to all kinds of chemical reagents.
