The high ethylene content is high, generally 7-15%, but because the probability of two ethylene monomers and three monomers in PP-B is very high, it shows that because the ethylene monomer has only an embedded paragraph, it is not mounted that it will not be in the embedded paragraph, and it is not mounted that it will not be in the embedded paragraph and it will not be no. The regularity of PP-H is reduced, so it does not achieve the purpose of improving PP-H melting point, long-term static water pressure, long-term heat-resistant oxygen aging, and pipe processing molding.

1.Advantages: A better resistance to impact, and a certain degree of rigidity improves the shortcomings of impact strength: low transparency, low luster.

2.Disadvantages: anti -humidity, acid -alkali corrosion, anti -soluble, poor antioxidant resistance at high temperature.

3.Uses: Pure levels, injection molding levels. Insurance rods, thin -walled products, strollers, sports equipment, luggage, paint barrels, battery boxes, thin -walled products

4.Distinguishing method: After litting, not black, it can pull out a long round silk
