It is obtained from the action of heating, pressurization, and catalysts under the action of heating, pressurization and catalyst, and the ethylene monomers are randomly distributed in the long chain of acrylic. The random addition of ethylene reducing the crystallization and melting point of the polymer, improving the impact of materials, long -term static water pressure, long -term heat -resistant oxygen, and pipe processing molding.

PP-R molecular chain structure, ethylene monomer content and other indicators have a direct impact on the long-term thermal stability, mechanical performance and processing performance of the material. The more irregularly the distribution of ethylene monomers in the acrylic molecular chain, the more significant changes in the performance of polypropylene.

1.Advantages: good comprehensive performance, high strength, high rigidity, good thermal resistance, good size stability, excellent low temperature toughness (good deflection), good transparency, good gloss.

2.Disadvantages: The best performance in PP.

3.Uses: thin film level, injection molding. Pipes, contraction films, drops, high transparent containers, transparent family supplies, disposable syringe, packaging paper film.

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