Toughening and Modifying Technology of Automotive Polypropylene
　
Toughening modification technology of automotive polypropylene Toughening modification technology of automotive polypropylene Toughening modification technology of fully vulcanized polybutadiene nano-powder rubber developed independently toughening polypropylene, improving its impact resistance, providing toughening modification process method, providing technical guarantee for toughening automotive polypropylene; at the same time, it will get rid of long-term dependence of polyolefin elastomer Depending on the situation of import, we can realize the independent production of modified materials and open up high-tech export for the functional application of rubber (polybutadiene).
Toughening modification technology of automotive polypropylene using self-developed fully vulcanized polybutadiene nano-powder rubber toughens polypropylene, improves its impact resistance, provides toughening modification process method, provides technical guarantee for toughening automotive polypropylene; at the same time, it will also get rid of the long-term dependence on imports of polyolefin elastomers and realize modification. Materials are produced independently and high-tech exports are developed for functional applications of rubber (polybutadiene). Its main innovations are as follows: 1. less dosage, High Toughening efficiency and low modulus loss; 2. significantly improve its compatibility with crystalline polymers and inhibit phase separation; 3. stabilize the size of rubber phase microzone without vulcanization, simplify the blending process and reduce energy consumption; 4. realize the regulation of material mechanical properties, and continuously adjust the toughness of materials. The modification technology is simple and feasible, especially suitable for the design and development of different mechanical properties materials.
