Toughened plastic is a kind of plastic alloy which starts from the design of polymer molecules and combines with polymer * * * mixed modification technology to construct a fine micro-phase structure, thus achieving a sudden change in macro-properties. Shanghai Jinhu Rili Plastic Co., Ltd., a subsidiary of Shanghai Rizhisheng New Technology Development Co., Ltd., has been successfully developed. It can be used in the field where high safety is required when materials are impacted at high speed. Such as automobile interior and exterior decoration, sports equipment, sports protective gear and other products.
toughened plastic is a kind of plastic that shows its strength and rigidity when it is static or subjected to low-speed impact, but shows rubber-like ductility and energy absorption when it is subjected to high-speed impact, so it is not easy to brittle failure. Tempered plastics have the following characteristics:
1. When static or subjected to low-speed impact, it reflects the strength and rigidity of ordinary engineering plastics; When subjected to high-speed impact, it shows the same ductility and toughness as rubber, thus playing the role of energy absorption and protection. However, when ordinary toughened plastics are subjected to high-speed impact force, a large number of cracks will initiate and propagate, reflecting brittle failure.
2. Even when the material is damaged by external force, the damaged part shows ductile damage, instead of brittle damage such as acute angle and scattered fragments.
