When it comes to car bumpers, the first reaction of many people may be that car bumpers are designed to allow vehicles to absorb energy during a collision and better protect the car. But why use a plastic bumper? In fact, there are many unknown secrets. 汽车保险杠专用料 --高刚性PP材料 。 Next Xiaobian takes everyone to understand: special materials for automotive bumpers -high rigid PP material .
PP材料性能上的不足，国内外都进行了大量的PP料增韧改性研究，在多相共聚和共混改性方面取得了突破性的进展，共混改性简单易行备受青睐。 In order to improve the performance of PP materials, a lot of researches on toughening and modification of PP materials have been carried out at home and abroad. Breakthrough progress has been made in multiphase copolymerization and blending modification. Favor.
(EPDM)对PP有良好的增韧效果，该专用料无论在常温还是低温条件下均具有优异的抗冲击性能，而且具有优异的耐老化性能、良好的加工性能和涂装性能，在汽车保险杠材料方面获得了广泛应用。 Among them, EPDM has a good toughening effect on PP. This special material has excellent impact resistance at normal temperature or low temperature, and has excellent aging resistance, good processing performance and coating. The mounting performance has been widely used in automotive bumper materials. However, with the advent of POE, it has unique and excellent properties, and quickly replaced EPDM as the main toughener for the production of PP bumpers. Therefore, POE toughened PP can be used to prepare high rigid PP bumper materials.
A big reason why the bumper uses modified plastic is that its main responsibility is to protect pedestrians.
PP材料保险杠能够缓解对行人腿部，尤其是小腿的撞击力，配合前杠的合理设计，降低行人被撞时的伤害程度。 Because in the traffic environment, pedestrians are a vulnerable group. When a vehicle collides, a high-rigidity PP material bumper can alleviate the impact on pedestrians' legs, especially the lower legs. In conjunction with the rational design of the front bumper, it reduces the collision of pedestrians. The degree of damage at the time. This high-toughness soft plastic is more flexible than metal and better absorbs impact.
