Problems solved by technology

But at the same time, there are also the following disadvantages: ①The fluidity is too high at high temperature, and it is difficult to inject resin alone; ②The cost is high, and the price is twice as high as that of general engineering plastics; ③The impact strength is poor, the product is brittle, and the welding strength is not Good; ④ Due to its excellent chemical resistance, its coating and coloring properties are not ideal, so it is necessary to modify
However, the above-mentioned patent does not add a toughening agent, and the impact strength of the resulting PPS/PPO alloy is limited. If it is used in safety-related fields, such as battery packs for electric vehicles, poor impact strength will easily lead to cracking of the battery pack after impact, electrolysis Liquid leakag
