The difference between PVC and PU hose:
PVC and PU are very common materials for two kinds of production hose. PVC hose and PU hose are widely used in all walks of life. But there is a big difference in performance in these two hoses. The following are the most important points:
1. The temperature resistance range is different. The highest temperature resistance of the general PVC hose is 65 ° C, and the maximum temperature resistance of the PU hose can be 90 ° C.
2. Different abrasion resistance. The hose of PU material is more abrasion -resistant, so it is suitable for materials that are used to suck large and highly worn materials. In contrast, the wear resistance of the PVC hose is a bit weaker. It will shorten the service life.
3. The degree of hard and hard. PU and PVC materials are used to make steel wire hoses with the same wall thickness and steel wire spacing, and the PU material will softer, and the PVC will be relatively hard, unless the plasticizer in the PVC hose adds a lot. Plastic agents are a additive that makes PVC softened, but the current food standards have strict requirements on plasticizers. Therefore, the soft PVC and plasticizer content is far from meeting environmental protection requirements.
