Into carbonated cosmetic bottles. , Spinning to make fibers, regenerated pet materials can be used to spin into fibers, used as sleeping bags, mattresses, pillow cores, felts, etc. , Glass fiber reinforced material, recycled pet reinforced by glass fiber has good heat resistance and mechanical strength, and can be used to make auto parts, such as heat-resistant car wheel covers.

, Blending modification, recycled pet materials can be blended with other polymers to produce various modified materials, such as blending with pe, you can get pet blends with improved impact performance; if you add a little more The dimensional stability of polypropylene and blends can be significantly improved. Because the polarity of pe and pet are quite different, compatibility treatment is required when blending, generally by grafting modification of polyolefin to improve compatibility. Discarded pet plastic bottles are processed and reprocessed. In addition to re-making pet plastic bottles, they can also be used to make sleeping bags, pillow cores, car wheel covers, etc. The consumption of pet plastic bottles in my country is very high.
