What is the use of PET recycled pellets

a. Re-manufacture of PET bottles. Recycled pellets cannot be used in direct contact with food, but can be used in the middle layer of three-layer PET bottles to make carbonated beverage bottles.

b. Spinning to make fibers. Recycled PET materials can be used to spin into fibers for pillow cores, mattresses, sleeping bags, felts, etc.

c. Glass fiber reinforced material. Recycled PET reinforced with glass fiber has good heat resistance and mechanical strength. It can be used to make auto parts, such as heat-resistant car wheel covers, and its thermal distortion temperature can reach 240 degrees. The flexural modulus of elasticity is 9500MPa, the bending strength is 214 MPa, and the impact strength is 15kf/m2.

d. Blending modification. Recycled PET materials can be blended with other polymers to prepare various modified materials. For example, blending with PE can obtain PET blends with improved impact performance. PE: PET is (10 ~50): (90~50): If a small amount of polypropylene is added, the dimensional stability of the blend can be significantly improved. Because the polarity of PE and PET is quite different, it is necessary to carry out compatibility treatment during blending, and the compatibility is generally improved by grafting modification of polyolefin.
