PPT-POLYMERS

Poly means MANY and MER means repeating unit Polymers are macromolecules formed by joining of repeating structural units on a large scale The repeating structural units are called . These polymers bring a signi64257cant contribution to the sustainable development in view of the wider range of disposal options with minor environmental impact As a result the market of these environmentally friendly materials is in rapid expansion performance polymers to improve the impact strength and aesthetic appearance of its polypropylene (PP) injection molded paint pails. Vistamaxx polymers also deliver better processability and cost per Kyle Douglas, James Farber, Steven Flynn, Janie Gu, . Vivian Qin, Jenny Shih, Jake . Silberg. , Anita . Wamakima.
