Original Polyester Homopolymer R&D and Application

Polymer toughening modifier is a special additive added to plastics, rubber and other polymer materials, whose main function is to significantly improve the toughness, impact strength and anti-cracking properties of the base resin through physical or chemical action.

Multi-functional polyester homopolymer is a special powder material for plastics, rubber, asphalt and other polymers, which is custom developed by Rallychem Chemical in cooperation with the Japan Institute for Materials Research. Compared with traditional modification processing aids, Multi-functional polyester homopolymer is able to significantly improve the performance of the final product and bring more added value. It also increases the toughness of polymers and requires less additive volume to obtain the relevant functions, which is more cost-effective.
