High clarity resin for I/M applications

LyondellBasell’s new RM2073 resin has been developed to provide high clarity as a cost-effective alternative to polycarbonate (PC) in injection molding applications. It is also well suited as a substitute for glass or for other amorphous, transparent polymers, such as polymethyl-methacrylate or styrene acrylonitrile.

In addition to the transparency improvements, the high melt flow of RM2073 offers excellent shear-thinning behavior, which can mean improved output for molders. The flow characteristics present opportunities for reducing wall thickness or part density. Significant improvements in chemical resistance can also be achieved.

This grade exhibits superior environmental stress crack resistance when compared to PC. RM2073 also requires lower processing temperatures compared to PC, which could translate into lower energy costs for the injection molders and better overall economics. Its added rigidity makes it well suited for applications that require strength as well as thin walls.


The RM2073 resin can be used in a wide range of injection molded applications, including food and beverage packaging, foodservice trays/covers, drinking cups/pitchers, storage containers, CD/DVD cases and technical products.
