Extreme Plus HG® and Extreme Plus LG® sheet are both high performance thermoplastic polyolefin (TPO) structures. With a wide processing range, they are specifically engineered for easy, consistent, and stable thermoforming.

Extreme Plus HG® is our high gloss sheet, while Extreme Plus LG® offers the same performance properties with the option of a lower gloss finish. These tough, high impact TPO sheets provide excellent cold crack resistance and outstanding chemical resistance. A high or low gloss, molded-in-color surface can be achieved on many applications where harsh weather, chemicals, heavy vibration or heat stresses are factors.
