Extreme HG
Extreme™ HG is a high gloss, high performance, thermoplastic olefin (TPO) structure engineered for improved thermoforming characteristics. Extreme™ HG provides a wide processing range, enabling consistent, controlled sag sheet for stable thermoforming. For OEMs, Extreme™ HG provides excellent cold crack resistance, outstanding chemical resistance, a high gloss molded-in-color surface. Along with the improved processing window, Extreme™ HG provides the most cost effective TPO in the marketplace for large part thermoforming applications.
Features and Benefits
- High gloss cap surface
- Tough, high impact TPO structure
- Integral UV-protective packages for cap and substrate
- Wide thermoforming processing window
- Resilient to high vibration application
- Low CLTE for dimensional stability

Processing
Extreme™ HG can be thermoformed in standard thermoforming ovens, although zoned ceramic or quartz heaters are recommended. Forming over temperature-controlled aluminum tooling results in the best part aesthetics. Molds made from fiberglass or epoxy, can be used for tooling prototyping or small part runs. Care must be taken in forming to heat sheet evenly and not overheat. Stock temperatures of approximately 340°F – 360 °F are recommended targets, but each process should be adjusted to allow proper forming. As with any thermoplastic material, coefficient of thermal expansion and mold shrinkage should be considered for proper part fit and tooling design.
