Purenit ® is resistant to chemicals, can be combined and glued with other materials. It is resistant to high temperatures, moisture, without thickness swelling and cracking, with high compressive strength and excellent insulating properties.
The main advantages of purenit
- Purenit is a health-friendly duroplastic material on a polyurethane base made of hard foam with heat resistance from -50 °C to +110 °C, while it can withstand up to +240 °C for a short time.
- Purenit has a high compressive strength = possibility of mounting HST portals directly on PURENIT.
- Purenit is waterproof, not susceptible to moisture.
