BORISE Step Seal: PUAR is a new product with intellectual property rights independently developed by Borise. It’s a new polymer material as substitute of traditional step seal of PTFE+Cu powder, with the tear resistance and super wear-resisting property that traditional material doesn’t have. The step seal made of PUAR material is twice the service life of the traditional one, and has a wider range of application conditions.

The PPDI polyurethane material developed by Borise features excellent resilience, wear resistance and fatigue resistance. In addition, it possesses low interior heat generation and excellent dynamic performance, which permits its operation in working conditions of high frequency and high-low temperature (-30∽130°C) where ordinary polyurethane materials cannot resist, especially adaptable to the working environments of breaking hammers of high-frequency and high-temperature.
