Rubbers Based on Blends of Propylene Oxide and Ultrafine Polytetrafluoroethylene
Results of the development of sealing rubbers based on blends of propylene oxide (PO) and ultrafine polytetrafluoroethylene (UPTFE) for North appliances are presented. Positive effect on the material properties is achieved at addition of 0.5 - 1,0 parts by weight of UPTFE per 100 parts by weight of PO. This is due to the high activity of particles UPTFE, their nanostructure organization and uniformity of their distribution in the elastomer matrix. RF patent is received on the formulation of rubber.
