Sealing materials made of our mineral fibers have excellent properties, such as high fibre index , high temperature and pressure, performance improved compression set and creep resistance, improved mechanical strength, prolonged gasket life and recyclability. PRODUCTS FEATURES To meet different needs, HB236 was designed with longer length. Generally it is used for sealing materials. Its properties show as below: ● Non asbestos Degradable and pollution-free, and no asbestos. ● Excellent stability We developed precise formula with stable chemical composition to ensure quality from the source. ● Low shot content Independent purification process of shot removal to improve fiber purity. HB236 has go through 9 times slag removal. ● Stable aspect ratio Through advanced chopped cutting process and digital control, we uniform fiber length distribution. ● Excellent dispersion Rock wool fiber HB236 has good dispersibility and is suitable for mixing with various mixers. The brake lining products produced with it have no cotton particles on the grinding surface, and the product has a uniform appearance and good texture. ● Good structure reinforcement effect Mineral fiber has a good aspect ratio to make it perfect on structure reinforcing function. High temperature resistant, corrosion resistance, moisture resistance and wear resistance.
