HB236 inorganic sprayed rockwool mineral reinforced fiber for break pads and linings

Short Description:

HB236 mineral fiber is designed for sealing materials. Its is longer than other mineral fibre models used in the friction application. It has properties like low slag ball content,, good divisibility, high temperature resistant and excellent aspect ratio, and is suitable for the production and application of various non-asbestos friction materials and sealing materials.

Rock wool fiber HB236 is made of basalt, diabase and dolomite by blowing or centrifugation at high temperature. After being fixed on length and being removed on slag ball, the mineral fiber HB236 is finished.

HB236 rock wool mineral fibers are suitable for industrial structural reinforcements such as friction, sealing, road engineering, coatings, but it is individually designed for sealing materials. 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.
