Inner tubes are torus-shaped balloons made from an impermeable material, such as Butyl Rubber or Chlorobutyl Rubber. The inner tubes are inserted into the tire and inflated to retain air pressure.
Auto tubes are manufactured by molding method. Mixed compounded rubber is fed into the extruder and the rubber compound takes the shape of
long tubes then proper length of this green tube is cut and tube valve is fitted in this green tube and the end of the tubes are jointed by means of butt joining machine. This green tube is vulcanized in the mould having air pressure inside.
A typical Inner Tube formulation contains a Butyl Rubber / Halobutyl Rubber and Butyl/ Chlorobutyl Reclaim Rubber.
Compared to other grades of Reclaimed Rubber there is low air permeability
Less masticating with easy incorporation
Improved Extrusion Quality & Rate with better control on Dimensions
Good tack in compound
Reduction in splicing defects
Reduced Power ConsumptionNote: For suitable formulations, please contact us. We will help you with your specific requirements and provide recommended.
