/ tyre applications
GRP’s Rubber plays a vital role in enhancing the performance and sustainability of tyre manufacturing. Derived from end-of-life tyres and processed to meet stringent quality standards, our reclaim rubber improves compound flexibility, reduces production costs, and supports eco-friendly formulations. +More
The inner liner is a rubber compound bonded to the inside of the cord body that retains air under pressure. It has no cord reinforcing and function as an inner tube in a tubeless tire
It is extruded Butyl or Halobutyl rubber sheet compounded with rubber additives. A key property of inner liner is low air permeability as it functions as inner tube.
A typical Inner Liner formulation contains a Butyl Rubber / Halobutyl Rubber and Reclaim Rubber.
Inner liner compounds are formulated to minimize permeation of air through the tire carcass. Compound properties and gauges (thickness) as well as the temperature and inflation pressureimpact on the permeation rate.
BUTYL RECLAIM
CHLOROBUTYL RECLAIM
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 Consumption
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 or Chlorobutyl Rubber and Butyl/ Chlorobutyl Reclaim Rubber.

The sidewall is the area of a tire from the bead to the tread. It forms a protective covering for the cord body.
Sidewall rubber compounds resist aging, cracking, cutting, and snagging.Tire sidewall rubber serves to protect the body plies from abrasion, impact and flex fatigue. The rubber compound is formulated to resist cracking due to environmental hazards such as ozone, oxygen, UV radiation and heat.
The sidewalls also carry decorative treatments, sometimes including white or colored stripes or letters.
A typical sidewall formulation contains a blend of Natural Rubber, Butadiene Rubber and Reclaim Rubber.

The body is made up of several layers of different fabrics coated with Rubber called plies. Rubber coated cord, called body plies, make up the cord body. The cord body provides tyre strength and transmits cornering forces from the tread to the wheel. Belt plies are two or more strong layers of cord under the tread area. The cap ply also found in some tires is similar to belt edge strips only full width instead of just on the belt edges.
In textile reinforcements of nylon, polyester, rayon, aramid, etc., individual filaments are twisted and cabled together to form cords.
A typical Inner Liner formulation contains a Natural Rubber and Reclaim Rubber.

The tread is the portion of the tyre in contact with the road surface.
Tyre tread shape, grooves (pattern) and compound are designed to optimize the wear, traction, handling, fuel economy, and cut resistance characteristics of the tyre.
A typical tread formulation contains a blend of Natural Rubber,Styrene Butadiene Rubber and Reclaim Rubber.
