1. RUBBER COMPOUND

Synthetic and Natural rubber, Carbon Black and Chemicals are taken as per formulation and mixed in a Banbury for a specified time and aged for 24 hours.  Vulcanizing agents are added and the Master Batch is mixed in the Banbury again. This Compound is tested for viscosity on a Mooney Viscometer.  Thermal properties are tested on an Oscillating Disc Rheometer; Physical Properties on Universal Tensile Testing Machine and Abrasion resistance is determined on DIN Abrader.

 

 

2. PRE CURED TREAD RUBBER

 

ProcessThe Laboratory tested and approved compound is extruded to required sizes for pressing to form the Pre-cured Tread Rubber. The Extruded Rubber Strip is pressed under high pressure and temperature. The Pre-Cured Rubber Strips are buffed to international RMA Standards of Buff Texture. Treads thus prepared treads are packed in stretch wrap poly.

 

 

3. CUSHION GUM

 

The required compound for cushion gum is calendared on roller drums to maintain the thickness and passed through cooling drums to obtain best properties. The scorch properties are tested with the help of Rheometer on 100% of production.

 

 

4. VULCANIZING SOLUTION

 

The specified compound is mixed with solvent and stirred for the needed duration to obtain a thoroughly mixed and homogenized liquid, which is used in retreading to avoid oxidation and provide tackiness for the buffed tire. Vulcanizing Solution is manufactured suitably for brush as well as spray applications.
