PTR- Precured Tread Rubber

Pre-cured tread rubber(PTR) is a vulcanized rubber belt molded in a particular design pattern with a specified width, thickness & weight, suitable to perform on a given road application such as long-haul, short-haul, hilly terrains, and mines.

PTR rubber has two key aspects to it, first is the chemical composition of rubber compound and second is the design pattern. The chemical composition of a mine tread rubber is very different from that of hills, similarly the design pattern for short-haul might vary from the design pattern for a long-haul application. It is of paramount importance to understand the vehicle application before choosing the right tread, the right choice takes into consideration the type of vehicle, tyre axle, tyre type and road application.

• Provides protection to tyre buffed surface from oxidation.
• Provide excellent green tack
• Good cured bonding between casing and cushion

AVAILABLE IN THREE VARIANTS

• Ready to use- (10 - 11 % solid)
• Ready to use- (7 - 8 % solids)
• Radial cement- (extra bonding strength with steel wires)

ENVELOPE

Indag Full Skirt Envelopes

An envelope is made of a thin gauge rubber sheet to cover the tyre casing before putting it in a chamber for curing in the retreading process. This is used for protecting the tyre casing from direct contact with hot air and provide uniform pressure all around on the tyre casing. We at Indag, along with our R&D Team have successfully developed envelopes that provide the lowest Cost-per-Cure in the industry.
