By K S Nayar: At an international tyre industry exhibition, a rubber technologist with a major tyre manufacturer told me about the culture of secrecy surrounding product development. Even the CEO is barred from visiting the smelly rubber compounding section unless he gets in-house security clearance. The chief compounder and R&D head are provided with 24/7 security. The scene evoked images of Fort Knox, the US Bullion Depository Building. I admit It is a hyperbole of exaggerated security at top tyre companies. But there is no denying the fact that tyre makers jealously guard their compounding formulae and tyre...

Papa Don’t Preach… Engage

Having worked on spreading awareness on tyre safety for years as a part of collective good corporate citizenry of tyre industry in India, it is gratifying to note that world at large is taking notice. People and organizations are reaching out to ATMA for campaigns on tyre safety or are reciprocating actively to such proposals made, a far cry from the days of yore when tyre safety as a concept was considered alien. After successful campaigns at different campuses of Infosys Technologies, Honda Cars and India Rubber Expo in the year gone by, more organizations are coming forward. What...

Tyre Geometry Measurement at highest level

Tyre uniformity grading is standard practice today and machines are available to measure and grade 100% of tyres in production. Mass and stiffness variations on a tyre circumference cause radial and lateral force deviations which can be measured and graded. The geometrical inspection of a tyre is now also becoming an important test and a run-out analyses is being increasingly recommended by many of the known OEMs. Radial and lateral run-out is the geometric variations in the tyre tread and sidewalls with respect to the nominal values. Test systems made by inmess offer a wide variety of testing procedures...

Finding the Right Compound

By TA News Bureau: As rubber and tyre technologists race to discover the perfect rubber compound to make fuel-saving green tyre formulations, Dr Siti Salina Sarkawi is quietly working in her lab to find the most eco-friendly substance to achieve this goal. She is presently the programme head of ‘Silica Dispersion Technology for Green Tyres’ under Technology & Engineering Division of the Malaysian Rubber Board. Her current projects are Application of Ekoprena for Environmentally Friendly Retreaded Tyres and Passenger Car Tyres. In an interview to Tyre Asia, the research scientist whose expertise includes silica technology, green tyre, epoxidized natural...
