Automobile tubes from pondy polymers, sold under the brand name robex, are made of high-quality butyl rubber, and the compound is specially for-mulated to withstand heat. Therefore, it can transport loads for longer distance on tough roads, under varying weather conditions. In addition, air loss is negligible and punctures are limited. Butyl rubber provides better air retention and reduces the risk of blowouts after punc-tures, thereby ensuring longer tyre life. Robex automobile tubes cover various grades such as: chloro butyl tubes and butyl tubes. Robex tubes, due to their superior compound and process controls, provide better heat resistance, and can withstand flex deformation of tyres. In addition, better ozone-ageing resistance extends storage life.
