Tire Rubber Melting Temperature

Pure rubber once vulcanised can not be melted or the tires on your car would melt under heavy braking.

Tire rubber melting temperature. 107 124 349 polyethylene hd. Tire temperatures are the easiest and most cost effective link you have to the action at the tire contact patch. Most modern shoe soles are not rubber as in natural latex based but are some form of plastic heat will melt most thermoform plastic but the problem will be making a suitable mould for the sole. At ambient temperature old tires can be turned into crumb rubber.

It will not melt. The rubber in tires is vulcanized meaning that is in fact one big molecule. The rubber used in creating tires is a mixture of many compounds including carbon latex rosin and chalk hardened by the addition of sulfur and other compounds. At low temperatures around 5 c to 6 c there is a risk that rubber hardens because of crystallization.

There is not a single melting point for these substances so using the term softening applies more closely to the super heating of rubber tires. A common method is to chop the tires into half inch pieces and mix the pieces with liquid nitrogen at a temperature of minus 148 degrees fahrenheit minus 100 degrees celsius. Rubber begins to melt at approximately 180 degrees celsius. Scientists have figured out that for every 10 degrees fahrenheit that the temperature rises the tire pressure will increase by one pound per square inch psi.

Using the tire temperatures effectively can pay considerable dividends on the race track and it s worth the effort to learn what they mean and how to adjust setups accordingly. The air pressure in tires increases as the temperature goes up. Melting points and ignition temperatures. 10 chassis tuning tricks using tire temperatures.

The optimum temperature for rubber is 20 c. 220 268 432 488 polyethylene ld. It doesn t sound like much but there s typically only 30 35 psi in the tires of passenger vehicles.
