Tire Rubber Melting Temperature

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.

Tire rubber melting temperature.

220 268 432 488 polyethylene ld. At low temperatures around 5 c to 6 c there is a risk that rubber hardens because of crystallization. Tire temperatures are the easiest and most cost effective link you have to the action at the tire contact patch. Total tire recycling using proprietary and patented process.

The air pressure in tires increases as the temperature goes up. Americans discard approximately 100 million tires every year which begs some type of recycling method to prevent overloading landfills. 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.

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. The rubber in tires is vulcanized meaning that is in fact one big molecule. Pure rubber once vulcanised can not be melted or the tires on your car would melt under heavy braking. 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.

The optimum temperature for rubber is 20 c. Rubber begins to melt at approximately 180 degrees celsius. Melting points and ignition temperatures. 107 124 349 polyethylene hd.

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. It doesn t sound like much but there s typically only 30 35 psi in the tires of passenger vehicles. When heated to a high enough temperature in an inert atmosphere away from air oxygen the rubber will decompose sometimes partially resulting in an oily ooze.
