Application of Liquid Polybutadienes in Sidewall of All-steel Giant Off-The-Road Radial Tire
The application of liquid polybutadiene rubber(LPB)in the sidewall compound of all-steel giant off-the-road radial tires was studied.The results showed that using LPB instead of the same level of tackifying resin in the sidewall compound of giant off-the-road radial tires,the processing safety performance of the compound was improved,the vulcanization rate was reduced,the heat build-up of the vulcanization was reduced,the physical property and aging resistance property were increased.The overall performance of the sidewall compound was improved.
