It is well known that no vulcanized rubber can fully rebound; there will always be some degree of damping, either large or small. This damping or viscosity property will reduce the resilience of the vulcanized rubber and increase hysteresis or heat generation during periodic deformation. Generally, the better the resilience of the rubber compound, the lower the hysteresis. However, sometimes, due to differences in temperature or deformation rate, such a completely opposite relationship does not always exist.
Blister defects in rubber products are a frequent problem in factories and cost many companies millions of dollars each year.
The curing speed of the rubber is a very important characteristic parameter.The speed of curing directly determines the time it takes for the rubber product to be removed from the mold, and the shorter the time spent in the mold, the lower the cost of production.
Poor dispersion of carbon black will lead to a decrease in the physical properties of the vulcanised compound and deterioration of the product properties, such as non-abrasion resistance.
Bridgestone, a global leader in premium tyres and sustainable mobility solutions, has revealed plans to invest in a new driver-in-the-loop (DiL) simulator at its EMEA R&D Centre, which is located close to Rome, Italy. The company's dedication to completely digitising the tyre development process is demonstrated by the new, cutting-edge DiL simulator, which enhances its Virtual tire Development (VTD) capabilities.
