Sailun Tire announced an increase in investment in its Indonesian production base project, raising the total investment to 299.74 million US dollars, greatly increasing the production capacity of semi-steel radial tires, laying out the overseas market by virtue of Indonesian resources. The project is expected to achieve an annual net profit of 62.55 million US dollars, helping to improve the global production capacity matrix.
On July 14, Sailun Tire (601058.SH) issued an announcement, announcing that its wholly-owned subsidiary Sailun (Shenyang) Tire Co., Ltd. (referred to as "Sailun Shenyang") will acquire 100% of the equity of Bridgestone (Shenyang) Tire Co., Ltd. (referred to as "Bridgestone Shenyang") held by Bridgestone (China) Investment Co., Ltd. for 265 million yuan.
DFTMC, a specialized trader of quality pre-owned rubber machinery, presents an exceptional opportunity: A fully operational PCR (Radial Passenger Car) tire manufacturing plant with an annual capacity of 6 million units is now available for immediate acquisition.
1. Why should rubber be plasticized? 2. What factors affect the plasticization of rubber in an internal mixer? 。。。。。。
On June 5, 2025, ZC Rubber, the "domestic number one tire company", officially landed on the main board of the Shanghai Stock Exchange with an opening price of 57.00 yuan, up 22.58%. The increase subsequently narrowed and the total market value at the opening was close to 50 billion yuan.
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.
