The global natural rubber production area has begun to transition from high-yield to low-yield, and the expectation of seasonal reduction has boosted the rubber market. As of January, domestic natural rubber production areas in Yunnan and Hainan have been completely shut down. Due to the reduction in the supply of raw material glue, the purchase price of the rubber factory
According to ANRPC’s latest report, as of the end of September, global natural rubber production increased by 1.5% to 1.779 million tons. Among them, Vietnam and India fell by 9.8% and 14.1% respectively, which was mainly due to weather. From January to September, global natural rubber consumption increased by 6.6% year-on-year to 10.653 million tons, of which China, India, Thailand
Common high-temperature cables are wrapped with a layer of “rubber protective layer”. When such a protective layer is destroyed, the inside of the high-temperature cable will be damaged and cannot be used anymore, so the manufacturer will prevent the outer rubber protective layer from aging. Treatment, this process involves the anti-aging agent. 1.Due to the different characteristics of each type
The main component of organic silicon defoamer is called silicon oil silicone component, silicone oil at room temperature is not volatile oily liquid, in water, animal and vegetable oils and mineral oil insoluble, or solubility is very small, both ability to high temperature, and low temperature. Chemical inertia, stable physical properties, no biological activity. Organic silicone defoamer is a white viscous emulsion.
Rubber additives in the storage and use of the process often appear sticky, harden crisp or crack and other aging phenomenon, causing this problem, mainly in the following categories: 1. Oxygen: Oxygen will react with the rubber molecules in the rubber additives to cause the molecular chain to break or over-crosslink, so that its performance changes. 2. Thermal: The temperature
The global automobile industry has been steadily launched, driving the consumption of rubber chemicals. The output of China’s rubber chemicals accounts for more than 70% of the world’s total, environmental protection tightens, supply is shortened, and prices rise substantially in 2017, and it is estimated that it will be stable in 2018. Let’s take a closer look at the results
Rubber chemicals are dangerous goods, flammable and explosive. Such as curing agent, oil, carbon black, organic accelerator and antioxidant.
Common high-temperature cable will be wrapped with a layer of “rubber protective layer”, when such a protective layer is damaged, the high-temperature cable inside will be damaged, so can not continue to use, so manufacturers will peripheral rubber protective layer anti-aging Processing, this process involves the antioxidant. The first point: Because of the different characteristics of each antioxidant, and different
Wire and cable will be subject to heat, oxygen, mechanical stress, light, high energy radiation and other factors in the usage, gradually aging, resulting in reduced product insulation properties. In order to extend the service life of wire and cable, cable manufacturers often use rubber antioxidant, but the protective effect of each antioxidant have limitations, and wire and cable and
