According to one month since the start of construction after the holiday, the price increase frenzy in the silicone market is out of control, and the situation is fierce. Shandong Luxi has adjusted th......
2021-03-15On March 7, the silicone DMC commodity index was 126.46, which was the same as yesterday. It was 26.40% lower than the highest point in the cycle of 171.82 points (2020-12-01), and 79.63% higher than ......
2021-03-10Generally speaking, because the reinforce effect of precipitated silica (except for ultrafine, surface treatment) is not as good as carbon black, it is a semi-reinforcing filler material. Therefore, t......
2021-03-09There are many types of carbon black, such as pigment carbon black, special carbon black, white carbon black, etc. Among them, white carbon black is a special kind of carbon black with white color and......
2021-03-08(1) High and low temperature resistance Among all rubbers, silicone rubber has the widest operating temperature range (-100 to 350°C). For example, properly matched vinyl silicon......
2021-03-02(1) Surface dry time It refers to the time it takes for one-component room temperature vulcanized silicone rubber to lose its viscosity when exposed to the atmosphere during curing. Ordinary refers t......
2021-02-27Because of the large surface area of silica, it tends to accumulate twice. In addition, it is easy to absorb water in the air, which makes it easy to produce strong hydrogen bond association between h......
2021-02-26Silica can be used as a reinforcing agent for rubber, and its reinforcing performance is even better than that of pigmented carbon black after ultra-fine treatment. It is more suitable for making ligh......
2021-02-25Because of the large specific surface area of white carbon black, it always tends to re-aggregate. In addition, it is easy to absorb water in the air, which makes it easy to produce strong hydrogen bo......
2021-02-242. Modification of white carbon black coupling agent The principle of coupling agent modification is to use part of the functional groups on the coupling agent to chemically react with the hydroxyl......
2021-02-23At present, the industrial production of white carbon black is mainly based on the precipitation method. The surface of the white carbon black produced contains a large number of polar groups such as ......
2021-02-22Silica is an indispensable additive for the preparation of dry powder fire extinguishing agents at home and abroad, the purpose is to prevent the dry powder fire extinguishing agent from caking during......
2021-02-20Silicone rubber is the largest and most widely used category of silicone products. After vulcanization, silicone rubber has excellent high and low temperature resistance, weather resistance, water rep......
2021-02-15Space conditions have a unique set of theories, and there are many restrictions on the technology that brings humans to space. Of course, rigorous space exploration is usually the driving force for ma......
2021-02-08Precipitation method silica can be roughly divided into three categories: one is "standard" traditional silica (LDS), the other is easy-dispersible silica (EDS), and the third is high-dispersion si......
