Sulfur, white and shiny crystal compounds. The taste is bitter, density is 1.405, and the melting point is 180 to 182 ° C. Decomposition when it is hotter, soluble in water, can be dissolved in ethanol when heating, and is slightly dissolved in ether. During the melting, heterogeneity is partialized to form ammonium thiocyanomylisocyanomylocyne. The raw materials used to make drugs, dyes, resins, and plastic powder, and are also used as a vulcanized promoter for rubber, flotal agents for metal minerals.

Aspirational antioxidants should have the following conditions:
①Should have high anti-oxidation ability;
②Good compatibility with resin, no precipitation;
③Good processing function, non-volatile and non-decomposing at the processing temperature of high polymer;
④Good resistance to extraction, insoluble in water and oil;
⑤The color of itself is best to be colorless or light-colored, so as not to pollute the product;
⑥Non-toxic or low-toxic;
⑦Low price.
In fact, any kind of antioxidant can not fully meet these conditions.

Titanium dioxide naturally exists in titanium ores such as titanium ore and rutile. Its molecular structure gives it high brightness and covering properties, but it must first be chemically extracted and purified. More than 60 years ago, DuPont invented the chlorinated titanium dioxide production process. Compared with the old sulfuric acid process, it can manufacture high-quality pigment products while reducing environmental emissions and Chemicalbook energy consumption.
Acrylic paint is a one-component self-drying weather-resistant and anticorrosive paint made by advanced technology based on traditional acrylic resin and added with long-life chlorosulfonated polyethylene rubber, weather-resistant pigments and fillers, and weather-resistant additives recognized by China and foreign countries.
When the PH cost of the ammonia water is small, the supersaturation of the reaction is small, so the obtained magnesium hydroxide has a large particle length and a quick sedimentation speed; whilst the PH price of the ammonia water is tremendously large, the response supersaturation is enormously large, and the sedimentation time of the magnesium hydroxide lengthy.
A kind of hydroperoxide decomposer that destroys the structure of peroxygen, called auxiliary antioxidant, mainly contains thioester and phosphorous acid, and is often used together with the main antioxidant.
Antioxidant is a kind of plastic additives that can effectively reduce the self-oxidation reaction speed of plastic materials and delay its aging degradation. It has a wide range of applications and is widely used in various polymer material products.
