PRODUCTS CENTER
The product melting point of 62 ℃, flash point of 188 ℃, the proportion of 1.16~1.17; slightly soluble in water; soluble in acetone, acetic acid ethyl ester, benzene, carbon tetrachloride, ethanol, gasoline.
Soluble in acetone, ethyl acetate, benzene, carbon tetrachloride and ethanol, soluble in gasoline, slightly soluble in water. Exposure to sunlight and air will gradually turn purple.
This product has excellent anti-ozone aging performance, thermal oxygen, weather aging also has obvious protective effect.
Amber to brown flake, non-toxic. Relative density 1.05, soluble in benzene, acetone, chloroform and carbon disulfide, slightly soluble in petroleum hydrocarbons, insoluble in water.
White crystal or powder, belonging to the hexagonal crystal system. Odorless, non-toxic, no sand, fine quality. Density 5.606g/cm3, refractive index 2.0041,1800 C sublimation. The tinting strength is 2 times that of basic lead carbonate, and the hiding power is half of that of titanium dioxide and zinc sulfide. Insoluble in water and ethanol, soluble in acid, sodium hydroxide, ammonium chloride, is an amphoteric oxide. It is yellow when heated at high temperature and returns to white after cooling. In the humid air can absorb carbon dioxide and moisture gradually become basic zinc carbonate. It can also be reduced to zinc metal by carbon or carbon monoxide. There is excess zinc in the zinc oxide lattice, the initial ionization energy of zinc is relatively low, easy to lose electrons, and zinc oxide electron mobility is much larger than the hole mobility, can be regarded as n-type semiconductor.
It is a non-toxic, flammable yellow powder named for its insolubility in carbon disulfide. It is made by ordinary sulfur thermal polymerization, the number of sulfur atoms on the molecular chain is as high as 108 or more, there is a polymer viscosity and molecular weight distribution, so also known as elastic sulfur or polymeric sulfur, belongs to inorganic polymer chemical raw materials.
Sulfur, commonly known as sulfur, powder is light yellow powder, has a special odor, soluble in carbon disulfide, insoluble in water. There are many allotropes. orthorhombic sulfur is also called rhombic sulfur or α-sulfur. It is very stable below 95.5 ℃, with a density of 2.1g/cm3, a melting point of 112.8 ℃, a boiling point of 445 ℃, brittle and difficult to transfer heat and conduct electricity. Monoclinic sulfur, also known as β-sulfur, is stable above 95.5 with a density of 1.96g/cm3. Elastic sulfur, also known as γ-sulfur, is amorphous and unstable, easily converted to alpha-sulfur. Both orthorhombic sulfur and monoclinic sulfur are composed of S8 cyclic molecules, which are composed of chain molecules in liquid state, S8, S4, S2 and other molecules in vapor, and S2 is composed of S2 above 1000 ℃.
EPDM special comprehensive accelerator, can also be used for NBR, SBR and other rubber products.
Soluble in acetone, benzene, chloroform, carbon disulfide, ethanol, slightly soluble in gasoline, insoluble in water; non-toxic.
Chemson Industrial (Shanghai) Co., Ltd. was established in 1998. The main production of rubber chemicals, high-purity ultra-fine alumina and aluminum isopropoxide, aluminum sec-butoxide and other intermediate products.
