Rubber Sulphur HS
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 ℃.

Performance: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 ℃.
Use:Sulfur powder in rubber products is mainly played the role of vulcanization, sulfur powder in industry are called additives, mainly used for processing rubber, plastic, plastic and so on. In rubber products from vulcanization crosslinking, sulfur bonds and two ethylene bonds crosslinking, the formation of-C-S-C-bond, and then give the rubber to use the basic physical properties.
Packing:Composite paper bag, lined with plastic film bag, net weight 25kg.
Storage: Sealed and stored in a cool, dry, well-ventilated place, avoid direct sunlight, and avoid fire.
Safety and toxicity: Please refer to the relevant product safety data (MSDS).
