Zinc Borate is an environmentally friendly non -halogen flame retardant. It has the characteristics of non -toxic, low -water solubility, high heat stability, small particle size, small gravity, and good decentralization. As a high -efficiency flame retardant Rubber, coatings and other fields.

Molecular weight: 65.39 Grade: 5N MDL number: MFCD00011291 EC number: 231-175-3

Dibenylmethane diisocyanate, referred to as "MDI", is an organic substance, a chemical formula C15H10N2O2.

Hydrogen Peroxide Solution is an aqueous solution of hydrogen peroxide.

Appearance: Light yellow to white granular crystals (semi-circular) white to light yellow loose crystals, heating is made black. Microfincture. Content: ≥ 85% Melting point: 98-102 ° C Dry loss: ≤0.2%

In fact, any kind of antioxidant can not fully meet these conditions. Therefore, in actual application, it is often based on the variety, use and processing method of engineering plastics, using the strengths of various additives and cooperating to produce synergistic effects.

The toluene diisocyanate has 2,4-toluene diisocyanates and 2,6-toluene diisocyanate (TDI).

Common tetra-group lead, ferrocene, MMT (methylcyclopentadiene trikarbonyl manganese) or CMT is common, because metal deposits can occur in the inside of the launching machine, resulting in a cylinder wear, spark plug ignition Poor problems such as poisoning, oxygen sensors and ternary catalysts, have been prohibited or constrained. The addition of tetra-element and ferrocene added is known as national standards, and the manganese-based anti-explosive agent is strictly constrained (the detection limit is less than 0.018 g / L).

Antioxidant is a kind of chemical substance. When it is only a small amount in the polymer system, it can delay or inhibit the progress of the polymer oxidation process, thereby preventing the aging of the polymer and prolonging its service life. It is also called " Anti-aging agent".

The octane is the most important quality indicator of the vehicle gasoline.

it can also be used as high octane gasoline components, is an important raw material for organic chemicals. It can also be used to remove the bitumen of the body. The hospital pathology is primarily used for tissue, slice of pilot and dewaxing.

Glass material is referred to as a glass instrument. Many glass instruments are used in the laboratory, which is highly chemically stable, thermal stability, and well-transparent, and good insulation function.

M-xylene is an organic compound with a molecular formula C8H10, a molecular weight of 106, a colorless concussion liquid, a odor like toluene.

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.

A substance that can reduce the surface tension of water, solution, suspension, etc., prevent the formation of foam, or reduce or eliminate the original foam. [1]

Appearance and properties: colorless liquid, almost odorless Molecular weight 90.12 Vapor pressure 0.51 kPa/20℃ Flash point: 43℃ Melting point -70°C boiling point: 135.1°C solubility can be miscible with water and most organic solvents such as ethanol Density (D4) 0.925-0.935

Chemical nature: Forbidden qualitative: strong oxidizing agent, strong reducing agent, strong acid, strong base. Ecological nature: Ecotoxicity EC50: 1.2 ~ 1.51mg / L (luminous bacteria, microtox toxicity test) Biodegradability Miti-I test, initial concentration of 100 mg / L, sludge concentration 30 mg / L, 2 weeks later degraded 77%. Non-biodegradability In the air, when the hydroxyl radical concentration is 5.00 × 105 / cm3, the degradation of the half-life is 7.8d (theory). Other harmful effects The material is damaged by the environment and should pay spe

The propanol, but also glycerol, chemical formula is C3H8O3, colorless, odorless, sweet, and appearance showing a clear liquid, is an organic substance, can absorb moisture from air, can also absorb hydrogen sulfide, hydrogen cyanide and sulfur dioxide .
