Knowledge Related to Rubber Additives

July 09, 2024

Rubber additives include chemicals, accelerators, active agents, anti-scorching agents, anti-aging agents, reinforcing agents, fillers, plasticizers, coloring agents, foaming agents, and latex compounding agents. Rubber accessories include: sulfur, zinc oxide, magnesium oxide, paraffin wax, light-colored solid marlon, dark solid marlon, stearic acid, zinc stearate, titanium dioxide, light calcium, clay, barium sulfate and so on.
DTBHQ is one of the widest range of industrial antioxidants, but also a wide range of polyester polymerization inhibitor. Color photographic materials in the process and storage, due to the oxidation products of the developer in the emulsion layer of diffusion caused by the non-selective generation of dyes, so that changes in photographic properties and produce gray fog pollution, DTBHQ can be added to avoid this phenomenon.
Chemical name: 2,5-di-tert-butylhydroquinone;
English abbreviation: DTBHQ、DBHQ;
Molecular formula: C14H22O2
Molecular weight: 222.2;

Performance: This product is Light brown crystalline powder, almost insoluble in water, slightly soluble in benzene and gasoline, easily soluble in acetone, ethanol and ethyl acetate. 100g of acetone, ethanol and ethyl acetate can dissolve 39g, 35g and 49g of this product respectively at 25℃.

Di Tert Butylhydroquinone

Use range:
It is widely used in synthetic rubber, plastic, and resin industries. Applicable to natural rubber, synthetic rubber and latex, polyolefins and polyoxymethylene and other plastics, resins and engineering plastics modified UV absorbers; all kinds of rubber, developing materials, resins, plastics, oils and adhesives. It is a non-toxic, non-perfect odor, non-polluting plastic and resin polymerization inhibitor. It acts as an inhibitor, especially as an antioxidant in a low-pressure environment. It makes the unsaturated polyester very stable during production and storage.
Used as an anti-emulsion for natural rubber, synthetic rubber and latex, it can retard the oxidation and ultraviolet light aging of plasticized and non-gelatinized rubber. It is a non-polluting rubber product, does not discolor in sunlight, has no coloration, and is non-polluting. The antioxidant is superior to the usual antioxidants in terms of oxidation resistance, and can also improve the heat resistance and flex cracking resistance of rubber products. The effective addition amount is 0.1-2%. This product is also good for anti-aging effect of adhesives. It is also used to make light-colored rubber products, medical supplies, dairy products, and adhesive tapes.

It can also be used as an antioxidant for oils and synthetic resins. It can be used as a heat and light stabilizer for polyolefins and polyoxymethylene in the plastics industry.

Di Tert Butylhydroquinone

Advantages:
It can delay the oxidation, aging and ultraviolet light aging of the plasticizer, and does not pollute the product; it can improve the heat resistance, oil resistance and crack resistance of the rubber products; it is easy to disperse and has no effect on the conversion. Particularly suitable for the manufacture of light-colored rubber products, medical supplies, latex products and adhesive tapes,it is a widely used effective inhibitor; has sufficient solubility and chemical stability in polyester solvents; does not affect the resin Physicochemical properties; very few dosages can achieve good results.
