Description

CHLUMIAO® DBHQ Usage

Antioxidant DBHQ is a multi-phenolic antioxidant with dual functions of antioxidant and light stabilizer, capable of absorbing 280-310nm UV light. It has the characteristics of no coloring, low volatility, high temperature resistance and extraction resistance, etc. It is suitable for polyethylene, polypropylene, polyformaldehyde, polyvinyl chloride, polystyrene, polycarbonate and cellulose ester. Especially suitable for latex and adhesive. It is used as an antioxidant for natural rubber and synthetic rubber to delay the thermal and oxygen aging of vulcanized and unvulcanized rubber and to improve heat resistance, oil resistance and flexural properties. It can be used together with DNP as antioxidant, and the synergistic effect is obvious. It is used as antioxidant for biofuel and lubricating grease to improve the temperature resistance of biofuel, prevent high temperature oxidation, interrupt oxidation chain reaction, inhibit alkylation, oxidation, polymerization and decomposition of lubricating grease, and avoid the formation of coke and other gums. It is used in combination with phosphate ester and thioester antioxidants to achieve outstanding antioxidant performance. Used as polymerization inhibitor for butadiene, styrene, vinyl acetate and vinyl resins, good compatibility with polyester resins, does not affect the physical properties of polyester resins. Used in photographic products processing and storage process, inhibit the developer’s oxidation products in the emulsion layer between the diffusion of dyes, photographic properties change to generate gray mist. The general dosage is 0.1-1.0%.

Antioxidant DBHQ Application scenarios

1. Anti-aging of rubber and latex products:

Used in natural rubber, styrene-butadiene rubber, butadiene rubber, nitrile rubber, neoprene rubber, etc., it inhibits thermo-oxidative aging and UV aging, without coloring or pollution, and improves heat resistance, flexural crack resistance, etc. Suitable for light-colored/transparent products, medical supplies, food contact parts, latex gloves, condoms, medical catheters, latex products, and tapes, etc. The typical addition amount is 0.5-1.0 parts, which does not affect vulcanization.

2. Stabilization of polyolefins and polyoxymethylene:

As a thermo-oxidative and light stabilizer for PP, PE, polyoxymethylene, etc., it prevents degradation, discoloration, and decline in mechanical properties during processing and use. It can be used in food contact polyolefin packaging materials, often in synergy with phosphites and thioether antioxidants.

3. Engineering Plastics and Elastomer Protection:

Suitable for engineering plastics such as PBT, PET, and nylon, as well as elastomers such as SBS and SEBS. Inhibits thermo-oxidative degradation during high-temperature processing and long-term use, ensuring dimensional and appearance stability of products. Suitable for automotive parts, electronic and electrical housings, etc.

4. Industrial Greases and Fuels Antioxidant:

Added to mineral oils, synthetic lubricants, hydraulic oils, and fuel oils, inhibits oxidative rancidity and gum formation, extends oil life, protects equipment from oxidation product corrosion, and improves lubrication system stability.

5. Adhesives and Sealants Anti-aging:

Used in epoxy, polyurethane, acrylic, and other adhesives and sealants, inhibits thermo-oxidative and photo-aging, extends shelf life and service life, maintains bond strength and elasticity, and is suitable for structural adhesives and seals in construction, automotive, and electronics industries.

6. Coating and Paint Stabilization:

Used as an antioxidant and light stabilizer in solvent-based coatings and powder coatings to prevent yellowing, chalking, and cracking during high-temperature curing and outdoor use, improving weather resistance and gloss stability. Suitable for automotive paints, industrial anti-corrosion paints, and outdoor architectural coatings.

7. Auxiliary Stabilization of Synthetic Resins and Polymers:

Used in synthetic resins such as polystyrene, ABS, and PVC to prevent thermo-oxidative degradation during processing and use, improving color and mechanical property stability. Suitable for light-colored or transparent products such as appliance casings and daily necessities.
