Antioxidant KY-405

This product is one of the rare antioxidant varieties among amines that are non-toxic, odorless, and light-colored.

Antioxidant KY-616

Primarily used to protect light-colored and non-polluting compounds, such as natural rubber, sealants, ABS, BR, IR, NBR, NR, SBR, SBS, SIS, and other derivatives.

Antioxidant KY-86

KY-86 is a versatile antioxidant suitable for use in chloroprene rubber (CR), natural rubber (NR), isoprene rubber (IR), butadiene rubber (BR), styrene-butadiene rubber (SBR), nitrile rubber (NBR), and ethylene-propylene-diene monomer rubber (EPDM)—as well as their blends.

Antioxidant BLE

It can be used as a general-purpose antioxidant in natural rubber as well as synthetic rubbers and latexes such as chloroprene, nitrile, styrene-butadiene, and cis-butadiene.

Antioxidant KY616-5

KY616-5 antioxidant is a cost-effective emulsion-type antioxidant formulated by combining a sterically hindered phenol polymer with an auxiliary antioxidant. It provides highly effective anti-oxidation properties and long-lasting storage stability for both natural and synthetic latexes. Additionally, it features non-staining and colorfast characteristics, helping to prevent yellowing of products during processing.

Antioxidant DLTDP

This product is an excellent auxiliary antioxidant, widely used in synthetic materials such as polyethylene, polypropylene, polyvinyl chloride, ABS, and MBS. It can also be applied in rubber processing and lubricating oils.

Antioxidant KY-01

1. Extremely low volatility, resulting in virtually no evaporation loss during use; 2. A versatile and highly effective antioxidant designed to prevent oxidation of a wide range of mineral and synthetic oil-based lubricants in high-temperature environments; 3. Effectively controls sludge formation even at extremely high temperatures, helping to keep equipment clean; 4. A high-purity product that is less prone to discoloration compared to other diphenylamine derivatives.

Antioxidant BHT/264

This product is suitable for various animal and vegetable oil products, as well as a wide range of grain and oil foods, snack foods, food packaging materials, and food-grade plastic products, among others.
