Plastic Antioxidant FAQ

Q:What is antioxidant 168?

Antioxidant 168 is a kind of high-efficiency and nonpolluting antioxidant. It is an effective antioxidant for natural rubber, synthetic rubber, latex and other polymers. It can also be used as antioxidant for petroleum products, such as diesel oil and gasoline.

Q:What is secondary antioxidant?

Secondary antioxidants are strong inhibitors of chain reactions, and their effectiveness is especially high when the primary antioxidant is present in small amounts. It is important to understand that secondary antioxidants are not necessarily more potent than primary antioxidants in terms of their ability to quench free radicals.

Q:How does antioxidant work?

Oxidative stress is a chemical reaction that can produce free radicals, damaging compounds in the body that alter or destroy cells. Free radicals are waste products of normal body processes, and they cause damage by stealing electrons from neighboring molecules. The human body produces antioxidants to counteract this damage.

Q:What is BHT used for?

BHT is also known as Butylated hydroxytoluene. It’s one of the most popular food additives in use. It prevents oils from oxidizing. Oxidized oil can become rancid, which is why antioxidants like BHT are used to prevent this process and keep foods fresh.

Q:What is irganox used for?

It is used to protect a wide range of polymers including polyolefins (e.g. PE, PP), polybutadiene rubber and styrenics (e.g. PS and ABS) against thermo-oxidative degradation during processing and long term thermal aging at elevated temperatures.

Q:Is antioxidant a preservative?

No, antioxidant is not a preservative. The purpose of an antioxidant is to prevent the oil in your food from going rancid. Preservatives are chemicals that inhibit or retard spoilage caused by microbial growth or decomposition.

Q:What is the chemical compound for 1010?

There is no chemical compound for 1010. Chemical compounds are made up of elements. The number 1010 can be a chemical formula or a molecular formula, but it CANNOT be a chemical compound because it is not made up of element symbols.

Q: What is Irganox b215?

Irganox b215 is a secondary antioxidant that works well in polymers, plastics, elastomers, and rubbers. Irganox b215 is also an excellent synergist with primary antioxidants.
