Product Description：

Antioxidant 1098 is a highly efficient hindered phenolic primary antioxidant, which is widely used in the stabilization process of various polymer materials. Its main function is to provide excellent thermal processing protection and long-term resistance to aging and degradation. As a general antioxidant, it is especially suitable for stabilizing the production process of polyamide injection molding, fibers and films. The molding material has better stability and longer stability time.

Properties and Usage:

Features:

1. Excellent heat resistance and extraction resistance,

2. Good non-staining property in the initial stage,

3. Colorless pollution, low volatility

4. And excellent compatibility with most polymer materials.

5. The material with strong extraction resistance has excellent aging resistance and decomposition resistance.

Scope of application:

1. Polyamide: Used as a stabilizer to stabilize polyamide injection molding.

2. Organic basic materials such as polystyrene, polyolefin, ABS resin, acetal resin, polyurethane: provide stabilization treatment for these materials. Effectively prevents discoloration caused by high temperatures.

3. Fiber material: added to synthetic fibers to give the material good oxidation resistance.

Recommended usage: Use in the same way as thioester antioxidants produced by Fscichem, such as DLTDP and DSTDP.

Dosage: 0.05-0.5% is optimal, and can be used according to the specific formula.

Storage conditions: In a dry and cool environment, avoid high temperature during storage and transportation, and pay attention to waterproof and moisture-proof.

Packing: This product uses two kinds of carton lined with plastic bags and paper bags, with a net weight of 25 kg 500kg. It can also be made according to customer requirements
