Antioxidant TNP is an efficient, non-polluting, heat-resistant antioxidant that is widely used in the rubber and plastics industries, especially suitable for synthetic rubber, natural rubber and various polyolefin plastics. This product can not only improve the heat resistance and antioxidant capacity of the material, but also effectively prevent the color change of the product during processing and use. It is an ideal choice for white and brightly colored products.
Main features and advantages:
1. Non-pollution: TNP is a non-pollution antioxidant and has no effect on the color of the product. It is especially suitable for high-standard products that require no color change.
2. Heat resistance: able to remain stable in high temperature environments and extend the service life of the product.
Prevent resinization and yellowing: During rubber processing, TNP can effectively prevent resinization and yellowing, maintaining the beauty and performance of the product.
3. Improve light stability: In materials such as polyvinyl chloride (PVC), polystyrene (PS), vinyl fluoride polymers and ABS copolymers, TNP can significantly improve light stability and prevent the discoloration of alkylphenols.
Application scope:
1. Synthetic rubber and natural rubber: As a non-discoloring stabilizer, TNP has no effect on the vulcanization process, and can soften rubber and inhibit the formation of gel.
2. Polyolefin plastic: Among various polyolefin plastics, TNP can effectively prevent gelation and improve the aging resistance of the material.
3. Adhesive: Adding TNP to the adhesive can maintain its adhesion and improve the protective effect.
Packing:
This product is packed in galvanized iron drum, net weight 200KG/drum, and can also be customized according to customer requirements
Storage conditions:
This product should be stored in a dry and cool environment, avoid high temperature during storage and transportation, and pay attention to waterproof and moisture-proof. When handling this product, avoid strong rubbing to prevent damage to the package.
