Plastic tougheners are additives that enhance the toughness of plastics while reducing their brittleness. Typically, tougheners undergo physical or chemical reactions with resins to improve their mechanical properties. Common tougheners include silicone rubber, thermoplastic elastomers, and amorphous polyolefins.

Thickeners are primarily used to enhance the toughness of plastic products, reducing their brittleness to prevent cracking or damage under external forces. Common applications include electrical cables, auto parts, toys, and packaging materials.

The addition methods of toughening agents primarily consist of two types: physical blending and co-molding. Physical blending involves separately adding the toughening agent and resin into a blending machine, mechanically mixing them, and then removing the finished product. Co-molding, on the other hand, entails first adding the toughening agent and resin together into a co-molding machine, and then blending them using high-speed stirring.

Usage Precautions for Detergent Additives

1. The selection of toughening agents should be reasonably matched based on the type of resin and usage requirements.

The amount of toughening agent should be properly controlled; too much or too little can affect the performance of the product.

When adding the toughening agent, pay attention to the uniformity of mixing to prevent local accumulation of the toughening agent.

4. The addition of toughening agents may affect the transparency and appearance of the material, so selection should be based on actual requirements.

5. Plasticizers may affect the physical and chemical properties of the product, so a comprehensive consideration is necessary when selecting plasticizers.
