Roto-molding Toughening Agent For Impact Resistance And Cold Resistance

Roto-molding toughening agent for impact resistance and cold resistance

Rotational toughening agent is a kind of toughening agent specially used in rotational molding process. It can significantly improve the impact strength and toughness of rotational molding products, so that the products can still maintain good performance in various harsh environments. The following is a detailed introduction to rotational molding tougheners:

1. Definition and function
Toughening agents refer to substances that can increase the flexibility of the adhesive film layer, while rotomolding tougheners are specifically designed for the rotomolding process. In the process of rotational molding, the raw materials are heated, melted, cooled and solidified to form a product. The addition of a rotational molding toughening agent can significantly improve the toughness of the product, making it less likely to break when impacted.

Dispersed phase toughening: The toughening agent forms a dispersed phase in the resin matrix. When the product is impacted by external forces, the dispersed phase can absorb energy and disperse stress, thereby improving the toughness of the product.
Initiating silver cracks and terminating cracks: When certain nanoparticles are used as toughening agents, they can induce silver cracks in the matrix and terminate the expansion of cracks, thus improving the anti-cracking performance of the product.
4. Application areas
Rotomolding tougheners are widely used in various rotomolded products, such as plastic containers, toys, auto parts, etc. After adding rotomolding tougheners to these products, their impact strength and toughness can be significantly improved to meet the needs of use in various harsh environments.
