PA66 toughening

characteristic

1. High impact resistance: Toughened PA66 can absorb more energy when impacted by external forces, reduce the generation and expansion of cracks, and effectively prevent the product from rupturing. This makes the toughened PA66 excellent in mechanical parts or sports equipment that need to withstand dynamic loads, significantly improving the service life and reliability of the product.

‌2. Good thermal stability‌: Toughened PA66 has good thermal stability in a wide temperature range and can be used in high temperature environments, such as some components in the automobile engine compartment, heat dissipation structural parts of electronic equipment, etc. Its loaded heat-resistant deformation temperature can reach 200℃, and continuous use heat-resistant temperature can reach 150℃‌

‌3. Excellent low-temperature toughness‌: Ordinary PA66 is prone to become brittle at low temperatures, while toughened PA66 has good low-temperature toughness and can still maintain good flexibility and impact resistance in low-temperature environments. This is especially important for some products used in cold areas or under low temperature conditions‌

4. Improved processing performance: The addition of some toughening agent can reduce the melt viscosity of PA66, improve its fluidity, and make it easier to fill the mold cavity, thereby improving production efficiency and reducing the difficulty of forming and processing. The toughened PA66 has good surface lubricity and can be easily removed from the mold after forming, reducing the adhesion between the product and the mold, which helps improve the surface quality and production efficiency of the product.

5. Other characteristics: Toughened PA66 also has good tensile strength and bending strength retention rate. Although the addition of toughening agent will reduce the tensile strength and bending strength of PA66 to a certain extent, by reasonably selecting toughening agent and optimizing formula, a high strength level can still be maintained. In addition, the toughened PA66 has a chemical corrosion resistance similar to that of ordinary PA66 and can be used in some occasions with harsh chemical environments‌
