Adding toughening agents: Adding toughening agents such as CPE to PVC raw materials can effectively improve the impact strength and toughness of the material, thereby reducing the embrittlement phenomenon at low temperature.
Use low-temperature resistant materials: Choose low-temperature resistant PVC materials, and its molecular structure and formula design can better adapt to the low-temperature environment and reduce embrittlement phenomenon.
Improve the production process: ensure adequate plasticization, avoid insufficient or excessive plasticization, and optimize the mold design and extrusion process, reduce internal stress, and improve the quality of products.
Through the above measures, the performance of PVC film in low temperature environment can be effectively improved and the occurrence of embrittlement phenomenon can be reduced.
