Calcium zinc stabilizers are widely used in the production process of shoe soles, especially in PVC foam shoe sole materials.
Calcium zinc stabilizer is an environmentally friendly heat stabilizer mainly used in the processing of PVC and other plastic materials to improve their thermal stability and weather resistance. The main function of calcium zinc stabilizers in shoe sole foam materials is to prevent the material from decomposing due to high temperatures during processing, ensuring the quality and performance of the shoe sole. It helps maintain the physical and chemical stability of the sole, thereby extending its lifespan.
In addition, calcium zinc stabilizers also have good lubricity and dispersibility, which helps improve the processing performance and surface glossiness of shoe soles. The addition amount, dispersion uniformity, and combination with other additives of calcium zinc stabilizers are key factors affecting the quality of shoe soles during the production process.
However, it should be noted that excessive or unevenly dispersed calcium zinc stabilizers may cause yellowing of the shoe sole. This may be due to the chemical reaction of stabilizers in high concentration areas during the high-temperature foaming process. Therefore, it is necessary to strictly control the addition amount and dispersion uniformity of calcium zinc stabilizers in the production process to avoid this problem.
Overall, calcium zinc stabilizers play an important role in shoe sole production, but they also need to be used reasonably to avoid potential problems.
