In various mechanical devices, household appliances, and even precision instruments, sealing performance is directly related to system safety, efficiency, and service life.
Cross-link density is the core factor that determines the tear strength of liquid silicone fresh-keeping box.
From the perspective of material mechanics, silicone buttons with lower Shore hardness have higher flexibility and deformation space.
In contrast, liquid silicone fresh-keeping boxes, with their superior temperature resistance, are becoming an all-rounder in the kitchen, easily handling extreme temperatures from freezing to scorching, providing users with a safer and more convenient din
The core of the vulcanization process is to transform the linear molecular chains of liquid silicone into a three-dimensional network structure through chemical cross-linking.
The key to silicone sealing gaskets' effective UV resistance and significantly extended service life lies in their unique material nature—a structurally stable polymer system that is insensitive to high-energy UV light.
