High-temperature resistant integral molded gas-filled seal

Integral molded inflatable seal have strong heat resistance. This comes from three main areas: material choice, design, and making process. Here’s a clear breakdown:   Material Choice   Heat-resistant materials like silicone rubber (VMQ) and fluororubber (FKM) are used. These keep stable in high heat, so seals last long. Adding heat-resistant additives or mixing materials can boost heat limits. For example, special fillers in silicone rubber raise its heat tolerance. Design   The shape and size are made to handle heat expansion and stress. This cuts stress points at high temps, improving heat resistance. The inflation design adjusts pressure with heat. As temp rises, more air can be added to keep a tight inflatable seal, even if gaps change. Making Process   Molding creates a uniform structure with no weak spots. This helps seals work better in high heat. Heat treatment removes internal stress and improves heat resistance. It also keeps the seal’s size and seal power stable. Heat Perf…
