Hebei Hankai gear box oil seal
One of the primary characteristics of high temperature oil seals is their ability to maintain flexibility and resilience at elevated temperatures. Traditional rubber seals may become brittle and lose their sealing capabilities when exposed to heat. In contrast, high temperature oil seals retain their mechanical properties, ensuring that they continue to perform their sealing function effectively even in harsh conditions. Typically, these seals can withstand temperatures ranging from 150°C to over 300°C, depending on the specific material used.

HPMC is extensively utilized in the pharmaceutical industry. It acts as a binding agent in tablet formulations, ensuring uniformity and stability. Its gel-forming ability makes it an excellent excipient for controlled-release drug formulations, allowing for the gradual release of active ingredients over time. Furthermore, HPMC is used in ophthalmic solutions as a lubricant, providing relief for dry eyes and enhancing the comfort of contact lenses.
