  • 1. Advanced Technology The factory utilizes the latest technology in HEC production, ensuring the highest quality and consistency of the final product.
  • The gelation temperature of HPMCP refers to the temperature at which the polymer undergoes a phase transition, changing from a solid state to a gel-like consistency. This transition is crucial for controlling the release of drugs encapsulated within HPMCP-coated formulations. When exposed to body temperatures during digestion, the HPMCP coating begins to soften and eventually forms a gel layer. This layer acts as a barrier, preventing premature drug release in the stomach while allowing controlled release in the intestine.
