The core of a chemical anchor lies in its two primary components the resin and the hardener. The resin, typically epoxy or methacrylate-based, is a liquid polymer that, when combined with the hardener, initiates a chemical reaction, leading to the formation of a solid, robust structure. The hardener, often a catalyst, accelerates this polymerization process, turning the liquid mixture into a rigid material capable of withstanding immense loads.

  • 1: What is HPMC?
    Hydroxypropyl methylcellulose ( (Propylene glycol ether of methylcellulose) is a methylcellulose modified with a small amount of propylene glycol ether groups attached to the anhydroglucose of the cellulose. The dry product contains 19 to 30 per cent of methoxyl (-OCH3) groups and 3 to 12 per cent of hydroxypropyl (-OCH2CHOHCH3) groups. HPMC can be derived from tree fiber or cotton fiber.

    2: How HPMC is made:
    The cellulose ethers are manufactured by a reaction of purified cellulose with alkylating reagents (methyl chloride) in presence of a base, typically     sodium hydroxide and an inert diluent. The addition of the base in combination with water activates the cellulose matrix by disrupting the crystalline structure and increasing the access for the alkylating agent and promotes the etherification reaction. This activated matrix is called alkali cellulose (Kirk-Othmer, 1993). During the manufacture of HPMC alkali cellulose reacts with methyl chloride to produce methyl cellulose and sodium chloride. Side reactions of the methyl chloride and sodium hydroxide produce methanol and dimethyl ether by-products. The methylcellulose is then further reacted with the staged addition of an alkylene oxide, which in the case of HPMC is propylene oxide (Kirk Othmer, 1993 Dow, 2002). After this reaction, MC and HPMC are purified in hot water, where they are insoluble. Drying and grinding completes the process.

    3: Chemicals agents and reactions:
    The chemical reactions of manufacturing HPMC summerize as following:

  • 1. Pharmaceutical Applications


  • 2. Cosmetics and Personal Care In the cosmetics industry, HEC is employed as an emulsifier and thickener in lotions, creams, and shampoos. Its ability to improve texture and enhance moisture retention makes it a favored ingredient in various personal care products.
