  • 1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.

  • Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on hydroxypropyl methyl cellulose as a feed additive for all animal species. Hydroxypropyl methyl cellulose is intended for use as a technological additive (functional group: stabiliser) in premixtures and feedingstuffs for all animal species with no minimum and maximum content. A proper identification and characterisation of hydroxypropyl methyl cellulose as required for a feed additive is not available and the occurrence of potential toxic impurities cannot be assessed. The following conclusions apply only to hydroxypropyl methyl cellulose meeting the food additive specifications. The FEEDAP Panel concluded that hydroxypropyl methyl cellulose is considered safe for all animal species. The use of hydroxypropyl methyl cellulose in animal nutrition is of no concern for consumer safety. In the absence of data, the FEEDAP Panel was not in the position to conclude on the safety of hydroxypropyl methyl cellulose for the user. The use of hydroxypropyl methyl cellulose as a feed additive is considered safe for the environment. The additive is considered to be efficacious in feedingstuffs for all animal species.

  • China's HPMC industry has grown exponentially over the years, driven by a combination of factors. The country boasts an abundance of raw materials, a well-established manufacturing infrastructure, and a skilled workforce, all of which contribute to cost-effective production. Moreover, continuous research and development efforts have enabled Chinese suppliers to improve the quality and variety of their HPMC products, catering to diverse customer needs.
  • Beyond pharmaceuticals, HPMC finds applications in food, cosmetics, and construction industries. In food, it is used as a thickener and stabilizer, while in cosmetics, it acts as a film-forming agent in skincare products. In construction, it is incorporated into mortar and plaster to improve workability and set time.
  • In the food industry, HPMC is commonly used as a thickener, stabilizer, and emulsifier in various products. It can improve the texture and mouthfeel of foods, as well as prevent separation of ingredients in processed foods. HPMC is often used in dairy products, sauces, dressings, and bakery items to enhance their overall quality

    hpmc uses. Its water-holding properties also make it a valuable ingredient in gluten-free baking, where it can help improve the texture and shelf-life of gluten-free products.
  • In the pharmaceutical industry, HPMC is used as a binder and film former in tablets and capsules
  • Acetone and ethyl acetate, being polar aprotic solvents, can dissolve HPMC effectively due to their ability to disrupt the intermolecular forces within the polymer structurehpmc solubility in organic solvents. The solubility in these solvents increases with an increase in temperature, following the general rule of thermodynamics for solute-solvent interactions.
  • What do I need to tell my doctor BEFORE I take Hydroxypropyl Methylcellulose?

  • Beyond these applications, HPMC is also employed in paints, adhesives, and printing inks, demonstrating its versatility and adaptability to different industries. The precise manipulation of hydroxypropyl% and methyl% allows manufacturers to tailor HPMC's properties to meet the specific requirements of each application.

  • In the pharmaceutical sector, HEC serves as a binder, disintegrant, and viscosity enhancer in tablet formulationshydroxyéthyl cellulose. It is also used in ophthalmic solutions due to its non-irritating nature and ability to form gels.
  • Benefits of Using HPMC
  • Cosmetics and personal care products also heavily rely on HEC for its thickening and stabilizing effects. In shampoos, lotions, and creams, HEC ensures a pleasant, non-greasy texture while maintaining the product's homogeneity. Its film-forming property is particularly beneficial in hair styling products, where it helps to hold the style without leaving a sticky or tacky residue.
  • China, known for its vast industrial capabilities and innovative prowess, has emerged as a significant producer of redispersible powder, an essential ingredient in the global construction materials sector. Redispersible powder, also known as RDP, is a key component in various building applications due to its ability to enhance the properties of mortars and plasters.
  • Redispersible polymer powders are typically produced through a process called spray-drying. In this process, a liquid polymer solution is atomized into fine droplets and dried under controlled conditions, resulting in a fine, free-flowing powder. The choice of polymer type, as well as the drying conditions, significantly influences the properties of the final product.

  • In conclusion, HPMC's water solubility is a defining characteristic that contributes to its extensive use across diverse sectors. It is a testament to the power of chemical modification in tailoring the properties of natural polymers to meet specific industrial needs. Understanding and harnessing this property is essential for effective utilization of HPMC in various formulations and processes.

  • 11. What is related to the gel temperature of hydroxypropyl methyl cellulose?

  • In the pharmaceutical industry, HPMC is used as a binder, film former, and viscosifier in tablets, capsules, and ointments. The grade of HPMC used in pharmaceutical applications is usually of high purity to meet strict regulatory standards. HPMC helps control the release of active ingredients, improve drug solubility, and provide a smooth texture to the final product.
  • In addition to its many uses in the food industry, HPMC is also used in many other areas. For example, in the building materials industry to regulate flow properties, in the production of cosmetics such as toothpaste, shampoo, soap, cream and lotion and in the pharmaceutical industry as a component of medicines.

  • Hydroxypropyl methyl cellulose (E 464) is currently authorised as a feed additive for all animal species, without a minimum and a maximum content. It is also authorised, quantum satis, for use as a food additive.


  • Overall, VAE powder is a versatile and beneficial supplement that can be easily added to your daily routine. Whether you are looking to fill in nutritional gaps, boost your antioxidant intake, reduce inflammation, or support weight management, VAE powder has something to offer.
  • In addition to its thickening properties, HPMC dispersion is also a commonly used film-forming agent. When applied to a surface, HPMC forms a thin, transparent film that can provide protection or improve the appearance of the product. This makes it a valuable ingredient in products such as coatings or paints.
  • In the cosmetics industry, HPMC is a common ingredient in skincare, haircare, and personal care products. It is used as a film former, binder, and moisturizer in creams, lotions, and gels. HPMC helps improve the stability and texture of cosmetic formulations, providing a smooth and silky feel upon application. Its ability to form a protective barrier on the skin and hair surface helps retain moisture and prevent dehydration. Additionally, HPMC is easily emulsified with other cosmetic ingredients, contributing to the overall effectiveness of the product.
  • Hydroxypropyl methyl cellulose (HPMC) is an essential chemical compound that finds extensive use in a broad range of industries, including construction, pharmaceuticals, food, and cosmetics. It is a non-ionic, water-soluble polymer derived from natural cellulose through a process involving chemical modification. The term HPMC stands for the chemical composition of this substance, which is a combination of hydroxypropyl and methyl groups attached to the cellulose backbone.
