Double-ended studs are commonly used in automotive and industrial applications. In the automotive industry, they are often used to secure engine components, exhaust systems, and other parts that need to be securely fastened together. In the industrial sector, double-ended studs are used in machinery, equipment, and structural applications
- HPMC stands for Hydroxypropyl Methylcellulose, a chemical compound widely utilized in various industries due to its unique properties and versatile applications. It is a semi-synthetic polymer derived from cellulose, a natural polymer found abundantly in plant cell walls.
- Primarily, redispersible polymer powder is widely used in the construction industry as a binding agent. It enhances the adhesive strength and flexibility of mortar, making it ideal for applications like tile setting, dry mix mortars, and repair compounds. Its ability to improve the workability, water resistance, and cohesion of these materials significantly increases their durability and performance.
- In the construction industry, HPMC is a key component in dry mix mortars, providing improved workability, cohesion, and water retention. Its use enhances the quality and durability of building materials, reducing costs associated with frequent maintenance. For those looking to purchase HPMC for construction applications, our products guarantee superior performance and consistent results.
- After spray-drying, the polymer particles are often coated with a protective layer to enhance their stability and redispersibility
- Hydroxypropyl methylcellulose, commonly abbreviated as HPMC, is a versatile pharmaceutical excipient that has become indispensable in modern formulation science. This synthetically modified cellulose derivative exhibits unique properties that make it an ideal choice for a variety of applications in the pharmaceutical industry, including its use as a binder, disintegrant, thickener, and stabilizer.
Interactions with other ingredients:
- In the pharmaceutical industry, HPMC is used as a binder, disintegrant, and coating agent in tablets and capsules. It helps to improve the flowability and compressibility of powders, making them easier to process into solid dosage forms. HPMC also acts as a protective coating, protecting the drug from moisture and degradation, and controlling the release rate of the active ingredient.
The Difference between Methyl Cellulose and HPMC
- In conclusion, the viscosity-concentration relationship of hydroxyethyl cellulose plays a pivotal role in determining its utility across diverse industries. Careful consideration and optimization of these parameters ensure the desired performance characteristics are achieved, making HEC a highly adaptable and valuable ingredient. Understanding and controlling this relationship is crucial for effective formulation development and process optimization.
- In tablet formulations, HPMC acts as a binder, enhancing the tablet's mechanical strength and ensuring uniformity in drug content. It helps in the wetting and disintegration process, allowing tablets to dissolve efficiently in the gastrointestinal tract. For instance, in immediate-release formulations, HPMC contributes to the rapid disintegration and dissolution of the drug, ensuring a quick onset of action.
Hydroxypropyl Methylcellulose (HMPC) is a polysaccharide additive used in frosting, coatings, gluten-free baking and dietary supplements. It is also a stabilizer, thickener, fat replacer, bulking and binding agent. 1


What is this drug used for?
The applicant claims that the feed additive HPMC is specified to be manufactured to meet the specifications set for its use as a food additive. The main specifications as food and feed additive are: methoxyl groups ≥ 19 and ≤ 30%, hydroxypropoxyl groups ≥ 3 and ≤ 12%, loss on drying < 10%, sulfated ash < 1.5% (for products with viscosities of 50 mPa.s or above) or < 3% (for products with viscosities below 50 mPa.s). Five batches of the additive were analysed for some of the above specifications, resulting in: methoxyl groups (four batches) 23.5–29.2%, hydroxypropoxyl groups (four batches) 5.2–8.4%, loss on drying (one batch) 1.2% and sulfated ash (one batch) 0.6%. Only statements, without figures, of compliance with the specifications for some impurities (heavy metals, arsenic, solvents, microbial purity) were provided. Information on other impurities ((pesticides, dioxins, dioxin-like and non-dioxin-like polychlorinated biphenyls, mycotoxins, botanical impurities) was not provided.
Hydroxypropyl methylcellulose cannot be digested by humans and passes through the digestive system.
