Hydroxypropyl Methyl Cellulose, abbreviated as HPMC, is a non-ionic cellulose ether refined from natural cotton linter through alkalization, etherification, washing and drying. As an indispensable thickening, water-retaining and bonding functional additive, it is widely used in building mortar, coatings, daily chemicals, pharmaceutical preparations, food processing and PVC plastics industries. It owns core advantages of excellent water retention, thickening, anti-sagging, environmental safety and high cost performance.
- Meticulous craftsmanship: Two production paths ensure controllable and traceable quality
- Conventional low-viscosity synthesis process
Natural cotton fiber is subjected to simple alkalization and one-step etherification, with short production flow and low manufacturing cost. Viscosity fluctuation range is relatively wide, suitable for ordinary putty, general interior wall coatings and low-demand industrial thickening scenarios with cost priority.
- Precision multi-stage etherification and purification
Adopt precise processes including constant-temperature alkalization, segmented etherification, multi-cycle deionized water washing, high-temperature drying and airflow ultrafine grinding. Recycled cotton fiber waste can be reused as raw materials to realize green recycling production. Finished high-purity HPMC features stable viscosity, low ash content, high transparency and excellent water retention performance, meeting strict standards of exterior thermal insulation mortar, food additives, pharmaceutical excipients and high-end water-based coatings.
- Core Features: Six Major Advantages Underpin "Abundant Value"
- Environmentally friendly and non-toxic, compliant and worry-free
Derived from natural plant fiber, free of heavy metals and harmful solvents, conform to EU REACH, RoHS, food and pharmaceutical national safety standards. Non-irritating to human body, applicable to food, medicine, cosmetics and indoor building materials.
- Weather-resistant and lightfast, long-lasting and stable
Excellent anti-ultraviolet and anti-aging performance, no degradation, discoloration or performance attenuation under long-term outdoor exposure. Maintain stable thickening and water retention effect under high temperature, humidity and alternating cold and hot environments.
- Acid and alkali resistant and corrosion resistant
Stable performance within wide pH range, compatible with cement, latex, resin and water-based solvent systems. Will not hydrolyze and fail under weak acid and weak alkali construction environment, the preferred additive for building anti-corrosion mortar.
- Outstanding water retention and anti-sagging thickening effect
Unique macromolecular network structure locks free water inside the system, effectively prevent rapid water loss of mortar and coatings, extend operable time; provide obvious anti-sagging and anti-sedimentation performance, small addition amount can significantly improve construction performance and reduce overall material cost.
- Good dispersibility and convenient construction
Uniform ultrafine powder, can be quickly dissolved in cold and hot water without agglomeration, adaptable to stirring, spraying, scraping and other construction processes of mortar, coatings and daily chemical products.
- Batch stability and controllable quality
Formal manufacturers implement ISO9001 quality management system, strictly control viscosity, ash content, water retention rate and dissolution speed of each batch, avoid construction cracking, sagging and other losses caused by unstable additive performance.
- Empowering all industries: From basic building materials to high-end manufacturing, covering all sectors
- Building Materials Industry
Interior and exterior wall putty, thermal insulation mortar, tile adhesive: strong water retention, prolong opening time, prevent hollowing and cracking;Water-based architectural coatings, self-leveling mortar: thickening anti-sagging, uniform texture and stable storage.
- Daily Chemical and Food Pharmaceutical Industry
Shampoo, body wash, facial mask: thickening and film-forming, mild and skin-friendly;Tablet binder, food thickener: safe and tasteless, improve molding and mouthfeel.
- Plastic and Industrial Coating Field
PVC plastic processing auxiliary: lubrication and dispersion, improve product surface smoothness;Water-based industrial anti-corrosion paint: anti-sedimentation, extend paint storage life.
