All Products

  • Hydroxyethyl Methyl Cellulose - HPMC
    Hydroxypropyl Methyl Cellulose - HPMC
    Brief: Appearance – product is a white or off-white powder, odorless and non-toxic. It can form a transparent colloid in aqueous solution.

    Our construction grade HPMC mainly suitable for: tile adhesive factories , putty powder factories, plaster factories , dry mix mortar factory, paint factory etc.

    Hydroxypropyl methyl cellulose is produced by selecting highly pure cotton fiber as raw material and specially etherifying it under alkaline conditions. It has the characteristics of thickening ability, salt resistance, low ash content, PH stability, water retention, excellent film-forming properties, and extensive mildew resistance, dispersion and adhesion.
  • Hydroxyethyl Cellulose - HEC
    Hydroxyethyl Cellulose - HEC
    Brief: Our Hydroxyethyl Cellulose Ether (HEC) products are divided into two major categories: construction-grade and daily-chemical-grade. In order to better serve our customers across various projects, we have conducted in-depth research and development on our construction-grade HEMC. This has led to the production of specialized cellulose ether variants for applications such as putty, mortar, tile adhesive, gypsum Etc.
    Furthermore, we leverage the advantages of our manufacturing facilities. We can customize the production of methylcellulose ethers based on your geographical location, construction environment, and specific application requirements.
    If you are looking to buy HEC, you can discuss it with our experts, then to get a better solution before buying. We provide free samples for testing.
  • Hydroxyethyl Methyl Cellulose - HEMC
    Hydroxyethyl Methyl Cellulose - HEMC
    Brief: Hydroxyethyl methyl cellulose is a water-soluble cellulose mixed ether that has the properties of both CMC and HEC. It has high hydration binding capacity and good flocculation on suspended solids. In addition, hydroxyethyl methylcellulose also has the functions of thickening, adhesion, emulsification, film formation, suspension, dispersion, water retention and providing protective colloid. It is soluble in hot or cold water, does not precipitate at high temperatures or boiling, and has a wide range of solubility. Hydroxyethyl methyl cellulose contains hydroxyethyl groups, so it has good anti-fungal ability. It has good viscosity stability and anti-fungal degeneration during long-term storage.
  • 20+ Years of Production Experience
    Decades of specialized experience in cellulose ether development and manufacturing.
  • Advanced German Production Lines
    We use imported automated equipment to ensure accuracy, consistency, and efficiency.
  • Independent In-House Testing
    Each batch is rigorously tested by professional technicians to ensure product quality and consistency.
