All Products

  • Calcium Formate Calcium Formate
    Calcium Formate
    Brief: Calcium formate is a calcium salt commonly obtained by reacting calcium oxide or calcium hydroxide with formic acid. It appears as a white, crystalline powder that is highly soluble in water. This compound has a variety of uses in construction applications.
  • 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.

FAQ

  • Q Can you confirm that product quality remains consistent across different batches?

    A We strictly control our processes to ensure consistent product quality.
    We establish fixed quality standards for key raw materials and inspect them prior to warehousing to prevent raw material variations from affecting the final product.
    During production, we control parameters—such as reaction temperature, reaction time, concentration, drying conditions, and particle size—according to standardized procedures, while also conducting sampling and testing at critical production stages.
    Once a batch of finished product is completed, the laboratory tests key indicators against product specifications.
    Only products that meet the prescribed standards are approved for release.

  • Q What are the packaging and shipping specifications?

    A Packaging: 25 kg/bag.
    Pallet weight: 600 kg/pallet (24 bags).

  • Q Where can orders be placed for delivery?

    A Shipping range: Worldwide (sea, rail, road, and air freight).

  • Q What is the minimum order quantity (MOQ) for the product?

    A MOQ: 1,000 kg.

  • Q How to Determine Quality?

    A 1. Before the transaction, you can contact our sales representative to request a quality inspection report. Our company guarantees the authenticity of the data in the quality inspection report. If your testing results do not match the quality inspection report, we will unconditionally accept returns and provide a refund.
    2. Before the transaction, we can provide a small sample for testing (free samples are only available to customers with a genuine need; samples are generally provided to factories, but not to reagent companies).

HPMC Vs HEMC in Industrial Degreasers: Stability in High-Surfactant Loads

This article compares HPMC and HEMC for industrial degreasers operating under high-surfactant loads. It explains how cellulose ether selection affects viscosity stability, salt tolerance, surfactant compatibility, anti-settling behavior, vertical cling, thermal resistance, and product processing. HPMC is especially suitable for structured gels and cling-oriented degreasers, while HEMC is often preferred for concentrated, salt-containing, and high-active liquid cleaning formulations. The article also provides a practical testing method, common formulation mistakes, application examples, and guidance for selecting the right cellulose ether based on the complete degreaser formula.
