Salt-tolerant & Stable Strong Film-forming Property Hydroxypropyl Methylcellulose For Pesticides

HPMC(Hydroxypropyl methylcellulose)- Introduction

HPMC is a non-ionic cellulose mixed  produced by the  modification of natural cellulose. It presents as a white or off-white odorless powder, soluble in cold water to form a transparent and uniform colloid while insoluble in organic solvents such as ethanol. It integrates six core functions: thickening, water retention, film-forming, bonding, suspension and stabilization, and also features thermoreversible gelation (45-90℃), wide pH stability (3-13), salt and electrolyte resistance, excellent compatibility, eco-friendliness and non-toxicity. As a high-performance functional additive widely used in the industrial field, it is applied in construction materials, pharmaceuticals, food, pesticides, coatings, daily chemicals, PVC polymerization and other industries.

 1.  High water retention:

      Locks in water, extends construction time, and prevents cracking and insufficient strength, which is the core value in the construction field.

 2.  Thickening and suspension:

      Increases slurry viscosity, improves troweling performance, and prevents sedimentation and delamination.

 3.  Thermoreversible gelation:

      Gel formation at high temperature and recovery upon cooling, adaptable to process temperatures of different operations.

  4. Film-forming and bonding:

       Forms a transparent film after drying, enhancing adhesion and glossiness.

  5.  Chemical stability:

       Mold and enzyme resistance, facilitating storage and application.

HPMC(Hydroxypropyl methylcellulose)  Main Application Fields

 1. Construction Materials (Largest Consumption):

     High-viscosity grades act as water retention agents, thickeners and bonding agents in putty powder, mortar and tile adhesive, extending construction time, preventing cracking, and improving bonding strength and constructability.

 2. Pharmaceuticals:

     Low-viscosity grades are used as tablet coating materials, sustained-release matrices and capsule shell materials to realize controlled release, and enhance the stability and disintegration of preparations.

 3. Food (INS/E464):

     Served as a thickener, emulsifier and stabilizer in baking, dairy products and sauces, it delays food aging, prevents ice crystal formation and improves taste.

 4.  Pesticides:

      As a functional auxiliary for pesticide formulations, it leverages high suspension, strong film-forming and excellent dispersibility to improve the spreading and adhesion of pesticides on crops, achieve long-acting sustained release and reduce liquid medicine loss.

 5. Coatings & Daily Chemicals:

      Used as a thickener and dispersant for water-based coatings and a film-forming thickener in cosmetics, it improves the system stability and product texture.

6.  Industrial Manufacturing:

     Applied as a dispersant for PVC suspension polymerization, a bonding agent for ceramics, a coating agent for papermaking and a textile size, it enhances the stability of production processes and product quality.
