High Viscosity Type, Quick Dissolving Type Hydroxypropyl Methylcellulose For Building Materials
HPMC(Hydroxypropyl methylcellulose)- Introduction
HPMC, a non-ionic cellulose mixed derived from the modification of natural cellulose, appears as white or off-white powder with non-toxic and odorless properties, which dissolves in cold water to form a transparent colloid. Its core functions include thickening, water retention, film-forming, bonding and stabilization.
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 (largest consumption):
Water retention agent, thickener and bonding agent for putty powder, mortar and tile adhesive, improving constructability and strength.
2. Pharmaceutical:
Coating material for tablets, sustained-release matrix material and capsule shell material, realizing controlled release and improving stability.
3. Food:
Thickener, emulsifier and stabilizer (INS/E464) used in baking, dairy products and sauces to delay aging and prevent ice crystal formation.
4. Coatings & Daily Chemicals:
Thickener and dispersant for water-based coatings, film-forming and thickening agent in cosmetics, improving texture and stability.
5. Industry:
Dispersant for PVC suspension polymerization, bonding agent for ceramics, coating agent for papermaking, textile size and so on.
Company Profile
The company independently manufactures integrated nail-fastening products and holds equity in ammonium carboxymethyl cellulose (CMC-NH4) production and marketing. It holds nearly 70% domestic market share in HPMC for automotive exhaust honeycomb ceramics.
