1. Product Introduction & Main Application
Arnico’s Polyol is a polyether resin with multiple hydroxyl groups and a controlled molecular weight, serving as the primary alcohol-side raw material in the production of polyurethane (PU) foams. This foundational product plays a crucial role in determining the density, flexibility, and mechanical properties of both rigid and flexible foams for the construction, automotive, and refrigeration industries.

3. Features & Benefits
-
Excellent Thermal & Hydrolytic Stability: The final foam exhibits high resistance to degradation in high-temperature and high-humidity environments.
-
Consistent Reactivity: Precise molecular engineering ensures a controlled foaming reaction, free from irregular cell structures or voids.
-
Optimized Flowability: Ideal viscosity for completely filling complex molds before the gel stage is reached.
-
Blowing Agent Compatibility: Excellent miscibility with a wide range of physical (HCFC/HFC) and chemical (water) blowing agents to achieve target densities.
4. Industrial Applications
-
Building Insulation: Production of rigid polyurethane foam for sandwich panels and spray-applied roof and wall insulation.
-
Refrigeration Industry: The primary insulating material in the manufacture of domestic refrigerators, industrial freezers, and cold storage facilities.
-
Furniture & Mattresses: The key raw material for molded and slabstock flexible foams used in comfort furniture and orthopedic mattresses.
-
Automotive Industry: Production of seat cushions, headrests, steering wheels, and acoustic insulation components.
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): This substance generally has low acute toxicity but may produce irritating vapors at high temperatures. Please refer to the Arnico MSDS for complete information.
-
Storage Conditions: Store in tightly closed, completely dry containers, away from moisture and heat sources, at a temperature of +10°C to +30°C. Water ingress must be strictly prevented (risk of decomposition upon prolonged contact with moisture).
-
Personal Protective Equipment (PPE): Use of local exhaust ventilation, safety goggles, and chemical-resistant gloves (neoprene) is mandatory during sampling and decanting.
6. Quality Assurance & COA
Arnico Polyol shipments are always accompanied by a precise COA detailing the exact hydroxyl value range and molecular weight distribution curve. This allows foam formulators to easily calculate the correct stoichiometric ratios with isocyanate.
