Refrigeration PUF Chemical is a premixed polyol formulation designed for use with MDI-based isocyanates to produce rigid polyurethane foam with low thermal conductivity, high closed-cell content, and excellent dimension stability.
It is optimized for refrigeration appliances, where insulation quality is critical for energy efficiency.

The blend typically contains:

• Polyether polyols (base component)

• Catalysts (amine/metal catalysts for controlled reaction)

• Surfactants (for cell structure stabilization)

• Blowing agent(s) (such as cyclopentane blends or alternatives depending on region)

• Additives (antioxidants, flame retardants depending on specification)

(Exact formulation varies by manufacturer.)

(Typical values—supplier-specific numbers may vary)

This chemical is tailored for polyurethane rigid foam used in:

• Domestic refrigerators & freezers

• Commercial deep freezers

• Cold-room sandwich panels

• Display cabinets

• Refrigerated transport units

• Insulated containers & iceboxes

The resulting foam provides:

• Low thermal conductivity (K-value)

• High compressive strength

• Fine closed-cell structure

• Low foam density (28–45 kg/m³ typical in refrigeration)

• High insulation performance for energy-efficient refrigeration

• Produces uniform, closed-cell rigid foam

• Balanced catalyst system for stable processing

• Compatible with MDI-based isocyanates (typically polymeric MDI)

• Suitable for manual and machine foaming

• Good dimensional stability under thermal cycling

• Store in dry, sealed containers to avoid moisture absorption.

• Ideal storage temperature: 20–25 °C (varies by manufacturer).

• Avoid contact with water — polyols react with moisture.

• Drums should be kept away from direct heat/sunlight.

Product Type: Polyether Polyol (PU Component – “B-component”)
Packaging: 200 L drum (approx. 200–220 kg depending on density)
Appearance: Opaque white or milky white viscous liquid
Primary Use: Raw material for polyurethane (PU) production—rigid, semi-rigid, or flexible foam depending on grade.

White Polyol Chemical is a polyether polyol blend designed for use with MDI-based isocyanates to create polyurethane foam or elastomeric materials.
The “white” appearance typically comes from:

• A base polyether polyol

• Surfactants

• Catalysts

• Additives (antifoam, stabilizers, flame retardants depending on grade)

The color does not affect reactivity; it is simply characteristic of many formulated polyol blends supplied for industrial PU manufacturing.

(Generalized values — may differ by supplier and application type)

Different sub-types exist (rigid foam polyol, flexible foam polyol, elastomer polyol, etc.), each with different OH values and viscosities.

White Polyol Chemical is used to produce polyurethane materials in:

• Refrigeration & insulation foams

• Construction panels

• Flexible PU foam (cushions, bedding, furniture)

• Elastomeric PU parts

• PU adhesives and sealants

• Footwear and molding applications

Depending on the polyol design, it can be used for rigid, semi-rigid, or flexible PU systems.

• Stable, consistent polyether polyol formulation

• Good compatibility with polymeric MDI

• Designed for smooth and uniform foam cell structure

• Low moisture for controlled reaction behavior

• Suitable for both manual mixing and PU foam machines

• Provides balanced mechanical and thermal properties in finished PU

• Keep in dry, sealed 200 L drums to avoid moisture contamination.

• Store between 20–25 °C away from heat or sunlight.

• Mild settling of additives may occur in some blends; gentle mixing is normally recommended by suppliers.

• Moisture contact should be avoided as it affects polyurethane reactions.

Product Name: Polyol CP 2100
Chemical Type: Polyether Polyol (typically a tri-functional polyether polyol)
Appearance: Clear to slightly pale-yellow viscous liquid
Odor: Mild, characteristic polyol odor
Primary Use: Component for polyurethane (PU) systems — especially cast PU elastomers, CPU/TPU prepolymers, and coatings or adhesive systems.

Polyol CP 2100 is a polyether-based polyol designed to react with isocyanates (such as MDI/TDI) to form polyurethane elastomers.
It typically provides:

• Medium-to-high molecular weight

• Triol functionality (≈3 reactive OH groups per molecule)

• Moderate OH value suitable for elastomeric PU formulations

• Good balance of viscosity and reactivity for casting applications

(Values are representative of CP-series 2000-range polyether polyols; exact numbers depend on manufacturer.)

These values make it suitable for producing elastomers with excellent mechanical strength, elongation, and abrasion resistance.

Polyol CP 2100 is commonly used in:

• CPU (Cast Polyurethane) elastomers

• TPU / CPU prepolymers

• Polyurethane coatings & sealants

• Industrial rollers, wheels, bushings

• Low acidity and low moisture for consistent reaction behavior

• Suitable for manual or machine casting

(Non-instructional)

• Store in a dry, sealed container to avoid moisture contamination.

• Keep away from direct sunlight and extreme temperatures.

• Typical shelf life: 12 months under proper storage (supplier dependent).
