Our Products

Polyol and isocyanate for PU foam

The two key raw materials for flexible polyurethane foam — polyol and TDI 80/20 isocyanate — supplied to industries across Thailand.

Product 01

Polyol

Description

Polyol for flexible polyurethane foam is a polymer component specifically designed for the production of flexible polyurethane foams. This versatile material is a key ingredient in creating soft, durable, and resilient foam products that offer superior performance across various industries. With its customizable formulations, polyol ensures optimal properties like density, elasticity, and comfort in the end product.

Applications

Polyol for flexible foam finds applications in a wide range of industries due to its adaptability and superior performance characteristics:

  • Furniture and Bedding
  • Automotive Industry
  • Packaging
  • Cleaning Sponge
  • Others

Typical properties only; not to be construed as sales specifications. All grades: protect from atmospheric moisture, store in a dry place and avoid prolonged exposure to heat and air.

What do these values mean?
  • Molecular weight — the size of the polyol molecule. Larger molecules generally give softer, more elastic foam.
  • Hydroxyl number — how many reactive OH groups the polyol carries; it sets how much isocyanate the formulation needs. A lower number means a larger molecule.
  • Viscosity — how thick the liquid is, which affects pumping and mixing.
  • Water — moisture content. Low, consistent water keeps foaming predictable.
  • Color (APHA) — how clear and colourless the liquid is; lower is clearer.

Product 02

Isocyanate TDI 80/20

Description

Isocyanate for polyurethane (PU) foam is a critical component in the production of polyurethane foams, offering superior strength, durability, and versatility. Our isocyanates are specially engineered to work in synergy with polyols, enabling the creation of foams with exceptional properties such as flexibility and resilience.

With a focus on quality and sustainability, our isocyanates are manufactured to the highest industry standards. They provide reliable performance, fast reaction times, and consistent quality in the production process. Additionally, they are compatible with a wide range of formulations, including those with flame-retardant or environmentally friendly additives.

Typical properties only; not to be construed as sales specifications.

What do these values mean?
  • Purity — share of the drum that is TDI itself. Higher purity gives more consistent reactions.
  • Hydrolyzable chlorine — trace impurity that slows the foaming reaction; lower is better.
  • 2,4-isomer ratio — TDI 80/20 is about 80% 2,4-isomer and 20% 2,6-isomer, the standard blend for flexible foam.
Safety notice — TDI is a hazardous chemical
  • GHS signal word: Danger. Fatal if inhaled. May cause allergy or asthma symptoms or breathing difficulties if inhaled, and may cause an allergic skin reaction. Causes skin and serious eye irritation.
  • Reacts with water, releasing carbon dioxide that can pressurize and rupture closed containers. Keep away from moisture, amines, alcohols, bases and oxidizers.
  • Freezes at about 12 °C — avoid storing below this temperature.
  • Handle only in well-ventilated areas with suitable respiratory, eye and skin protection. Store locked up in a dry, fire-resistant area.
  • Regulated for transport: UN 2078, Class 6.1, Packing Group II.

Read the full Safety Data Sheet before handling. It is available to customers on request.
