Frequently Asked Questions

What is a Polyester Polyol?

Polyester Polyols are synthetic resins made by reacting dicarboxylic acids and dihydric alcohols. They are characterised by a high molecular weight and are used in the production of polyurethanes. Polyols are versatile and can be customised for to meet the specific needs of the end application.

What are the advantages of using Polyester Polyols?

Polyester Polyols have four primary applications, each with their own diverse set of benefits.

Polyurethane Coatings are noted for their toughness, chemical and abrasion resistance. They can provide a high gloss finish and come in different levels of flexibility that allow them to give protection to concrete, metal, timber and plastic. Used in outside applications, the coatings have outstanding weathering characteristics.

Polyurethane Foams are suitable for both sound proofing and insulating buildings due to their honeycomb structure. Other applications include surfboard blanks and buffing pads. The foams possess strong resistance to oils making them ideal for applications like oil filters.

Cast Polyurethanes come in a wide hardness range with excellent resistance to abrasion and good resistance to impact. Their high rebound recovery makes cast polyurethanes the material of choice for skateboard wheels.

Thermoplastic Polyurethanes are similar to cast urethanes but require heat to be formed into finished goods. Thermoplastic Polyurethanes are ideal where high volumes of parts need to be made. Being a thermoplastic, they are able to be re-processed.

What are some common uses of Polyester Polyols?

Polyester Polyols come in a variety of forms including liquids at room temperature, waxy solids, crystalline solids and solvent cut. These different forms allow the Polyols to be utilised in a number of applications, most commonly:

• Castable elastomers eg. printing rollers
• Surface and fabric coatings
• Microcellular shoe systems
• Inks
• Industrial coatings
