Our Polyurethane Selection Guide will help you discover the large range of polyurethane systems we supply, and figure out which product is best suited for you. Our Polyurethane products are broken down into 4 categories – Rigid, Flexible, Expanding Foam, and Water Clear. We explore each group and the features that differentiate the various systems, plus tips and tricks on getting the most from your polyurethane product. For the best results, please use a vacuum degasser with rigid and elastomer polyurethanes to remove air from your mixture.
Rigid Polyurethanes - Aromatic
Our Rigid Aromatic polyurethanes are the most common type of casting PU, as they are generally more economical, offer good physical properties, and come in both rigid and elastomeric formulations. However, Aromatic resins can have poor UV and chemical resistance. If colour stability and resistance to environmental oxidation are important, consider using our UV Additive.

FLEXIBLE POLYURETHANES
The following products can be broken down into three groups – The F-series, CF range and Flexicast systems.
- The F Series offers a Fast work time and Fast cure time, predominantly used for casting parts and have excellent physical properties.
- The CF range stands for Colour Flex, which may take on the true tones of a pigment if colour is an important feature. These are also primarily used for creating cast parts.
- And finally, the FLEXICAST range was designed for making high strength moulding rubbers for casting concrete, plasters and waxes. They may also be used to cast parts, but check the specs to see if an F series or CF product may be better suited.

Expanding Foams
The foams may be easily navigated by name and number. The S is for Soft, and the R is for Rigid. The number indicates density, so the lower the number the lighter the foam, and the greater the expansion. Please use a wax based release agent like MACWAX or Challenge 95 with the foams, and AVOID silicone based release agents. Read the TDS for further information.

Water Clear Aliphatic Polyurethanes
Our Water Clear Polyurethanes are available in both rigid (Shore D) and flexible (Shore A) formulas. The Aliphatic polyurethanes can exhibit great UV & colour stability, and chemical resistance. Their downside is typically longer work times and de-mould times, low heat distortion, low tolerance to colder casting temperatures, and higher material costs.
