We create polyurethane boards in a range of sizes and densities used in
model construction, tool making and mould production

Polyurethane boards

Ru-bix offers a range of polyurethane styling, modelling and tooling boards, suitable for demanding applications in the engineering sector. We supply the automotive, aerospace, marine, rail, foundry, signage and other industries where prototyping and modelling
work is required. Our standard range of products consist of polyurethane boards with densities ranging from 30kg/cub.m to 1220kg/cub.m. Available in standard sizes of 1500mm x 500mm x (30, 50, 75, 100, 150 and 200mm thickness), it is possible to meet the specific demands of most model or mould-making projects.

Dimensional stability

Boards maintain dimensions when subjected to changes in temperature
and humidity.

Mechanical strength

An optimised combination of low density and high mechanical properties, particularly compressive and flexural strength.

Superior surface finish

Inherent fine cell structure and low friability that facilitates bonding
without pre-treatment.

Not all boards are created equal

At Ru-bix we pride ourselves on providing customers with a bespoke service quite unlike any

Our bespoke polyurethane tooling boards can be provided at very competitive prices, ensuring
that customers benefit fully in terms of working efficiency, with reduced costs and marginal
levels of waste.

 Low density 

For styling applications

Versatile and lightweight, our styling boards are semi-finished products which can be bonded into various shapes and sizes.

The styling and design portfolio are natural coloured which are favoured in the market.

RX-30   30 kg/m



RX-80   80 kg/m

Lightweight with smooth surface and low dust formation for design research applications


RX-150   150 kg/m

Fine, non-powdery surface suitable for milling in design studies

Very light weight with fine cell structure for master models and patterns

RX-200   200 kg/m


Easily machined with very good surface structure. Particularly suitable for master models


RX-300   300 kg/m

Very smooth surface for some master models and vac-forming applications

 Higher density 

Modelling boards & tooling boards

Higher density modelling and tooling boards are easy to machine, hard wearing and long lasting. 


Modelling boards are often used for vacuum forming, model making and prototyping.

The highest density tooling boards are used where manufacturing stresses are high, or where exact dimensional tolerances, sharp-corner retention and excellent surface finish are important.

RX-600   600 kg/m


Good dimensional stability and low CTE for master models and vac-forming models


RX-700   700 kg/m

High mechanical properties and low CTE for master models and foundry patterns

RX-1200  1200 kg/m


High strength, easily machined, capable of high-gloss finish. Ideal for foundry models and hammer form tools

Need adhesives too?

We provide adhesives matched to the hardness and colour of the boards for bonding. We offer both single and two-component adhesives to support our tooling board customers.
