Light weight polyurethane foam boards are most favoured materials that designers prefer to work with to create shaped forms or styling prototypes/models. These specially formulated boards are offered from 0.08 to 0.35 g/cm³ density with optimum balanced mechanical and thermal properties. All boards feature excellent machinability by hand or CNC milling, producing mainly shavings and minimal dust while delivering a fine and non-powdery surface.

Medium density brown boards are the ideal material for making master models or molds for short series of parts. From 0.45 to 0.70 g/cm³ we offer a complete range to satisfy every preference of model makers in mechanical strength, thermal resistance and surface aspect. Prolab boards display the smoothest surface aspect in such category in the market place while SikaBlocks® are thermally the most resistant and stable.

For composites tooling we offer epoxy boards with very compact surface aspect, high dimensional stability under heat and pressure to produce prepreg moulds or parts in autoclave up to 130 °C. We offer medium to high density Polyurethane tooling boards from 1.0 to 1.7 g/cm³ with high mechanical strength and heat resistance up to 100 °C combined with high dimensional stability. Their performance package makes them suitable for applications such as checking fixtures, gauges, vacuum forming tools, low pressure RIM-molds as well as metal sheet stamping tools.

Sika offers a wide range of tooling boards specially dedicated to make foundry patterns and core boxes for coldbox. Model makers can select the most suitable board for their requirements in durability: abrasion resistance level from low to highter series of sand moldings to be made as well as strength and dimensional stability. These boards are cost effective alternative solutions to metallic patterns and core boxes for coldbox for most foundry processes up to medium size series.
