Shipping Information

This product listed to by in a range of sizes. One or more larger sizes are classed as 'oversize' for delivery to some international destinations which means that delivery might not be available to some countries or when combined with certain types of product (dangerous goods for example).

When checking the delivery cost of your order, if you receive an 'oversize' warning then you may need to select a smaller size of this product in order to continue. Alternatively, please contact us to discuss.

PF90 High Density Polyurethane Foam

90kg/m³ polyurethane (PU) foam block ideal for composite pattern making. This high density foam can be used to produce sturdier, more detailed patterns. It can still be cut and shaped by hand but is also well suited to CNC machining. Also suitable for use as a buoyancy foam or non-structural core material.

The foam is 100mm thick and available to buy online in a range of block sizes from 300 x 300mm to 1220 x 1220mm.

High density PU foam block ideal for making sturdy patterns with precise surface detail and a high quality surface finish.

Our High Density Polyurethane Foam Block has a nominal density of 96kg/m³. Also available is our Low Density Polyurethane Foam Block with a nominal density of just 48kg/m³.

Advantages

Perfect for large patterns and fast hand working:

  • Can be cut and shaped by hand or machined.
  • High density results in sturdy, durable patterns (which can be walked on).
  • Dimensionally stable (will not expand or contract).
  • Compatible with epoxy, polyester and vinylester resin systems.
  • Can be finished to a high standard with a range of surface coats.

How to Use

Our High Density Polyurethane Foam Block is available in block sizes of: 600x600mm, 600x1200mm and 1200x1200mm. Please choose the block size you require from the drop-down list.

Multiple blocks of foam can easily be bonded together to create very large patterns (full vehicle bodies, for example).

Further Information

Marine Use / Core Material Use

As well as use as a pattern making foam block this High Density Polyurethane Foam Block is also intended for use (and approved for use) as a structural core material. Core materials can be used in GRP structures to increase stiffness for load bearing purposes, reducing weight, cost and laminating time.

Our High Density Polyurethane Foam Block carries Lloyds approval as a rigid core material for marine use making it also ideally suited for use as a composites core material in applications like boat decks and bulkheads where lightness, low resin uptake and cost are important factors.

Lloyds Registry of Shipping Approved Certificate of Acceptance No. YSL/SA/019 (for yachts up to 45' in length).

It's completely rigid. If it is 'hit' it will dent and stay dented. The way to think of this type of foam that helps people the most is that it's similar to (albeit higher density and therefore stronger) Oasis - the type of foam used for dried flower arranging. Therefore, although it would absorb impact from a shock, it would deform and stay deformed.

Our Pattern Coat Primer product is excellent for sealing foam and lower density modelboards. On lower density foams you might also choose to use a scrim of glass cloth to add some more strength to your pattern first. When using the Pattern Coat Primer, a typical thickness would be around 0.5mm.

No, it's expanded polystyrene foam (like styrofoam/blue foam) that you can cut with a hot-wire cutter. To cut PU foam you will need a blade of some description.

Polyurethane is a highly chemically inert material meaning that the vast majority of solvents and household chemicals will not dissolve the PU foam at all.

We are not aware of any easily available solvents or relatively safe to use chemicals that will dissolve the PU foam. If you did need a foam that is more readily dissolved then expanded polystyrene (EPS) such as Styrofoam might make a better choice.

Although perfectly possible to cut the Low Density Foam by water jet, it is more common to use other more simple manual methods. But for more precise applications, the foam works well with all CNC cutting and routing operations where the foam can be easily machined to a shape or pattern

This PU foam is a 'closed cell' foam and so if the foam was exposed there would not really be any water uptake in the short to medium term. For example, if you submerged a block of this foam in water for a number of hours and then removed it, there would be almost no measureable water uptake. If the damage was left unrepaired in the very long-term then water ingress into the damaged laminate along with pooled water in the damaged area would eventually start to deteriorate the foam and surrounding laminate so it is certainly advisable to repair any such damage correctly within a reasonable timeframe.

Yes, our High Density Polyurethane Foam Block is suitable (and approved) for use as a structural core material.

Our High Density Polyurethane Foam Block carries Lloyds approval as a rigid core material for marine use making it also ideally suited for use as a composites core material where lightness, low resin uptake and cost are important factors.

Another product worth consideration for the same application would be our EasyCell75 Closed Cell PVC Foam. The EasyCell is a bit more practical for thinner boards as it is available in a number of thicknesses ranging from 3mm to 25mm and thus would need less machining and have less waste. It also has a slightly finer cell structure which means less resin uptake at the bond-line.

The PU90 has a heat distortion temperature of 75C which would make it unsuitable for many vacuum forming processes due to heat. Also in its natural state, it has a matt finish, which we have found in testing, is very difficult get a good release from meaning that the part may well stick to the mould or damage the mould during the release.

A better product would be our Vac Cast Epoxy Casting Resin which is an aluminium filled and stabilised epoxy based casting resin ideal for vacuum forming tools.

Although it is technically possible to make a surf board from this foam, we would not recommend it.

This foam is primarily designed for pattern making applications meaning it is more rigid than a typical surfboard so would not provide the same kind of flex. It would also be more vulnerable to fracture and hence not as durable in a practical sense

No, this foam is not rated for fire protection.

No, I don't think so. I'm not too familiar with the type of foam used for a gymnasts mushroom but I would expect it's a 'spongy' foam that would spring back into shape (more like what would be used in furniture padding) whereas this foam block, if dented, will stay dented (like the dry flower arranging foam Oasis).
