High Load Bearing (HLB)
Sheets of Polyurethane foam are just one of hundreds of products supplied by Advanced Seals & Gaskets Ltd, available in various grades, including our high load bearing foam sheets.
Polyurethane foams are one of the more commonly used materials found in everyday applications including furniture and car interiors. High load bearing PU raw material foams are manufactured in master buns or blocks around 2.3m x 2m or 2.3m x 1m in size, which can then be split into sheets in thicknesses starting from around 1.5mm using one of our state of the art splitters - which is in theory a giant industrial peeler, which can be pre-programmed and set to peel off layers of foam and thus resulting in rolls of material in the desired thickness.
These sheets can be supplied in full, or further cut and converted in a choice of finished components including washers, gaskets, fabrications and strips using a choice of one of our many conversion presses, saws and routing machines.
Why Use High Load Bearing Foam Sheets?
Sheets of HLB foams are popular due to their load bearing properties and the resistance to impact and force they offer. As with other Polyurethane foams, high load bearing foam sheets can be manufactured in various densities and also grades to include Flame Resistance properties.
High density Polyurethane foams are popular and commonly known for their ‘viscoelastic’ properties - i.e the materials resistance and recovery after force has been applied. Although HLB foams can be manufactured in varying densities and levels of firmness, hybrid foams can also be made by laminating sheets of HLB foam with other lower density materials, which allows manufacturers to be able to offer bespoke levels of firmness to suit every need.
Just a few uses of high load bearing foams include Mattresses, boat seats, campaign mats, pet bedding, sports mats and packaging.

High-load bearing foam sheets excel at distributing weight evenly. This is particularly beneficial in applications where there are heavy loads or pressure points, such as in industrial equipment, packaging, or under flooring.
These foam sheets provide structural support and help prevent deflection or deformation under heavy loads. This makes them suitable for use in construction, manufacturing, and other industries where structural integrity is essential.
High-density foam sheets offer enhanced impact resistance. This is valuable in applications where the material may be subject to heavy impacts, shocks, or vibrations, providing protection to delicate or sensitive equipment.
The high-density nature of these foam sheets contributes to their durability. They are less prone to wear and tear, making them suitable for long-term and heavy-duty applications without significant loss of performance.
These foam sheets provide structural support and help prevent deflection or deformation under heavy loads. This makes them suitable for use in construction, manufacturing, and other industries where structural integrity is essential.
The dense structure of these foam sheets makes them effective in dampening vibrations. This is useful in applications where minimizing vibration is important, such as in machinery or transportation equipment.

What are High Load Bearing Foam Sheets?
Raw material HLB PU foams are manufactured in master blocks around 2.3m x 2m or 2.3m x 1m in size, these blocks are fed through one of our state of the art splitters, which work by setting the blade to peel off the desired thickness of foam which is then hand rolled by the operator around core until the full length of material is done.
As with other Polyurethane foams, high density polyurethane foam is generally made from two ingredients: polyol, which is petroleum-based, and diisocyanate - these two ingredients make up the basis of polyurethane foams. Components cut from HLB sheets of material are used across many industries. High density PU is a very dense foam which offers excellent support and shock absorption. Not only is this material found used widely within the furniture and automotive interior industries, it is also used for packaging and transporting fragile components within the electronics market due to the high level of protection the foam provides.
High load bearing foam sheets (HLB) are of particular interest to the electronics market where cushioning fragile components is key. HLB foam sheets can be manufactured in varying firmness levels (this firmness isn’t to be confused with density) for use in different applications and industries which require different levels of support.
Benefits of using High Load Bearing Polyurethane Foam
- Durable and Study
- Excellent levels of viscoelasticity and recovery
- Available in many sheet sizes
- Can be laminated to other materials
- FR and Anti-Static grades available
- Easy to cut
Advantages of using High Load Bearing Polyurethane Foam Sheets
HLB foam sheets are made from master buns of material, therefore they can be made in bespoke sheet sizes, thicknesses and finishes. High load bearing PU foams are not only found used in the production of mechanical and engineering components, but also in many commercial and residential seating applications - often used as a replacement for spring systems offering higher levels of stability and comfort when used for seating and bedding.
Due to their excellent viscoelastic properties, they are also great for use in automotive applications as interior fillings, industrial applications such as buffer or impact pads or as seals and gaskets. When used for packaging and transporting fragile components within the electronics market, they offer a high level of protection and cushioning delicate items.
High load bearing PU is available in a choice of densities and thicknesses, but can also be laminated to other materials to offer rolls in bespoke levels of firmness.
