High Load Bearing (HLB)
Sheets of polyurethane foam are just one of the many products supplied by Advanced Seals & Gaskets Ltd, available in a wide range of grades, including our High Load Bearing (HLB) foam sheets.
Polyurethane foams are commonly used in everyday applications, including furniture, automotive interiors, and seating solutions. HLB foams are produced in master buns or blocks measuring approximately 2.3m × 2m or 2.3m × 1m, which are then split into sheets using our state-of-the-art industrial splitters. These machines function like giant precision peelers, programmed to remove layers of foam to create sheets in the desired thickness, starting from around 1.5mm.
These sheets can be supplied as full sheets or further converted into washers, gaskets, strips, and custom components using our range of presses, saws, and routing machines.
Why Use High-Load Bearing Foam Sheets?
HLB foam sheets are highly valued for their load-bearing properties, impact resistance, and ability to withstand heavy forces. Like other polyurethane foams, HLB sheets can be produced in different densities and grades, including flame-retardant (FR) options.
High-density polyurethane foams are also known for their viscoelastic properties, which enable them to resist compression and recover effectively after pressure is applied. HLB foams can be combined with lower-density materials to create hybrid sheets that offer bespoke firmness levels, tailored for specific applications.
Common uses of HLB foams include mattresses, boat seats, campaign mats, pet bedding, sports mats, and protective packaging.

HLB foam sheets excel at distributing weight evenly, making them suitable for applications where support and stability are critical.
The high-density structure provides excellent structural integrity, preventing deflection or deformation under heavy loads. This makes HLB foam ideal for construction, manufacturing, and industrial applications.
The dense composition of HLB foams allows them to absorb shocks and impacts, protecting delicate items or providing cushioning in seating and automotive interiors.
Thanks to their robust and high-density nature, HLB foam sheets are long-lasting and withstand heavy-duty use without significant wear or loss of performance.
These foams maintain their shape under pressure, offering consistent support and structural reliability in both industrial and commercial applications.
The dense foam structure also provides effective vibration damping, which is useful in machinery, transportation, and the protection of sensitive equipment.

What are High Load-Bearing Foam Sheets?
HLB foams are manufactured from master blocks measuring approximately 2.3m × 2m or 2.3m × 1m. These blocks are fed through precision splitters that peel off layers to create sheets of the desired thickness, which are then rolled by hand.
Like all polyurethane foams, HLB sheets are made from polyol (a petroleum-based material) and diisocyanate, which combine to form the dense, supportive foam.
HLB foam sheets are widely used across various industries due to their support and shock absorption properties. They are particularly popular in furniture and automotive interiors, as well as protective packaging for fragile electronics, providing cushioning and preventing damage during transport.
HLB sheets can also be produced in varying firmness levels, independent of density, to meet specific application requirements.
Benefits of using High-Load-Bearing Polyurethane Foam
- Durable and sturdy
- Excellent viscoelastic recovery
- Available in a range of sheet sizes
- Can be laminated to other materials
- Flame-retardant (FR) and anti-static grades available
- Easy to cut and shape
Advantages of using High-Load-Bearing Polyurethane Foam Sheets
HLB foam sheets are crafted from master buns, enabling bespoke sheet sizes, thicknesses, and finishes. They are used in a variety of industries, including:
- Commercial and residential seating: Often replacing springs, providing stability and comfort.
- Automotive Interiors: Cushioning for Seats and Panels.
- Industrial applications: Buffer pads, impact protection, and seals or gaskets.
- Protective packaging: Safeguarding fragile electronics and components.
High load-bearing PU foams can also be laminated to other materials, providing bespoke firmness levels for specialised applications. Their versatility, durability, and support make them ideal for almost any project requiring high-density foam.
