When it comes to modern sealing and cushioning applications, flexibility, consistency and performance are non-negotiable.
A polyurethane foam gasket offers a highly versatile solution across multiple industries, combining excellent sealing capability with lightweight construction and cost efficiency.
From automotive and engineering environments to packaging, NVH insulation and electronics, polyurethane foam gaskets are trusted for their adaptability and reliable performance under compression.
At Ramsay Rubber, polyurethane foam gaskets are engineered to meet exact application demands, offering bespoke designs, specialist grades and full in-house manufacturing capabilities, all from our West Midlands facility.
A polyurethane foam gasket is manufactured from low-density, open-cell polyurethane foam.
This unique cell structure allows the material to compress easily while maintaining a consistent seal across uneven or irregular surfaces.
When compressed, the foam fills micro-gaps, helping to prevent the migration of air, dust and water.
Unlike many solid rubber alternatives, polyurethane foam gaskets are extremely lightweight, making them ideal for applications where weight reduction is a priority without compromising sealing performance.
In many sealing applications, a polyurethane foam gasket offers a more economical solution compared to traditional sponge rubber materials. Its low density and efficient material usage help reduce costs while still delivering excellent sealing, insulation and vibration-dampening performance.
This makes polyurethane foam particularly attractive for high-volume applications where cost control is essential without sacrificing quality or reliability.
Polyurethane foam is widely used because it offers a strong balance of performance, durability and cost effectiveness. Key material properties include:
Excellent sealing performance against air, dust and water migration
Extremely lightweight, reducing overall component weight
Good thermal insulation, suitable for temperature-sensitive assemblies
Effective vibration dampening, helping to reduce noise and movement
Good UV and ozone resistance, supporting long-term durability
Open-cell structure, allowing controlled compression and recovery
Depending on thickness and density, polyurethane foam can also provide effective acoustic insulation, making it suitable for NVH (Noise, Vibration and Harshness) applications.
A polyurethane foam gasket can be used across a wide range of industries and environments, particularly where controlled compression and flexibility are required.
Common applications include:
Automotive components, including sealing, NVH insulation and vibration control
Engineering and industrial assemblies, where tolerance variation must be accommodated
Electrical enclosures, protecting sensitive components from dust and moisture
Packaging and cushioning, preventing impact damage during transit
Thermal and acoustic insulation, where energy efficiency or noise reduction is critical
Because polyurethane foam gaskets conform easily to mating surfaces, they are particularly effective in applications where rigid materials may struggle to achieve a reliable seal.
Not all polyurethane foam is the same. Depending on the operating environment, specialist grades may be required to meet regulatory or performance standards.
Ramsay Rubber stocks and converts a variety of specialist polyurethane foam grades, including:
Fire-retardant grades, suitable for applications with strict fire safety requirements
High-density firm grades, offering increased durability for more rigorous use
Conductive and static dissipative grades, ideal for electronic and sensitive equipment
By selecting the correct grade, a polyurethane foam gasket can be optimised for longevity, safety and performance within its specific application.
Ramsay Rubber manufactures a wide range of polyurethane foam gasket formats, offering complete design freedom for bespoke applications. Available options include:
Plain polyurethane foam gaskets
Self-adhesive polyurethane foam gaskets
Double-sided adhesive gaskets
Kiss-cut gaskets supplied on a roll
Perforated gaskets for specialist uses
Adhesive backing options include acrylic and synthetic rubber tapes, selected to suit environmental conditions and bonding requirements. Features such as finger lifts or tabbed liners can also be added to improve handling and speed up assembly on production lines.
Choosing the right polyurethane foam gasket can significantly improve sealing performance, durability and assembly efficiency. Whether you require a simple self-adhesive gasket or a complex, multi-layered solution, expert guidance can make all the difference.
