PU Gaskets

Product specification

Material and function

Polyurethane foam is used for compliant cushioning, damping and sealing. Polyether, polyester and cell-structure choices serve different environments. Open-cell and closed-cell forms should be selected for the required function.

Benefits and options

• Compliant cushioning
• Acoustic and vibration damping
• Cell structure and density selection

Manufacturing and customization

Sheets and suitable foams can be precision converted into gasket outlines. Molding is considered where the geometry needs a three-dimensional seal. Choose the cutting route and adhesive backing for the material and shape.

Design considerations

Select the material grade for contact media, operating temperature and mechanical loading. Include the installed compression, mating surfaces and expected service conditions when reviewing the component. Confirm performance using the selected compound and a representative sample.
