Lightweight, versatile, and durable, foam materials are ideal for gaskets and seals in many of the industries we serve.
Sealpilot can manufacture and die-cut a wide range of foam and rubber materials. Foam is very efficient to use because we can maintain tolerances as low as 0.015 inches on harder materials.
We provide open cell and closed cell foam materials, and our customers have used foam rubber gaskets and gaskets in many industries, including home appliances, automotive, electronics, lighting, marine, power equipment, etc.
The range of materials we offer includes:
■ Neoprene
■EPDM, SBR and neoprene blends
■Polyurethane
■PVC/NBR
■Silicon
■Volara（XLPE）
■Microcellular polyurethane foam (PORON)
Foam materials can fill large voids and gaps, and also have cushioning properties to help reduce impact between the two substrates. Closed-cell foams are ideal for sealing and help reduce the flow of liquids and gases, while open-cell foams offer more flexibility and can be manufactured at high or low densities.
Depending on the intended application, foams can also be treated to have resistive properties. It can be laminated and applied with adhesives to withstand strong pressure situations. Foam has natural fire and flammability properties and can be sealed to withstand many chemicals and acids. In addition, the foam material is ideal for outdoor applications because it is resistant to weathering, UV rays, and fungus.
Please review the table below for a complete list of open and closed cell foam materials.

So which material is right for your application?
Closed-cell foams have thin pore walls, so they are very lightweight, but the material is usually hard due to the incompressibility of the gases in them. In terms of resistance to liquid permeability, closed-cell materials are superior to open-cell materials. In addition to its strong resistance to compression set, open-cell foam is softer, more breathable and easier to compress. In other words, it is a measure of its hardness or load-bearing capacity.
If you just want light weight and good cleaning performance, then use closed-cell foams. If you want comfort, softness, breathability and long-term reliability, choose open-cell foams. If your product is not satisfied with this, we have a professional team to help you choose the right material for your product.
We stock a wide variety of materials to help shorten the delivery time. In addition, duplicate products contain stored setup information, and turnaround times are typically as low as 24 hours.
