How can foam rubber be compressed

Compression Set Compression set or C-set resistance describes the ability of a rubber material to return to its original thickness after a compressive load, such as from pushing or pressing, is released. Solve Your Sealing Challenges Sealing challenges are complex and no two applications are the same.

Flexible polyurethane foams are used for vibration control and shock absorption. They provide increased energy absorption with increased density, predictable performance under compressive force, and low permanent deformation under constant resistance.

Applications include hood gaskets in mobile equipment, shock absorbers for industrial machinery, and vibration isolators for appliances. Polystyrene foams are rigid, structural materials that are strong, lightweight and moisture resistant. They help reduce product weight and have a high stiffness-to-weight ratio. Other types of structural foams have a sandwich-like structure with a foam core between two thin but solid layers.

Reticulated foams are used for filters and be compounded with bactericides, fungicides and other additives. Foam rubber that is fabricated into elastomeric pads can be attached to vacuum tooling for manufacturing.

During foam rubber fabrication, sheet materials or extrusions are converted into finished products. Water jet cutting makes fine, fast cuts and eliminates the mis-cuts and material waste associated with manual cutting operations. Custom-fabricated foam rubber products also support the use of tapes that use either a heat-activated taping system HATS or a pressure-sensitive adhesive PSA.

A variety of bonding methods are available for custom gaskets, but not all of them are suitable for foam rubber. Like foam rubber, sponge rubber has a cellular structure and is available in different densities. Typically, they are listed as soft, medium, and firm. There are two main types of sponge rubber.

Open-cell materials contain open, interconnected pockets that permit the passage of air, water, and other chemicals when the material is not compressed.

Closed-cell sponge rubber contains balloon-like cells that hold nitrogen gas and thus prevent the passage of these substances at low pressures. To produce open-cell sponge rubber, sodium bicarbonate is added to other ingredients in a heated mold.

As the uncured sponge rises like a cake, the baking soda creates open, interconnected cells. To make closed-cell sponge rubber, a chemical powder that decomposes under heat and pressure is added. Foaming is specific production process, and foam rubber contains mostly open cells. Log in. Study now. See Answer. Best Answer. Study guides. Genetics 20 cards. What are chromosomes made of.
