About Foam

Made of FDA-listed materials, these polyethylene foam sheets are often used as packaging for food products to absorb shock and damp vibration. Polyethylene foam offers better resistance to chemicals than polyurethane foam and is also superior when insulating packaged objects from external temperatures. Foam has closed-cell construction, which restricts water, air, and gases from being absorbed. These sheets have an ultra-smooth texture for a sleek surface that's easy to wipe down.

Adhesive-back sheets are made of polyethylene that is FDA compliant; however, their adhesive does not meet these specifications.

Food Industry High-Temperature Silicone Foam Sheets and Strips

Seal and damp vibration around high-temperature food-service equipment with these silicone foam sheets and strips. The foam, but not the adhesive, is made of FDA-listed materials for use with food. Silicone maintains its flexibility across a wide range of temperatures. These sheets and strips have an ultra-smooth texture for a sleek surface that's easy to wipe down.

Open-cell foam allows water, air, and gases to be absorbed.

Closed-cell foam restricts water, air, and gases from being absorbed.

Gasket Tape for Pipe Flanges

Because this expanded PTFE tape is thicker than other gasket tape, it fills the irregularities on rough-surfaced flanges when compressed for a tight seal. This gasket tape is chemically inert, except to molten alkali metal and elemental fluorine.

Gasket tape that is FDA Compliant 21 CFR 177.1550 is for use with food and beverage.

Gasket Tape

Very soft and conformable, this expanded PTFE gasket tape compresses into an extremely thin profile. Use it to create a leak-resistant seal in tight-tolerance applications, such as on precision machinery. This tape is chemically inert, except to molten alkali metal and elemental fluorine.

Gasket tape that is made with FDA-listed material is for use with food and beverage.

Foaming Agents for Plastic Molding Machines

Commonly used in molding applications such as injection molding and extrusion, these foaming agents reduce weight, warpage, and sinks in finished parts. Mix them into resin as 0.5-1.5% of the total mixture—by decreasing the amount of resin needed to make a part, they help reduce costs. They also lower the melt viscosity of resin so that it can be processed at low temperatures, which reduces cooling times, cycle times, and the risk of heat degradation. These foaming agents are compatible with most plastic and rubber resins. All are FDA compliant for direct contact with food.

Agents with a 310° F or 325° F activation temperature are for use with low-melt-temperature resins such as polyolefins, polystyrenes, and thermoplastic elastomers. Agents with a 400° F activation temperature are for use with high-melt-temperature resins such as polycarbonates and polyamides.

Microfine agents produce smaller bubbles and a tighter cell structure than other foaming agents. They improve the appearance of your final product and keep its mechanical properties consistent throughout. They’re often used to create parts that have thin walls.

Fine agents produce more gas than microfine agents. Use them to ensure uniform foaming when molding bigger parts.
