Closed cell sponge
Closed cell sponge is an industrial sponge material derived from neoprene that can be used for a variety of applications. Closed cell sponge is typically used for resistance against oils, grease, and other substances. This material is can withstand temperatures ranging from -70 – 200°F, UV rays, ozone, and most moistures. The usual application of this material is used for is custom rubber gaskets and seals.

Open cell sponge
Open Cell Sponge is a material derived from other products such as neoprene. This sponge material is air-filled making it softer than solid rubber. Open cell Sponge can resist oil, ozone, and can be used in cold temperatures. This material is a great option for custom gasket applications.

Polyethylene Foam
Polyethylene Foam is an industrial foam typically used for nautical applications. This material Is very strong, shock absorbent, resilient. Polyethylene Foam is a lightweight, flexible, and cost-efficient option for your custom operations.

Micro cellular
Micro-Cellular foam is a product created from Urethane. The advantages of this material are its shock absorption, superior compression set, density, flame resistance, and ability to withstand a wide range of temperatures. Micro-Cellular Foam is typically used for battery pads, work gloves, spring connectors, and other projects.
SBR sponge
SBR Sponge is a closed cell material used for seals and other custom applications. This material is resistant to weather, UV, and ozone effects. It is a very durable material that can resist most oils and greases. SBR sponge is a cost-effective material that can be used on many different custom projects.

Cross-linked polyethylene
Cross-linked Polyethylene foam is a material typically designed for chemical storage applications. This foam is smooth and thick making it great for applications that need a thicker material. Cross-linked polyethylene is strong, resilient, has excellent shock resistance and is a great thermal insulator.

Silicone Sponge
Silicone Sponge is a closed cell material. This material has low compression, can resist flames, and has excellent fluid and fuel resistance. Silicone Sponge material is used to create custom gaskets and cushioning pads. This material is high performing in water sealing and outdoor applications.

EVA sponge
EVA Sponge is a closed cell material that is used in the creation of custom gaskets. This material is strong, chemical resistant, lightweight, and has low water absorption. This material can be a great choice for an industrial or commercial gasket and sealing projects.

Packing foam
Packing Foam is just as it sounds, foam for packaging operations. This material is highly absorbent to shocks ad impact making it perfect for packing projects. Packaging foam will ensure the safety of projects being shipped.
