Closed Cell Foam

Polyethylene Foam

Foam Types: Polyethylene Foam
Standard Sizes: Full, Half
Heights: 1/4", 1/2", 3/4", 1", 1-1/2" and 2"




Features

As closed cell foam sheets or any other form it comes in, polyethylene is a very strong and resilient material which, as one of many types of closed cell foam, is ideally suited for use in many different regards. Some of the most common uses of polyethylene sheets include shock-absorbing, vibration-dampening, insulating, barriers and polyethylene foam roll styles used as buoyancy components. Polyethylene closed cell foam is an excellent material for cushioning products in packaging applications, especially in the form of polyethylene foam sheets . The excellent buoyancy as well as durability of Polyethylene foam allows it to be used in flotation equipment,and other nautical products. Additionally, polyethylene tubes can be used for a number of other purposes, including irrigation tubing and resisting acids and alkalines.
