Polyethylene closed-cell foam plate is also called joint filler board, which is a new type of joint water-stop material . It has been repeated proved that the performance is much better than wood, cork, rubber, asphaltby China's Ministry of Communications Academy of Sciences .
1. Common closed cell foam
It is a kind of new water-stop material. It is widely used in joint plate of expansion joint for concrete road, bridge joint water-stop plate, water conservancy project, and slope projection and so on.
2. Microcell closed cell foam
The Microcell is a kind of closed cell cross linked polyethylene foam with excellent buoyancy, strength and shock absorption, flexible and is resistant to mildew mold, rot and bacteria. Also has a superior chemical resistance.
3. Neoprene closed-cell pvc foam board
Neoprene is soft and flexible closed cell polyethylene foam. It is a sponge rubber filling and is durable. Also it has good thermal & moisture insulation, this type of foam is resistant to form fitting and water, ozone, sunlight, oxidation, and chemicals.
4. Polyethylene closed cell foam
This kind of close cell polyethylene foam is of water absorption, which protects the product during both shipment and storage, and increases the foam's strength. Also it is resistant to most chemicals and oils, and it is non-staining and has high weathering and ozone resistance. This foam is also lightweight, clean, easy to use, strong and non-absorbent. This foam will easily float on water too.
Low surface bibulous rate, good performance of anti osmosis
Resistance to solvent corrosion like acid, alkali, salt, oil, etc.
Good performance of ageing resistance
Not flow in high temperature, not embrittle in low temperature
