Chemically resistant foam has the ability to resist damage or corrosion when it comes in contact with a variety of chemicals or solvents.
PolyCell™ EVA and Polyolefin (POE) foams have very high chemical resistance compared to other soft foams. This is due both to the inherent nature of saturated linear polyethylene as well as the introduction of crosslinking in the later stage of the molding process.
In addition, the closed cell and non-absorbent nature of its skin also allows a chemically resistant foam to safeguard against common cleaning chemical agents used in household, commercial or hospital products.
|In such applications chemical resistance is better than polyurethane foams. In general, EVA and POE foams are resistant to most of the polar fluids such as acids, alkalis, amines, and glycols.
The saturated nature of the backbone polymer and cross linked structure also provides resistance against hydrocarbon and common solvents in a way that can not be matched by unsaturated materials.
PolyCell™ is the perfect solution for products in water environments that are exposed to chemicals such as chlorine and cleaning solutions.
EVA and POE foams also exhibit a wide range of corrosion resistance.The resistance ranges from potable water to corrosive waste. They are also resistant to most of the mineral acids including sulfuric acid, up to fairly high concentration as well as inorganic salts including chlorides, amines, alkalis and many organic solvents.
