Chemical Tank

POLYCHEM are one piece seamless tanks produced from polyrethylene using rotationl moulding process which offer superior quality as they are corrosion resistant, flexible and will not break or shatter under normal expansion and contaction. POLYCHEM tanks are competitively priced and suitable as storage tanks for a wide range of chemicals and can be used by water and wastewater industries and any industry that require storage of chemicals

POLYETHLENE RESIN

Polytehylene resins used to manufacture POLYCHEM is an ethylene octane copolymer specifically designed for applications requiring excellent environmental stress crack resistance and impact strength combined with low warpage. it is fully heat and UV stabilized resulting in good colour retention and long life expectancy. The resins complies with U.S.FDA21 CFR 177.1520@ 3.1a
