POLYCHEM tanks are premium-quality polyethylene products, manufactured using advanced rotational moulding technology to meet a wide range of water storage applications. Available in sizes from 180 to 45,000 litres, POLYCHEM tanks are offered in both standard and customised options, with WEIDA providing full technical support for tank system planning, design, and construction.
The polyethylene resin used is an ethylene-octane copolymer, designed for excellent stress crack resistance, impact strength, and minimal warpage. Fully heat and UV stabilised, it ensures long-lasting colour retention and durability, meeting U.S. FDA 21 CFR 177.1520(c) 3.1a.

Designed to International Standards – POLYCHEM tanks comply with ASTM D 1998-06, with wall thickness tailored to suit the specific gravity of the stored liquid.
Highest Quality Polyethylene – The resin used in POLYCHEM tanks is a hexene or ethylene-octane copolymer, engineered for superior environmental stress crack resistance, impact strength, and low warpage.
Strong, Durable, & Lightweight – The moulded polyethylene construction ensures tanks are easy to install, handle, and transport.
Leakproof – POLYCHEM tanks are made with seamless, single-piece construction for complete leak resistance.
Chemical Resistant – Polyethylene is inert and resistant to most strong acids and alkalis.
Corrosion Resistant – Requires no maintenance for rust prevention as polyethylene does not corrode.
UV Resistant – The material is UV-stabilised with a UV8 rating, meeting MS1225 standards.
Colour Options & Multilayer Construction – Standard colours are black and natural, with options for custom colours or multilayer construction.
Customisation – POLYCHEM tanks can be customised with various covers, fittings, and “tank-in-tank” systems, including fixtures for chemical dosing equipment.
Quality Assurance Programme – POLYCHEM tanks undergo more stringent testing compared to standard water tanks before delivery.
