Alkatuff polyethylene is supported by local technical service and extensive technical data ensuring the design of your tank can be optimised. Qenos is an active member of the Association of [...]

Alkatuff has been supplied to Australian tank manufacturers for over 20 years and has proven performance in Australian conditions. In fact the Australian tank market was slow moving until Qenos [...]

Alkatuff resin has a broad processing window creating two important benefits: It melts and adheres to the mould readily. This is known as sintering.  It then easily releases from the mould [...]

Creep is the term used for the deformation of a material under stress. Creep can significantly affect the performance of a moulding over time.  In water tanks creep mostly manifests as [...]

The most important function of a tank is containment!  That’s why it’s very important for a tank to be resistant to cracking.  AS/NZS 4766 requires that the tank material survives 500 [...]

C6 is shorthand for the hexene co-monomer used in the Linear Low Density Polyethylene (LLDPE) from which the water tank is made (ethylene is the main monomer gas). In LLDPE, the branching in the [...]

When polyethylene is exposed outdoors, the ultra-violet component of the sunlight causes photo-oxidation of the polymer, resulting in surface crazing and a marked deterioration of the mechanical [...]

Poly water tanks are usually made by a process known as rotational moulding.  The process involves melting the polymer inside a mould which is slowly rotating inside a hot air oven.  [...]

C6 is shorthand for the hexene co-monomer used in the Linear Low Density Polyethylene (LLDPE) plastic from which the water tank is made. In LLDPE, the branching in the molecule is achieved [...]

Since the early 1990’s, linear low density polyethylene (LLDPE) has come to the fore in rotational  moulding applications, because of its outstanding  physical properties [...]

Alkatuff is an Australian made polyethylene that is specifically engineered for the production of plastic rainwater tanks for Australian conditions. Alkatuff is made with a hexene (C6) [...]

Qenos is Australia’s sole manufacturer and leading supplier of world class polyethylene and polymers.  In 2008, Qenos became a subsidiary of China National Bluestar (Group) Co. Ltd, a [...]

When polyethylene is exposed outdoors, the ultra-violet component of the sunlight causes photo-oxidation of the polymer, resulting in surface crazing and a marked deterioration of the mechanical [...]

Alkatuff is a Linear Low Density Polyethylene resin specially made for the manufacture of poly water tanks. Alkatuff is manufactured by Qenos, Australia’s sole manufacturer and leading supplier [...]

If your tank is not made from Alkatuff, then it’s not Australian made and is likely made from a resin manufactured in Asia or the Middle East and not specifically designed for Australian [...]

Poly water tanks are a cost efficient way to store rainwater for domestic, industrial or commercial applications. Plastic rainwater tanks will not only save money in the long run due to lower [...]
