PE water tanks are robust enough to cope with rough treatment from livestock and bumps from farm equipment, and farmers understand that even the delivery process can be rough down a country dirt road.

Relatively light-weight PE tanks made from Qenos material have been successfully delivered and installed far and wide. Combined with the harsh Australian weather – UV, heat and wind - the tough conditions make the 30 year trouble-free performance delivered by PE water tanks even more admirable.

Qenos has specialised understanding of the requirements of tank material and it needs to be tough, durable and UV resistant. Qenos Alkatuff LLDPE is specifically designed for use in water tanks. The long service life is planned and tested for when the polymer is produced. High resistance to impact and abrasion, high tolerance to environmental stress cracking and long term resistance to UV degradation are features of the Qenos Alkatuff PE grades used in plastic tanks by Australian manufacturers.

As a local supplier, Qenos has long history and strong relationships with the Australian plastics industry and in particular the water tank and roto-moulding industry. Qenos is ideally positioned to meet Australian needs with specialised laboratory, production and testing facilities and experienced personnel in Australia. Qenos has developed Alkatuff LLDPE products in Australia specifically for roto-moulding and for Australian conditions.

The Alkatuff LL711UV grade combines the fundamental toughness of linear low density polyethylene (LLDPE) with specific UV and thermal stabilisation properties. This has created “purpose built” polymers which are easy to use in plastic tank manufacture, provide excellent physical properties and deliver exceptional long term performance. In the field and the home garden, water tanks made from Qenos Australian plastic maintain their strength and integrity in Australia’s harsh climatic conditions.

The base Qenos resin Alkatuff LL711UV conforms to all of the polyethylene requirements as set out in AS/NZS 4766 – Polyethylene storage tanks for water and chemicals – in fact it far exceeds these requirements. Qenos also puts the Alkatuff PE through rigorous testing for performance – tensile, puncture, impact and UV weathering performance, and because PE tanks made with Alkatuff can be suitable for use with drinking water the Alkatuff LL711UV, LL705UV and LL755 grades all have demonstrated compliance to AS/NZS 4020 – testing of products for use in contact with drinking water.

Australian made Qenos Alkatuff polyethylene provides the maximum lifespan for plastic tanks. Designed for Australia’s tough conditions and proven in over 30 years in service, we know why Australians trust PE water tanks.
