What is Alkatuff?
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) comonomer, giving superior impact strength, stress crack resistance and long-term toughness than tanks made with a standard butene (C4) resin.
Alkatuff has more than twice the UV protection specified in the Australian Standard for polyethylene tanks. The Australian Standard for water tanks requires that the material has a UV8 rating while Alkatuff has a rating greater than UV20.
Alkatuff has high thermal stability making it less prone to oxidation, discolouration and loss of toughness making it ideal for use in rotational molded tanks produced for the demands the harsh Australian environment. Make sure your next tank is made from Alkatuff so you can be sure it’s Tough in the Sun.
Why choose Alkatuff?
- UV performance level of UV20 which is more than twice the Australian standard requirement of UV8.
- Twice the Environmental Stress Crack Resistance (ESCR) requirement of AS4766.
- Made using a C6 comonomer, rather than the standard C4, for extra strength and resistance against stress cracks.
- High thermal stability making it less prone to oxidation, discolouration and loss of toughness.
- Proven track record through supply to Australian tank manufacturers for over 20 years.
- Purpose made to perform in Australian conditions which is why we say Alkatuff is Tough in the Sun.
- Alkatuff supports tank manufacturers with local technical service and data to optimise the tank performance and design.
