Butyl pond liner

 

Why choose Butyl to line your pond?

POND LINER SIZE CALCULATOR

Butyl pond liner is suitable for aquatic projects of any size, shape or complexity. This rubber pond liner has been the choice of experts and gardeners for years, being more easily installed in all situations.

Butyl pond liner is UV resistant and has at least a 20 year lifespan. Butyl pond liner is still the best material for lining a garden pond. It should not be confused with other rubber pond liners such as Firestone Rubber which is a cheaper, inferior pond liner.

The polymer butyl (IIR - isobutylene isoprene - rubber) is an elastomer with a small number of double bonds, produced through co-polymerisation of isobutylene and isoprene.

In addition to the base polymer, Butyl pond liner contains reinforcing carbon black, fillers, process chemicals, antioxidants and vulcanising agents. After mixing the ingredients into a homogenous plastic compound, two layers of the rubber are rolled out to form a double sheet. Vulcanisation is then carried out. The long rubber molecules in the material are cross-linked through heat and pressure, creating an elastic membrane.

Butyl pond liner is resistant to the environment. The vulcanisation process means that the material differs from all thermoplastic products, in that its properties are not affected by varying temperatures. Butyl is chemically stable and always returns to its original dimensions after stretching.

The cross-linked molecular structure gives Butyl rubber liner its unique properties. Ageing or changes in characteristics are negligible despite decades of exposure to sunlight, UV radiation, water or major temperature fluctuations.

Butyl pond liner contains no plasticisers or additives which can evaporate or be washed out over the years. The strength and elasticity of the butyl pond liner membrane remain practically unchanged for decades, without shrinkage, brittleness, melting or cracking. The membrane is equally elastic, regardless of whether the temperature is -30°C or +120°C.
