<p><strong>PVC Pond Liner History</strong></p>
<p>The full name of this product is Polyvinyl chloride and it was discovered by <a title="Henri Victor Regnault" href="http://en.wikipedia.org/wiki/Henri_Victor_Regnault">Henri Victor Regnault</a> in 1835. In early 20th century the Russian chemist <a title="Ivan Ostromislensky" href="http://en.wikipedia.org/wiki/Ivan_Ostromislensky">Ivan Ostromislensky</a> and <a title="Fritz Klatte" href="http://en.wikipedia.org/wiki/Fritz_Klatte">Fritz Klatte</a> of the German chemical company Griesheim-Elektron attempted to use PVC in commercial products, but difficulties in processing the rigid, sometimes brittle polymer blocked their efforts. But it was subsequently found that the addition of plasticisers helped to soften the product making it easier and more desireable to work with. PVC wasn’t actually patented until 1913. Over the years pond liners is just one of many thousands of uses for this product. By the 1950s PVC was the preffered material for hose and piping as it offered many benefits over previously used metal.</p>
<p> <strong>PVC Pond Liner Qualities</strong></p>
<p>As PVC has striking similarities to rubber it is an obvious choice to be used as a pond liner. This product offers a degree of elasticity. It is a denser, heavier product than polyethylene and more expensive to produce. It is not tear-proof like Flexiliner. The material is great at combating root penetration though it is not so good at extreme temperature – it can become brittle and snap when very very cold and yet become very thin and feeble if the temperature gets very hot. That said, these situations affect the product more pre-installation as once in the ground it is stable.</p>

<p><strong>PVC Pond Liner Installion Tip</strong></p>
