Prolite polypropylene tubing offers general chemical resistance. Other properties include low surface friction, corrosion-resistance and high dielectric strength. The lightweight tubing offers low moisture absorption and is manufactured from a compound that is NSF Standard 61 certified for drinking water applications. Sizes range from ¼- to 1.25-in. OD.
Trial and error methods are often used when developing products. Thomas Edison, with 1,093 patents, more than any other inventor, took many products and ideas and made them better. He would merely take a very good product, such as the light bulb, and make it commercially available. The light bulb had already been invented and used in labs, but Edison took the idea and developed it into a cost-effective product that could be sold commercially.
A few savvy tweaks greatly impact product development
Fluoropolymers have a long history in our society. Polytetrafluoroethylene (PTFE) was discovered in April 1938 at DuPont’s Jackson Laboratory in New Jersey by Roy J. Plunkett. During World War II, PTFE was used in the Manhattan Project in the development of the atomic bomb. It was also used in Oakridge, Tenn., as a gasket and packing material in a gaseous diffusion piping system handling uranium hexafluoride, a very toxic and corrosive gas. Only Teflon could do the job.
The evolution of plastic tubing in the water industry
Researching and developing water treatment products and components reveal a lot of information and observations. A recent study on the efficacy of porous PTFE tubing for the transfer of gases, such as ozone or oxygen, into water proved some very interesting theories and revealed some additional data. One test done on lake water (Water Quality Products, December 2004)1 proved very beneficial in reducing bacteria. The comparison of ozone transfer against several sizes air stones and a venturi in this test was also very interesting.
What method works best and why?
Recent studies were conducted on porous PTFE tubing to test the efficacy of how well the tubing transfers ozone into water.
