Silicone only has a surface energy of 24 dynes/cm, so the molecular force between epoxy and silicone is weak. This makes silicone an ideal material for creating a packer for cured in place pipe repairs, because the resin will slide off of the silicone surface as opposed to a rubber bladder which will react negatively when in contact with epoxy.
Since silicone bladders are more efficient, they can also be thinner. This bladder tube is only 1mm thick.
These bladders can be used for hot water curing or steam curing. They withstand a temperature to a maximum of 80 degrees Celsius (176 degrees Fahrenheit).
They have a seamless weld which makes them strong, so the chances of them leaking is reduced significantly.
Recommended pressure: 0,7bar to a maximum of 1,0 bar. (Except the 200mm upward. The recommended pressure for these is 0,5 bar to a maximum of 0,7bar.)
Bladders are 10% below nominal diameter. So for example DN100 is 90 mm DN150 is 135mm etc. When pressurized they expand to the pipe diameter
