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 Y shaped 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
