Description

This silicone bladder is engineered specifically for Cured-In-Place Pipe (CIPP) and pipe relining work, where reliability and clean release from epoxy resins are essential. Thanks to silicone’s low surface energy (approx. 24 dynes/cm), epoxy does not bond to the surface, allowing the bladder to be reused and removed cleanly after curing.

Unlike traditional rubber bladders, this design offers improved efficiency, reduced wall thickness, and excellent flexibility. The translucent silicone material also allows for UV curing applications, giving installers better visibility and control during the process.

Each bladder is manufactured with a seamless weld construction, improving strength and significantly reducing the risk of leakage during inflation.

These bladders are suitable for hot water curing and steam curing. They withstand a temperature to a maximum of 80 degrees Celsius (176 degrees Fahrenheit).

They are also translucent, so they can be used for UV curing as well.

Please note that the bladders are manufactured upon order, which may cause a slight delay in delivery.

Please note that silicone bladders are manufactured approximately 10% smaller than their nominal diameter.

For example, DN100 refers to the pipe size, while the bladder itself measures 90mm; DN150 corresponds to a 135mm bladder, and so on. When pressurized, the bladder expands to match the pipe diameter.

Please note that silicone bladders may experience approximately 10% shrinkage during use, which is a normal characteristic of the material.

Important note: All bladders are manufactured upon order, which may cause a slight delay in delivery.
