FITTINGS
ApplicationsMost PVC pipes are connected using injection-moulded fittings.
Depending on the size of the pipes, the corresponding fittings can also have significant dimensions.
Stabiliser Requirements
During injection-moulding processes, high temperature and shear occur which require specially formulated stabilisers. These needs are very different compared to pipe extrusion: stabiliser properties have to be excellent and lubrication has to be adjusted to the high shear process in moulding machines.
For fittings used for drinking water pipes, national regulations apply to the stabiliser formulations.
