UV RESISTANCE
GRP pipes are UV resistant. If the material is used above ground and is therefore exposed to sunlight, it is guaranteed that the structural integrity and UV resistance of the pipes will not change.
OSMOSIS
Osmosis or osmotic pressure occur when the prescribed processing temperatures have not been maintained or chemical components in the laminate have not reacted with the resin. Inclusions of highly concentrated resin components and surrounding "less" concentrated water diffuse into the material through concentration compensation. This physical process creates osmotic pressure which, depending on the ambient conditions, can lead to the formation of bubbles.
In order to rule this out, a high processing and hardening temperature of 110 degrees Celsius is maintained during production. In reaction resin systems, errors in the mixing ratio of the resin components, low processing or hardening temperatures or binders can be a cause of osmosis.
Osmosis does not occur in the GRP pipes we use. The guaranteed adherence to the mixing ratios and processing temperatures as well as a perfect, constantly controlled composition of the resin is an essential aspect which the manufacturer strictly adheres to.
