The material which the Onda manifolds are made is a techno-polymer loaded with glass fibers selected for heating and cooling systems applications.
The advantages found thanks to the use of this particular composite material are:
- Very high rigidity (modulus of elasticity in traction up to 22 GPa at 23 ° C)
- Strong resistance to mechanical stress
- High bending stress (can reach 330 MPa at 23 ° C)
- Good dimensional stability that allows compliance with minimum tolerances
- High resistance to deformation
- Very low coefficient of linear thermal expansion (comparable to that of metals or metal alloys)
- Less than 1% deformation after 1000 hours with 50 MPa at 50 ° C (value much higher than that of most techno-polymers).
- Excellent surface finish
- Resistance to chemicals, UV rays, ozone ...
- Very low water recovery (much slower than other compounds such as PA66)
- Anti-condensation (detail that makes it mandatory to use a manifold with composite material in radiant systems that provide for summer cooling)
- Absolute unassailable from any corrosion (calcareous sediments…).
