GLASS POLYPRO PP OFFERS EXCEPTIONAL IMPACT
STRENGTH
When the matrix ductility of PPis combined with the tensile strength of continuous glass fibers, excellent impact strength is achieved. Only after high deformation do the first cracks start to appear. The energy is absorbed
during a 50 % longer time.
GLASS POLYPRO PP : EXCEPTIONAL RESISTANCE
TO WATER
The high chemical inertness of PP provides
GLASS POLYPRO with exceptional resistance to the
presence of the water.
Ageing in boiling water shows only a 10 % loss in
tensile and shear strengths.
No sign of ageing, either surface aspect or
mechanical properties, was seen after 1200 hrs of
immersion in 65°C water.
After continuation to 4800 hrs, the loss in properties
did not exceed 10 %.
