PP Core Mat
CORE MAT FOR RTM
It is a stratified reinforcing glass fiber mat composed by3, 2 or 1 layer of fiber glass and 1or 2 layers of polypropylene fibers. This reinforcing material has been specially designed for the RTM, RTM light, Infusion and cold press molding
CONSTRUCTION
The exterior layers of fiber glass have an areal weight from 250 to 600 gr/m2.
To provide a good surface aspect is recommended to have 250g/m2 as minimum in the external layers,asthough other values are possible with glass fibers are 50mm long.
The standard material are the ones in the following list, but other designs are also available according to customer needs.

PRESENTATION
Width: 250mm to 2600mm or sub multiple cuts
Roll Length:50 to 60 meters according to the areal weight
Pallets: from 200kg to 500kg according to the areal weight
ADVANTAGES
Highly deformability in order to be adaptable to the mold cavities, Provides a very good resin flow due to the pp synthetic fibers layer, Accepts variation of mold cavity thickness, High glass content and good compatibility with different type of resins, Increased strength and thickness of finished products by sandwich structure design, Chopped strand mat layers without chemical binders, Reduce the lay up frequency of mat, increase the efficiency, High glass content,even thickness, Special design to catch customer requirement.
