Polypropylene mat is made up of polypropylene fiber needles punched together. Polypropylene mat used in unsaturated polyester, epoxy resin system.
Applications require higher bending stiffness and strength without adding weight.
- Used in unsaturated polyester, epoxy resin system.
- Applies in hatches, small boat hulls, pressure vessels.
- Afford resin fast flow through infusion vacuum, RTM, LRTM process.
- B=120 g/m2
- C=180 g/m2
- D=250 g/m2
- Rapid wet-through.
- Without chemical binders.
- Good covering and degassing properties.
- Compatibility with a different type of resins.
- Conformable to complex, double-curved shapes.
- Provides a wide thickness range to avoid tight or loose areas.
- Provides a very good resin flow, saving the whole process time.
- The high degree of deformability to be adapted to different mold cavities.
- With equality performance, no stain, print.
- No hole, agglomeration, stain in whole rolls.
