RTM Polypropylene Mat: the Go-between Layer for Optimal Resin Flow

Dymriton: The best suitable resin flow medium.

“Polypropylene mat: flow layer of Flow Mat products offers the rapid resin flow speed in close mold and infusion vacuum.”

Polypropylene Mats are non-woven mats by needle-punched polypropylene fiber which is very draped able & without a chemical binder.

PP Mat has a good impregnate property, allowing the resin to flow rapidly through the mold.

Main Application

Polypropylene Mat used in close mold process: RTM, Light RTM, and infusion Vacuum.

PP Mat was been put as the center layer and covers chopped fibers in up and bottom layer, then stitched with yarn together. It is RTM Flow Mat.

PP Mat has also been put on both sides with chopped yarn and/or reinforced mat: Biaxial, Triaxial, quad axial, WR. It is a combination mat for infusion vacuum.

Advantages

Good resin flow speed Without chemical binder Reduce process time

Specification

Polypropylene 180 Tolerance: +_10% Performance: Non-woven Handing Type: Needle Punched Thickness: 4.5-5.5 mm Width: 2600mm

Polypropylene 250 Tolerance: +_10% Performance: Non-woven Handing Type: Needle Punched Thickness: 5.6-6 mm Width: 2600mm

Surface Treatment

Polypropylene Mat acts as a go-between layer, supports the resin flow through the glass and the whole mold, saves work time, improves production efficiency.

Polypropylene Mat with a high degree of deformability, very easy to be adapt to mold cavities, suit for complex shape mold.

Polypropylene Mat doesn’t have a chemical binder which helps us to get a good and solid product. Generally, the specification is 180 g/m2, 250 g/m2, another spec also available base to your custom-made.
