4819 is a 100% polyester, binder and foam free, non-woven fabric. It exhibits outstanding elongation, drapability and high stretch properties. Its high stretch and absorptive qualities reduce bridging on complex contour surfaces. 4819 properties are recommended where multiple layers are needed to achieve the proper resin-to-fiber ratio. 4819 is not a release fabric. It should be used with a suitable Precision Fabrics peel ply release fabric.
4819 has a melting point of approximately 480°F (249°C)
