Abstract (en)
[origin: WO2020264416A1] A non-woven fibrous mat is provided that includes a mixture of a thermoset resin and a thermoplastic resin. It has been found that the physical properties (e.g., flexibility, tensile strength) of a non- woven mat may be improved by formulating a binder composition comprising variable ratios of the thermoset material and the thermoplastic material. In this way, a bonded nonwoven mat may be achieved having a desirable combination of strength and flexibility, while maintaining good heat and water resistance.
