Binder Chemistry Selection for Nonwoven Performance
topic
Nonwoven binder chemistry selection from acrylic, styrene-butadiene, ethylene-vinyl acetate, and polyvinyl acetate latex systems is governed by application performance requirements including dry and wet tensile strength, flexibility at service temperature, chemical resistance, FDA compliance for food contact or skin contact applications, and VOC emission limits for indoor air quality compliance in consumer product applications.
Role
Determines the bond strength, flexibility, chemical resistance, and regulatory compliance of chemically bonded nonwovens through binder polymer chemistry selection that must simultaneously satisfy the mechanical performance requirements of the nonwoven application and the regulatory, environmental, and safety requirements that apply to the finished product in its end-use environment and geographic market.
