Needle-punched nonwovens, sometimes referred to as mechanically bonded nonwovens, are used for automobile insulation, trunk liners, headliners, as interlining and also in filters. Needle-punch nonwovens saturated or coated with emulsion polymers will provide softness or stiffness that may be required, or other properties like hydrophobicity or tensile strength.
Rovene 4402 is a styrene-butadiene emulsion polymer that has a medium soft hand with outstanding strength properties.
Rovene 4470 is a styrene-butadiene emulsion polymer that provides good aging properties, water resistance, and adhesion to a wide variety of fibers.
Rovene 4021 is a self-crosslinking, carboxylated styrene-butadiene emulsion that has a firm hand with outstanding strength properties. This latex is especially suited for various nonwoven, textile and performance coating applications.
Rovene 4201 is a self-crosslinking, carboxylated styrene-butadiene emulsion that has a stiff or ‘boardy’ hand. This binder is recommended for durable nonwovens such as floor maintenance pads and roof shingle mats, both glass and organic.
Rovene 6065 is a styrene-acrylic polymer that is a tough, durable nonwoven binder intended to provide improved stiffness and strength.
Rovene 6066 is a styrene-acrylic emulsion polymer specifically designed for formulation of binder systems for moldable and self supporting composites.
