Rovene® 4487

CARBOXYLATED STYRENE-BUTADIENE EMULSION

Product Description

Rovene 4487 is a styrene-butadiene emulsion polymer recommended for carpet applications that require excellent wet strength properties. Rovene 4487 can be compounded to high solids using calcium carbonate, clays and alumina rihydrate as fillers; sodium polyacrylate thickeners are commonly used to obtain the required application viscosity. Rovene 4487 imparts good wet/dry tensile strenth, and has good adhesion to a wide variety of surfaces. This adhesion contributes to the good tuft binds and excellent delaminations in carpet applications. Rovene 4487 has a large filler tolerance, strong films at high filler loads, and low water absorption.
