GLASS FIBRE SUBSTRATES COMPRISING FOAM RUBBER COATINGS

摘要

Composite materials having glass fiber substrates and attached foam backings are useful in surface covering applications especially as resilient floor coverings. The glass fiber substrates are usually coated with a plastisol of polyvinyl chloride. Conventional foam rubber backings made from high solids SBR latex have poor adhesion to such coated substrates. However this problem may be overcome by using foam rubber backings made from a blend of SBR and NBR latices, which backings have excellent adhesion to these coated substrates.
