Poly vinyl acetate (PVAc, poly(ethenyl ethanoate): commonly referred to as wood glue, white glue, carpenter ʼs glue, school glue, or PVA glue) is an aliphatic rubbery synthetic polymer with the formula (C4H6O2)n. It belongs to the polyvinyl esters family with the general formula -[RCOOCHCH2]-. It is a type of thermoplastics. As an emulsion in water, PVAc emulsions are used as a good adhesive for porous materials, particularly for wood, paper and cloth. The stiff homopolymer PVAc, can be used as base resin in paint and other coatings, as binder in nonwovens, glass fibers, filter paper and textile finishing.
RPX and RPN are aqueus dispersion of carboxylated styrence-butadiene copolymer. styrence-butadiene carboxylated latex are among the most worldwide used elastomers, employed in a large variety of applications which significantly contribute to our standards of living. RPX is used as a stiffener for conventional coating and desinged for non- woven fabric impregnation and coating such as automotive products, needle punch carpets. This kind of latex hasgood adhesion to most surfaces, high degree of stiffness, excellent, execellent water resistance and high durability.
