Europrene® Latice 5577 BCA is an aqueous anionic dispersion of a styrene-butadiene copolymer with high solid content obtained by emulsion polymerization using fatty acid soap as emulsifier. It does not contain any antioxidant.

Sustainability
Bio raw materials can be used in production processes together with traditional raw materials. In order to attribute sustainability characteristics to the final product, Versalis applies the Mass Balance approach, an acknowledged methodology that ensures that the sustainability characteristics of the alternative raw material, mixed with traditional naphtha, correspond to those of the final product. BCA products are provided with a sustainability declaration indicating the amount of Bio-Circular Attributed component. They guarantee identical performance, quality and properties, as they do not differ in chemical composition and physical-mechanical performance from standard products.

Key Features
Europrene® Latice 5577 BCA, after vulcanization, shows good mechanical properties as high resilience, good tensile strength and elongation at break. It can be blended and vulcanized in a similar manner to natural rubber latex. Foam made of Europrene® Latice 5577 BA shows a medium indentation hardness and a good resilience.

Main Applications
Europrene® Latice 5577 BCA is used for medium stiffness moulded foams (pillows, mattresses, topper) related to Dunlop, Talalay, gel/no gel processes. It can be used in gel and no-gel carpet foams.
