Double Centrifuged Latex
Double Centrifuged Latex is highly purified Latex concentrate prepared by re centrifuging centrifuged latex that has been suitably diluted. As a result the water extractable proteins and non – rubber constituents are further reduced. Films prepared from DC latex exhibit greater clarity, low water absorption and high dielectric properties. DC Latex finds applications in surgical dipped goods and other specialized premium latex products where these properties are important. The Latex is generally very stable and has good storage properties.
