 Centrifuged latex HA is natural rubber (NR) latex concentrate, centrifuged and preserved after concentration with ammonia only, with an alkalinity of at least 0.60 % (m/m) calculated with respect to the latex.
Centrifuged Latex is mainly used for producing mattress, condoms, gloves and all type of rubber products.
