This effect substance is great for existence casting and especially Light for casting infants and youngsters.
Stabilised to the selected consistent viscosity. Softer than other grades and utilised for top-high-quality goods.
Very low Ammonia Latex Concentrate (LATZ) – This is certainly centrifuged natural latex concentrate that's preserved with minimal ammonia with other preservatives. The ammonia written content of LATZ is just latexfashion not exceeding 0.29%. LATZ can exchange HA Latex in all usual latex apps, with just a little adjustment in compounding in specific situations. LATZ is preserved with 0.two% ammonia together with a suitable mixture of zinc oxide (ZnO) and tetramethylthiuram disulphide (TMTD) of not in excess of 0.05% in complete, according to latex excess weight. It is much more frequently used Anytime lower levels of ammonia material are most popular for instance in enclosed Areas.
