ZDEC based vulcanizing package for latex sheeting

ZDEC based vulcanizing package for latex sheeting


I need to create a rubber sheeting from HA latex. It must have a high resilience, tearing resistance, flex fatique life and rebound elasticity. Thus, I chose a conventional postvulcanization with sulfur, ZDEC, zinc oxide and stearic acid

However, I have some problems finding the right combination of the beforementioned ingredients. Does anyone have basic formularies of what's typically used for latex products such as surgical tubing, condoms etc?

RE: ZDEC based vulcanizing package for latex sheeting

THF - here is an old condom formulation I have in my records, which should go some way to helping you. It is based on HA latex and uses emulsions and dispersions for the other ingredients.

60% LA NR latex 167.0 parts
10% potassium hydroxide 2.0 parts
20% potassium laurate 0.5 parts
50% sulfur 1.8 parts
50% ZDBC 1.0 part
50% ZMBT 2.5 parts
50% non-toxic, non-staining antioxidant 1.0 part
(phenolic type)
Water 24.0 parts

Thanks, GrahamBennett. I must do with ZDEC only for the moment, but will gladly try your formulation if my further experiments fail.
