Abstract:
Nowadays, the difficulty in natural rubber latex quality control in latex foaming
production process still exists. The uncontrollable void space in rubber foam causing by high
contents of soap in latex is still one of the main problems since soap content in in latex has
not been determined. Latex foam producers are not successful in making foam from every
batch of concentrated latex raw material. The rising ability of foam depends on combined
factors of some parameters for example KOH number, the content of magnesium and volatile
fatty acid, etc. To provide a more effective method for foam stability assessment,
we proposed a new simpler and faster method for Hevea brasiliensis latex foam stability
assessment for latex foam production process. Foam stability half-life before foam baking has
been proposed as a quick monitoring method. The new foam stability assessment method is
not only uses less chemicals and consumes less time but also in good agreement with
the current method (R2 = 0.595±0.005) which indicate with baked foam density. Moreover,
the correlation coefficient between KOH number and half-life time of foam stability before
baking (R2 = 0.982±0.001) was found significantly higher than that of KOH number and
density of baked latex foam (R2 = 0.547±0.430)
