Preparation of polypropylene and skim natural rubber/thermoplastic natural rubber blends: Determining processing conditions
Centrifuged latex production in Sri Lanka contributes over 25% of the country’s annual total rubber production. This share is an increasing trend, when the production figures for the last decade are considered. During the centrifugation process, concentrated or creamed latex with dry rubber content of 60% is separated as centrifuged latex, and 5% to 10% of rubber available in the field latex is removed as the diluted fraction. It has 3% to 5% dry rubber content and a high amount of non-rubbers. This diluted fraction is known as skim latex, and the rubber extracted from acid coagulation of skim latex is referred to as skim natural rubber (SNR).

Mechanism of oxidation in natural rubber compounds at lower (ambient) temperatures
The oxidation mechanism of natural rubber was studied using several techniques. In a prior article, it was found that the crosslink distribution (sulfur types including polysulfidic, disulfidic and monosulfidic) in a belt coat (conventional cured natural rubber compound) had a different crosslink distribution, depending on the aging temperature (ref. 1). The belt coat compound extracted from an oven aged (65°C) tire was compared to the belt coat compound extracted from a normal service tire (23°C, the average annual temperature in Phoenix, AZ)
