PolymerLatex increasing NBR latex prices

Marl, Germany -- PolymerLatex is increasing prices for the NBR latex product range worldwide by 80 USD per tonne wet effective from 1st April 2009. According to the company, the price increase is necessary to offset the continuous rise in raw material costs for Acrylonitrile. Further price increases can not be ruled out, as Butadiene is expected to remain in tight supply world wide.

You are at the site for answers and solutions to all your problems in natural rubber latex processing and manufacturing of industrial, household and medical gloves, condoms, catheters, baby teats and baby pacifiers, toy balloons, latex foam products, latex threads etc.

Dear Ismail,

As the rubber particles of Nitrile latex are very much smaller than those of the natural rubber latex, there is a tendency of the Nitrile rubber particles to "rob" away the stabilisers from the Natural rubber particles i.e. desorption of the surfactants from NR latex to Nitrile latex. This would result in the instability of the blend.

You therefore have to pre-stabilise the NR latex well before mixing it with Nitrile latex. Also, pH of Nitrile latex should be adjusted to that of the NR latex before blending.

If you need further help, please send an email to me at woonsungliang@yahoo.com.sg

Regards

John Woon
