TG-MS analysis of nitrile butadiene rubber blends (NBR/PVC)

摘要

Blends of nitrile butadiene rubber (NBR) with polyvinyl chloride (PVC) are widely used in products such as hoses and seals. As part of a project that uses NBR/PVC blends for manufacturing forest fire hoses, blends of NBR/PVC with various inorganic fillers, such as Mg(OH)_2, china clay (organic modified kaolin) and nano clay (organic modified bentonite) were studied by TG-MS. No significant changes were observed to the type of the polymers' decomposition products, compared to that of NBR/PVC blend without additives. The most remarkable change was the absence of HC1 from decomposition products in the presence of the Mg(OH)_2 additive.
