ABSTRACT:
There is provided thermally stabilized polypropylene melt-blown microfiber acoustical insulation web which has a resistance to thermal degradation at a temperature of 135.degree. C. for at least 10 days. The polypropylene has a thermal stabilizer uniformly distributed within the melt-blown microfiber polymer which polymer when produced is subject to thermal and/or catalytic degradation in the absence of significant levels of thermal stabilizer or antioxidant.
