摘要：

The dynamic flammability properties of an intumescent fire retardant polypropylene filled with ammonium polyphosphate, pentaerythritol and melamine was discussed in this study. To evaluate the flammability properties of the materials: limit oxygen index, smoke emission, tensile strength, and our exploitation 'dynamic flammability evaluation system' tests were assessed in experiments. The results showed that the intumescent fire retardant filled polypropylene has superior flammability properties and keeps its mechanical strength. It also can be seen that CO concentration and smoke emission decrease while burning. It is concluded that this intumescent system additives is an effective flame retardant on improving combustion properties for polypropylene. (C) 1998 Elsevier Science Ltd. All rights reserved.
