Abstract: Foam particles of propylene polymers which have shrunk from 40 to 95% of their original volume and have a bulk density of from 10 to 30 g/1 can be expanded if they are treated with air or nitrogen under superatmospheric pressure, subsequently decompressed. If desired post-foamed by heating and, after aging, re-treated with air or nitrogen under superatmospheric pressure, subsequently decompressed and aged under atmospheric pressure until the pressure in the cells has dissipated.
Abstract translation: 如果在超大气压下用空气或氮气处理，则其膨胀的丙烯聚合物的泡沫颗粒已经收缩了其原始体积的40至95％并且具有10至30g / l的堆积密度，随后减压。 如果需要通过加热发泡，并且在老化之后，在空气或氮气中在超大气压下再次处理，随后在大气压下减压和老化，直到电池中的压力消散。
