CPE、CM为白色粉状弹性材料，其软化点在-25℃以下，因此容易粘结成团。为防止在贮运过程中CPE颗粒的粘结，产品出厂时已掺加防粘剂，但贮存时仍应注意，不宜层层堆放，而要采用架松，避免产品在长期堆压过程中粘结成块，夏天高温更应注意。CPE、CM颗粒粘结后，并不影响产品本身性能，对橡胶行业并不影响加工。

CPE、CM is a kind of white powder elastic material, its softening point in -25 centigrade, so it is easy to bind. In order to prevent the CPE granules binding together during storage, anti-binding agents has been added before ex-work, but still should pay attentions during storage, should not put them layers upon layers, and adopts frame support to avoid products binding together in the long period of pressure, especially in the hot summer. The binding of CPE、CM granules does not affect its product performance and also does not affect the processing in the rubber industry.
