3. Attention for storage and transportation
PVDF products are packaged in polythene bags. Products should be stored in a clean, dry warehouse to prevent impurities from being introduced. This product is non-toxic and harmless at normal temperature, but it is necessary to pay attention to the processing temperature to avoid exceeding 300ºC to prevent decomposition of toxic gases.
