• JF-4D06：The molecular weight is 2-4 million, and the product has good fiber-forming properties. It is suitable for the production of short fiber products. The film is transparent in the process of processing and sintering. It has certain strength. When the fiber is stretched, there are lots of soft horizontal fluff and small shrinkage. It is also suitable for filter membrane products with low processing strength and high air permeability;
• JF-4D07：The molecular weight is 8-10 million, and the product has good fiber-forming properties. It is suitable for the production of long fiber products. The film is transparent during processing and sintering. The rolling is neat. The stretching is not easy to break. It has good strength and small shrinkage. It is also suitable for special film products with high processing strength and low air permeability.

• JF-4D06：It is mainly used as raw material for making short fiber of filter material and filter membrane, and also be used for processing medium and high density seal tape;
• JF-4D07：It is mainly used as raw material for making long fiber of filter material or filter membrane.

• Net weight：（20±0.1）kg/bucket;
• Not classified as hazardous for transportation, avoid the violent vibration, the high temperature insolation and ground bumps during transportation;
• Packed in a sealed double layer polyethylene bag which is bound with special buckle, then put into a moisture-proof rigid paper bucket;
• Should be stored in a clean, cool, dry warehouse to prevent from the moisture, dust and other impurities contamination, resin agglomeration.
