Main Application

• JF-4DE10:It is mainly used to make substitute PFA for the processing of thermoelectric heat exchanger tubes, and has good welding performance;
• JF-4DE11:It is mainly used to make the push processing of oil pipelines.

Packing, Storage & Transportation

• 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.
