"Juhua®" FJP-830 FEP is mainly used in the extrusion of insulation layers and jackets for conducting wires, FEP pipes and films etc., and can meet the demands of most users. Compared with other "Juhua®"6 series FEP, it has lower impurity/non-melt matter content, better stability and excellent processability. This product contains no PFOA and PFOS, and has been approved by UL (QMFZ2: E320038, QMTM2: E312670) and SGS.
Application
It is mainly used for the insulation and jackets of wires & cables in high temp., also used for large-sized data, communication wires' jackets and high-temp./corrosion-resistant pipes, films etc.. It is not suitable for jackets and pipes with high requirements for stress resistance; or insulation of data/communication wires

Notes
FEP resin will become more corrosive when decomposed, therefore, we should avoid operation at high temperature.
When heated, FEP can generate small amount of organic fluoro-containing waste gas. During the disassembly and assembly of die, the lubricating oil in heated status will also release unpleasant gases. These gases will be harmful to human body when inhaled! They should be discharged outdoor through exhaust system.
Packing
It is semi-transparent granular solid. In PE bag which will be put in hard fiber drum; or in double-layer reinforced plastic bag; net wt. 25kgs/drum(bag).
Storage
Should be stored in clean, cool and dry place; avoid rain, sunlight, moisture and dust.
