FEP Resin (DS618) for jacket of high speed and thin wire & cable
FEP DS618 series is a melt-processible copolymer of tetrafluoroethylene and hexafluoropropylene without additives that meets the requirements of ASTM D 2116. FEP DS618 series has good thermal stability, outstanding chemical inertness, good electrical insulation, non-aging characteristics, exceptional dielectric properties, low flammability, heat resistance, toughness and flexibility, low coefficient of friction, non-stick characteristics, negligible moisture absorption and excellent weather resistance. DS618 series has high molecular weight resins of low melt index, with low extrusion temperature, high extrusion speed which is 5-8 times of ordinary FEP resin.
Conformable with Q/0321DYS 003

Application
Mainly in the MTR transport vehicles, automatic switching equipment, well test equipment, flame alarm systems, high-rise building, fire regional wires, cables, computers, communication networks, electrical fields, particularly applicable for high-speed extrusion small-caliber wire insulation material.It is more economical when used in where no high stress cracking resistance is required.
Attention
The processing temperature should not exceed 420℃, to prevent toxic gas from releasing.
Package, Transportation and Storage
1.Packed in plastic bag of 25kgs net each.
2.Stored in clean, cool and dry places,to avoid contamination from foreign substances such as dust and moisture.
3.Nontoxic, noninflammable, inexplosive, no corrosion, the product is transported according to non-dangerous product.
