Insulation Materials Characteristics - Fluorocarbons

1. KYNAR
KYNAR's advantages include: Exceptional chemical resistance, high tensile strength, abrasion resistance, cut through and UV resistance. Additionally, it is highly flame resistant and produces very little smoke in the presence of flame. For applications requiring increased flexibility and stress crack resistance, KYNAR FLEX® copolymers are recommended.

 
2. SOLEF
SOLEF® is a registered trademark of Soltex, which is a subsidiary of Solvay, a manufacturer of Vinylidene Fluoride-based resins. Solef has a number of grades which are widely being used in fiber and overall jacketing applications. It's properties are very similar to KYNAR's.

 
3. TEFLON® PFA
Teflon® PFA possesses some of fluorocarbon's best properties. Its high temperature rating of 250°C, low temperature of -65°C and dissipation factor of .0002 equal or better most of the other fluorocarbons' properties. However, it does not possess the thermoset properties of TFE which limits it to a select group of applications. Although it can be processed in long lengths, PFA's high material cost has prevented it from gaining widespread use.

 
4. TEFLON® FEP
Teflon® FEP is the most commonly used fluoropolymer currently because of its excellent processing characteristics and wide applications range. Although it is not a thermoset, this material does have high flame resistance. Hence, its usage in plenum cable and military applications has been steadily increased as pricing and processing improve. FEP can also be "foamed" for improved data transmission characteristics.
 
5.

ETFE TEFZEL and ECTFE HALAR
Although lacking many of FEP's excellent electrical properties, ECTFE and ETFE posses better flexibility and mechanical strength than either PFA or FEP. Additionally, ECTFE & ETFE can become thermoset by the irradiation method. ECTFE can also be "foamed" for improved data transmission characteristics and is frequently used for the purpose of weight reduction.
