Material Specification No. 1001-20

Raw materials are not sold separately, please contact the sales department for any special requirements.


The 63-20 jacketing is ideal for applications that are high-flexing and need lasting protection from abrasion.

The 63-20 jacketing is a 20-mil (0.02”) thick PVC film that is abrasion resistant, corrosion resistant, fluid resistant, UV stabilized, and contains anti-fungicide. The jacketing material meets specification MIL-I-631D, Type F, Form S, as well as MIL-I-631, Grade C, Class I, Category 1. The 63-20 jacketing has an operational temperature of -4°F to 221°F (-20°C to 105°C). The jacketing also has a dielectric rating of 700 volts/mil, handling up to 14,000 volts, a dielectric constant of 7.0 (1 kilocycle), and a dissipation factor of 0.14 min. (1 kilocycle). 63-20 can be configured for round, flat, or rectangular applications, can be heat sealed together with most closure systems, and can be equipped with an internal overlap flap to meet ground-based military application requirements.
