Varglas Nylon Untreated Sleeving

Varflex_Nylon_Sleeving

Varflex Nylon Untreated Sleeving is a flexible, protective sheathing that exhibits outstanding toughness and abrasion resistance. It is braided from high- tenacity nylon yarns that have been light and heat stabilized, have low dry-heat shrinkage (6%) and were designed specifically for industrial end uses. Of the 17 standard sizes of Nylon Untreated Sleeving offered by Varflex, ten of them are available both in standard wall (Type 94) and a heavier wall (Type 94H). Type 94H is identical to Type 94 except heavier nylon yarns are used, resulting in wall-thickness increases, depending upon inside diameter. The seven other standard sizes are supplied in single wall thicknesses and do not carry a type designation. (See Tables below.)

Specifications

Varflex Untreated Nylon Sleeving conforms to Defense Supply Center Richmond's Commercial Item Description (CID) A-A-59301 (latest revision) covering "Sleeving, Textile, Braided, Synthetic Polymer", and is made from polyamide (nylon) yarns conforming to Military Specification MIL-C-572 (latest revision), Type P (polyamide), Form Y (yarn).

Applications

Varflex Nylon Untreated Sleeving is intended for use as mechanical protection in consumer, commercial, and industrial applications where flexibility, abrasion resistance, and toughness are required. Although not intended as primary electrical insulation, its suppleness and expandability make it the ideal choice, and contribute to its extensive use, as secondary insulation in wire harness assemblies where its ease of installation over irregular shapes and wire bundles provides definite assembly advantages

Sizes

Types & Classes

Coated sleeving is categorized by the type of coating, base fabric material, dielectric breakdown voltage, temperature index, and inside diameter as follows:

Type 2

A flexible treated sleeving made from inorganic-base yarns such as fibrous glass and impregnated or coated with an insulating material which can be shown by applicable experience or accepted test to have at temperature index of 130 (continuous use at 130°C)

Type 3

A flexible treated sleeving made from inorganic-base yarns such as fibrous glass and impregnated or coated with an insulating material, such as polyvinyl chloride, which can be shown by applicable experience or accepted test to have a temperature index of 105 (continuous use at 105°C).

Type 4

A flexible treated sleeving made from inorganic-base yarns such as fibrous glass and impregnated or coated with an insulating material, such as silicone resin or polytetrafluoroethylene, which can be shown by applicable experience or accepted test to have a temperature index of 200 (continuous use at 200°C).

Type 5

A flexible treated sleeving made from inorganic-base yarns such as fibrous glass and impregnated or coated with an insulating material, such as silicone elastomer, which can be shown by experience or accepted test to have a temperature index of 200 (continuous use at 200°C).

Type 6

A flexible treated sleeving made from inorganic-base yarns such as fibrous glass and impregnated or coated with an insulating material, such as epoxies, polyesters, or acrylics, which can be shown by experience or accepted test to have a temperature index of 155 (continuous use at 155°C).
