Ben-Har Acryl sleeving is manufactured by coating a lightly heat-treated braided
fiberglass sleeving with a dielectric film of thermosetting polyacrylate resin qualified
for Class F (155ºC) systems. The tough acrylate film is highly craze resistant and
will withstand severe bending without loss of dielectric properties. It is resistant
to acids and most organic solvents and compatible with a broad range of wire
enamels - acrylic, polyester, polyamide, polyimide, and polyvinylformal. By virtue
of crosslinking the acrylate, film will not flow upon application of heat.
The acrylate film is extremely tough and flexible, allowing the sleeving to withstand
rough assembly handling, mechanical stress, and resistance to cut-through. The
coating film will not flow upon application of heat. Ben-Har Acryl is resistant
to acids, alkalis, organic solvents, and aliphatic hydrocarbons. Slight swelling is
produced by aromatic solvents and chlorinated hydrocarbons. Ketones and esters
have a softening effect.
Ben-Har Acryl resists up to 10 megarads of radiation dosage with no discernible
effect. When tested in accordance with NEMA VS-1, MIL-I-3190 method B, ASTM
D-350, and UL 1441, Ben-Har Acryl burns at less than 1.33 inches per minute.
