ABSTRACT:
Insulation sleeving, such as for providing thermal and/or electrical insulation for cables and cable connections, of the type comprising an inner sleeve of woven synthetic organic or inorganic fiber, such as fiberglass, and an outer coating of silicone elastomer. The woven fiber of the inner sleeve has a substantially open weave, i.e., the number of picks per centimeter is in the range of between about 2 and 9, andthe silicone elastomer of the outer coating has a reduced modulus of elasticity, such as between about 0.5 and 3.5 MPa at 100 percent elongation, and an increased tear strength, such as between about 5 and 45 KN/m. Insulation sleeving is elastically expandable to an extent such that its diameter can be increased up to twice its original unexpanded dimension without materially affecting the thermal, electrical and mechanical insulation properties of the sleeving thereby enabling a standard sized sleeving, i.e., a sleeving having a certain uniform diameter, to be used in insulating any object having a substantially uniform diameter which is substantially equal to or up to twice the unexpanded diameter of the insulation sleeving. The insulation sleeving is also useful in insulating a region which presents an abrupt dimensional discontinuity, such as a cable connection.
