<p>The electrical-insulating pressure-sensitive adhesive tape (10C) can be produced by (1) forming a fluffy web (10) of oriented polymeric fibers, (2) simultaneously squeezing and saturating the fluffy web between rolls (14, 16) with a crosslinkable polymeric resin in a volatile vehicle, and (3) heating in an oven (22) to drive off the vehicle. The resultant tape can be produced at a cost comparable to that of paper-backed tapes while possessing tear strength, resistance to heat and electrical-insulating properties comparable to those of more expensive tapes of the prior art. </p> |
