Style 1938 is an 8 harness satin weave fiberglass fabric weighing 26.8oz/sq yd and has a thread count of 45 x 36 ends/inch. Style 1938 uses the yarn ECK 18 1/0 in the warp and ECG 37 1/2 in the fill and is 0.026" thick. We have a half a truck load of this cloth heat cleaned (carmelized) and in the greige in 29.5, 38 and 38.5" widths with rolls up to 380 yards. The widths are the area between the outer 3/4" woven part. For example a 38.5" wide style 1938 will be 40" from edge to edge of the cloth with 3/4" on each side a different more secure weave. This cloth can be used for pipe wrap around insulation - heavy tough cloth and with the complex sewn edge wont fall apart and priced way below market price. The greige still has the pva release agent to make it slippery for silicone rubber to flow in easier. The heat cleaned finishes CS-210 and CS456 have all volatiles removed with heat cleaning or the carmelization process so that the heat cleaned 1938 fiberglass cloth can take temperatures up to 1500 deg Farenheit easy. E-Glass fiberglass cloth keeps 50% of it's tensile strength up to 700 Degress Farenheit, 25% at 900 Degrees Farenheit, softens around 1500 Degrees Farenheit and melts around 2,000 degrees.
