Thermomat was a Johns-Manville asbestos-phenolic molding material that came as felt sheet and as tape.1,2 In sworn answers in two lawsuits, in 1969 and 1970, J-M listed it as aviation insulation, "a nonwoven long fiber asbestos felt saturated with phenolic resin," and listed Thermomat Tape as a molding compound "designed for tape winding; used to create components and parts that withstand tremendous heat and pressure."3,4
The sources give different years. Asbestos, the industry's trade journal, named Thermomat, "a newly developed moulding compound," as a new J-M product in its review of 1960.5 An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, gives it as made from 1963 to 1969.6 A 1990 EPA notice that published what Manville reported gives 1963 to 1970.2
The 1990 notice, in an entry for Thermomat alone, gives asbestos fiber at 90 to 98% and phenol-formaldehyde resin at 2 to 5%, in sheet or tape form.2 The magazine's review of 1963 described one grade, Thermomat 383, as "an asbestos-phenolic molding mat in felt form, developed to provide exceptionally lightweight thermal shielding and high strength to weight ratio."1 J-M's employee magazine said early in 1964 that TX Fiber, "available in tape and sheet form as Thermomat," reinforced plastic heat shields and rocket thrust chambers operating at 6000F and above.7
