Min-k 500 (Johns-Manville)

Min-K 500 was one of the molded grades of Johns-Manville's Min-K insulation.1 A 1990 EPA notice that published what Manville reported lists it in one entry with the other molded grades (Min-K 1301, 2000 and 500, and Min-Klad) and the flexible Min-K blankets, produced from 1958 to 1974, and describes the entry as the solid form for molded Min-K and flexible blankets.1 For that whole group, not for Min-K 500 alone, it gives 5 to 20% asbestos fiber and 70 to 80% colloidal silica, with up to 20% titanium dioxide, up to 10% carbon black and up to 6% phenol-formaldehyde resin among the other ingredients.1

An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, lists Min-K 500 as a block made by Johns-Manville from 1958 to 1974.2
