Marimet 45 (Johns-Manville)

Marimet 45 was a Johns-Manville board.1 A 1990 EPA notice that published what Manville reported lists it in a group of asbestos calcium silicate sheets, with Marinite and its numbered grades and several other boards, produced from 1936 to 1978, and describes the group as a grey-brownish sheet.2 For the group as a whole, not for Marimet 45 alone, it gives 25 to 65% asbestos fiber, with 20 to 36% lime, 20 to 35% diatomaceous earth and 10 to 15% clay.2

An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, lists Marimet 45 as a board made by Johns-Manville from 1970 to 1981, the year of the list itself.1
