Beta cloth Beta cloth Beta cloth is a type of fireproof silica fiber cloth used in the manufacture of Apollo/Skylab A7L space suits, the Apollo Thermal Micrometeoroid Garment, the McDivitt Purse, and in other specialized applications. Beta cloth consists of fine woven silica fiber, similar to fiberglass. The resulting fabric will not burn, and will melt only at temperatures exceeding . To reduce its tendency to crease or tear when manipulated, and to increase durability, the fibers are coated with Teflon. A tight weave of Beta cloth makes it more durable against atomic oxygen exposure. Its ability to resist atomic oxygen exposure
