PRODUCTION OF DIFFUSING DISCS USING SHEETS OF GLASS FIBER-FILLED THERMOPLASTICS

摘要

Diffusing discs are produced by incorporating glass fibers into thin sheets of thermoplastic resin. The glass fibers are incorporated into the resin by conventional methods and formed into sheets according to well known thermoplastic forming processes. The sheets so produced display the ability to act as diffusing discs without any special surface preparation.
