Glastic Grade 1125 (Corrosion Resistant for Fume Hood Liners, Spray Booths, etc.)

Glastic® Corrosion-Resistant Panels are ideal for applications where resistance to both flame, and the splash or spill of laboratory chemicals is important.
These asbestos-free, fiberglass reinforced polyester resin sheets offer a particularly low smoke generation when exposed to flame. Grade 1125 is Underwriters laboratories, Inc.® classified with a flame-spread rating of 25.

This material has very low water absorption characteristics, along with excellent splash and spill resistance to acids, weak bases and aliphatic hydrocarbons.

Panels can be manufactured in sizes of 3 x 6 feet and 4 x 8 feet. Sheet thickness ranges from 1/16 inch to 1/2 inch. Call us for current availability.
