cohrlastic-solid-rubberThe COHRlastic® solid silicone rubber line includes specification grade, high-performance grade and electrically conductive grade products.
Solid RubberProducts range in thicknesses from .012” (.031mm) to .500” (12.7mm) in durometer, hardness from 30-70 on the Shore A scale. Materials are provided in both flat sheet stock size 36”x36” (914mm x 914mm) and flat yard goods in 36” (914mm) continuous length rolls. Temperature ratings generally range between -100°F to + 500°F (-73°C to + 260°C).

Often referred to as red rubber because the earliest offerings were all red in color, COHRlastic® solid silicone rubber also comes in clear, gray, black and green, with minimum quantity restrictions. Many COHRlastic® solid materials meet the most popular solid rubber specifications, including ZZR-765 and A-A-59588 (ZZR-765 is now a listing within A-A-59588).
