The CBC Difference

The CBC difference includes our original lap-seam sealing process and the use of 20 mil. polyurethane material that is almost indestructible and helps ensure against contamination due to accidental puncture or tear.

CBC uses a highly durable "lap seam" seal for the majority of our seams, and an even superior "cut/weld/strip seam" seal for high risk areas. Because your reputation, research or production should not risk being compromised!    (See, "Pull Test" and "Puncture Demonstration" videos below.)
