Compressed sheets manufactured with organic
and mineral fibers mixed in a rubber matrix. The product BELPA®
CSA - 25 is suitable for a wide range of applications with low levels
of responsibility. This material has low gas permeability and cost,
that makes this asbestos-free product suitable for most common uses
(air, water, some oil and heavy grease). Material specially designed
for water, air, gas and moderated applications.
