CENTELLEN® WS 3820

Universal gasket grade with high mechanical strength.

CENTELLEN® WS 3820 is a material which fulfils the requirements for sealants of the natural gas industry. The gasket sheets feature a thin layer of anti-stick coating. The universal chemical properties are not effected by this.

Basis

Aramid fibers bonded with NBR.

Areas of application

The material is suitable for hydrocarbons like oils or solvents, alcohols, glycols, aqueous solutions, water and steam up to 200°C. Weak alkalines and organic acids are also among possible applications.
This material is limited suitable for ketones and esters, chlorinated solvents, as well as strong alkalis and inorganic acids.
