CENTELLEN^® NP 3860

Special material with excellent chemical resistance to refrigerants.

CENTELLEN^® NP 3860 is a special gas tight material designed for applications with refrigerants.

Basis

Aramid fibers bonded with NBR and CR.

Areas of application

This material is resistant to most refrigerants like freons, dichloromethane, hydrocarbons like oils, glycole as well as weak alkalines and organic acids.
The gasket material is only partly suitable for ketone and ester.
