Specialty Elastomers for Diaphragms

Dia•Com has developed a range of Specialty Elastomers that provide Elastomeric solutions to difficult applications & environments. These materials provide properties that are not found in other materials and can be used in the harshest of uses.

 

EB-6009:     A Bio-Diesel Resistant ECO type compound usable to 195°F (90°C) with excellent sensitivity and long term Bio-Diesel resistance
ED-6010:   A Chemically resistant High Fluorine FKM designed for resistance against a variety of acids, alkalis & organic materials.
ED-6507:   A FKM compound with long term Low temperature & Fuel Resistance
ED-6012:   A FEPM type with out standing Chemical resistance even at high temperatures. This material is only eclipsed in in its Chemical inertness by FFKM.
ED-1002-EXPB:   A FFKM material that has been specially designed for easy manufacturing and  adhesion to Fabric reinforcement. No other polymer type has the chemical or heat resistance of this class of the polymer.
