Although Neuburg siliceous earth is most commonly used in elastomers, there are applications where other products have to be used. These include products where the gas or water vapor permeability has to be as low as possible. With Struktosil 45 AM, a talc with amino functionality, is offering a functional filler to improve the barrier effect in elastomers while maintaining a good compression set.
Different functional groups such as vinyl, methacrylic, alkyl, etc. can be applied to the base material for surface modification. It is also possible to use other grades as base material.
