GLOXIL iM16k A

Hoffmann Mineral has been working in cooperation with 3M for years to develop products based on hollow glass microspheres. The product is based on the iM16k, modified with an amino function. The main field of application is the production of thermoplastics with demands for low density and low weight of the finished product. The functionalization allows a better integration of the lightweight filler, leading to an improvement in the strength of the finished product.

Thanks to the exclusive cooperation with 3M, it is also possible to use other grades (size and stability) of 3MTM Glass Bubbles. Different functional groups such as vinyl, methacrylic, alkyl, etc. can be applied to the base material for surface modification.
