| Geniomer thermoplastic silicone elastomer from Wacker combines the typical properties of silicones with the thermally moldable advantages of a thermoplastic. |
Munich, Germany–based Wacker Silicones has developed a new process
for manufacturing a silicone compound. The resulting product, called Geniomer,
has unique properties and characteristics.
It is a polydimethylsiloxane urea copolymer that contains both hard and soft
blocks of material.
Its unique property profile stems from the combination of inorganic and organic
components. A silicone forms the basis of its soft segment, which is responsible
for the product’s elasticity. An organic group builds the corresponding
hard segment, which offers strength and heat stability.
Wacker uses a physical curing process instead of the traditional catalyst-based
technique. Because no catalysts are used, the polymer has no byproducts or organic
volatiles. It has very high purity. These characteristics make it ideal for
use in medical applications such as tubing.
Available in several grades, Geniomer is paintable, and has good slip and release
properties, low temperature flexibility, and high tensile strength.
Working closely with its customers, the company is currently running a project
to open up new markets and application fields for thermoplastic silicone elastomers.
Potential uses range from process aids for plastics, such as polypropylene,
or other materials.
