[nanoPost] Nanosilicone elastomer for industrial molding compounds

Company Germany  

 
The product is a transparent, low-viscosity dispersion of SiO2 nanoparticles in Polymer , a vinyl-terminated basic silicone polymer. By adding the product to a system already filled with fumed silica, the mechanical properties can be substantially improved with only a slight increase in viscosity.

The different positive properties of the product can develop their strengths either individually, or in combination. If, for example, high heat-conducting, optimum impregnation and increased insensitivity to pressure are required for the casting and sealing of electronic components, a useful side-effect is transparency, e.g. for optical tests.

The product improves the working conditions and the quality of the silicone elastomer when producing industrial molding compounds. Another advantage is that the material is also transparent. With dental molding compounds, the product further increases the tensile strength and tear resistance of a highly filled system – but without any significant increase in viscosity.

The product makes it possible to produce elastic gels with a relatively high filler load, and this in turn enables improved mechanical properties – without the use of plasticisers and thus without the potential disadvantage of "bleeding". This means that there is an innovative alternative for casting or sealing pressure sensitive substrates to systems that can endure almost no mechanical strain. An alternative with additional positive features: elastic, transparent and shock-resistant despite a high filler load. Industry has been dreaming of a material with such properties!
