Application Details

HDK® H2000 is applied as a reinforcing filler in elastomers, mainly silicone-elastomers. It is used as a free flow additive in the production of technical powders and as additive in antifoam agents. HDK® H2000 is not suitable for pharmaceuticals, food and feed. A good dispersion of HDK® H2000 is a must to assure optimum performance.
