GENIOPLAST® GUM is an ultra-high molecular weight polydimethyl siloxane (silicone gum) with low volatiles content.
When added to thermoplastic resin systems at 0.1% to 1%, improved processing and flow of the resin is expected, including less extruder torque, less extruder die pressure, faster throughput, reduction of melt viscosity and better mould filling. At higher addition levels of GENIOPLAST® GUM, 1% to 5%, also improved surface properties are expected, including release, lubricity, slip, improved surface gloss, lower coefficient of friction, and greater mar and abrasion resistance. GENIOPLAST® GUM can also improve burning characteristics of thermoplastic resins, especially when applied in combination with halogen-free flame retardant fillers. GENIOPLAST® GUM is expected to give improved benefits compared to conventional lower molecular weight siloxane additives, e.g. less screw slippage, improved release, a lower coefficient of friction, fewer paint and printing problems, and a broader range of performance capabilities.
Comprehensive instructions are given in the corresponding Material Safety Data Sheets. They are available on request from WACKER subsidiaries or may be downloaded via WACKER web site http://www.wacker.com.
Due to its high viscosity, GENIOPLAST® GUM is incorporated into thermoplastic resins preferably by batch technologies.
Confirmation of food contact compliance for GENIOPLAST® GUM is available upon request.

The 'Best use before end' date of each batch is shown on the product label.
Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
