TEGOMER® V-Si 4042 is a solvent free, reactive polysiloxane to be used as an additive for thermo-plastic compounds as well as for EPDM compounds with peroxide curing.
Typical Applications
- Serves as a processing aid for highly loaded compounds containing carbon black (CB) or mineral fillers, like aluminium or magnesium hydroxide
- Enhances the flame-retardant properties of the compound
- Is used to produce halogen free flame-retardant polyolefin and elastomeric compounds for cable applications
- Is suitable for x-PE applications. By thermally initiated crosslinking reactions it can be introduced permanently into polymeric resin
- As a processing aid TEGOMER® V-Si 4042 improves the extrusion of EPM / EPDM compounds without changing the rubber articles physical properties
