Product listing


  • Modifier 705

    Modifier 705 and Modifier 715 are SiH-terminated polydimethyl siloxanes which are used as plasticizers in addition-curing silicones. Due to their difunctional structure, these products do not react by crosslinking, but by extending the chains of vinyl-terminated silicone polymers (Polymer VS). Use of the modifiers reduces the crosslinking density and therefore the elastomer hardness.
