Abstract: L'invention concerne un procédé de préparation d'un caoutchouc naturel de fond de tasse qui comprend l'extrusion d'un mélange d'un coagulum de caoutchouc naturel de fond de tasse et d'un agent de blanchiment du caoutchouc naturel dans une machine à vis sans fin équipée d'un fourreau, dans lequel tourne la vis, et d'une filière à trous en bout de vis, procédé dans lequel : a) le mélange formé du coagulum et de l'agent de blanchiment est comprimé à une température supérieure ou égale à 110°C et inférieure ou égale à 210°C dans le fourreau, b) une détente éclair adiabatique à une pression différentielle supérieure ou égale à 30 bars est réalisée en sortie de filière. Le procédé permet de réduire la teinte du caoutchouc naturel de fond de tasse.

Abstract: A process for the continuous preparation of silicone rubber base compositions using an in situ silica treatment and twin-screw extruder technology comprising (a) introducing a hydrophobing treating agent (C), a diorganopolysiloxane containing at least two alkenyl and/or alkynyl groups, and optionally water into a first static mixer and then introducing it in a first twin-screw extruder; (b) adding reinforcing silica filler at a temperature of 20-80°C and providing at least one vent to the atmosphere up and/or downstream of the reinforcing silica filler (B) entry port to allow gases present to escape; (c) mixing in the extruder; (d) further mixing in a residence zone; (e) vacuum stripping at a temperature of at least 100°C; and (f) introducing component (C) either into the twin-screw extruder between steps (c) and (d) and/or during step (d) to dilute and further hydrophobically treat silica. Also resulting compositions produced therefrom.

Abstract: A system and method for dispensing thermal management and/or EMI mitigation materials is provided. The system and method includes online remixing prior to dispensing the thermal management and/or EMI mitigation materials. The system includes an online remixer(104) configured to be operable for receiving a supply of the thermal management and/or EMI mitigation material including one or more functional fillers within the matrix, remixing the one or more functional fillers including filler settlement, if any, within the matrix prior to dispensement of the thermal management and/or EMI mitigation. The remixing may reduce the filler settlement, if any, within the matrix and thereby allow for improved viscosity and flow rate of the thermal management and/or EMI mitigation material.
