  • Silicone composition and process useful for improving the crease resistance and abrasion resistance of airbags, intended for protecting a vehicle occupant
    Patent number: 10676574
    Abstract: The general field of the invention is that of silicone coating compositions, in particular those of two-component or multi-component type, that can be crosslinked by polyaddition or hydrosilylation reactions to produce a support coated by a silicone elastomer as a thin layer. These silicone compositions, when they are crosslinked, are suitable, inter alia, as coatings, for example for the protection or mechanical reinforcement of various textile substrates such as for example fibrous, woven, knitted or nonwoven supports. The targeted objective is to provide a silicone elastomer coating composition that can be crosslinked by polyaddition reactions and that is useful in particular for applications in the field of inflatable safety bags for vehicles, or airbags, having, after crosslinking, optimum properties in terms of adhesion, thinness, lightness and crease and abrasion resistance, but also good mechanical properties. This silicone coating composition should also be easy to use and to apply.

  • Polymer separator for a lithium battery
    Patent number: 7642012
    Abstract: A separator for a battery in lithium. The separator is a thick membrane, of around 60 to 120 ?m in polyvinylidene fluoride copolymer, which has considerable porosity, of around 50 to 90%, with pores of size between 1 and 10 ?m. With these characteristics, it is possible to optimize the operation of a battery with an electrode in, e.g., Li4Ti5O12, in particular for rapid charges and discharges, in other words in power applications.
