  • Functionalized membrane for a chamber for encapsulating cells producing at least one substance of therapeutic interest and bioartificial organ comprising such a membrane
    Patent number: 9005960
    Abstract: The present invention relates to a functionalized semi-permeable membrane composed of a porous biocompatible support pretreated so as to increase the surface energy thereof and characterized in that it includes at least two layers, each having a hydrophilic polymer and at least one biological active molecule, and to the use thereof in particular for producing a bioartificial organ.

  • Eco friendly crosslinked flame retardant composition for wire and cable
    Patent number: 8263674
    Abstract: An eco friendly radiation cross-linked composition is described that demonstrates excellent resistance to fire and high temperature along with good mechanical properties. The composition which is based on a blend of EVA with a LLDPE, is free of monomer such as vinyl co-agent for radiation cross-linking. The halogen free flame retardant composition is a mixture of 20 to 90% by weight of magnesium hydroxide (powder A) and 90% to 20% of powder B. Preferably the powder B is a double salt of magnesium carbonate and calcium carbonate and the magnesium hydroxide has a specific surface treatment. In addition, 0.5 to 5 parts of flame retardancy agents are selected from talc, zinc borate or molybdate derivative. The chemicals used here reduce toxicity in the environment and do not release toxic chemicals to air and soil during fire. The flame retardant cross-linked polyolefin composition is particularly useful for insulating wires and cables.

Preferably the powder B is a double salt of magnesium carbonate and calcium carbonate and the magnesium hydroxide has a specific surface treatment. In addition, 0.5 to 5 parts of flame retardancy auxiliary agents are selected from talc, zinc borate or molybdate derivative. The chemicals used here reduce toxicity in the environment and do not release toxic chemicals to air and soil during fire. The flame retardant cross-linked polyolefin composition is particularly useful for insulating wires and cables.
