摘要： A one component precursor for the polymeric foam (OCF) composition comprising a very low amount of free monomeric MDI. The present OCF composition may be obtained without any free MDI removal step, and without the addition of extra solvent to compensate for the substantially lower amount of free MDI, compared with traditional compositions. The present composition comprises a source of free NCO of functionality of at least 2.6, a tri- or higher functional alcohol, all polyols being characterized by a rather low molecular weight and at least a specific mono-functional alcohol as well as an isocyanate end-capped prepolymer of toluene diisocyanate (=end capped TDI). The OCF composition is suitable for being dispensed from a pressurized can with a blowing agent.

摘要： The invention concerns an improvement to a grommet, preferably for a tilting valve of a container, which increases the protection against moisture diffusion and uptake, in order to avoid blocking or leaking of the valve. The valve comprises a grommet (1) having at least one part made (1A) of non-thermoplastic rubber and another part (1B) made of a thermoplastic material, the latter being in contact with the content of the container. This valve is preferably made by the dual injection technique. The non-thermoplastic rubber may be EPDM or Santoprene and the thermoplastic rubber may be Trefsin.
