  • Publication number: 20170037235
    Abstract: A thermoplastic composition comprises a thermoplastic resin (e.g., PVC) and less than 4.0 parts of a core-shell impact modifier per 100 parts by weight of the thermoplastic resin, wherein the core-shell impact modifier has a rubber content of at least 90%. A core-shell impact modifier composition comprises core-shell impact modifier particles having a rubber content that is greater than 92 wt % of the core-shell impact modifier particles. Articles of manufacture made from the thermoplastic compositions are also disclosed.

  • Patent number: 5148765
    Abstract: An improvement in the preparation of printed circuits comprises inserting a deformable layer between the phototool or support layer, and the solder mask. The deformable layer provides a uniform, integral and relatively thin coating of solder mask over circuit components, and results in higher-quality solder joints and lower rejection rates for finished boards.
