    Abstract: A reflector reflects incident light and comprises crystalline plastic in which a crystal region and an amorphous region are mixed, wherein the amorphous region includes a plurality of orientation layers comprising amorphous particles that are oriented in a predetermined direction. The reflector, which has high reflectance, is formed by extending a crystalline plastic material exhibiting a superior extensibility to extend the amorphous particles in the amorphous region in the predetermined direction so as to form a plurality of extension layers in the amorphous region. Since a reflector having a superior performance with a very improved reflectance can be provided due to a high diffuse reflectance by the extension layers in the amorphous region without a foaming process or an additional additive to increase the reflectance, the manufacturing process of the reflector is simplified and the manufacturing cost is reduced so that productivity can be greatly improved.

  • Publication number: 20130035468
    Abstract: Provided is a thermoplastic resin having excellent thermal conductivity, in which thermoplastic resin a change in number average molecular mass caused by progress of polymerization occurring when the thermoplastic resin material is melted and a change in thermal conductivity caused by the change in number average molecular mass are low. The thermoplastic resin has (A) a specific structure and (B) ends of molecular chains sealed by a monofunctional low molecular weight compound. The resin itself has excellent thermal conductivity. The change in number average molecular mass becomes small during melting of the thermoplastic resin material, so that the change in thermal conductivity of the resin itself becomes small.
