摘要： A liquid crystal polyester pellet composition comprising a first pellet and a second pellet is employed as a molding material for an injection molded article. The first pellet is a pellet comprising a liquid crystal polyester; the second pellet is a pellet comprising an organic pigment, an organic dye or carbon black and a liquid crystal polyester, and the second pellet is a pellet different from the first pellet; and a melt viscosity ratio represented by melt viscosity of the second pellet/melt viscosity of the first pellet is less than 3.2.

摘要： A polymer composition is described well suited for being combined with relatively short fibers. The fibers, for instance, can have a mean fiber length of less than 1,000 microns, such as less than 700 microns, such as less than 500 microns. The polymer formulation allows for intimate mixing with the fibers without having to use a sizing agent. In one embodiment, the composition contains a polybutylene terephthalate polymer combined with a thermoplastic polymer having lower crystallinity.

摘要： Compositions comprising post-consumer recycled (PCR) waste are described. The PCR is combined with at least one virgin resin and a propylene-based compatibilizer that enhances the blend between the PCR and virgin resin as well as improving one or more physical properties of the composition. The propylene-based compatibilizer is a reactor made thermoplastic polyolefin or a heterophasic copolymer with a semi-crystalline matrix and a rubber component. This allows for the selection of a compatibilizer that can shift the composition's physical properties based on the end use application, and provide a stronger, miscible blend.

摘要： A polymer composition that contains an aromatic polymer in combination with a tribological formulation is provided. The polymer composition may exhibit a low degree of surface friction that minimizes the extent to which a skin layer is peeled off during use of a part containing the composition (e.g., in a camera module). For example, the polymer composition may exhibit a dynamic coefficient of friction of about 1.0 or less and/or a wear depth may be about 500 micrometers or less as determined in accordance with VDA 230-206:2007.

摘要： An insulating thermally conductive resin composition (10) includes a matrix resin (1) and insulators (2). The insulators (2) are dispersed in the matrix resin and have electrical insulation. The insulating thermally conductive resin composition further includes a thermally conductive phase (3) which has a hither thermal conductivity than the matrix resin and thermally connects the insulators with each other. The thermally conductive phase (3) is composed of an organic substance. The thermally conductive phase that thermally connects the insulators is composed of the organic substance, so that the resultant insulating thermally conductive resin composition has electrical insulation while having improved thermal conductivity.

摘要： The present invention provides fluoropolymer laminates having isotropic properties. For example, an embodiment in which multiple fluoropolymer sheets having a liquid crystalline polymer oriented in the fibrous state in the melt processible fluoropolymer are laminated, despite having the fibrous LCP oriented in one direction in each single extruded sheet, makes it possible to laminate in such a way as to compensate for their orientation directions, the laminate thereby becoming isotropic as regards physical properties. The laminates also have low linear coefficient of expansion and low thermal shrinkage as well as elevated tensile modulus and low dielectric constant.
