摘要:
Thermoplastic resin compositions suitable for laser welding are described in which black colorants are added. These colorants constitute amine salt of anthraquinone dyes. Additional dyes, coloring agents, and a variety of other materials may be added. These compositions demonstrate outstanding mechanical and chemical properties once laser-welded.

Thermoplastic resin compositions suitable for laser welding are disclosed, which include a mixture of neutral anthraquinone blue dye with other red dye to absorb visible light with wavelength less than 700 nm and transmit a laser beam with wavelength at 800 nm to 1200 nm and to enhance weldability.

摘要:
Laser weldable polyester resin compositions comprising thermoplastic polyester and an α-methylstyrene copolymer, and, optionally, one or more of inorganic reinforcing agent and/or filler and other additives and a process for laser welding objects made from the compositions. The compositions have improved melt flow and rigidity at elevated temperatures.
摘要:
A surface protective film which can be used in the production of components associated with a liquid crystal display such as a polarizer to improve productivity and yields since no air bubbles are trapped when stuck to a substrate having unevenness in the surface and since the adhesion is low and a change of the adhesion with the passage of time is small and which can be highly transparent and improve inspectability by using a polyester film having little particles as a base material. It is treated by an antistatic agent or a release agent the surface of the surface protective film opposite to the surface in which the adhesive layer is formed, as a result, control of static electrification in case the surface protective film is peeled off and removal of the dust adhering to the surface can be made easy.
摘要:
A laser welding method includes emitting two laser beams along a weld line from an upper surface side of a workpiece, the two laser beams being transmitted through different optical fibers and having in-focus spot diameters of 0.3 mm or larger; emitting the laser beams such that a leading laser beam of the two laser beams and a trailing laser beam of the two laser beams are each inclined toward a direction in which welding proceeds at an incident angle with respect to a direction perpendicular to an upper surface of the workpiece, the leading laser beam being ahead of the trailing laser beam on the upper surface of the workpiece in the direction in which welding proceeds, the trailing laser beam being behind the leading laser beam; and setting the incident angle of the leading laser beam to be larger than the incident angle of the trailing laser beam.
