The invention relates to a flame-retardant thermoplastic material, comprising thermoplastic base resin, a flame retardant, and an optional antioxidant, wherein the flame retardant comprises a complex of phosphine oxide and a transition metal salt. The invention also relates to flame-retardant thermoplastic expanded beads. A foam molding prepared from the flame-retardant thermoplastic expanded beads has good flame-retardant and antistatic properties, has excellent mechanical properties and is widely used.

An antistatic composition contains an ambient-temperature molten lithium salt dihydrate, and one of a polymerizable compound, a plastic resin, an elastomer and an adhesive resin in which the lithium salt dihydrate is dispersed. The lithium salt dihydrate contains two types of lithium salts with different molecular weights from each other. The two types of the lithium salts are selected from a group of lithium salts each containing an anion having a fluoro group and a sulfonyl group.

A lower part protection film for an OLED panel is provided. More particularly, a lower part protection film for an OLED panel, having a significantly improved recognition rate of an alignment process, being capable of preventing generation of static electricity through an antistatic treatment, and having excellent adhesion to an OLED panel at the same time, and an organic light-emitting display apparatus including the lower part protection film for an OLED panel are provided.

The present invention refers to a flame retardant comprising a complex formed by phosphine oxide and transition metal salt, wherein has good flame retardant property. The present invention also refers to a composite flame retardant and flame retardant antistatic composition. The present invention also further refers to a flame resistant method, which adds the abovementioned flame retardant, composite flame retardant or flame retardant antistatic composition into the material, so that said material has flame retardance or flame retardance and antistatic, and has excellent mechanical properties.

The present invention relates to a method for preparing a graft copolymer complex, a copolymer complex prepared by the method, and a thermoplastic resin composition comprising the copolymer complex, wherein the method comprises emulsion-polymerizing a conjugated diene-based polymer, an aromatic vinyl-based monomer, and an alkyl (meth)acrylate-based monomer to prepare a graft copolymer latex; and adding an imidazole-based ionic compound to the graft copolymer latex and coagulating the same.

A lower part protection film for an OLED panel is provided. More particularly, a lower part protection film for an OLED panel, having a significantly improved recognition rate of an alignment process, being capable of preventing generation of static electricity through an antistatic treatment, and having excellent adhesion to an OLED panel at the same time, and an organic light-emitting display apparatus including the lower part protection film for an OLED panel are provided.

In a pencil lead manufactured through a baking step regardless of being a black lead or a colored lead, the mechanical strength of the pencil lead is further increased by coating a surface thereof with a resin. A pencil lead includes a baked lead body whose surface is covered by a covering layer made of resin that has a scratch hardness of HB or greater. The scratch hardness of the resin as a subject resin is defined as a lowest hardness index of a tester pencil that is able to form an indentation on a surface of a horizontal flat plate coated with a 5-m thick film of the subject resin, when the surface is scratched by the tester pencil being pressed onto the surface at an angle of 45 with a load of 7.355 N.

Provided is an antistatic material that contains a mixture of first alkoxysilane that contains at least one alkoxy group and at least one polymerizable organic functional group, second alkoxysilane that contains at least one alkoxy group and does not contain a polymerizable organic functional group, a solvent, an acidic catalyst, and an ionic compound.
