A biodegradable film is prepared from a composition that includes a copolyester obtained by extrusion reaction of a branched aliphatic-aromatic copolyester derived from monomer a, monomer b, monomer c and monomer d with an organic peroxide. The film can be completely degraded into small molecular products such as carbon dioxide, water and the like under natural or composting conditions. Moreover, the film can be prepared having a thickness of 4-50 μm as required, and its mechanical properties can reach the same level as or even better than those of LDPE film.

High strength ultra-thin biodegradable film and preparation method thereof

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.

Flame-retardant thermoplastic material and expanded beads thereof

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.

Flame retardant, composite flame retardant, flame retardant antistatic composition and flame resistant method

A polyethylene composition comprising an ethylene/&#x3b1;-olefin copolymerized linear low density polyethylene, wherein the polyethylene composition has a Mw of from 100,000 g/mol to 200,000 g/mol, a Mw/Mn of from 4.0 to 9.0, a Mz/Mw of from 4.0 to 7.0, and a Mz+1/Mw of from 4.5 to 13.5, is provided. A film formed of the polyethylene composition is also provided.
