The present invention provides an insulation film, comprising a film upper layer and a film lower layer, wherein both of the film upper layer and film lower layer are made of a PC or PET material, the PC or PET material contains a flame retardant to meet the flame retardance and puncture resistance property thereof; a film intermediate layer located between the film upper layer and the film lower layer, the film intermediate layer is made of the blends of PP and/or PE and PC and/or PET; an upper surface of the film intermediate layer is bound together with a lower surface of the film upper layer, a lower surface of the film intermediate layer is bound together with an upper surface of the film lower layer.

Insulation film and method for making insulation film

The present invention provides an insulation film (), comprising a film upper layer () and a film lower layer (), wherein both of the film upper layer () and film lower layer () are made of a PC or PET material, the PC or PET material contains a flame retardant to meet the flame retardance and puncture resistance property thereof; a film intermediate layer () located between the film upper layer () and the film lower layer (), the film intermediate layer () is made of the blends of PP and/or PE and PC and/or PET; an upper surface of the film intermediate layer () is bound together with a lower surface of the film upper layer (), a lower surface of the film intermediate layer () is bound together with an upper surface of the film lower layer ().

The present invention provides an insulation film, comprising a film upper layer () and a film lower layer (), wherein both of the film upper layer () and film lower layer () are made of a PP material, the PP material contains a flame retardant to meet the flame retardance thereof; a film intermediate layer () located between the film upper layer () and the film lower layer (), the film intermediate layer () is made of a PP or PE material does not contain a flame retardant or contains a small amount of flame retardant; an upper surface of the film intermediate layer () is bound together with a lower surface of the film upper layer (), a lower surface of the film intermediate layer () is bound together with an upper surface of the film lower layer ().

The present invention provides an insulation film and a method for making the insulation film, comprising a film upper layer and a film lower layer, wherein both of the film upper layer and film lower layer are made of a heat conduction plastics material, the heat conduction plastics material contains a heat conduction additive; and a film intermediate layer located between the film upper layer and the film lower layer. The film intermediate layer is made of a heat conduction plastics material, and the heat conduction plastics material contains a conductive additive An upper surface of the film intermediate layer is bound together with a lower surface of the film upper layer, and a lower surface of the film intermediate layer is bound together with an upper surface of the film lower layer.

A flame retardant composition includes a polymeric base material, a non-halogenated flame retardant material and a synergist material present in a concentration of about 1 percent by weight of the composition. The synergist is substantially free from metal oxides. The flame retardant composition achieves a flammability rating of at least V-2 when tested in accordance with UL testing conditions.
