A polypropylene composition, a preparation method thereof, and a film or a sheet prepared from the polypropylene composition and use thereof. The composition includes 45 parts to 75 parts of a polypropylene, 10 parts to 35 parts of an elastomer, 5 parts to 20 parts of a polyethylene, 0.1 parts to 0.5 parts of an antioxidant, and 0.1 parts to 0.5 parts of a lubricant. A half peak width of a crystallization peak of the polypropylene is 5&#xb0; C. to 10&#xb0; C., and a peak temperature of the crystallization peak of the polypropylene is 105&#xb0; C. to 115&#xb0; C. The polypropylene composition has a good tenacity, especially a&#x2212;30&#xb0; C. low-temperature impact performance. The film or the sheet prepared from the composition and applied to automotive interior parts, can enable the external accessories not only to be less likely to generate sharp fragments while being strongly impacted, but also to have a matte characteristic.

The present invention relates to an airbag door for instrument panel and its manufacturing method. A passenger side airbag (PAB) door for instrument panel includes a substrate with airbag opening, skin layer and foam layer, a PAB door reinforcement board which covers the airbag opening is connected to the instrument panel substrate. This PAB door reinforcement board is a cellulosic composite material board which is soaked by thermoplastic plastic or thermoplastic elastomer, formed through thermoforming. In present invention, the turnover and movable portion of the airbag door is lighten greatly. The airbag door with the light composite material can prevent the windshields from being broken effectively when the airbag deploys sufficiently and impacts against the windshields.

An automotive interior trim for improving deployment safety of seamless passenger airbags for instrument panel is disclosed. The interior trim, mounted on an deployment opening of an airbag module of a framework for a instrument panel, includes a framework with an airbag deployment opening for a instrument panel, an airbag cover covering the airbag deployment opening, a foaming interlayer, a surface layer, and a netlike additional layer which is integrally combined with the foaming interlayer after penetrated by a foam material. When the airbag bursts, the airbag cover is opened outwards and the surface layer of the instrument panel is torn, and the foaming interlayer is torn thereupon too. Under the effect of the netlike additional layer, the foam in the foaming interlayer is fixed by the additional layer, thereby avoiding crumb and hard particle production and improving the deployment safety of the airbag greatly.
