摘要:
The present invention provides a sheet molding compound consisting in a sandwich structure comprising a central layer of reinforced uncured heat hardenable sheet molding compound; and two outer layers of a release film having low permeability to hydrocarbons comprising at least one layer (i) of a polyamide/polyolefin alloy having a polyamide matrix and at least one layer (ii) of a polyolefin.
摘要:
The invention relates to antistatic wrapping films comprising at least one layer made of polyamide or of an alloy of polyamide and of polyolefin. The antistatic additive is a polymer containing polyamide blocks and polyether blocks. They are particularly useful for wrapping expandable polystyrene which contains pentane.
