Abstract:
Multilayered extruded thermoplastic profiles are disclosed. The profiles are useful for decorative extruded louvers exhibiting a polished metal-look. The metal-look is achieved by the use of a limited amount of powdered aluminum metal having particle size of 50 microns or less, combined with an effective amount of nacreous pigment. The invention provides a multi-layer extrudate having the appearance of polished metal in the appearance layer in combination with an opaque or clear base layer. The preferred embodiment is a co-extruded polyvinyl chloride. Preferably, the appearance layer comprises 100 weight parts of rigid polyvinyl chloride as the thermoplastic matrix, a combination of from 0. 05 to about 4 parts by weight of aluminum particles having an average particle size of from 10-40 microns, from 0. 1 to 5 weight parts of titanium dioxide coated mica pigment or colored version thereof, and optional organic or inorganic coloring pigment(s).
