PVC sheet foamed

 PVC sheet foamed

Sheets of PVC made foam are made by a method  of extrusion from a mix of a powder of polivinilkhlorid with the special additives providing improved properties of finished goods (crashworthiness, UV-stabilization of sheets). Foaming of plastic occurs on an output from barrel cylinder
. Internal small-meshed in regular intervals made foam structure of ready sheets containing the big percent of the smallest emptiness, gives to sheets excellent parameters of  termal protection and sound insulation.

 The made foam PVC a leaf is applied to advertising, construction, ship repair, manufacturing of guide signs. A vivid example of advertising application of it PVC of plastic can be manufacturing of assembly show-windows, exhibition stands, displays, signboards. In construction it is used for facing a facade and furnish of internal premises. Recently of the made foam PVC of plastic make furniture.

 The surface from both parties is ideal for drawing paints and self-glued пленок, approaches for external application without preliminary processing. There is an opportunity of secondary processing.

 The basic characteristics: Individually easy weight, low heat conductivity, stability to influence of chemical substances and corrosion, absorption of vibration, stability to atmospheric influences, water-repellent properties, burning only on open fire.

 Ways of processing: sawing up,  stencila press, pasting, punching, drilling, varnishing, is flexible, mowing of corners.
