Material Notes:
QUINN XT sheets have good optical properties and a brilliant surface. QUINN XT sheets offer excellent transparency, good mechanical properties, are UV resistant, have very good weathering and ageing resistance and remain color constant for years. High impact grades, QUINN XT610, XT620, XT630, have outstanding mechanical properties and excellent impact strength. Both QUINN XT sheets and all high impact grades can be used in contact with foodstuffs, as they meet all current European food control legislation. QUINN XT sheets and the high impact grades do not contain any toxic materials or heavy metals, which may cause environmental damage or health risks. It is insoluble in water, and not subject to hazardous materials identification. QUINN XT sheets and the high impact grades are easy to recycle.Construction Components Light domes Partition walls Door Glazing Roofing Skylights for caravans Lighting Lighting control lensesDomestic light fittings Engineering ComponentsMachine housings, machine safety covers Advertising and SignageMolded lettersStore displaysShop fittingsIlluminated graphics panels Other ApplicationsContainersLettering TemplatesSolariumsSound Barrier WallsQuinn Manufacturing Group rebranded its Plastics Division as Polycasa in 2013.
