Arla MAKROCLEAR™ SQ PC Sheet
Categories: Polymer; Thermoplastic; Polycarbonate (PC); Polycarbonate, Extruded

Material Notes: MAKROCLEAR™ SQ is Selected Quality transparent polycarbonate sheet is produced with advanced extrusion technology with outstanding optical and surface quality. The product is produced by a production team experienced in producing mono, co and tri-extrusion. The product is virtually unbreakable with extremely high impact resistance and offers high temperature performance too. The product provides designers, specifiers and architects with possibilities to use the sheets in applications where high optical quality is required replacing glass and other transparent plastics. The consistent high quality demands from the market helps to improve optical quality, machining, screen printability and thermoformability. EXCELLENT FIRE PERFORMANCE complying requirements to EN 13501-1 (EUROPEAN BUILDING STD). In case of fire, the sheet will melt and allow venting where heat and smoke will be let out and therefore reduce the growth of fire by flame spread.

Benefits: High optical quality and outstanding clarity; Half the weight of glass; More than 10 times the impact strength of high impact PMMA; Good fire classification

Application: The selective quality properties of MAKROCLEAR™ SQ makes it a perfect solution for glazing, machine protection, safety glazing, ice hockey rinks, visors, optical distortion free parts, vandal protection, sound walls / sound barriers etc.
