GUJPOL-S is the trade name of Acrylic sheets manufactured by GSFC. GUJPOL-S sheets are manufactured from virgin MMA by cell casting process the best optical properties among all transparent plastics. GUJPOL-S has an excellent resistance to the effect of long exposure to sunlight, heat and weather Applications . Light fitting and fixtures. Street light covers. Sanitary articles. Sigh-boards and novelties. Helicopter canopies and other defence items The outstanding features of Gujpol-S sheets are . Light in weight; It has only half the weight of glass.. Weather resistance; Longer period of resistance to sunlight and other weather conditions.. Light absorption; Minimum in clear transparent sheets.. Wide range; Transparent, translucent and opaque colours.. High surface gloss.. Easy formability and machinability.. Low thermal conductivity; Almost equivalent to phenolics and only one sixth that of glass.. Resistance to a wide range of chemicals insoluble in most inorganic chemicals but dissolves in ketones, esters, aromatic hydro carbons, chlorinated solvent etc. Packing =GUJPOL-S well masked with craft paper on both side and packed in standard packing in thick corrugated paper and bundled with straps
