Product Details

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
