Starting at 1-14 thick it can be used as one huge sheet or cut to a variety of s
ize options. Polystone G Pipe Grade is especially useful as a MegaSheet for large flanges and manholes eliminating the need for welding and concerns about seams breaking. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 21 pcs. 32 x 32 from one 8 x 20 MegaSheet vs With full cutting capabilities in-house to handle this huge sheet we can help you achieve yields that are significantly better than those of standard sheet sizes.

Acetone Hydrogen peroxide 30 Sawing Acrylonitrile Hydrogen sulphide Allyl alcohol 96 96 Lactic acid Aluminum chloride A A Magnesium chloride A A Ammonia A A Mercury Fast-running circular and band saws are suitable. Smooth surfaces can be achieved when the teeth are lightly set. Saw blades with teeth more than 58 apart are suggested. Especially with PP fast chip removal is essential to prevent melting. Ammonium chloride A A Methanol Milling Aniline Methyl ethyl ketone Benzaldehyde Methylene chloride Benzene Mineral oil Benzyl alcohol Motor oil Fairly high feed rates and revolutions work best with attention to reduce heat generation. Suggested 9000-12000 rpm with a feed rate of 250-300 inches per minute. Bleach Chlorine Nitric acid 25 25 Welding Boric acid A A Nitrobenzene Butanol Oleic acid Butyl acetate Ozone Calcium chloride Perchloric acid Quality welds are achieved with the appropriate temperature setting and air pressure. The welding r
