| Natural Cotton (U) For oils, water, paints, organic solvents, alcohols, petroleum. For use to 300ºF. FDA Bleached Cotton (C) Bleached to meet FDA standards for distilled water, beverages, vegetable oils, petroleum, fatty acid, and alcohols. For use to 300ºF. Poor microorganism resistance. Polypropylene (P) — “Standard Polypropylene” Recommended for concentrated acids and alkalies, strong oxidizing agents, corrosive fluids and gases. FDA and non-FDA available—consult factory. Easily incinerated to trace of ash. Excellent microorganism resistance. For use to 200ºF. FDA Polypropylene (PD) — “Utility Grade Polypropylene” Same applications as standard polypropylene but less consistency in appearance due to discoloration, nicknamed “rainbow.” For use to 200ºF. Primary used in waste water treatment and non-critical, high volume applications. Fibrillated Polypropylene (F) — “Electronic Grade” Non-migrated slit film polypropylene recommended for use in ultra-pure liquids, electronics, and plating where non-leaching is critical. No extractables or sizing agents present. Chemical resistance equal to standard polypropylene. Low moisture absorption and outstanding abrasion resistance. Lowest static propensity of any man-made fiber. High dry or wet strength. Rayon (R) — “Viscose Rayon” Fluid compatibility simular to bleached cotton, but has no more coarse fiber and is less absorbent than cotton. Swells in aqueous solutions. For use to 300ºF. Polyester (K) Chemical resistance similar to polypropylene, with high temperature resistance. For use to 350ºF. Nylon (N) For special process applications, concentrated alkalies, and hydrocarbons. Excellent microorganism resistance. For use to 300ºF. Acrylic (O) — “Modacrylic” For strong acids, concentrated alkalies, and oxidizing agents. For use to 200ºF. Not recommended for organic solvents. Baked Fiberglass (GH) — “Heat Cleaned Glass Fiber” Trace oil removed by heat cleaning to yield virgin glass fiber. Recommended for high corrosion applications. For use to 750ºF during manufacturing process. |
