Acid Resistant Brown FKM O Rings Metric For Aircraft Engines Seals FDA ROHS Trade Names: FKM® . . . DuPont Performance Elastomers Fluorel . . . 3M Company Technoflon . . . Solvey Solexis, USA ASTM D1418 Designation: FKM ASTM D2000/SAE Type, Class: HK ORK Compound Designation: VT Standard Color: Black Description: Combining high temperature resistance with outstanding chemical resistance, Fluorocarbon-based compounds approach the ideal for a universal O- ring material. Key Use(s): Seals for aircraft engines. Seals for automotive fuel handling systems. High temperature/low compression set applications. Wide chemical exposure situations. Hard vacuum service. Temperature Range Standard Compound: -13° to +446°F Special Compound: -40° to +446°F Hardness (Shore A): 55 to 90. Features:High fluorine grades offer higher resistance to swell in high octane and oxygenated fuel blends. This give superior performance in Ethanol/Methanol blended gasoline. Base resistant grades offer improved resistance to amine based oil protectants found in new transmission oils. Also, improved resistant to steam for higher temperature services. Low temperature bases can improve performance to -40°F. New Polymers being offered have improved chemical resistance and low temperature performance. FKM® Extreme™ ETP offers similar chemical compatibility as Kalrez™ with temperature performance with a TR(10) of -40°F and brittleness to -76°. Limitations: Fluorocarbons (FKM®s) are not recommended for exposure to ketones, amines, low molecular weight esters and ethers, nitro hydrocarbons, hot hydrofluoric or chlorosulfonic acids, or Skydrol® fluids. They are also not recommended for situations requiring good low temperature flexibility.

Summary BLUWAT F7 is a highly active liquid inorganic coagulant that offers higher effective clarification in municipal and manufacturing wastewater treatment, water purification chemicals BLUWAT F7 is a Nanotechnology coagulant and has a great deal of advantages for the biological treatment procedure. BLUWAT F7 can get a better flocs structure and enhance the sedimentation of flocs significantly, then improve MLSS and bacterial concentration throughout the biological process, so treatment performance will be enhanced considerably. It is used in the treatment of commercial and municipal wastewater treatment. Benefits Better coagulation and sedimentation of flocs Much better SVI outcome Reduction turbidity of processed water of 2nd sedimentation tank Promoting the development and reproduction of bacteria in the aeration tank. Better reduction of COD, BOD, TSS, TN, and TP by 30-60%. Avoid Scam and Bulking issues. Cutback of sludge by 30-40%. Much better sludge dewatering effectiveness. Lower treatment cost. Jar Test Procedure 1. Have the water samples from the equalization tank and 2 beakers. 2. Compare to conventional coagulant (Alum, PAC, Ferric sulphate), use 1/5 - 1/4 dose, for example, the existing coagulant is PAC, the dose is 1000ppm, so dose F7 200-250ppm in one beaker water sample. 3. Stir for 20-30 seconds, remain to inspect the sludge settling, and record the settling time. 4. At the same time, test another beaker water sample, with an existing coagulant (Alum, PAC or Ferric sulfate). 5. Compare the 2 beakers' sludge settling time, and measure the density. 6. Take the water after dealt with, and determine the COD, BOD, TSS, TN, TP, and pH worth. 7. Adjust dosage, and do more tests based upon the above actions.

TTA3150 poly [(2-ethylene epoxide) - 1 2 cyclohexane diol] 2-ethyl-2 - (hydroxymethyl) - 1,3-propylene glycol ether is a typical cycloaliphatic epoxy specialtyresins, which contains very little chloride ions and chloride salts. It has the characteristics of high transparency, high heat resistance, high Tg, excellent weather resistance, and excellent electrical properties (arc resistance and electric trace resistance). Its epoxy group at the end has similar reactivity with the epoxy group of polyether polyol glycidyl amine epoxy resin and can be cured with curing agents such as anhydride, phenol, amine, and cationic curing agent. It is widely used in composite materials, electrical insulation materials, electronic adhesives, powder coatings, and other fields. Specifications of Tetra TTA3150 (Cas 244772 00 7) Grade TTA3150 Product name Poly[2-oxiranyl)-1,2-cyclohexane diol]-2-ethyl-2- (hydroxymethyl)-1,3- propan , ediol ether CAS No. 244772-00-7 Content（%） 95.0 min Epoxy equivalent (g / eq) 170～200 Chroma 50 APHA max Softening Point (℃) 70～90 High Heat Resistance The curing of TTA3150 with methyl-hexahydro phthalic anhydride has excellent transparency and high heat resistance temperature; the curing with methyl- tetrahydro phthalic anhydride has slightly lower Tg and yellow color, and the curing with methylnadic anhydride has better heat resistance than that of the above two anhydrides. It shall be noted that the color after curing is brown and translucent. Special attention: TGA data show that the TTA3150 and MHHPA cured product has the highest thermal decomposition temperature, and the TTA3150 and MNA cured product has the highest Tg, but the lowest thermal decomposition temperature.
