The concrete and brick used to create this handsome patio seating area are low-maintenance materials that resist the effects of wind, water, and temperature changes. The washed-aggregate surface of the concrete doesn't need sealing.
VitonÂ® Sponge plays a particularly vital role in cases where soft flouroelastomers are desirable. hardness limit for solid VitonÂ® is 55 durometer. the heat and fluid resistance of solid VitonÂ® is necessary. high resistance to ozone attack, and low moisture absorption. 24â x 48â in 1/8â, 1/4â and 3/8â thicknesses.
Are there any differences between black, brown or green viton flat seals. I have an application (Steam @ 140Â°C pressure 2.3bar-also vacuum at 100mbar) where I have validated the use of a 70 shore hardness Viton seals on some Solenoid valves. The seals were black in colour.iton or more general Fluorocarbon rubber (FKM or FPM)includes different materials. They can have different fluorine content (between 66 and 71 % fluorine) and hence very different swelling behaviour in solvents as e.g fuels, aromatics, methanol ...
