VMQ has a good heat resistance as much as 232° C in hot air and as much as one hundred° C in water. NBR hollow O-rings can be utilized in static purposes where low closing drive is required. Nitrile has a great basic oil/gasoline resistance, but poor ozone and weathering resistance.

American Seal and Packing encourages you to provide us a call at to ensure you’re receiving exactly what you want for your software. Kalrez® has a “good” score for put on, compression set, and permeation resistance. Fluorosilicone has a “reasonable” ranking for both compression set and brief-term resilience, and a “poor” score for put on and permeation resistance. Silicone has an “glorious” score for both compression set and permeation resistance, and a “poor” score for put on and short-term resilience.

Silicone has a great heat resistance, good chilly flexibility, and good ozone and climate resistance in addition to good insulating and physiologically neutral properties. Various specs will favor one material over another.

Seal & Design has many compounds out there that meet FDA, USP Class VI, three-A or NSF sixty one specifications. Square O-Rings, or Kantseals®, are an alternate for O-rings in axial static purposes. Square rings have excessive sealing capability and shape stability. Oil seals, radial shaft seals or Simmerrings® have been designed for sealing shafts and spindles. Silicone hole O-rings can be used in static functions the place low closing pressure is required.

Simriz® White Perfluoroelastomer O-Rings are particularly developed to be an economical, excessive-performance compound for semiconductor applications. Simriz® 486 exhibits excellent plasma resistance and low particulation in a variety of plasma environments. Pharmaceutical o-rings are utilized in pharmaceutical, biotec, meals & beverage purposes.

We provide normal and engineered pumps, heat exchangers, mixers, and supply consultative companies for these and most different process gear. We’re particularly robust in mechanical seals, seal repair, design and modifications. Our ANSI pumps and parts program rolling out in late 2013 will amaze you! Silicone covers a large group of supplies during which vinyl-methyl-silicone is often the central ingredient. Silicone elastomers as a gaggle have relatively low tensile power, poor tear and put on resistance.

Trelleborg Sealing Solutions is a worldwide producer of hydraulic seals, rotary seals, pneumatic seals, Teflon® seals and different precision seals. We serve aerospace, automotive, authorities companies, medical, oil, gasoline, sanitary and plenty of different industries.
