Patent number: 10400926Abstract: Wearable rubber parts for fluid handling systems include a four layer structure, wherein the inner most layer of the four layer structure is a polyurethane layer. The polyurethane can be millable polyurethane. The polyurethane used in the inner most layer can be produced by reacting diisolcyanate with a polyester and/or polyether polyols and a chain extender. The wearable rubber part can be an expansion joint, a pinch valve, or a hose.Type: GrantFiled: July 3, 2018Date of Patent: September 3, 2019Assignee: GARLOCK SEALING TECHNOLOGIES, LLCInventors: Louis J. Mattina, Stephen Joseph Cramb, Brandon T. Phillips, Benjamin James Whipple, Sherwin A. Damdar

Patent number: 9732855Abstract: An extreme temperature gasket material capable of withstanding temperatures in excess of 850° F. is provided. The extreme temperature gasket generally includes an inorganic filler, an inorganic fiber, and an organic binder. In some embodiments, the inorganic filler is from 75 to 90 wt % of the gasket material and can include submicron-sized talc particles. The inorganic fiber can be from 5 to 20 wt % of the gasket material and can include silicic acid fiber. The binder can be a latex emulsion and can be present in the gasket material in the range of from 1 to 5 wt % of the gasket material. The gasket material also can include additives, such as flocculant and defoamer. In some embodiments, the amount of organic material present in the gasket material is limited to less than 5 wt % of the gasket material.Type: GrantFiled: October 4, 2011Date of Patent: August 15, 2017Assignee: GARLOCK SEALING TECHNOLOGIES, LLCInventors: Sherwin Damdar, James Drago, Paul Jude Nichols
