Greene Tweed Receives Patent for Rapid Gas Decompression-Resistant Fluoroelastomers and Molded Articles
24.10.2018 00:00:00 EEST | Business Wire | Press release
The U.S. Patent Office has awarded Greene Tweed Patent Number 10,011,690 for Rapid Gas Decompression-Resistant Fluoroelastomer Compositions and Molded Articles. The innovative elastomer technology was developed by a team that included inventor Ron Campbell, PhD, Principal Scientist and Technology Leader for Elastomers in Greene Tweed’s Advanced Technology Group, to provide a competitive advantage in the Energy market and expand technology protected under a previous patent.
Rapid gas decompression (RGD) often occurs when high-pressure gas molecules migrate into an elastomer at a compressed state. When the pressure surrounding the elastomer is suddenly released, the compressed gas inside the elastomer tries to expand and exit the elastomer, thus causing RGD (also known as explosive decompression). Most elastomers experience severe blistering or cracking when the force of these expanding gases overcome the strength of the surrounding material; however, materials engineered to withstand RGD are more likely to maintain their integrity in the application.
RGD-resistant elastomers are widely used as seals and gaskets in compressors and down-hole applications where seals could encounter long soak times in high-pressure gases. Leaks and excessive cracking can lead to unnecessary downtime associated with unplanned maintenance, causing health, safety, and environmental issues and significant lost production time.
RGD-resistant elastomeric seals are generally optimized for seal designs with cross-sectional diameters less than 5.44 millimeters. This patent protects Greene Tweed’s technology for compounding and curing fluorocarbon elastomer seals with cross-sections that approach or exceed 10 millimeters, enabling us to offer superior reliability in larger seal cross-sections exposed to RGD environments.
The International Standards Organization’s ISO 23936-2:2011(E) and NORSOK M-710 serve as Oil & Gas industry benchmarks for RGD resistance. ISO and NORSOK also evaluate seal performance in an RGD environment.
Greene Tweed’s NORSOK M-710 and ISO 23936-2:2011 qualified materials include Chemraz® 526, 678, and 566, and Fusion™ FKM 938 and 944.

Vertex Presents New Data on ALYFTREK ® at European Cystic Fibrosis Conference5.6.2026 19:00:00 EEST | Press release
Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced data demonstrating the potentially transformative impact of treating cystic fibrosis (CF) with ALYFTREK ® (vanzacaftor/tezacaftor/deutivacaftor) in children ages 2 to 5, as well as data from 96-week interim analyses of two open-label extension studies of ALYFTREK in children 6 to 11 years and people 12 years and older demonstrating the long-term safety and efficacy profile of the medicine. The data, presented at the European Cystic Fibrosis Conference, show children ages 2 to 5 with vanzacaftor/tezacaftor/deutivacaftor-responsive genotypes including those who are homozygous for the F508del mutation (F/F) and those who have F508del/minimal function mutations (F/MF)on ALYFTREK had further improvement in CFTR function from a TRIKAFTA ® baseline as measured by sweat chloride (SwCl), with 65% having achieved SwCl <30 mmol/L after treatment with ALYFTREK. Vertex also presented Phase 3 data of children ages 1 to <2 with TRIKAF
