Expansion Seal "CEFIL'AIR"
Can be produced from palm-sized to several dozen meters! Designed according to specifications and requests.
"CEFIL'AIR" is an expansion seal for extruded products that expand and contract due to air pressure and other factors. It can accommodate vacuum levels from 0.133 Pa to approximately 10 barG with various combinations of elastomers and cross-sectional shapes and profiles. Performance depends on the contact surfaces and installation conditions. Materials available include silicone, SBR, EPDM, FKM, and others, with silicone rubber capable of withstanding temperatures from -50°C to +250°C. Certification for FDA and USP Pharma Class VI is also possible. 【Features】 ■ Extruded products ■ Expand and contract due to air pressure and other factors, accommodating vacuum levels from 0.133 Pa to approximately 10 barG with various combinations of elastomers and cross-sectional shapes and profiles ■ Can be manufactured in various shapes from palm-sized to several dozen meters ■ Designed based on specifications and requests after consultation ■ Materials (silicone, SBR, EPDM, FKM, etc.) with silicone rubber capable of withstanding temperatures from -50°C to +250°C, and certification for FDA and USP Pharma Class VI is also available *For more details, please download the PDF or feel free to contact us.
