3Businesses in Texas needing chemically resistant, low friction static and dynamic sealing solutions can procure these from Advanced EMC Technologies. They produce high grade FDA compliant PTFE seals that can withstand extreme temperature and pressure.

An executive with the company threw more light on the feature saying, “As the system pressure raises enough to take over from the spring and engage the shaft an ultra-efficient seal is created. The spring of the spring energized seal provides permanent resilience to the seal jacket compensating for jacket eccentricity, wear and hardware misalignment.”

Other salient features of the seals are fluid handling, high PV grades, unlimited shelf life, controlled friction/load and FDA/USDA compliance. The seals are efficient in dry running or lubricated, cryogenic and HPLC applications. They can effectively be used across sectors like medical and defense, medical, biomedical, food service, oil & seismic transportation and pharmaceutical. Polymer seal jacket are made of varied materials like virgin PTFE, carbon/graphite PTFE, moly/filled PTFE, glass/moly PTFE, polyimide/filled, UH/polymer PE, 60% bronze/filled PTFE and PCTFE/ KEL F.

FDA approved Virgin PTFE are known for low friction and light duty service. The executive elaborated, “1000 Fluorolon Virgin PTFE seals are excellent for cryogenic and low molecular weight gas service. It can withstand temperature range of -320 to 450F. Extrusion resistance and friction rating is lowest. Carbon/Graphite PTFE 1034 Fluorolon jacket seats, on the other hand offer excellent resistance to heat and wear. It is recommended for dry or semi-dry apps. It can stand temperature ranges of -320 to 500F. Extrusion resistance is moderate and friction rating is low.”

1017 Fluorolon Moly/Filled PTFE seals are excellent in dry gas with better wear resistance. Temperature range is -320 to 525. Extrusion resistance is very high and Friction rating is low. 1050 Fluorolon Glass/Moly PTFE seals offer superlative wear and heat resistance. These are abrasive in rotary service against soft metals and effective in high pressure applications. It is meant for temperature ranges of -250 to 550F, have very high extrusion resistance and moderate friction rating.
