亚博ag真人「信誉保障」 has developed a superior performance membrane with excellent air permeability and wide chemical compatibility, by combining the technologies of gel extrusion and biaxial stretching of ultrahigh molecular weight polyethylene (UHMWPE) based on professional and rich experience in membrane fabrication. Besides, 亚博ag真人「信誉保障」 has realized the sintered Polyethylene membrane by mastering the special technology of calcination.
The ultrahigh molecular weight polyethylene (UHMWPE) microporous membrane is constructed entirely from high-density and ultra-weight polyethylene, it is a unique polymer with outstanding physical, chemical and mechanical properties. Most notable are its chemical inertness, lubricity, impact resistance and abrasion resistance. Therefore, it has better initial cleanliness and lower contaminant extrables compared with polypropylene and polysulfone.
Not requiring prewetting with solvent-based chemicals, UHMWPE membrane provides maximum chemical compatibility, longer lifetime, lower operational costs and a more consistent, reliable process. Because of higher strength versus volume ratio, UHMWPE can apply to smaller medical device profiles possible than ePTFE. And it is easy to handle and convert even at lower temperature.
Availability of graft material suitable for stent graft application is rather limited and ePTFE remains almost the only choice for small profile stent grafts. However, the results from angiographical, radiographical and histological analysis performed on all implanted stent grafts shows that UHMWPE membrane exhibits great promise as an alternative graft material for use in vascular stent graft application. In comparison to typical ePTFE, this thin and highly porous UHMWPE membrane is mechanically strong and isotropic with a breaking strength of ~20 Mpa, and hence is particularly suitable for making low profile stent grafts.
Owning to its excellent properties, the porous Polyethylene membrane can achieve high fillabiility of ultra fine particles and high resin impregnability, give it wide applications to use as a supporting material for various functional material.
