UHMWPE Biomaterials Handbook, Third Edition, describes the science, development, properties, and application of ultra-high molecular weight polyethylene (UHMWPE) used in artificial is now the material of choice for joint replacements, and is increasingly being used in fibers for sutures. UHMWPE Biomaterials Handbook describes the science, development, properties and application of of ultra-high molecular weight polyethylene (UHMWPE) used in artificial joints. This material is currently used in million patients around the world every year for use in the hip, knee, upper extremities, and spine. Introduction. For over four decades, ultra high molecular weight polyethylene (UHMWPE) has been used as one-half of the metal- or ceramic-on-plastic bearing couple in total joint replacement (TJR) components due to its toughness, durability, and biological inertness ().Though there are metal-on-metal and ceramic-on-ceramic bearing couples, the majority of joint replacement Cited by: Ultra High Molecular Weight (UHMWPE) Polyethylene materials have unique properties like high impact resistance, durability, high thermal conductivity and low dielectric constant. The Seeker makes an UHMWPE into a tape form, available as tape itself or as woven tape fabric.

The high molecular weight, between 2 and 6 million g/mol, results in a high resistance to mechanical stresses in comparison with other types of polyethylene (HDPE, LDPE, and others). Macro- and micropores as the defects of UHMWPE internal structure decrease its mechanical properties and increase failure rate by: 9. Abstract: Ultra-high molecular weight polyethylene (UHMWPE) has been the most commonly used bearing material in total joint arthroplasty. Wear and oxidation fatigue resistance of UHMWPE are regarded as two important mechanical properties to extend the longevity of knee prostheses. Though accelerated in vitro protocols have been developed toFile Size: KB. The wear properties of biomaterials have been demonstrated to have a high importance within orthopedic bearing surfaces. This study performed a comparison of the wear between the two main grades of Ultra High Molecular Weight Polyethylene types GUR and GUR articulating against Cobalt Chromium. Such a high capacity wear comparison has not been Cited by: 6.
Ultra-high molecular weight polyethylene degrades during storage in air following gamma sterilization, but the extent of in vivo degradation remains unclear.

Partially degraded high-density polyethylene (HDPE) was collected from plastic waste dump yard for biodegradation using fungi. Of various fungi screened, strain MF12 was found efficient in degrading HDPE by weight loss and Fourier transform infrared (FT-IR) spectrophotometric analysis. Strain MF12 was selected as efficient HDPE degraders for Cited by:
