Description

Application

Additive to unsaturated polyesters, epoxides and other polymers to impart the unique properties of UHMWPE. Used in industrial parts, coatings and wear surfaces at 10-40 wt. %.

Features and Benefits

Polar surface groups assist chemical and physical bonding to matrix material. Contributes superior abrasion resistance, reduced coefficient of friction, enhanced tear strength and improved moisture resistance. Easier to process in particle form than molten UHMWPE.

Physical form

Particle surface is oxidized to contain acid and hydroxy groups.

Survival and transfer of microorganisms from kitchen sponges to surfaces of stainless steel and polyethylene.

Eliandra Mirlei Rossi et al.

Journal of infection in developing countries, 7(3), 229-234 (2013-03-16)

Contaminated sponges might lead to cross-contamination in kitchens since they can transfer microorganisms to surfaces where microorganisms can survive for hours or days and contaminate food. The main objective of this study was to evaluate the transfer and the survival

Long-term performance of ceramic and metal femoral heads on conventional polyethylene in young and active patients: a matched-pair analysis.

Morteza Meftah et al.

The Journal of bone and joint surgery. American volume, 95(13), 1193-1197 (2013-07-05)

Ceramic femoral heads produce less wear of the opposing polyethylene than do metal femoral heads in wear simulation studies. This is a matched-pair analysis of the wear of ceramic and metal femoral heads on conventional polyethylene in uncemented total hip

Alternative bearings in total knee arthroplasty: risk of early revision compared to traditional bearings: an analysis of 62,177 primary cases.

Maria C S Inacio et al.

Acta orthopaedica, 84(2), 145-152 (2013-03-15)

There is no substantial clinical evidence for the superiority of alternative bearings in total knee arthroplasty (TKA). We compared the short-term revision risk in alternative surface bearing knees (oxidized zirconium (OZ) femoral implants or highly crosslinked polyethylene (HXLPE) inserts) with
