  • Medical Device Link . Performance Properties of Metallocene Polyethylene, EVA, and Flexible PVC Films
    . Among the materials that have been introduced as alternatives to flexible PVC are films made with metallocene polyethylene (mPE) or ethylene-vinyl acetate (EVA) resins. It has been demonstrated in a previous study that mPE films offer a number of attractive performance attributes, including superior
  • Medical Device Link .
    desire in the medical industry for alternative plastic films that could be sealed with HF energy. Thermoplastic polyurethane (TPU) and ethylene-vinyl acetate (EVA) resins have increasingly been used to produce films that could be readily HF welded. Collection bag used to develop HF-weldable polyolefin
  • Plastics Consultancy Network - Mixing and compounding masterbatches
    to be one of the following: low density polyethylene, polypropylene, polystyrene, EVA , low molecular weight wax, an alkyd resin, or a more polymer specific material.
  • Medical Device Link .
    for the standard packaging tests often leads to a product release before the tests are completed. The package chosen for testing was that of the Insyte N catheter (Becton Dickinson; Sandy, UT), comprising an EVA/K-resin/EVA bottom web and coated Tyvek lid. The net result of these problems in package
  • Compounding Cable Covering in a Rotary Mixer
    of thermoplastic resins, including LDPE, LLDPE, EVA, PP, CPE, and Silicone, which we mix with peroxides to produce thermosetting (or crosslinkable) compounds," he explains. The insulating compounds are crosslinked to allow the cables produced with them to operate at higher temperatures than thermoplastic
  • Plastics Processing Applications: Continuous Hot Melt Production
    of manufacturing processes, including bookbinding, product assembly, and box and carton heat sealing. There are a number of hot melt adhesives in use, with the most common being those used for hot melt pressure sensitive adhesive applications: Ethylene vinyl acetate (EVA) copolymers, compatible with paraffin
