In this article, nanocomposites based on polypropylene containing montmorillonite, modified with two different intercalants (primary and quaternary amine), at three different coverage levels have been investigated. The specimens were prepared in a mini-extruder machine with a counter-rotating configuration. The effectiveness of intercalant type and clay coverage level on the dispersion was analyzed by different means, including Xray diffraction analysis, field emission gun scanning electron microscopy, transmission electron microscopy, and differential scanning calorimetry. The flexural p

    • Although a wide range of new additives were discussed at the SPE Polyolefins 2005 conference held in Houston earlier this year, one theme stood out strongly. This was the emergence of novel coupling agents to satisfy the growing interest in improved processing and performance for polyolefin natural-fiber composites and mineral-filled ......
  • New technology for enhancing wood-plastic composites.
    • INDUSTRY BACKGROUND Wood-plastic composites (WPC) are the combination of wood fibers, most commonly wood flour waste, and a thermoplastic such as high density polyethylene (HDPE), polypropylene (PP), or PVC. The polymer content is generally 40-50% by weight. WPCs are extruded into profile shapes via continuous extrusion for the building ......

    • Abstract This study examined the effects of a compatibilizer on the wettability of birch plywood and polyolefins. The compatabilizer was a low molecular weight emulsion type maleated polypropylene (MAPP), Epolene E-43. The polyolefins investigated included low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), and polypropylene (PP). For E-43 treated wood surfaces, ......
