Daniel Pearce, president of Technical Compounding Services, Inc., addressed converters' responsesto pricing pressures and decreasing development times, often through consolidation andinterpolymer substitution. Advances in olefin polymers were said by Kurt Swagger, R&D director,Polyolefins & Elastomers R&D, Dow Plastics, to be driven by concerns about recyclability, sourcereduction, demands for lower-cost polymers, and decreasing development times and life cycles.Swagger stressed that a key driving force is the manipulation of molecular architecture--orrearranging simple monomers to achieve higher properties without the expense of new polymerchemistries. Dow's new Insite technology is one example of such manipulative techniques.

The two worst problems in molding fiber-reinforced plastics, according to John Theberge, MaterialsDevelopment Corp., are weldline integrity and anisotropic moldings. One solution described byTheberge is multiple-live-feed injection molding. Feed is split and packing pressure is applied by twopistons that can oscillate either 0 |degrees~ or 180 |degrees~ out of phase. The oscillation of thematerial removes any weldlines and orientation. In double-live-feed molding, with proper phasing ofthe four pistons, 90 |degrees~ laminates have been fabricated in situ. Another method, push-pullinjection molding, involving alternating feed from two injection units, was developed by Klockner,and, Theberge said, is still only available in Germany.

As expected, the issue of recycling quickly took center stage and held it for the duration of theforum. Moderator Bill Nigut, a political reporter from WSB-TV, Channel 2, Atlanta, valiantly stroveto get to the core of the matter as the sometimes impassioned panelists and audience members viedto make their points, for or against government, the public, or the need for more regulation or morelaissezfaire. The conviction resulting from the extensive interplay of ideas is that there is aconsiderable distance to go before any real consensus can be reached, and that essentially what wasachieved was to replay previous environmental Super Sessions in a later time frame, albeit withdifferent, more dramatic staging.

A Corporate Environmental Program

At ANTEC '93, however, one word--"infrastructure"--was most often heard in refrain, and withsomewhat more focus than at previous ANTECs. The lack of a viable infrastructure, the need for it,and the role of partnerships between government and industry to foster it were extensivelydiscussed. In the contest of ideas at the '93 Super Session, the need for practical planning to meetinfrastructure requirements seemed to catch up fast with consumer education in the quest to

advance recycling. While the unthinking tosser of a plastic cup got a sound drubbing as one of themajor culprits, panelists and audience moved closer to the concept that--where effective growth ofrecycling is concerned--money and organization, and building of markets for recycled products, willbe what will ultimately carry the day.

The key torestoring profitability and avoiding extensive downsizing, Gambrell said, is rapid growth "bydeveloping new applications, and at the same time, . . . extract(ing) maximum value for thecontributions we make to new and better products." Maximum value cannot be obtained throughinterpolymer competition, he maintained, but by challenging traditional materials, which still have95% of the materials market.

Applications for gas-assisted injection molding, said Andrew J. Poslinski of GE Corporate R&D, aredeveloping for thick parts such as hollow beams for handles and frames, and for hollow ribs on thinparts such as panels and chassis. Part performance depends on the skin thickness, which isdetermined by the extent of gas penetration. The viscosity and shear thinning characteristics of thematerial affect the gas penetration, and because the gas follows the path of least resistance inprocessing, special software is needed to help design systems with balanced flow.

Donald L. Hunston of the National Institute of Standards and Technology said that the challenge inthe processing of thermoset composites is to convert high-performance composites for the aerospaceindustry into cost-performance composites for industrial applications. He contrasted the AutomobileComposites Consortium's goal of five minutes to manufacture the front of a Ford Escort with the oneto four days typically required to manufacture an aerospace part, and because fabrication accountsfor 72% of the cost of the latter, traditional processing methods are not being used optimally.

Hanser Gardner Publications offered information on its publications, including reference books andtexts on plastics engineering, processing (extrusion, injection molding, and blow molding), polymerscience, and materials science.

SPE's New Technology Committee presented a lively, comprehensive update on processing--its effecton part performance, recent developments, and challenges--at the second New Technology Forum.Dr. Vijay K. Stokes, of GE Corporate R&D, stressed the importance of including the effects ofprocessing when predicting the structural performance of a part. Key factors are the type ofmaterial, amorphous or semicrystalline and neat or filled or reinforced; and whether or not the part

geometry depends on the processing. Only neat amorphous systems with their geometry dependenton the processing can be analyzed by structural mechanics, i.e., conventional finite-element analysisbased on ASTM data, Stokes said. All other systems require process mechanics and micromechanicsto determine morphology and properties before structural mechanics can be applied.
