Summary of Expertise: Listed with other top experts in: 
Expert has worked with engineering resins, commodity resins, and thermoset resins. He has first-hand expert knowledge of acetal resins such as Delrin and Celcon and of thermoplastic polyester resins such as Valox, Rynite, PBT, and PET. Expert's knowledge extends to nylons, including cast nylon parts up to 1000 pounds in size from caprolactam monomer, and aromatic based polymers such as Kevlar, Nomex, Xydar, LCP (liquid crystal polymers), polysulfone, PPS, and PEEK. He has experience with SMA, acrylics such as lucite and plexiglass, and polyolefins such as PE, PP, LDPE, LLDPE, HDPE, and UHMWPE. He has worked with polystyrene based materials such as PS, ABS, SAN, and Noryl, as well as vinyls (PVCs). He has had experience with thermosets such as phenolics, urea-based, and epoxies. In addition, he has expert level experience and knowledge of fluoropolymers and silicones. These fluoropolymers include Teflon, Fluon, Tefzel, Kynar, Kel-F, PTFE, FEP, PVF, AND PVDF; silicones include polysiloxanes and polysilazanes.

Expert has worked with cellulose and modified cellulose polymers such as paper, CA, HEC, and CMC. He has worked with thermoplastic elastomers such as TPU, TPO, and TPR and with elastomers such as natural rubber, EPR, EPDM, SBR, nitrile, polyurethanes, and silicone elastomers. He also has had experience with many fluorine based elastomers, fluorosilicone elastomers, and water soluble polyethers such as PEO, PPO, Polyox, and Carbowax. He has worked with other water soluble and dispersible polymers such as polyvinyl alcohol, polyvinyl acetate, as well as polyamines such as TETA, TEPA, polyethyleneimine, and related ethanolamines. He has done some recent work with preceramic polymers such as polysilizanes and inorganic polymers (high performance ceramics) such as silicon nitride, carbide, oxynitride, zirconia, and alumina.

Expert's expertise includes grafting acrylics and vinyls onto PE and PP. This has involved grafting maleic anhydride or trialkoxyvinylsilane while minimizing cross linking of PE and reducing MW loss on PP. He has worked with rubber grafted impact modified nylons. He is familiar with creating alloys of nylons and fluoropolymers by reactive processing. His expertise also includes rigid and flexible, chemical and physical, and extruded and injection molded foams.

Expert has expertise in fiber and mineral modified polymers. The fibers include those of glass, carbon, and sisal while the minerals include talc, mica, silica, abrasives. He is also familiar with grinding wheels and glass-fiber-reinforced fast-crystallizing PET.

Expert is an expert on all common and many uncommon polymer modifiers and additives. He has worked with fillers having negative coefficients of thermal expansion, thermal stabilizers, antioxidant systems, durable polymers, hydrolytic stability, and impact modified and toughened resins. Expert has also worked with halogen and non-halogen flame retardants.

Expert's experience has included compounding extrusion, shape extrusion, extrusion blow molding, and novel extruder designs. His expertise includes injection molding, foams, injection blow molding, and ram extrusion.

Expert has had experience with heat shrinkable films and heat-shrinkable fluoropolymers. He has also worked with preceramic polymers, water-soluble polymers, highly filled systems, novel alloys and blends, UV-stabilized systems, polarizer films, and tie layer polymers.
