DUSSELDORF, GERMANY - Exxon Chemical Co. is developing injection molding grades of resins made with metallocene catalyst technology. Peter Bailey, a development engineer for Exxon Chemical Europe, said Exxon is developing the products in Sarnia, Ontario. He did not say when they may reach the market.
Bailey was one of two speakers from Exxon at Metallocenes '96 in Dusseldorf.
While resin processors said they remain skeptical about the benefits of resins made with metallocene technologies, Bailey and Jo Aendekerk, a researcher at Exxon Chemical Europe Inc.'s Machelen, Belgium, Chemical Technology Center, said their customers are reporting a variety of advantages gained from using its materials.
Bailey provided examples of applications for Exxon's metallocene linear low density polyethylene resins in blown film and other extrusion processes, while Aendekerk addressed applications of Exxon's plastomer products. Aendekerk's examples included heat-seal, multilayer film, high-performance packaging for food and polypropylene resin modification applications for plastomers.
While the types of extrusion applications they described have been common goals for metallocene resins, injection molding applications were not pursued previously. Those extrusion applications use much larger quantities of resins than injection molding applications would, so Exxon and its competitors set their sights on them first.
Exxon's development of an injection molding grade would appear to broaden the scope of applications for resins made with metallocene technologies.
