Further Adavances In Use of Polymer Process Aids to Reduce Material Cost

High filler loading of rubber to date has been a challenge in respect of viscosity control, heat build up and related degrading influences and dispersive quality becoming critical etc., Process aids from synthetic and from natural sources are being promoted in the field.  However high cost remains an issue.  Leveraging the ability to load high filler levels in compounds with polymer process aids, formulations were developed for quality rubber products, in particular molded goods, without compromise in quality. Various formulations were tested and compared with conventional recipes excluding the polymer process aids. The results show the prospect for reducing costs of most products, especially in a high labor cost country like the United States, to levels that these products would become highly competitive both in domestic and international markets. This paper will illustrate the findings with recommended recipes.
