Key factors contributing to the fine cell structure are the particle size of the blowing agent, the dispersing capability of the molding machine, the decomposition rate of the foaming agent, the melt viscosity and the molecular structure of the thermoplastic resin itself. ADDITION LEVELS OF FOAMING AGENTS Both the foaming agent and the thermoplastic resins are metered into the injection molding machine. When processing Hydrocerol concentrates in powder form it is advantageous to add small amounts (0.1%) of adhesion promoters to avoid separation from the resin.

importing environmental copper into the cells) as well as interfering with iron metabolism pathways.[24,25] Herein, an assortment of both rigid and flexible resins/ compounds will be evaluated for susceptibility to determine whether particular resin chemistries or compounds are inherently vulnerable to microbial growth and subsequent degradation or other deleterious effects. These various elastomers contain a propriety combina- tion of base resins, processing aids, fillers, stabilization packages, and other additives. They represent a wide variety of resins and/or resin mixtures, processing aids, and stabilization packages used in current TPE tech- nologies.
