Comparison of Process Aid Ingredients in a Water-Resistant Neoprene.

摘要

Neoprene compound 5109 is used extensively by the NRL-USRD and industrial activities for underwater acoustical devices. It contains a proprietary process aid (Technical Processing, Inc. TE-70). Recently, TE-70 has become very difficult for the NRL-USRD to obtain. This report outlines work by the NRL-USRD to eliminate use of proprietary materials in the formulation of compound 5109. Two approaches are presented; (1) Eliminate the use of any process aid; (2) Reformulate compound 5109 using alternative process aids. This report also describes the processability, physical characteristics, and bondability of several alternative formulations for Neoprene 5109.
