DAP: Cosmic Plastics D33/6120 vs. Sumitomo Bakelite 52-01
As soon as you lay eyes on the two data sheets for these materials, Cosmic D33/6120 and Sumitomo Bakelite 52-01, there are some pretty clear differences in mechanical, thermal, electrical, and physical properties. There are three distinct hypotheses relating to why the plastics are so distinctly different from one another: 1. unique composition; 2. different molding procedure; and 3. separate molding parameters A closer look into each of these hypotheses is necessary in explaining why the Sumitomo Bakelite and Cosmic DAPs are so different from one another.
