Composite materials (or composites for short) are engineered materials made from two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct on a macroscopic level within the finished structure.
1. Why do you choose to pronounce this word differently than engineers, aerospace, marine, etc?
2. My understanding is that BPA can either be chemically combined in the plastic or incorporated separately as a plasticizer. My understanding is that a few of the dental products have it in as a stand alone component while the majority have it chemically combined. The UCLA organic chemistry professor said it is a risk only in those products where it is not chemically combined.

The variation in pronunciation of the word “composite” seems to be regional. No deeper meaning.
Though I’ve lived in California for years, I grew up in New England, and there are still some words that I say differently… Not quite “Pahk the cah in Hahvahd Yahd,” but I do put mail in an “ahnvelope.”
