Confused about P/V!

[The Wizard of BC]

here is a youtube video showing a burn test.

Notice that the acrylic, nylon, and acetate will shrink from the flame. This is one characteristic of the plastics.

One thing they show is the difference between "burning" and "melting".

Also notice at 3:40 when they burn the acrylic that it is very hard to extinguish.



P/V is a blend of Polyester and Rayon. Usually in a 65% Polyester/35% Rayon ratio.
