As a motorcyclist of long standing, I would have to say that this
claim is nonsense.  Many, many different plastics are used in mc
helmets, with varying degrees of flexibility, strength, shatter
resistance, hysteresis, and what have you.  If they meant lexan, or
one of the engineering thermosetting compounds, then my reaction is
"Ho Hum".  That's what your description sounds like.  They are used in
bottom-of-the-line stuff.  Middle-of-the-line is usually
fibreglass/expoxy; top-of-the-line is generally kevlar/expoxy, and can
be very expensive (I paid $440 for my kevlar/epoxy full coverage hat).
