Polystyrene:
Soft flexible plastic that allows light to illuminate. Will melt
at fairly low temperature. Thin construction. Brittle yet
flexible. Made in every color in the rainbow. Can also be mixed
with other colors to create swirls or marbling.
Tenite: A hard low temperature plastic generally made in Ivory or other light colors. Thin construction. Not very flexible and breaks easily. Low temperature for melting. Known to droop such as its use as attached radio grilles in the 30s and 40s that have a melted or warped look. Lucite: Clear, soft and flexible. Can be cut, twisted in heat, bent, etched and made very thick. Can also be tinted various colors.
Acrylics: Clear or opaque but allows light to traverse thru. Stiff, brittle but durable. Very high use even today. Little use in radios other then dials or dial scales. Has a low melting point. Made in many colors.
