a breakdown of some of the important properties of plastic and acrylic.
A clear material with excellent
optical properties that make it almost better than glass. Acrylic is hard
and relatively scratch resistant.
A hard opaque material that
has high heat resistance and will not melt, making it suitable for dinnerware.
A material that looks like
acrylic, but is softer and scratches more easily. Although it has moderate
chemical resistance, it can cloud or discolor as a result of prolonged exposure
to citric acid.
A material with excellent
chemical and heat resistance that is difficult to crack or break. Polypropylene
is relatively soft, scratches more easily than acrylic or styrene and has
a frosted/milky appearance.
A material that is unbreakable,
will not crack or cloud, is microwave/dishwasher safe, heat and impact resistant,
will not discolor. Polycarbonate is used in the manufacture of bulletproof
glass and airplane windows.
