St. Louis - Feb. 20, 2013 -Spartech Corporation (NYSE: SEH), a leading producer
of plastic sheet, compounds and packaging products, today announced that its
Royalite® R59, R574 and R926 flame retardant specialty sheet products pass the
ball pressure test for heat resistance.

The ball pressure test determines an insulating material's resistance to
elevated temperatures while under stress. This is vital for materials used in
medical device housing and casings such as MRI machines and CT scanners. The
plastic is strong enough to resist high heat distortion during use, such as
sagging, and eliminates any operating interference that may occur from using
metal casings.

"Passing the ball pressure test allows us to better serve our customers in the
medical equipment industry," said Eric Lattanner, Royalite Product Manager at
Spartech. "This is truly a   competitive advantage for Spartech and our customers
because it ensures our products will consistently perform even under the most
strenuous conditions, allowing doctors and other medical personnel to better aid
their patients."hermoplastic alloy designed for applications which have the most
stringent flame and smoke requirements. It is a thermoformed product solution
available in a wide variety of colors and textures.

The following products pass the ball pressure test:

·         Royalite R59 - A flame rated PVC/ABS product ideal for various
applications including medical equipment, electronic appliances, and mass
transit.

·         Royalite R574 - A RoHS compliant, flame- rated ABS product that does
not contain any PVC or PBDE.

·         Royalite R926 - A non-halogen, flame- rated PC/ABS product that is
perfect for a wide variety of applications in the medical, electronics and
transportation industries.

In the ball pressure test, a small steel ball is applied at a standard force to
a specimen material at raised temperatures until the ball produces an
indentation measuring at two millimeters in diameter. The temperature at which a
two millimeter indentation occurs is the measured result of the test.

The ball pressure test is an International Electrotechnical Commission (EIC)
Standard. The EIC is the leading global organization that publishes consensus-
based International Standards and manages conformity assessment systems for
electric and electronic products, systems and services. All Royalite specialty
products that pass the ball test are UL listed in accordance with IEC
60695-10-2.
