<FONT FACE="ARIAL,TIMES NEW ROMAN"><B>INTRODUCTION</B></FONT><BR>
PureTherm ESD1500 is a high-clarity, static dissipative, rigid PVC based plastic sheet. This
thermoformable product for trays, lids and clamshell containers, provides superior structural
and electrostatic protection for sensitive electronic components. PureTherm ESD1500 meets or
exceeds Military Specification MIL-B-81705-C, EIA-541, EOS/ESD S11.11 and Bellcore GR-1421-CORE
requirements for surface resistivity and static decay at 12% relative humidity. Available in
<NOBR>10 to 40 mil,</NOBR> the proprietary PureTherm ESD1500 process is non-humidity dependent
and offers long-lasting shelf life.

<FONT FACE="ARIAL,TIMES NEW ROMAN"><B>PRODUCT TESTING</B></FONT><BR>
PurePlast Inc. (PPi) tests physical and electrical properties and qualifies all materials
at the PPi Cambridge, Ontario technical center under rigorous test conditions by simulating
various environments and accelerating the aging process. When standard industrial or governmental
test procedures exist, PPi verifies internally generated results with testing at
appropriate independent laboratories. Documentation is available upon request.
<P>
<FONT FACE="ARIAL,TIMES NEW ROMAN"><B>PRODUCT CERTIFICATION</B></FONT><BR>
PPi certifies, with every order, that the electrostatic properties of PureTherm ESD1500
are in full compliance with the requirements for static dissipative materials as described
in EIA-541 and EOS/ESD S11.11. PPi will certify similar compliance with Bellcore GR-1421-CORE
on request.
<P>
<FONT FACE="ARIAL,TIMES NEW ROMAN"><B>BELLCORE TESTING</B></FONT><BR>
PureTherm ESD1500 material when tested meets or exceeds the folllowing Bellcore generic
requirements as in the document GR-1421-CORE, issue 2, June 1995 entitled "Generic Reqirements
for ESD Protective Circuit Pack Containers":
<UL>
<LI>Surface Resistance at 12% and 50% Relative Humidity
<LI>Material Charge Generation by Modified Incline Plane Method
<LI>Outgassing
<LI>Temperature Cycling
<LI>Temperature and Humidity Stability
<LI>Flexing and Closure Hinges
</UL>
Above tests have been performed on clamshell containers using PureTherm ESD1500 material
at <B><NOBR>30 mil</NOBR> thickness and drawn to a depth of 2.5 inches</B>. Independent laboratory test
results are available upon request.
