<P align=left>Many important factors must be dealt with for proper processing of CYCOLAC resins.<br>Temperature control is the key in both drying and molding.CYCOLAC resin is mildly hygroscopic and absorbs moisture in direct proportion to the surrounding relative humidity; the process is reversible, i.e., wet pellets will lose moisture to air with low relative humidity.When CYCOLAC resin is exposed to humidity, the moisture is absorbed onto the surface and into the interior of the pellet, regrind particle or molded part. Dry pellets will absorb moisture until the content reaches an equilibrium with the moisture in the air. The exact amount of moisture content depends on the relative humidity, how long the resin was exposed, and on the grade of CYCOLAC resin. Typical equilibrium moisture con-tents at 50% RH range between .25 to .65%; at 80% RH from 0.55 to 1.4%-depending on grade. How fast the equilibrium amount of moisture is absorbed depends on particle size and temperature;smaller particles and higher temperatures cause more rapid absorption.Processing undried CYCOLAC resin can result in splay, splash marks or silver streaking <FONT size=3>on </FONT><FONT size=3>molded</FONT> parts.</P>
