Purging Guidelines:

For best ZYLAR trial results, a thorough purging of the molding machine prior to running ZYLAR is critical as any contamination left in the barrel, hot runner system, or mold can result in hazy parts.

The preferred purge material is NAS. The best NAS purge material for running ZYLAR 220 or 221 is NAS 21. For all other ZYLAR grades, NAS 30 is recommended for purging. If NAS is not available for purging, crystal polystyrene is an acceptable alternative and better than leaving another higher temperature material in the machine.

If the material that was being used in the molding machine prior to the ZYLAR was run at a higher barrel temperature profile (ex. Polycarbonate @ 550°F or PMMA @ 480°F), then it is best to re-heat the machine initially to those same temperatures. Then, flush the appropriate NAS material through the unit until it runs clear before dropping the temperatures to the recommended ZYLAR conditions. After cooling, flush with a few pounds of ZYLAR.

If the material being used prior to the ZYLAR was run at a lower temperature, then heat the machine up to the desired settings for running ZYLAR and follow the above procedures for purging first with NAS, and then ZYLAR.

Flushing the machine until you see a clear ZYLAR purge patty is not critical. In fact at high temperatures ZYLAR can be very hazy, and the patty will hold a hot temperature for an extended period of time. Ejected molded parts may exhibit this same haziness until cooled.

For NAS trials you can follow the procedures above, excluding the use of any ZYLAR materials.

Finally, if present, any tiny streaks of white, colors, or haze can be an indication of contamination in the machine. If this occurs then continue to purge the system.

Drying:

Drying is not always necessary. If the molded parts are very large or the Plant is located in a very humid region, then you may need to dry the material according to the instructions on the front of this technical bulletin. This is only needed for surface drying of the material, as it will not absorb large amounts of water. The effects of not drying under the above conditions are strictly esthetic, and will not affect the physical properties of the final parts.
