How to make photoluminescent plastic

These are the guidelines for using Photoluminescent pigment in Plastic. You can use our photoluminescent plastic pellets or Master Batch instead saving you time and money. See how to use photoluminescent plastic granule or master batch for details. 1. You can mix photoluminescent pigment in with acrylic, polyester, polypropylene, epoxy, PVC, polyethylene (HDPE, LDPE etc) polymers. 2. You can extrude, mold, dip and cast this material. 3. Use less photoluminescent pigment than other ZnS:CU luminous pigments. 4. Keep the temperature low as possible while extruding. 5. Master Batches of photoluminescent material must be completely dried up before usage.

Master Batch Manufacturing

1. Clean the interior of the extruder before manufacturing with the plastic master batch. 2. Keep the resin and pigment dry before the extruding process is started. 3. It is recommended to use a machine with twin hoppers and a distributive screw design. Use one of the hoppers to feed the resin and additives and the second for the photoluminescent pigment. Doing so will decrease the abrasion to the extruder surfaces. 4. Do not stir for a long time because this might darken the pigment/resin. 5. Keep the processing temperature 10 degrees higher than a normal run of plastic. 6. Clean the extruder again by running clear resin through until clear resin can be seen coming out of the extruder. 7. Use ceramic, glass or hard metal containers because the photoluminescent pigment will react to heavy metals causing discoloration. 8. Mix the photoluminescent pigment with liquid paraffin. Ratio of the liquid paraffin to the plastic particle is 1 -1.5% of the plastic particle. 9. Using the white mine oil makes the photoluminescent pigment stick evenly with the plastic.
