The PL pigment has been widely used in plastic products, such as plastic toys, plates, tapes and switches. These PL plastic products are very convenient for daily lives and are facing good marketing prospect.

PL pigment can be used in different process such as injection molding, extrusion, pouring, calendering, banbury and so on. You can get better luminous effect in this way: first, manufacture luminous masterbatch; then make luminous plastic material with the luminous masterbatch.

Confection of pellets:

Transparent resin 40--60
PLpigment 5-50
White oil Little
Lubricant assistant 5-10
dispersent 1-2

The transparent resin can be PP, PS, AS, PVC or transparent PE, or sometimes can be opaque ABS.

Mix the above-mentioned material evenly, put it into the extrusive machine to be processed under the normal temperature. When cooled down, cut it into pellets.

Suggest:

1. > Use the glabrous machine, reduce the friction, decrease damage to machine and lessen the contamination to PL pigments.

2. > Because the size of PL pigment particle is big, we can produce the pellets using screw machine without filtering screen.

* The effect of luminous plastic material will be well if made of luminous masterbatch. And the ration of the Photoluminescent pigment in the plastic material is between 1—10%. You can adjust the ratio of luminous masterbatch and white material according to different brightness request. Usually the ideal Photoluminescent pigment ratio is 4—5%.

* Injection products can be made in one time, just stick the PL pigment evenly to the surface of pellets.

* You can manufacture plastic plates, chips, tubes and threats by PL plastic pellets.

Suggestions:

Coarse producing equipment or complex technics will do harm to the manufacture of PL plastic products.
Do not stir the materials with metal facility in high speed, you should stir it in the lined vessel.
