Grade selection guide

How to clean effectively
Must choose the most suitable grade

Choosing the right grade is important for effective cleaning, and the resin polarity has a large effect on whether or not it remains. Please select the grade of Celpurge referring to the following points.

Point 01

Determine by classifying each resin

01olefin resin,
02engineering plastic / ABS resin,
03super engineering plastic

The effective cleaning mechanism is different for each resin.

Point 02

Consider not only preceding material but also subsequent material

It is important to prevent residue of purge agent.

Olefin resin
Due to its low discharge capacity, engineering plastic grades such as NX-VN2 may not be discharged well. In the color change of olefin resin and the material change of olefin resin after material,Please select the olefin grade such as NX-VC2, NX-E, NX-P2S.
For resins with high processing temperatures such as super engineering plastics
Please select NX-HG for high temperature resin cleaning. When used for super engineering plastic applications, it is recommended to dry before use.
To change materials from engineering plastics to olefin resins
Eject engineering plastics with engineering grades (NX-VN2, NX-VK2, NX-VG2, AW2), Then discharge the engineering plastic grade with olefin grade (NX-VC2, NX-P2S, NX-E), 2 steps cleaning is recommended.
For black spots and carbonized foreign material cleaning
Please select NX-VG2 with GF. It is more effective to use NX-VN2 after NX-VG2. Please use 2: 1 without mixing. (If it is a slight black spot, the grade with no filler added is also effective.)
Uses Celpurge for sealing
It can also be used as a sealing material. After completing the purge with the Celpurge, Sealing can prevent the carbonization during stopping the molding machine.
* Please use non-filler grade for sealing.
Celpurge as take out screw agent
Please use the grade NX-BS. It reduces the work load when removing and cleaning the screw.

If you are facing the problem about the grade selection
Please try to refer the flow below.

Is the color changed? What resin do you want to purge?
Is the material changed? What resin (subsequent material) is to be molded next?
Remove black dots and carbon? What resin (subsequent material) is to be molded next?
