1. Is PurgeMax® easy to use?
PurgeMax® is extremely easy to use. Just toss the whole packet of PurgeMax® into hopper.
2. Is PurgeMax® safe to use?
Yes, PurgeMax® is heat stable, non-toxic, non-hazardous, non-flammable and safe to use with
heat ranges from 135 o C to 400 o C.
3. Can PurgeMax® applicable to most of industrial processes?
Yes, PurgeMax® can be effectively used for all types of thermoplastic resins in Injection
Moulding, Extrusion and Blow Moulding applications.
4. Can I mould parts with PurgeMax®?
Yes, PurgeMax® is mouldable and can be safely injected without damaging the mould.
5. What is the saving of using PurgeMax® versus regular purge?
Based on our manufacturer’s R&D cost evaluation and customer’s case studies, PurgeMax® helps
to reduce downtime up to 80% and reduce the scrap up to 85%.
6. Is PurgeMax® abrasive?
No, Purgemax® uses surfactant technology in cleaning and thus it is non-abrasive.
7. Will PurgeMax® helps to eliminate black specks / carbon build-up?
Yes, PurgeMax® removes black specks / carbon build-up. We recommend a regular purging with
PurgeMax® whereby every after a colour change, material change and during shutdown or start-
up period, it will gradually minimize the black spec problems.
8. How long is the soak time needed?
No soaking is needed. Allowing PurgeMax® to soak more than 1 minute will not enhance its
9. Is PurgeMax® certified?
RoHS compliance, EN71, and EU Food Accredited.
10. How long does it take to purge a machine using PurgeMax®?
The timing subjects to the condition of machine and type of resins used for cleaning. We suggest
a normal timing range from 10 minutes to an hour which depends on its machine tonnage.
11. What should I do with the PurgeMax® scrap?
PurgeMax® scrap can be handled in three ways:
a) It can be sold to the scrap collectors.
b) It can be reused as a carrier for the future of cleaning purposes.
c) It can be reused for a darker colour parts.
12. Does PurgeMax® leave a residue after purging?
No, PurgeMax® does not leave any residue because it does not stick to any kinds or metal.
13. How much is the consumption of PurgeMax® needed for each purge with Injection Moulding
Refer to PurgeMax® Usage Chart.
14. Is it safe to purge Hot Runners with PurgeMax®?
Yes, PurgeMax® is designed to clean Hot Runners and manifold. In many cases, it can also be
moulded. We have two different procedures for purging Hot Runners, with mould open and with
15. What should I know about purging heat sensitive resins?
PVC and material with FR filled are heat sensitive resins. Carbonization due to heat oxidation can
lead to degradation within just a few minutes. Therefore, we recommend to you not to empty
the barrel. PurgeMax® should be introduced at the end of the resin run by adding the PurgeMax®
on top of the resident resin in the hopper then followed by purging material. Continue to purge
until the resin appears to be natural and clean.
16. Does PurgeMax® contain any expansion agent?
Yes, PurgeMax® contains heat activator ingredients which help to clean the screw and barrel
17. Do I need to adjust the temperature profile?
Either maintain or increase 10% more.
18. What is the lifespan of PurgeMax®?
1 year from manufacturing date.
19. How do I know that the PurgeMax® solution in the barrel had finished?
It happened when the resin is clear and there is no bubble in the resins anymore.
20. Do I need to use specific material with PurgeMax®?
No, you may just follow the current purging resin used with PurgeMax®.
High Performance Cost Saving Purging Solution
21. It happens from time to time that after adding PurgeMax into the barrel such amount of foaming
material is created that it takes longer time when the granulate can enter the system. What can be
the reason for that?
PurgeMax reacts as polymer foaming agent to stimulate the cleaning process in the barrel which
could reach to the stubborn carbon area that hardly to be cleaned. It normally starts to form at
around 120 0 C and stops after 210 0 C. To reduce the time of foaming, you may increase the
temperature to above 200 0 C.
22. Is it normal if the liquid appearance separated as in the packet?
It is normal when the compound gets separated which you may slightly shake it to normal. It does
not affect the cleaning properties.
