Unique Product Questions
These questions are very specific but have been asked in the past. These are specifically here as a resource for the AI to crawl to better help you.
Is there any place where we can order swatches?
While we do not currently offer swatches, a third party does seem to make options of our materials. This company is not related to Polymaker, but you can see some of their options for our materials HERE
Was PolyMax™ or PolyLite™ PC called either "PC-Plus" or "PC-Max" in the past?
This name change occurred quite a long time ago, but yes.
PolyMax™ PC was PC-Max PolyLite™ PC was PC-Plus
Do you have any suggestions for a wear resistant material similar to SLS igus' iglidur i3-PL-10000?
While we have not done testing or comparisons, CoPA or PA612-CF15 may be the best options to try.
Can you provide a US location and phone number for any SDS documents?
This is possible but may take us a few business days. Please reach out to [email protected] with the materials you need this for and we will work on creating them.
Previously made SDS documents with a US location: HT-PLA HT-PLA-GF
Do you have a UL certification for PC-FR? Can you make one?
I am sorry but PolyMax™ PC-FR (PC-FR) does not have a UL certificate (such as a UL Blue Card), but it has been tested for flame retardancy by SGS (included in the link I sent earlier) using the IEC 60695-11-10:2013/Cor.1:2014 Method B, which is equivalent to the UL 94 standard. The result achieved is V-0 classification, which is the highest rating for flame retardancy in the UL 94 test.
You can find our test results here: https://cdn.shopify.com/s/files/1/0548/7299/7945/files/PolyMax_PC-FR_Flame_Retardant_Report.PDF?v=1641463128
We do not currently have plans for UL certifications.
Is PETG safe around acetone?
The answer comes from the "CHEMICAL RESISTANCE DATA" section of the PolyLite™ PETG Technical Data Sheet. It states that the material has "Poor" resistance to strong acids, with a note explaining that "Poor" means the material becomes unstable upon contact with the chemical at ambient temperature. Acetone, a strong solvent, falls under this category. Thus, PolyLite™ PETG is not safe around acetone, as it will likely degrade or become unstable.
I have seen some people mention their hands get irritated when handling fiber filament printed items. Do you have any recommendations?
Ways to reduce irritation
Post-processing without exposing fibers
Minimize aggressive sanding that cuts into the fibers.
If sanding is necessary, finish with a very fine grit (e.g., 600+) to reduce sharp fiber tips.
Coating recommendations
Epoxy resin (thin layer) → Best for sealing fibers and adding durability.
Polyurethane clear coat (spray-on automotive type) → Easier to apply, good surface sealing.
Acrylic spray clear coat → Light-duty sealing, easiest method but less robust.
All these coatings will create a smooth surface that prevents fiber contact and can improve aesthetics and weather resistance.
Can you over dry CF-Nylon materials? Such as drying them when they are not wet?
Drying CF-Nylon when it's not wet won't hurt it, as long as you stick to the recommended temps and times. The real risk is overheating, not over-drying.
Is creep resistance on PET-CF significantly impacted by the lack of annealing?
There are several ways to improve creep performance:
1. Increase the wall thickness and fill density of the printed part to ensure that the printed surface under stress is printed in the plane direction rather than the Z direction.
2. We strongly recommend annealing, which will effectively improve creep. If annealing is not possible, we recommend setting the load-bearing surface as the printed bottom surface.
3. If deformation cannot be suppressed, we suggest adding a spacer to reduce some of the pressure.
Is it safe to cut PLA with a CO2 laser? Does your material contain any PVC or other materials that should not be cut with a CO2 laser?
Our PLA contains no PVC but it does off gas pretty dramatically. So unless someone has a VERY good ventilation setup, it’s going to be too toxic of an environment.
Long story short, it will cut ok with a CO2 laser, but we wouldn’t suggest it.
My Anycubic ACE Pro is giving filament tangling issues with your Matte PLA, why is this?
This is an issue specific to the ACE Pro setup and specific to Panchroma Matte PLA. We are not sure why this happens and we are investigating this internally. But again, this is specific only to the ACE Pro and Panchroma Matte PLA.
If you do a lot of drying cycles of a CF-Nylon, does the performance of the material degrade?
Repeated drying of CF-Nylons at the right temps shouldn't make it brittle or degrade it. Just make sure to not dry at above the recommended temperature.
Does any carbon fiber nylon material Polymaker produces contain PFAS?
There is no PFAS in any PA-CF formula.
Can I use automotive spot putty thinned with Acetone on Fiberon blends without compromising strength, warpage and temperature resistance?
Use of Automotive Spot Putty (Thinned with Acetone)
Spot putty can generally be used on nylon composites like PA6-GF25 and PA6-CF20, but there are a few key points to consider:
Acetone is not recommended for nylon-based materials. Nylon is partially sensitive to polar solvents like acetone, which can cause surface softening, swelling, or internal stress—especially on semi-crystalline polymers like PA6. This may lead to localized strength loss or stress cracking over time.
Instead, we recommend using epoxy-based or polyester-based fillers without strong solvent thinning, or using a plastic-compatible spot filler designed for automotive bumpers or nylon-based plastics.
Always test any filler or putty on a small section of the part before full application.
Polyester Resin Coating – Risk of Warpage
Your concern about heat from resin curing is absolutely valid:
Many polyester resins are exothermic during curing, with internal temperatures potentially exceeding 80–100°C, depending on volume and ambient conditions.
Since PA6 composites begin to soften above ~100–120°C (though not deforming severely until ~200°C), thin-walled or lightly supported parts could warp during curing, especially if clamped or unevenly supported.
If you want to use a coating approach, here are a few safer options:
Recommended Finishing Options
2K Epoxy Primer or Automotive Filler Primer
These primers offer good adhesion to PA materials (especially with mild sanding or adhesion promoters) and are thermally stable during curing.
Automotive Plastic Adhesion Promoters
Use an adhesion promoter formulated for PA or PP surfaces before applying topcoats or fillers.
Low-exotherm Epoxy Resin Coating
If you want a resin coating, choose a low-exotherm epoxy system designed for composite surface smoothing. Test on a small part first to ensure dimensional stability.
Mechanical Finishing + Paint
For the cleanest result: sand, apply filler primer, re-sand, and finish with automotive paint system designed for plastic body parts.
Summary
Avoid acetone-based spot putty directly on nylon parts
Polyester resin could cause warpage—use with caution or avoid for large/thin parts
Use plastic-compatible fillers, low-exotherm coatings, or primer-filler + paint stack as a safer approach
Do you have materials with biocompatibility?
At this time we do not have a material that has passed the rigorous testing for biocompatibility, but we are working on this.
Why do the PLA products carry a proposition 65 warning for benzene?
This was a judgement from the Product Team. The hypothesis was benzene is a common used ingredient, CA-65 require manufacturer to list at least one material, but we could not test all of our products so the product team decided to list Benzene on the sticker. It doesn't mean our products carry benzene.
We may do further testing in the future to see if we can remove this label.
What is the moisture content of Fiberon™ materials at the time of packaging?
All Fiberon™ filaments are dried and vacuum-sealed to ensure a moisture content of less than 0.3%. Based on our batch-level tests, typical results fall under 0.15%.
Do you dry Fiberon™ filament after water cooling during extrusion?
Yes. All Fiberon™ filaments undergo a dedicated post-extrusion drying process before winding and packaging.
Why does printing ESD materials at higher temperatures drastically reduce resistance?
Higher print temperatures improve the mobility and dispersion of CNTs (carbon nanotubes) in the polymer melt, allowing better network formation. This enhanced connectivity reduces surface resistance, sometimes by multiple orders of magnitude.
Do you have EN71-3 testing for the EU for toys for any products?
As of right now we do not. But this is something we are currently looking into.
What Polymaker filament offers resistance to common paint thinners/solvents?
PPS would be the best option for this, so we would suggest either Fiberon™ PPS-CF10 or Fiberon™ PPS-GF20.
How does the poly dryer work and how come it is the same fan and heater making 3 different power levels?
The adjustment of settings and temperature is mainly achieved through current regulation. The fan speed (RPM) and air volume flowrate are fixed and do not change to adjust the settings. Similarly, the heater power remains constant; however, the overall power consumption varies depending on the target temperature and changes in air temperature, which is mainly caused by current regulation.
Please find below the relevant specifications of the fan.
What material would you suggest that is small like this and creep resistant?
The best option for this would likely be PolyMax™ PC.
Do you have any information about the dissipation factor of the PPS-GF20 material?
We have not tested dissipation factor before.
We've done some checking and we do have small doses of other components in our formulations for improving the printability of the material, and these may cause an elevated dissipation factor, but we don't have specific values to provide. It is recommended that corresponding tests be performed under the parameters of the specific application.
Also we understand that the high crystallinity of PPS helps to reduce the dissipation and dielectric constant, and it is recommended to anneal the material at 130 degrees or 230 degrees before testing.
Also, there are values for dielectric constant in TDS that may help.
