  No though I know people have literally just used stuff like PAM in the past. Mine was a purpose made mold release agent that I picked up off McMaster Carr. They sell a lot of different ones The polypropylene I’ve used does not have fiberglass added. Though there are a LOT of options for thermoplastics, both ready made and custom mixed/compounded. You really learn to just go straight to the data sheet when thermoplastic shopping because that has all the relevant info you need
