ManvsMini Posted January 17, 2019 Share Posted January 17, 2019 Ok, science: ON. *Disclaimer: I am not a formulation or polymer chemist, nor ever will be. But I have slept at a Holiday Inn Express, so here it goes... In PVC-based plastics, the polymer they use is PVC (shocker, I know.) But the actual plastic isn't solely the chemical polyvinyl chloride, it is a mixture of PVC with other chemicals that are called additives. It's the additives that alter the properties of plastics (that's generally speaking; the actual polymer used alters it to). Add certain compounds to the plastic mixture, and it can withstand higher temperatures, change the color, or how strong and flexible it is, etc. Additives called plasticizers are what make plastics flexible. PVC on it's own is pretty brittle. Add some plasticizers to it, and now it starts to become flexible, and thus more durable; PVC piping is a good example, it has enough to reduce the brittleness and to make it durable enough for construction purposes. Add even more plasticizers, and eventually you can get the flexibility of the original Bones material. *Note: other additives contribute to the properties of PVC piping and Bones, I'm just focusing on plasticizers. It's late where I'm at... Based on that, I think this is how the Bones material was achieved; it had a good amount of plasticizers in it. There are undoubtedly other non-plasticizer additives involved in the material contributing to it's properties; I am certain of that. If I am right on that, and if Bones Black is still PVC-based, then whoever formulated the Bones Black material probably reduced the plasticizers to eliminate the floppiness and the mold-line-scraping damage, but added other additives to enhance the detail-retention and all it's other properties. Of course, if the good folks at Reaper completely changed the base polymer they are using, then my hypothesis is wrong. Isn't science fun??? Ok, science: OFF. Thanks for letting me share. -MvM 8 4 Quote Link to comment Share on other sites More sharing options...
