green thermoplastic material
(OP)
I'm working on a new design of a custom black color end cap piece that'll function as a non-adjustable furniture glide for storage units. I'm looking for a least, preferably not carcinogenic material (definitely non-PVC) for injection molded process. Would nylon, LDPE or PP be appropriate for this application and environmental considerations? Thank you.

temp range?
sun?
water?
why black?

Different colour formulations can significantly alter the performance. Even 2 different blacks can have significantly different performance if one uses carbon and the other uses a dyestuff like Nigroseine.

That influences the rate of crystal growth, the number of crystals and the nature of the crystals as the material changes from liquid to solid phase.
The different crystal structure has a significant effect on physical properties.

As to your point about the polymer encapsulating the carbon black, it's a good point. A little research shows that the FDA actually approves carbon black for some food applications as it deems it a carcinogen only in the respiratory sense.
Still, knowing it's a carcinogen in any form would make me uneasy about calling it green considering it's dirty beginnings. (also, consider the workers at the plant who may breathe it in, I hope they've come a long way from this, but maybe not...http://www
I guess it all depends on how 'green' you want to make it

I wonder if the jury will decide the mine worker was at greater risk from the vast quantities of carbon he inhaled or the cigarette he's smoking.
