Switching from BASF Ultramid B3S Nylon to EnviroLon 6?
Switching from BASF Ultramid B3S Nylon to EnviroLon 6?
(OP)
It has been requested that we look into making our non structural parts out of a recycled nylon called EnviroLon 6 (unsure of manufacturer). I was able to find mechanical properties for BASF Ultramid B3S Nylon, but I wasnt able to find any information on EnviroLon 6. The guy who does our molding suggested the switch because of cost, but I need to verify that this will be a good substitute. How different are these two formulations, and will their mechanical properties i.e. brittleness and strength be much different?
Thanks,
Jeff

It largely depends on the feedstock being recycled and how it is then handled and reprocessed.
It could be anything from recycled tyre cord waste from looms which generally has very good physicals but poor colour to reclaimed film which also has very good physicals but is hard to mould to reclaimed very fine mouldings made from super fast cycle grades which have poor physicals.
The real risk is it will be variable in physicals, colour and processing parameters.
It's properties will also depend on colours used and processing conditions during original use, re compounding and your processing.

I think the person telling you to do that is unaware of the reality. It's easy to say it's cheaper but it will not perform like a virgin product. If you can accept recycled nylon I start to wonder whether the parts are overspecified to begin with. In which case why not switch to virgin PP? Then you'll have the cost reduction without the variability of recyclate.
