Thanks for the feedback.. My test was done with 70°C Water for three weeks. I'm pretty sure it reached maximum water absorption. Although the cable ties (which are Nylon 6/6) became brittle, they easily maintained the necessary strength. The product will not be exposed to those temps very...
I've got an application where I need to install cable ties to support a submersed product . the product weighs about 5.0lbs and will be strapped on a 2" pipe.. I know nylon is hygroscopic, but I've done some testing under hot water for about five weeks with positive results but I'm worried...
Thanks for the inputs. particularly the hard / elastomeric compatibility. I'll try to marry those couples whenever I can.
I found a claim on a website that plasma treated PTU will have excellent bond with PBT. It's an obvious sales pitch, so I'm not sure how much to believe it.
I've got a project that will be underwater. it needs a hard shell for rigidity (PBT). and a low pressure material (TPU?) to seal/enclose some electronics. we designed it such that, even if there is separation between plastics, the circuits are -almost- completely enclosed within the TPU but I'd...
