Need help with a plastic selection or something similar
(OP)
Hi I hope someone can help.
I am in need to find a material to replace the current material on my design of a LED golf ball. The inner core casing that holds the LED's is made from PC plastic how ever it cracks under a lot of force from getting hit by a golf club. I am in need of a material here that is clear, that can be made into a mould, that can hold at a min amount of heat as PC before melting and main thing cant be broken or can flex to stop the cracking under force.
Look forward to your reply.
Brad

Quality, quantity, cost. Pick two.

... unless it comes in contact with anything resembling a solvent.
The list of substances that can cause Environmental Stress Cracking in PC is too long to copy here, but you can easily find it.
PC doesn't ordinarily fail by cracking from stress alone; the cracking strongly suggests ESC as a cause. The problem is that the exposure can occur anywhere in time prior to the application of stress, so you could be looking at environmental attack by the overmolded cover, or by anything that's used to wash/clean the PC during manufacture.
This would be a good time to walk the production line and record all the substances used on or even in the vicinity of the PC. Bring along some samples of the PC part, swab or dunk one in each substance, then hit it with a hammer. The difference will be immediate and dramatic.

So with that info there is no possible way that PC should be used in this. I have cut open a new ball and the inner core was not cracked at all. then after a ball had been hit a few times I cut it open and the core is basically shattered.
So if thats the case. What is the best material to try? TPU, truebloods suggestion of silicone, matt and nylon or block polyether/polyamide or are there any better options?

Have a look at this stuff: Amorphous PA12
Should do the job. (I believe equivalents are available - by whom I don't know - sorry)

As full disclosure, I work for one of Arkema's polyamide plants, but we don't make rilsan clear.

The rilsan clear look very promising but how is the price on that?
RE: Need help with a plastic selection or something similar
Pricing of any polymer is dependant on geographical location.
