Silicone like material with more optical transmission

Can someone recommend a silicone like material that would pass more light than silicone in compressing? For example if we would like to create an ipod case that would illuminate (with small amount of LED) were should we look?

Philips use to have a wearable electronics division and did house/pioneer such things. They may still be going!

Are you limited to compression molding? If not, then there are plenty of TPE’s and TPU’s that have good optical properties with injection molding. If you are stuck using compression molding, then your choices are slimmer. Though you can spend the money on good (really clear) silicones and probably achieve your desired result. Good luck, and let us know what you end up using.
