Requesting Additional Material File

Hello Andreu,

Thank you for adding the new material files recently. I was wondering if you could also add in the following material files:
- nylon
- PMMA
- glass
- PVDC
- aluminum oxide
- an adipose/glandular tissue mix of composition 50/50
- an adipose/glandular tissue mix of composition 30/70
- an adipose/glandular tissue mix of composition 70/30

Thank you!
Alex
