Dear Biomch-l subscribers,

About a week ago, I posted a message regarding polyethylene and titanium
microparticules. Here is the original message:

> Dear Biomch-l subscribers,

> I am looking for a company which could provide me very small particles

> polyethylene (UHMWPE) and of titanium oxyde.

> Thanks in advance for your help.


These are the suggestions I received (I did not have time to check
them):
