Tough PLA chemical comnposition

[pineirod 2]

Hi there,

 

I would like to know the chemical composition (formula) of the tough PLA. We want to study their radiation length.

 

The idea is know how much it "blocks" particles in a nuclear physics experiment

 

thanks

I guess you have access to the data of standard PLA. The impact modifier is probably a trade secret.

 

What particles do you use? In case you need a neutron absorber, you might want to have a look at AddBor N25 from Addnorth.

If you want to use TPLA as some kind of beam dump you also might want to keep an eye on the deposited energy as PLA has a pretty low heat deflection temperature.

Hi,

Do you think the impact modifier would make a big difference in the radiation length?

 

We don't need absorber, but a shell to close the detector (PWO crystals).

 

We want to see the effect of the material in front of the crystals

 

thanks

Well, of course I don't know the volume percentage of the impact modifier but what can be googled it seems fractions up to 30% are possible. Depending on how different the radiation length of that modifier is from PLA it can differ significantly.

 

What I probably would do is to print samples and make a test series with a stable radiation source. Especially I would compare the Tough PLA to Standard PLA of the same color and also to transparent PLA. You might also take other materials into consideration for such a test.
