Crumb Rubber ASTM Testing
Project Description
Polymer Laboratory needed to perform the relevant ASTM tests (i.e ASTM D6814-02 and / or ASTM D 297-15.) to measure the percentage of devulcanization of a polymer (i.e the reduction in crosslink density).
In our case we've devulcanized crumb rubber that was derived from whole end-of-life-truck tires.
Please provide a quote for between 6 to 8 samples of devulcanized rubber in the form of 2mm pellets. In addition we can ship you cross linked crumb rubber feedstock for the control.
I propose sending you 20 grams of each. I can certainly send you less or more. 100 grams? 200 grams? Just let me know the optimal amount you need.
Our main goal is to measure the crosslink density.
Ideally we would also like a Horikx analysis and plot. Are you able to measure the amount of sol fraction so that we can determine how much main chain scission took place vs. how much crosslink scission occurred?
As you know, a Horikx?s analysis determines the relationship between the soluble fraction of rubber and the relative decrease in cross-link density after devulcanization. The analysis can be used to identify and illustrate whether the degradation of a polymer is dominated by random chain scission or the selective breakdown of cross-links (i.e. devulcanization). There are two different scenarios: random chain scission and scission of the cross-links.
