Does anyone know of an efficient way to compress/compact/extrude/pelletize the loose nylon fibre generated from crumb rubber operations? I produce approx 10 yards a shift of very loose,approx 1" strands of fibre w/fine rubber dust. I would like to briquette this material for fuel stock.

Tell us the type of Nylon (Nylon 6, or 6-6), and we can tell you it's melting point. Regardless though, Nylon's have a very pronounced and sharp single melting point.

Once revelaed, you can try to compression mold this fluffy stuff, after you spin it into something formable.

My thought is to heat it and allow it to return to it's somewhat original form or collect it in "bloobs".

Thanks for the reply. I am not sure of the makeup of this fluff, I suppose I could get the Info from the tire manufacturer? Anyway, wouldn,t you be a little concerned with the rubber dust if heating?

Sure, the rubber dust will smell awful, but if you vent the fumes outdoors, this should'nt be a problem.

Polyamide Melting Points (all in degrees C):
Nylon 6 = 210-220
6,6 = 240-265
6,6/6 =240
6,9 = 205
6,10 = 195-220
11 = 195-217
12 = 190-200
Aromatic polyamide (Aramid) = 275
Poly amide imide = 270-280

My best guess is that "current tires" uses Aramid, as the 6 series absorb moisture and allow for "flat-spotting" (parking your car overnight then driving in the morning would produce a "thump-thump" each revolution. "Older" tire used the 6 series, but that was decades ago.
