It is an object of this invention to provide a yarn including a fishing line which comprises ultra-high molecular weight polyethylene filaments that have low elongation rate and adjustable specific gravity or show excellent abrasion resistance. It also provides a manufacturing method of said yarns and...
More preferable is 3% or less.The porosity (P) is defined as follows: P=(dth-dex)/dth×100PAL where dth is the true specific gravity of the barrier rib material and dexis the measured density of the barrier ribs. It is preferable to calculate the true specific gravity of the barrier ...
“μg” means microgram(s), “ng” means nanogram(s), “g” means gravity, “HPLC” means high performance liquid chromatography, “dd H2O” means distilled and deionized water, “dcw” means dry cell weight, “ATCC” or ATCC®″ means the American Type Culture Collection (Manassas, Va...
4. The toner of claim 1, wherein the alkyl carboxylic acid has a specific gravity of 0.7 to 0.8 g/cc. 5. The toner of claim 1, wherein an amount of addition of the organic fine particles is in a range of 0.01 to 5 parts by weight with respect to 100 parts by weight of the...
The specific gravity is usually from 1 to 12, preferably from 3 to 6. The tap density is from 0.05 to 2 g/ml, preferably from 0.2 to 1.5 g/ml. If the tap density is less than 0.05 g/ml, flying of many particles occurs and the operation becomes difficult, whereas if it exceeds 2...
