ACRAS™ Tapered bristle
ACRAS™ is a polyester monofilament brush hair material that is tapered at the end. Notably, this tapering is achieved by chemical processing, so that it is uniform in shape and has a very smooth surface. Because of this feature, when used as in a toothbrush, it fits well between the teeth, cleans the teeth well, and has a soft texture. When used for a writing brush, it exhibits properties just like those of natural hair.
