ECOSTER SL - Is the most versatile of the non-flaggable fibers. Depending on the applications it is intended for, different degrees of softness, stiffness, elasticity and flexibility can be achieved. Adjusting the thickness and cut length to the functional requirements of the finished product, there is no application that cannot be covered by this remarkable filament. Two of the most outstanding features of this product are its great heat resistance and the round shape of its section; the latter greatly enhances its workability. Its resistance to abrasion and the special formulation that allows tipping make ECOSTER SL suitable for paintbrushes, even in blends with bristle and horsehair.
