TEXBLANK
YOUR BLEACHING AND MERCERIZING RANGE SOLUTION

An outstanding black elastomer, developed to resist the worst chemical conditions of the textile impregnation, bleaching and mercerizing padders: high temperature with oxidizing and alkaline products such as caustic soda and hydrogen peroxide

AVOID THESE PROBLE MS WITH TEXBLANK AND EXTEND TOUR ROLLERS' SERVICE TIME
Gomplastí»s TEXBLANK is a superb black rubber formulation specially designed to resist aggressive environments. Its unique base-polymer has a polar and highly saturated molecular structure that allows it to resist the strongest chemical conditions keeping unaltered its mechanical properties.

Can you identify the look of your impregnation, mercerizing and bleaching roller surfaces in the following pictures?

TEXBLANK proves its true potential when exposed to high temperatures (it can resist up to 140oC) and oxidant products (such as hydrogen peroxide and caustic soda), resisting its chemical attack for several years and extending the lifetime of both the covering and the metal core of your rollers. You will never see these chemical attacks again on your rollerí»s surface.

TEXBLANK keeps its viscoelastic properties unaltered allowing a uniform absorption of your chemical treatment inside the fabric that will avoid future problems of uneven dye application.

TEXBLANK BEATS OTHER EXISTING COVERINGS IN ALL STUDIED DATA
When comparing TEXBLANK to a regular covering, field observation indicated that Gomplastí»s elastomer performed better in all given data, being the bigger differences in hydrogen peroxide and ozone resistances. All these improved properties allow the TEXBLANK roller to achieve a much longer service life on the bleaching train reducing dramatically the production costs caused by damaged rollersí» changes, both in time and money.



TEXBLANK ADVANTAGES
Excellent aging, weathering and ozone resistance
Working temperatures up to 140íŠ
High chemical resistance to oxidizing materials such as NaOH and H2O2
Reduces dramatically production's stops for changing damaged rollers
Ensures an homogeneity on the chemical bleaching treatment yielding an outstanding dyeing of your fabric
Avoids contamination between boxes
Several service life years
