Applications

PVCApplications that require moderate chemical resistance and excellent ozone resistance. E.g.: Hoses and belts.NP 2174 0,7 33 78

CaCO3 Low temperature �exibility and excellent wear resistance.E.g.: Sealing rings, gaskets, hoses e friction materials.NP 2170

NBR

0,7 28 57

CaCO3 Indicated for calendering and extrusion, excellent super�cial �nishing, low shrinkage, low swelling.E.g.: Hoses, conveyor belts, adhesives and sections.

NP 1021 0,7 30 80

CaCO3 Excellent performance in dynamic applications. E.g.: Hoses, cover laminated, belts, friction materials and rice peeling machines.NP 2007 0,7 30 94

CaCO3

For transfer and injection molding, due to its excellent �ow.Presents excellent Performance in blending processes, both in open and closed blenders, quick dissolution in polar solvents. E.g.: Adhesives, retainers, rings and gaskets.

NP 2012G 0,7 33 27

CaCO3 Excellent stability, low shrinkage, elevated dimensional stability, good mechanical properties. Indicated for opaque artifacts.E.g.: PVC soles, hoses and pro�les

NP 3083 0,7 33 38

CaCO3 For extruded artifacts, low swelling, elevated resistance to traction, excellent deformation by compression. E.g.: Low-hardness printing rollers, gaskets, sheets, rice peeling machines, and friction materials.
