Special Features

Typical application

N220

High resistance to abrasion and tearing.Relatively low modulus and easier dispersion than N110

Reinforcing black for tyre treads.High quality industrial rubber products and high rating conveyer belts.

N330

Combines good abrasion resistance with moderate hysteresis properties.

Tyre betls,sidewalls.Solid tyres,roller covers,hose covers,hose covers,industrial rubber products Molded articles.

N550

The most reinforcing on the semi-reinforcing gtades,with excellent extrusion properties.

Tyre body and tubr compounds.Hose,exruded profiles,industrial seals and moldings.

N660

Compared withN550,less reinforcing.Lower structure and higher die swell.Higher loading capability

Tyre body and tube compounds.General moldings and extrusions.Single-piy roofing systems.
