CR 4 USP
Zinc oxide
Western Reserve Chemical
ï

White powder; 99.9% passes through 325 mesh; sp. gr. 5.6; 99.9% zinc oxide; heavy metal content, carbonate content and alakalinity pass USP tests.

Activator; meets USP specifications.


Zinkoxyd Aktiv
Zinc oxide
Lanxess Corporation
ï

Sp. gr, 5.0; white to light yellowish powder; zinc oxide content min. 93; BET surface area approx. 45 m2/g; shipped: bag.

A very highly disperse activator; excellent for the manufacture of semi transparent rubber goods or goods with reduced zinc oxide content; when added at high levels imparts improved shape retention and provides highly elastic vulcanizates; used as an activator in latex compounds resulting low levels of zinc in latex compounds


CR-4G
Zinc oxide
Harwick Standard
ï

High purity French process, white granule/pellet sp.gr 5.6; medium particle size, medium surface

For natural and synthetic rubbers and latices as cure activator and/or vulcanizer; add directly to rubber; pellet grade provides less dust


HTR
Zinc oxide
Hydro Technologies (Canada)
ï

High surface area ZnO; BET 30 m2; sp.gr. 5.6; cream to off-white powder; zinc content >97%; Pb content <25 ppm

Slightly lower in surface area than HT Active; highly dispersible zinc oxide especially suited for semi-transparent and latex compounds; its higher activity benefits compounds with reduced zinc oxide content; when used at higher levels, improves compression set, crosslink density and reduces cure time.


CR-420
Zinc oxide
Harwick Standard
ï

High purity French process, white powder sp.gr 5.6; small particle size, high surface and surface treated with propionic acid

For natural and synthetic rubbers and latices as cure activator and/or vulcanizer; add directly to rubber; treated grade provides easier, faster incorporation


CR 40
Zinc oxide
Western Reserve Chemical
ï

White powder; 99.9% passes through 325 mesh; sp. gr. 5.6; 99.9% zinc oxide; surface area 5 m2/g; surface treated with propionic acid.

Activator; surface treated to improve dispersion into rubber.
