HT-2C
Zinc oxide
Hydro Technologies (Canada)
ï

General purpose ZnO; BET 4-7 m2; sp.gr. 5.6; cream to off-white powder

NR and SR activator; semi-reinforcing and hiding pigment.


HT-Active
Zinc oxide
Hydro Technologies (Canada)
ï

High surface area ZnO; BET 40 m2; sp.gr. 5.6; cream to off-white powder; zinc content > 97%; Pb content <25 ppm

A 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.


HT-3C
Zinc oxide
Hydro Technologies (Canada)
ï

General purpose ZnO; BET 4-8 m2; sp.gr. 5.6; cream to off-white powder

NR and SR activator; semi-reinforcing and hiding pigment.


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.


HT-10
Zinc oxide
Hydro Technologies (Canada)
ï

General purpose ZnO; BET 8-11 m2; sp.gr. 5.6; cream to off-white powder

Medium surface area ZnO; NR and SR activator; semi-reinforcing and hiding pigment with higher activity; useful in adhesive formulations as a latex activator and supplemental gelling agent.

Zinc Oxide Transparent
Basic zinc carbonate
Lanxess Corporation
ï

Sp. gr, 3.5; white to light yellowish powder; zinc content as zinc oxide approx. 72%; shipped: bag.

A very highly disperse accelerator activator without pigmenting properties; excellent in the manufacture of transparent rubber goods and adhesives; acts as an activator in latex applications


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
