Active Agents , ZnCO3??, White powder??, Used for soles and other rubber products.

Recommendations?and?Applications:

ZnCO3?is?a?white?fine?amorphous?powder ,?odourless ,?tasteless.?

Soluble?in?dilute?acid?and?sodium?hydroxide ,?slightly?soluble?in?ammonia ,?insoluble?in?water?and?alcohol.?

React?with?30%?hydrogen?peroxide,?releasing?carbon?dioxide ,?produce?peroxides.

ZnCO3?Carbonate?is?very?important?material?in?rubber?industry ,?imparts?very?good?physical?properties,?

well?abrasion?resistance?and?corrosion?resistance?of?the?vulcanizates.

It?acts?as?a?accelerator?to?speed?up?curing?rate ,?

make?the?products?more?transparent?and?without?whitening?phenomenon.

It?is?used?to?produced?sulfur?vulcanized?semi?transparent?products.?

ZnCO3?is?able?to?significantly?increase?hardness?of?the?products ,?

but?with?a?worse?reinforcing?effect?than?ZnO.?

So?ZnCO3?and?ZnO?are?usually?used?together?to?produce?high?performance?products.

ZnCO3?is?used?as?foaming?accelerator?in?EVA?blowning?material ,?imparts?advantages?like?fast?blowning,?

low?heavy?metal?content ,?uniform?performance?of?the?product ,?good?mechanical?properties.?
