Product Description

When it comes to choosing a zinc oxide for general rubber goods, most manufacturers care about two things: stability and value. You don't always need nano‑grade activity, but you do need consistent batch‑to‑batch quality and a competitive price.

ZnO-A50 is designed exactly for that. It is a standard‑grade indirect‑process zinc oxide with a content of 99.5% or higher. Nothing fancy — just high purity, low impurities, and solid cost‑performance.

Yes, the powder form creates dust. But the real advantage is its wide compatibility. Whether you use sulfur curing or metal oxide curing, whether you work with thiazoles, sulfenamides, or guanidines, ZnO-A50 works reliably. For high‑volume general products like tyres, hoses, shoe soles, and EVA foams, it serves as a dependable workhorse.

In CR (chloroprene rubber) compounds, ZnO-A50 can be used together with magnesium oxide to improve scorch safety and heat resistance. That is one reason why this basic grade remains a long‑term choice for many rubber factories.
