The Zinc Oxide Grade (99.0%) available with us is formulated as per the international standards and are extensively used in different industries owing to its 0.35 loss on ignition at 950ºC, % by mass (max.). Our range bears a pH value (10gm/100ml) of 5.0 - 8.0 and finds wide application in rubber industries for preparing: - Rubber gloves
- Rubber foot wears
- Rubber hosepipes
- Car rubber mats
- Rubber seals
- Domestic & Industrial rubber products
