Product Overview
Description
Product DescriptionProduct Description
Basic zinc carbonate(Transparent Zinc Oxide Powder), is a kind of inorganic carbonate, mainly as a raw materials of ceramic and
lithopone manufacturing. It’s specially used in transparent rubber products because of its refractive index similar to rubber.
Bellow are the advantages in application in rubber:
1. It is able to increase the thermal conductivity glue, improve the thermal conductivity and the curing rate, especially suitable
for hot air vulcanization process.
2. It can improve the stability of the shape of semi-finished products in the curing process, which is suitable for non-model
products (such as the based products which is the use of continuous vulcanization technology)
