Product Specification

IQRA Specification

IQRA has a full – fledged structure that has been designed in the most meticulous way to provide the exact product that is needed by its clients.

Since Silica is a natural material found underneath the ground surface, the physical & internal components differ from region to region. There are two significant things to keep in mind for this natural resource, one being the external structure (appearance & size)& the other being the internal structure (chemical composition). The chemical composition & size of our product range are very important factors for IQRA’s customers. Every customer has a different requirement depending upon where they will be utilising our product in their industry. Their needs come with certain standards & specifications.

Based on our customers’ specifications, we deliver the product by keeping our quality values in mind. The standard chemical specifications of our products have been listed below. The sizes of each product can be customised based on the requirements of our customers.
