summary

Styrene-Butadiene Rubber (SBR) Latex is a synthetic rubber emulsion produced by polymerizing styrene and butadiene. It is widely used in paper coating, carpet backing, adhesives, construction chemicals, and foam products due to its flexibility, bonding strength, and abrasion resistance.

Why BIS Certificate is Mandatory for Styrene-Butadiene Rubber Latex

BIS certification is mandatory for SBR Latex to ensure conformity with Indian Standards related to quality, chemical composition, performance, and safety. It prevents the circulation of substandard latex, ensures consistent industrial performance, protects end-users, and supports regulatory compliance in manufacturing and commercial applications.

What is BIS Certified for Styrene-Butadiene Rubber Latex

The BIS certified specification for Styrene-Butadiene Rubber Latex defines requirements for solids content, viscosity, pH value, mechanical stability, and performance characteristics. It also prescribes testing methods, storage conditions, and quality control parameters to ensure uniformity, reliability, and suitability for industrial use.
