BIS for Styrene-Butadiene Rubber (SBR) Latex (IS 11356: 2020)

Styrene-Butadiene Rubber Latex (SBR Latex) is widely used in paper coating, carpet backing, adhesives, construction chemicals, and textile applications due to its excellent bonding strength, flexibility, and chemical stability. To ensure consistent quality and safety, the Bureau of Indian Standards has defined the requirements under IS 11356:2020, which specifies the quality parameters for styrene-butadiene rubber latex manufactured, imported, or sold in India.

Compliance with BIS for Styrene-Butadiene Rubber Latex is mandatory under the applicable BIS QCO for Styrene-Butadiene Rubber Latex, making certification compulsory for manufacturers and importers. To supply the product in the Indian market, companies must obtain a valid BIS License for SBR Latex and follow the required testing and marking rules as per Indian Standards.
