Introduction
Synthetic rubber latex is an important industrial raw material in my country, mainly used in carpets, papermaking, textiles, printing, coatings and adhesives and other fields.
Carboxylated styrene-butadiene latex and carboxylated nitrile latex are currently the most widely used synthetic latex in China.
In order to meet the needs of different domestic latex users, GB/T 25260 is proposed to be composed of two parts.
--- Part 1.Carboxylated styrene-butadiene latex (XSBRL). The purpose is to provide a unified product for carboxylated styrene-butadiene latex stakeholders
quality technical basis.
--- Part 2.Carboxylated nitrile latex (XNBRL). The aim is to provide a unified product for carboxylated nitrile latex stakeholders
quality technical basis.
