Before the 1990s, China's pressure-sensitive adhesives were mainly emulsion-type acrylate pressure-sensitive adhesives. The technology was basically introduced. In the past decade, there has been no significant development in emulsion pressure-sensitive adhesives.
After the 1990s, solvent-based acrylate pressure sensitive adhesives began to enter the market for double-sided tapes, protective tapes and labels. Its technology is mainly from research institutions in Taiwan, Japan and China. Most of the formulations, whether introduced or self-developed, are diplomatically linked. Pressure-sensitive adhesive tape Solvent-based rubber pressure-sensitive adhesive is mainly used in the manufacture of PVC electrical tape. Its formula is based on natural rubber and styrene-butadiene rubber. It has not changed much.
At present, some powerful tape manufacturers have established their own research institutions, and began research on high solid content pressure sensitive adhesives, hot melt pressure sensitive adhesives and radiation curing pressure sensitive adhesives to meet environmental protection requirements, save energy and reduce costs.
