In the 1990 of the 20th century, pressure-sensitive adhesive emulsion acrylate pressure-sensitive adhesive technology is basically the introduction of nearly ten years, emulsion pressure-sensitive adhesive with no significant developments.
After the 90 's, solvent based acrylic pressure-sensitive adhesives have come into the market for the production of double-sided tape, masking tape and label. Its technologies mainly come from Taiwan, Japan and mainland China's research institutions. Neither introduced nor the self-developed recipes, most of which are foreign-linked. PSA solvent rubber based pressure sensitive adhesive for PVC electrical tape production, its formula based on natural rubber and styrene-butadiene rubber elastomer and there has been no big change.
There are some strengths of suppliers have established their own research institutions, high solid content from the start pressure-sensitive adhesives, hot-melt pressure-sensitive adhesive and study radiation-curable pressure sensitive adhesives to meet environmental protection requirements, save energy and reduce costs.
