- LSBR Liquid Styrene Butadiene Rubber
Product Description
LSBR/ Liquid styrene butadiene rubber is a low molecular weight copolymer of butadiene and styrene, with a molecular weight of 2000-10000. It has excellent electrical insulation and physical properties, and is often used in fields such as circuit boards, adhesives, and sealing materials.
Benefits & Features
Compared with liquid polybutadiene (LPB), LSBR has a higher glass transition temperature and better heat and wear resistance. Replacing LPB with LSBR in the processing of copper-clad laminates can improve the phenomenon of adhesive flow during the processing.
