Liquid Butadiene Styrene Rubber(LSBR)
LSBR is a low molecular weight copolymer of butadiene and styrene with a molecular weight of 2000-10000. It possesses excellent electrical insulation and physical properties, and is often used in many fields such as circuit boards, adhesives and sealing materials.
Compared with liquid polybutadiene (LPB), LSBR possesses a higher glass transition temperature and better heat and wear resistance. Replacing LPB with LSBR can improve the adhesive flow phenomenon during the processing of copper clad plates.
Packed in 50kg/drum, 170kg/drum, The storage period is 1 year.
Safety instructions:
Storage should be at cool, dry and ventilate. The best condition is among -20 ~ 38℃. Shelf life of 12 months, if expire, still used if up to standard through retest. When transportation should avoid rain, sunlight. Don’t mix with strong oxidizer.
