●LBA (LBAA)
LBA has high conductivity using special conductive carbon black, and it is made up of a closed cell structure. Carbon is completely compounded with polyethylene so that it neither crumble nor bonds, and can be extensively used for wrapping materials of various IC products.
●LBRA (LBRAA)
LBRA is more flexible than LBA and suited for use as wrapping or cushioning material for products that require static protection. The foaming agent is nitrogen gas and will not contaminate precision measuring equipment.
* Adhesives are not conductive.
