Intrusion resistant safety glazings and solar cell modules

摘要

Described certain plasticized poly(vinyl butyral) (PVB) interlayer sheets that may be used to produce safety glass and solar cell laminates having enhanced penetration resistance and adequate adhesion levels. In particular, the stress value of these interlayer sheets at an elongation of 120% is preferably in the range of from about 8 to about 15 N/mm².
