Butyl type (photovoltaic) edge sealing tape

Butyl type (photovoltaic)edge sealing tape is a sealing tape made of butyl rubber as raw material andadded with modified substances such as polyisobutylene.

Butylsealant is an internationally recognized polymer material with the bestair-tightness and water-tightness. It has three major properties: low watervapor transmission rate, high adhesion, and electrical insulation. It also hasgood chemical stability and thermal stability. It can effectively help thecomponents resist water vapor and bond well with the glass, and is of greatsignificance for delaying the power attenuation of the components and improvingthe power generation efficiency throughout the life cycle.
