1. Introduction of Economical Backsheet BPV 300E |
Solar back sheet is one of the key encapsulation materials which are applied in the PV module, composed of the fluorine materials with excellent climate durability. No fluorine-contained back sheets are laminated by multilayers of PET by adhesives.
2.Specification of Economical Backsheet BPV 300E |
Good overall physical performance, water, oxygen block performance, dielectric weather aging resistance. Suitable for all kinds of laminating process. It can make the solar panels to be used more than 25 years in floor, roof, gobi, desert, coastal areas.
Item | Unit | Value |
Thickness | mm | 320~340 |
Peel strength among layers | N/cm | ≥4 |
Breakdown voltage | KV | ≥18 |
Partial discharge | V | ≥1000 |
Water vapor transmission | g/㎡·day | ≤1.5 |
3. Application of Economical Backsheet BPV 300E |
PV products are widely used in many industries. Back sheet is the critical factor to ensure its 25-year working-life. The solar module back sheet is on the surface of the PV module. After bonding with EVA, it can block the air to make a vacuum seal for the core region of the module. In order to ensure that, the primary task of the seal is to be water-proof, air-proof and electricity-proof. So the solar module back sheet should bear the properties of high electrical insulation, high weathering resistance, high adhesion and low water vapor permeability.
