Rubber Cushion Pad High Durability Buffer Pad for Solar PV Module Hot Lamination Processing
MKCP-PV-G1 Rubber Cushion Pad is a professional high-performance buffer material specially developed for solar photovoltaic module lamination machines and hot pressing equipment. It serves as a critical consumable in the PV panel manufacturing process, providing effective surface protection and uniform pressure buffering throughout the entire high-temperature vacuum lamination procedure.
PV lamination is the core process that determines the quality, tightness and service life of solar modules. During production, vacuum exhausts internal air, high temperature melts EVA adhesive, and even pressure bonds glass, battery cells and backsheets tightly while eliminating residual bubbles. Our PV rubber cushion pads ensure balanced heat and pressure distribution, prevent module deformation, scratching and bubble defects, and greatly improve the yield and consistency of finished solar panels.
Product Advantages & Customization
- Seamless Wide Size: Maximum seamless width reaches 3200mm, suitable for large-size PV module lamination
- Multiple Grade Options: Four different grades with diversified temperature resistance, EVA resistance and service life to match different production processes
- Ultra-long Service Life: Highest grade supports over 6000 pressing cycles, greatly reducing replacement costs and downtime
