1. HK-H Solar EVA film
Huakai Solar EVA encapsulation film is a three-dimensional network structure formed by extrusion-casting of EVA resin (ethylene-vinyl acetate copolymer) and extrusion-casting of EVA encapsulation film under certain temperature and pressure. High-strength materials are used in solar cell modules.
More than 90% transmittance
Suitable degree of crosslinking
Good durability, UV resistance, heat resistance and humidity resistance
Great bonding strength with glass and back sheet materials
Low shrinkage in lamination
Product models and specifications
Lamination thermosetting process conditions
Equipment: Solar PV module laminating machine
1. Due to the difference in structural performance of the laminator, the process conditions used will not be the same.
2, the working environment temperature of the laminating machine (the difference between winter and summer) will cause different working temperature of the lamination.
3. The user must first make a sample to determine the correct lamination curing process conditions and ensure the quality of the mass-produced products.
The appearance quality of the product
1. Appearance: translucent, flat appearance, neat end face, no stains
2,Thickness: HK-H0.50GF thickness tolerance: ± 0.02MM
3. Width: HK-H0.50GF width tolerance: 2100+25/-0MM
4,Length: HK-H0.50GF tolerance of per roll : +1M/-0M
The product should be stored in a dry place indoors to avoid direct sunlight. The indoor temperature is controlled at 5 °C-30 °C, the corresponding humidity is less than 60%, and it should not be close to the heating equipment and dusty environment. The film can not be stacked to avoid causing adhesion.
Under the right storage conditions, the effective storage period is no more than 4 months from the date of production. Once the film is unpacked, the remaining film should be protected from dust, moisture, sun, and used up within one week.
Avoid sun, rain, fire, hard collision, free from pollution of the transportation environment and open storage. Do not let the product packaging damaged and stacking adhesion.
