1.Product Introduction
Ultra Clear EVA Film is made of modified plastic material by special processing. It has the advantages of no overflow at the edge, high toughness, high transparency, high bonding strength, high elongation and good low-temperature resistance. It is an ideal bonding material for laminated safety glass. This product is widely used in the compound of safety glass, such as guardrail, staircase handrails, sunlight room and so on.
| Product name | Thickness(mm) | Width(mm) | Length(m) | Scope of application |
| Ultra Clear EVA film | 0.38 | 500-2650 | 100 | Application: Curtain wall, sun room, top floor, stair handrail and other tempered glass lamination (suitable for relatively flat tempered glass) Difference "GS*TH" difference, the amount of glue overflow around the glass is small, the glass is easy to clean, the finished glass has a smaller haze and better clarity. Also suitable for colored mirror lamination to reduce the risk of edge oxidation |

3.Processing Technic
Note: After combining the glass, cold pumping10 mins.
1)Taking glass temperature as the criterion, and the temperature of high temperature period can’t less than 130℃.
2)Increase keeping time if glass thicknessincreased or SQM increased.
4.Application Cases
5.Packaging and transportation
precautions
1) EVA laminated glass adhesive film is usually required to be stored in a ventilated, dry, and clean warehouse, avoiding direct radiation from light and heat sources; Prevent rain, heavy pressure, external impact, and scratches from hard objects; The temperature in the warehouse should not exceed 30 ℃, and the humidity should not exceed 60%; When there is a large inventory of film, a tray should be placed under the film to facilitate ventilation, heat dissipation, and moisture isolation. If the film is subjected to pressure, heat, or excessive moisture, it may exhibit varying degrees of self adhesion. If possible, please hang it for storage and avoid heavy pressure as much as possible. If the surface humidity of the adhesive film is too high, it will also affect the bonding strength between the adhesive film and glass or other adhesives, affecting normal use.
2)EVA laminated glass film is prohibited from being stored in the same warehouse as flammable and explosive materials; The remaining film after use must be repackaged with clean materials to prevent the weak static electricity carried by the film itself from adsorbing dust and contaminating the film, affecting normal use.
3) EVA laminated glass film has an “effective storage period” of ten months from its production. Customers with inventory turnover must perform a rolling operation of “storing new and using old”. If customers use film that has exceeded the storage period for production and processing, we are not responsible for the quality of their products. If the film purchased by the customer has not been used for a long time and the storage period has exceeded the “effective storage period”, regardless of whether there are inherent quality problems with the product, we will not process returns or exchanges.
6.Special Warning
Whether it is EVA film or intermediate materials (such as photo paper), due to improper storage, there will be “discharge” phenomenon in rainy and humid weather. Even if glass appears, there will still be a thin layer of water mist floating on the surface of the glass. If this “moisture” phenomenon is not ruled out, the bonding strength of tempered glass after processing and forming will be greatly affected. Therefore, customers are advised to avoid high humidity weather during production. Proper drying of materials and glass is beneficial for improving bonding strength.
