Features :
1) It is difficult to turn yellow and is durable for over 20 years.
2) This EVA film is used as the laminate material for producing safety glass because of its strong adhesion. Once the glass breaks, it can stick to the glass fragments and stop the danger.
3) It is sufficient to store this product at a room temperature. The adhesion of EVA film would not be affected by humidity.
4) This extra clear EVA film is praised for its high transparency because its light transmittance is over 90.5%. Thus, when applying it in the window glass, it will not influence the indoor sunlight. In the meantime, it can block over 99% ultraviolet rays.
Production processing:Our diverse EVA interlayer film product line is custom engineered to offer precision extrusions for a variety of glass lamination applications,are unmatched in optical clarity, hot and cold characteristics and offer the best overall quality in the glass lamination industry.
EVA Interlayer Film is custom engineered from copolymer resin and is used as an interlayer sandwiched between two pieces of glass or plastic sheet. EVA interlayer film is ideal for use in smart glass applications like privacy for conference rooms.

Applications:
To ensure quality, we use digital camera inspection on all interlayer film production. Computerized systems can detect and document pin holes, voids, gels, wrinkles, streaks and dark or light contaminants as small as 0.3 mm. All of our interlayer extruders are housed in an atmospherically controlled hard walled white room. Each extrusion line is in its own ISO Class 7, soft walled clean room. Engineers know that the highest quality standards are found in the aerospace industry. This is why the vast majority of all TPU bonded aircraft canopies and windows are laminated using Argotec interlayer film. Our products do not require refrigerated storage and do not contain plasticizers that can migrate and degrade a composite structure. SWM has the cleanest, most modern interlayer film extrusion operation in North America, Europe and Asia and extrudes over 50% of the world's total usage of TPU interlayers. Our Argotec film products, available in aliphatic TPU and EVA resins, are the highest quality in the industry.
