EVA interlayer film

Willing® EVA interlayer summary

Willing® EVA film Introduction

Jiaxing Willing Lamiglass Material GmbH (W.M.C) has rich experiences of 8 years to produce EVA film for laminated glass both for industrial applications of exterior and interior. The factory has 5,200 square meters and own two EVA automatic production line, the product with superior quality for glass industry and processing.

We produced EVA film for applications of glass laminating processing and solar panel, mainly for architectural laminated glass which has more excellent performances like safety, Security, acoustic insulation, energy saving, chromatics and creations. Aesthetics can be fully applied in field of architecture.

ArchitexTM EVA film - Raw Material

EEthylene vinyl acetate (also known as EVA) is the copolymer of ethylene and vinyl acetate. The weight percent vinyl acetate usually varies from 10% to 40%, with the remainder being ethylene.

It is a polymer that approaches elastomeric materials in softness and flexibility, yet can be processed like otherthermoplastics. The material has good clarity and gloss,

low-temperature toughness, stress-crack resistance, hot-meltadhesive waterproof properties, and resistance to UV radiation. EVA has a distinctive "vinegar" odor and is competitive with rubber and vinyl products in many electrical applications.

Willing® EVA Film advantages

WMC GLASS is at the forefront of continuous innovations in the development and manufacture of all processes productive thanks to technology that gives us the optimization of the resources of our customers. Working for companies that give a absolute priority to R & D and are always interested in new technologies production.

WMC GLASS has devised to create infinite kinds EVA film for different applications such as construction projects,EVA film laminated glass can be installed interior and exterior places that its laminated glass own high transparency and brightness; Colored EVA film almost used for interior decoration of window, kitchen, furniture, entertainment venues, also colored transparent/translucent and opaque EVA film for private space like office partition, meeting room, hallway and shower room; for special lamination with other material insertions can choose our functional EVA film.

High quality EVA interlayer is processing in laminating glass with high transmittance and durable adhesion with different laminates. Different application request its temperature depends on insertion material and specific operation. Generally speaking Willing company can provide suitable EVA film with different melting points can be bond with different material in laminating processing. Universal EVA film transmittance can reached over than 90% with clear float glass after laminating, if you need a higher rate of transmittance please use Willing company high/Ultra transparency EVA film which can be up to 92% transmittance rate; Willing®EVA Film has good bonding with many kinds material not only glass but also Acrylic, PET, PETG, PVC, PC, Fabrics, Silk, metal,plywood, solar panel and specimens, are undergoing change and deformation at high temperatures, Willing ®EVA film allows working at low temperatures such so that the laminated glass inserts did not suffer any alteration. Deco-Laminated glass with Willing®EVA film will be your private custom interior items, and its an really exclusive artwork.

Today, glass decoration has become an integral part of interior decoration, Willing®EVA film owns superior quality with glass as perfect interpretation of its excellent safety and color. If glass was shattered by external accidents, broken glass like a spiderweb to be bonded on EVA film that can avoid injury. The color film is unparalleled, color scheme gives the aesthetic visual experience.Willing®EVA film can be used for architectural laminated glass including exterior, interior, decorative safety glass applications.

Willing® EVA film in laminated glass processing

EVA interlayer film in laminated glass processing

  • Laminating glass(LG), one layer(e.g 0.38mm EVA ) film with the float glass sheets.
  • Take LG into silicone bag to pre-vacuum for 5-10mins.
  • Put LG into the furnace (EVA laminating machine), start to heat up to 120℃ (120℃ means actual temperature of glass surface).
  • Keeping temperature (120℃) for 30mins (5mm glass+0.38 film+5mm glass), theoretically, total thickness increase 5mm, heating time should longer than 8 min accordingly.
  • Cooling down to 60℃, stop vacuum.
  • Open the furnace, take out the LG.

Kindly Attentio

  • Pre-vacuum and heating holding time needed to fine adjust according to glass thickness, operating room temperature.
  • From enter into furnace to cool down to 60℃ that during above processing steps can not stop vacuum.
  • Holding timing should be start at 120℃

    • Example

kindly Reminder

  • Laminating Operation Guide only for laminating with WMC GLASS EVA film.
  • Only Ultra Clear (WMC-UTC series) temperature is higher 20°C than universal clear and all colors EVA film, specially adjust initial processing temperature in WMC-UTC series.
