Bulk products from china Stronger Adhesion strength eva film tpu high elastic film for glass

Product Overview

Description

 

EVA film for glass lamination:

A thermosetting adhesive of EVA film for laminated glass on the folder in the middle (EVA is Polyethylene vinylacetate, polyethylene - referred to as the polyvinyl acetate copolymer). Since the EVA film in adhesion, durability, optical characteristics have advantages, such that it is more and more widely used in current components and a variety of optical products.

Product advantages(EVA film):

1, high transparency, high adhesion can be applied to a variety of interfaces, including glass, metal and plastics such as PET.

2, good durability can resist high temperatures, moisture, UV and so on.

3, easy to store. Stored at room temperature, EVA adhesion unaffected by moisture and water absorption of the film.

4, compared to a stronger effect of noise PVB, especially high frequency sound.

5, low melting point, easy flow, technology can be applied to a variety of laminated glass, such as patterned glass, tempered glass, curved glass and so on.

Performance(EVA film):

EVA film used to make laminated glass, laminated glass full compliance with national standards of "GB9962-99", below to 0.38mm thick transparent film, for example, the performance indicators are as follows:

Item Index

Tensile strength (MPa) ≥17 visible light transmittance (%) ≥87 Elongation at break (%) ≥650 mist rate (%) 0.6

Adhesion strength (kg / cm) ≥2 radiation resistance Qualified Water absorption (%) ≤0.15

Heat resistance, moisture resistance Qualified Qualified Qualified Shot bag impact resistance, impact resistance UV cutoff qualified rate of 98.5%.

Production equipment(EVA film):

Will make a good glass placed in a vacuum bag vacuum, vacuum degree ≥700mmHg (0.092Mpa), a temperature of 100-110 ℃ (the actual temperature of the glass surface), incubated for 10 minutes, cooled to below 60 ℃, unloading vacuum.

Because the material properties of the reasons EVA, EVA molding process when there is a very high demand. According to its solar battery age and aging demanding, many domestic manufacturers through constant trial and error, finally we made significant progress in terms of the formulation. While most of the domestic EVA film has reached the international advanced level (the indicators are in line with the requirements, some indicators over foreign products).

Due to the demanding requirements of photovoltaic industry, the production of EVA equipment requirements are very high. Stability of the equipment, and shrinkage control, to minimize the impact of the loss of its formulation ingredients and the like. Domestic equipment manufacturers do have a lot of film, but are more or less below standard. EVA led many manufacturers to choose their own assembly or assembly equipment. Until in 2010, with the whole domestic EVA film production line, the company (Suzhou Jin Weier Machinery Co., Ltd.). China's pace of development on EVA industry faster. EVA film to reduce the cost, the cost of reducing indirect photovoltaic industry.

Storage conditions(EVA Film):

When placing them in storage Do not remove the original packaging, in dark airy place and with temperatures not exceeding 30 ℃, humidity less than 80%.

Product Specifications(EVA film):

Thickness: 0.25mm, 0.38mm width: 2.1m 6, the product color variety (transparent, opaque and colored), to choose from.

EVA now more applications in the field of solar PV, thin-film photovoltaic modules as a package to use.

Terms and Conditions(EVA film):

1, curing conditions: fast curing film, heated to 135 ~ 140 ℃, constant temperature 15 ~ 20min; conventional-type film, and heated to 145 ℃, constant temperature 30min.

2, light transmittance: greater than 90%.

3, the degree of crosslinking: Fast-curing film is greater than 70%, greater than 75% of conventional type film.

4, the peeling strength: glass / film is greater than 30N / cm, TPT / film is greater than 20N / cm.

5, temperature resistance: high-temperature 85 ℃, low temperature -40 ℃, no thermal expansion and contraction, good dimensional stability.

6, UV resistant aging properties: Prolonged UV exposure no cracks, no aging.

Precautions(EVA Film):

During use, pay attention to moisture and dust, avoid contact with colored objects; do not roll off the packaging of the whole film is exposed to air; cut into slices of film if they can not run the same day, they cover close . EVA film if moisture absorption, it will affect and glass adhesion; if vacuuming, will affect the light transmittance; and if colored, unclean objects come into contact, due to the strong adsorption capacity of EVA film, likely to be contaminated.     

EVA film

product Description

EVA film Introduction:

Utilize E.V.A. Film makes possible adhesion at low temperature,facilitating system operation,it can produce the products which is same by using autoclaces

It can produce the laminated glass,which could be used for building,fitment,industrial uses etc and also can produce various function glass,such as burglarproof glass etc,can be by produced by means of CXJ Vacuum heating laminating machine

Glass can be laminated with a patterned cloth,papar,printed polyester,so the glass with a wide variety of decorative uses can manufactured.

EVA film Characteristics

None absorb moisture,water absorption is lower than 1%,can be preserved in normal temperature and humidity.

The cost is lower than PVB ,can apply with low temperature and low pressure,lower prounction cost and less investment

Not including plasticizer,high agglutinate performance to plastic,metal sheet,paper etc

Short production cycle

Complied with national standard of GB9962-99.
