Production process flow:

Raw material preparation and mixing: the polymer materials such as polyether ether ketone (PEEK) are evenly mixed with the necessary additives to prepare the basic raw materials required for the production of SGP film.

Extension molding: the mixed raw materials are molded, and the thickness and uniformity of the patented extension system is used to control the film, solving the problem of mucosa and stripping in the traditional process.

Low temperature plasticizing and cooling: plasticizing through the low temperature flow extension system to prevent the aging caused by high temperature under the condition of ensuring the material performance, and then cool the film.

Online stress removal treatment: the online stress removal device is integrated in the production line to eliminate the internal stress generated by the film during the cooling process, and improve the stability and service life of the finished product.

Rolling and cutting: The cooled SGP film is rolled uniformly under the action of the tension control system and cut into specific sizes according to customer needs.

Quality inspection and packaging: the finished product thickness, transparency, tensile strength and other indicators to ensure that the quality of the film meets the standards, and then packaging and shipment.

 

Advantages of SGP film production line equipment:

  1. Automatic weighing type metering device to ensure a variety of solid and liquid additives and raw material high-precision feeding. SGP belongs to the ionic type middle layer consisting of an ethylene-methacrylic acid copolymer with a small amount of metal salts.
  2. The low-temperature flow extension system ensures the good performance of the film under the condition of full mixing and plasticizing.
  3. The special design of the extension part solves the problem of mucosa and stripping.
  4. Unique online tempering and stress removal device.
  5. Multiple tension control systems in the production line can smoothly transfer the elastic sheet in the process of cooling, traction and rewinding.
  6. Siemens PLC and industrial control machine are under centralized control, which can easily realize closed-loop control.

 

Advantages of the SGP film:

1, high transparency: the light transmittance of SGP film is up to 90%, you can clearly see the protected object, and will not affect its original color and luster.

2, excellent weather resistance and chemical resistance: SGP film has good weather resistance and ultraviolet resistance, not easy to aging and discoloration; and it is also chemical resistance, not easy to corrosion, long-term stable performance.

3, scratch-resistant: SGP film has a certain hardness and scratch-resistant performance, which can effectively protect the patch from scratches and wear.

4, good processing: SGP film has good flexibility and processing, easy to bend and paste, suitable for a variety of different shapes and sizes of the paste.

5, safety and environmental protection: SGP film does not contain harmful substances, safe and environmental protection, can be recycled.

 

Main Application:

  1. Excellent safety and impact resistance

High strength impact resistance: SGP film compared with the traditional PVB film, has higher impact resistance. It can effectively enhance the strength of the glass, and when the glass breaks, the SGP film can better maintain the adhesion of the fragments, reducing the risk of splash and injury.

Explosion-proof and bulletproof function: SGP film because of its excellent structural performance, in the application of explosion-proof glass and bulletproof glass is particularly prominent. It can withstand stronger impact and pressure, and is widely used in safe places, such as government buildings, banks, military facilities, etc.

  1. Excellent transparency and optical properties

Highly transparent: SGP film has very good optical transparency and can provide a clear vision, especially for high-end buildings and automotive glass. It does not affect the light transmittance and visual effect of the glass, maintaining a high-quality visual experience.

Lower color difference and optical distortion: Compared with the traditional PVB film, SGP film has more stable optical performance, lower color difference and distortion, which is suitable for the application scenarios with strict visual effect requirements.

  1. Excellent resistance to moisture permeability

Lower water vapor permeability: SGP film is superior to traditional PVB film in water vapor resistance. It can effectively prevent the penetration of water vapor and moisture, prevent the accumulation of water inside the glass, to avoid long-term use of glass haze spots, haze or corrosion phenomenon.

Improve glass durability: Due to its excellent water vapor protection performance, SGP film can improve the long-term stability of glass and prolong the service life of glass products.

  1. Improved mechanical strength and durability

Strong weather resistance: SGP film can withstand more extreme temperature changes, humidity fluctuations and other harsh environmental conditions, and keep its performance unchanged. It is more resistant to aging than the traditional PVB film, anti-oxidation, adapt to long-term outdoor environment applications, and maintain the stability of glass performance.

Enhance durability: SGP film has a strong durability, can prolong the service life of glass products, especially when used in harsh environment, can maintain its original strength and stability.

  1. Excellent sound insulation performance

Excellent sound insulation effect: SGP film has good sound insulation performance, widely used in the glass applications that need sound insulation effect. It can effectively reduce the transmission of external noise, improve user comfort. For example, SGP film is an ideal choice in urban tall buildings, airports, railway stations and other places requiring sound insulation.

  1. Low deformation and stress

Reduce glass stress: due to the characteristics of SGP film, it can effectively reduce the stress concentration on the glass surface, prevent the glass deformation or cracking due to pressure changes, so as to improve the strength and stability of the glass.

Improve the structural stability of glass: SGP film can provide better structural support for glass and prevent glass from deformation or rupture under the action of external forces.
