Innovative PVB Film Extrusion Production Line Revolutionizes PVB Safety Glass

GWELL, as an industry-leading supplier of PVB film extrusion production lines, has launched an advanced Polyvinyl Butyral (PVB) film extrusion production line. This specialized equipment system produces high-quality PVB films, which are key materials in manufacturing PVB safety glass. Widely used in the automotive and construction industries, PVB films are essential for producing PVB laminated glass with exceptional safety and optical performance.

Main Production Processes

Raw Material Preparation

PVB resin is mixed with plasticizers, stabilizers, and other additives in specific proportions to form a uniform PVB mixture.

Raw Material Drying

Due to the moisture sensitivity of PVB materials, the PVB mixture is dried before extrusion to reduce water content, prevent bubble formation, and ensure the quality of the PVB film.

Extrusion and Plasticization

The dried PVB material is fed into a high-performance twin-screw extruder provided by GWELL. Under heat and shear forces, it melts and plasticizes into a uniform PVB melt.

Filtration

The molten PVB material passes through an advanced filtration system to remove impurities and unmelted particles, ensuring the purity and quality of the PVB film.

Mold Shaping

The PVB melt is extruded through a precisely designed flat die from GWELL, forming the initial shape of the PVB film.

Cooling and Setting

Using cooling devices such as chill rolls or water baths, the PVB film is gradually cooled and set to prevent wrinkles and dimensional changes.

Traction and Winding

The set PVB film is pulled out by a high-precision traction device and neatly wound onto a winder for easy storage and subsequent processing.

Main Equipment Components

GWELL Twin-Screw Extruder

Renowned for its excellent mixing and plasticizing capabilities, suitable for processing PVB materials.

Metering Feeding System

Product Features and Advantages of PVB Film

Excellent Adhesion Performance

PVB film has strong bonding capabilities, securely laminating two pieces of glass to form PVB laminated glass.

High Transparency and Optical Properties

Providing clear visibility and meeting optical-grade requirements, PVB film is an ideal material for PVB safety glass.

Safety Features

In the event of glass breakage, PVB film adheres to fragments, preventing them from scattering and offering safety protection.

Weather Resistance and UV Protection

PVB film maintains stable performance under prolonged exposure to sunlight without aging, extending the service life of PVB laminated glass.

Applications of PVB Film

Automotive Industry

Used in the manufacture of automotive windshields and other PVB safety glass components, PVB film enhances vehicle safety.

Construction Industry

PVB film is suitable for producing PVB laminated glass in buildings, such as curtain walls, skylights, and soundproof barriers, improving building safety.

Photovoltaic Industry

As an encapsulation material for photovoltaic modules, PVB film protects solar cells, enhances durability, and improves energy conversion efficiency.

Other Fields

Applied in bulletproof glass, aerospace equipment, and other areas requiring high safety performance, PVB film elevates product safety levels.
