Polyvinyl Butyral Resin (PVB) is a solvent Resin synthesized by the acetal reaction of Polyvinyl Alcohol (PVA) and butyraldehyde in contact with coal.

Because Pvb Resin itself contains a lot of hydroxyl groups, it can bridge with some thermosetting resins to improve the properties of chemicals and film hardness.

Because PVB resin has the above excellent characteristics, it is widely used in adhesive safety glass intermediate film of automobile and building, rust cutting primer, baking paint, wood paint, printing ink, adhesive of electronic ceramics and printed circuit board, adhesive between metal and metal, between metal and plastic, modifier of hot-melt adhesive, iron dimension waterproof processing of textile, etc. A variety of new industrial applications are also continuously developed and applied.

The general characteristics of PVB are as follows:

The appearance of polyvinyl butyral (PVB) resin is white spherical porous particles or powder, and its specific gravity is 1:1; However, the filling density is only 0.20 ~ 0.35g/ml.

Thermal properties

The glass transfer temperature (TG) of polyvinyl butyral (PVB) resin ranges from 50 ℃ of low degree of recombination to 90 ℃ of high degree of recombination; The glass transfer temperature can also be adjusted by adding an appropriate amount of Plasticizer to reduce it below 10 ℃.

Mechanical properties

The coating of polyvinyl butyral (PVB) resin has good water resistance, water resistance and oil resistance (it is resistant to aliphatic, mineral, animal and vegetable oils, but not to sesame oil). PVB is widely used in printing inks and coatings because it contains high hydroxyl groups and has good dispersibility to pigments.

In addition, its chemical structure contains both hydrophobic acetal and acetic ACID groups and hydrophilic hydroxyl groups, so PVB has good adhesion to glass, metal, plastic, leather and wood.

Chemical reaction

Any chemical that can react with secondary alcohol will also react with PVB. Therefore, in many applications of PVB, it is often used with thermosetting resin to bridge and harden with the hydroxyl group of PVB, so as to achieve the characteristics of chemical resistance, solvent resistance and water resistance.

Of course, films with different characteristics (such as hardness, toughness, impact resistance, etc.) can be prepared according to different types of thermosetting resin and different mixing ratio with PVB.

  • Institutional Buildings: Schools, hospitals, and other institutional buildings often use aluminium window profiles for their maintenance-free characteristics and long service life. The profiles can be customized to provide optimal light transmission and ventilation.

  • For those seeking a more streamlined look, retractable screen doors use a roller system that hides the screen when not in use. These rollers are designed to be compact and efficient, offering a sleek, unobtrusive solution for homeowners.
  • For instance, let's consider the humble rib stitch pattern. Traditionally, it involves alternating knit and purl stitches to create a stretchy, elastic fabric often used for cuffs and edges. However, with a spirit of varf forjat, a knitter might decide to change the ratio of knit to purl stitches, perhaps using two knits followed by two purls instead of the usual one-to-one ratio. This simple adjustment can result in a different look and feel for the fabric, making it more unique and tailored to the maker's preferences.

  • The profile is bent with both hands, and the twisting strength is good, and it can be restored after loosening your hands. If the strength of the aluminium profile is not enough, it is easy to be deformed, which may result in unqualified wind pressure resistance level, the finished switch is not smooth, and the deformation amount is too large.

  • Moreover, the versatility of wrought iron allows for customization. Whether it's a traditional, ornate design for a heritage property or a sleek, modern look for contemporary architecture, the fence spear points can be tailored to suit the style and ambiance of the surroundings. They can be painted in various colors or left to develop a patina, adding a rustic charm to the fence.
  • One of the key benefits of large metal lockable storage boxes is their size and versatility. These boxes can accommodate a wide range of items, from small valuables like jewelry and important documents to larger items like firearms and sports equipment. The spacious interiors allow you to organize your belongings neatly and efficiently, making it easy to find what you need when you need it.
  • Moreover, the design possibilities with large metal door handles are virtually endless. From classic, ornate designs that evoke a sense of history to sleek, minimalist styles that embody contemporary aesthetics, each handle tells a unique story From classic, ornate designs that evoke a sense of history to sleek, minimalist styles that embody contemporary aesthetics, each handle tells a unique story From classic, ornate designs that evoke a sense of history to sleek, minimalist styles that embody contemporary aesthetics, each handle tells a unique story From classic, ornate designs that evoke a sense of history to sleek, minimalist styles that embody contemporary aesthetics, each handle tells a unique storylarge metal door handles. Some are adorned with intricate engravings, while others feature clean lines and geometric shapes, mirroring the design philosophy of the space they belong to.
  • The Main Wrought Iron Fence Components
  • Overall, cast iron fences are a timeless choice for homeowners who want a fence that is not only strong and secure but also adds a touch of elegance to their property. With their durability, strength, and intricate designs, cast iron fences have stood the test of time and continue to be a popular choice for those looking to enhance the beauty and security of their homes.
  • Moreover, steel key boxes are not just limited to residential use. They find extensive application in commercial settings, such as hotels, car rental agencies, and property management companies. In these environments, they streamline key management processes, reduce the chances of lost keys, and enhance overall security.

  • There are different types of track and wheel systems available for sliding doors, depending on the size and weight of the door, as well as the desired level of functionality. Some doors may have a single track with two wheels, while others may have multiple tracks and wheels for added stability and support. Additionally, there are options for adjustable tracks and wheels that allow for fine-tuning of the door's operation.
  • The primary function of heavy duty door rollers is to facilitate the smooth opening and closing of large, heavy doors. Equipped with sturdy materials like stainless steel or hardened iron, they can handle weights that would break conventional rollers. Their robust design not only ensures longevity but also minimizes the strain on the door frame, preventing potential damage over time.

  • Before diving into repairs, it’s important to understand how screen door rollers work. Typically, these rollers are small wheels located at the bottom of the screen door, allowing it to slide effortlessly along a track. If the rollers become misaligned, debris builds up, or they break, your screen door can become stuck or noisy during operation.


  • Next, rehang the door on the track. Use the level to ensure it's straight, as an uneven door can cause additional strain on the new rollers. Adjust the height of the rollers if needed, so the door glides effortlessly without scraping the frame.
  • In the realm of home and commercial door systems, the sliding door wheel has emerged as a revolutionary design, offering unparalleled convenience, safety, and durability. This innovative component is specifically engineered to enhance the functionality and aesthetic appeal of sliding doors, making them an increasingly popular choice for both residential and commercial applications.
  • The steel housing, typically made from high-grade carbon or alloy steel, provides an unparalleled level of strength and rigidity. It shields the internal components, particularly the roller, from external environmental factors such as dust, moisture, and extreme temperatures. The steel construction ensures that the sliding roller can withstand heavy loads, impact, and corrosion, making it ideal for use in harsh industrial environments.
