Are you struggling to decide which PVB Interlayer Film can truly meet your project’s safety, energy, and performance requirements? Many buyers face the same problem. If you choose the wrong product, you risk poor durability, weak bonding, or unnecessary costs. That’s why it’s important to know exactly what to evaluate before making a purchase.
PVB Interlayer Film is more than just a material placed between glass sheets. Made from polyvinyl butyral resin with plasticisers and additives, it provides adhesive strength, light transmittance, resistance to heat and cold, and high elasticity. In architectural and industrial glass applications, it plays a vital role in safety, performance, and comfort.
For buyers, this means every procurement decision affects not only the quality of laminated glass but also the success of your projects.
1. Penetration Resistance and Safety
One of the most critical features of PVB Interlayer Film is its ability to keep glass fragments together when impacted. When hard objects strike laminated glass, the interlayer prevents penetration and holds the glass pieces in place. This ensures that broken glass will not injure people. If your project involves building facades, automotive glass, or public facilities, penetration resistance should be your top priority.
2. Energy Saving and Heat Insulation
Energy performance is another important factor. Laminated glass made with PVB Interlayer Film can block infrared rays, reducing heat transfer and improving insulation. This leads to energy savings in buildings by lowering air conditioning and heating costs. High visible light transmittance (VLT) can also be adjusted by changing the ratio of nano heat insulation media, giving you more flexibility. For buyers, this means balancing energy efficiency with transparency requirements.
3. Security Function for High-Risk Applications
If you need bulletproof or high-security glass, PVB Interlayer Film is the right choice. Its excellent adhesive performance ensures a firm bond between glass and interlayer, making it difficult to separate or break through. For banks, airports, and government buildings, this feature can be a deciding factor when evaluating suppliers.
