Polyvinyl Butyral Manufacturer

In recent years, with the accelerated pace of urbanization in my country and the continuous growth of automobile sales, there has been a strong demand for PVB laminated glass. At the same time, with the development of technology, Polyvinyl Butyral Resin (PVB) Film has been researched and developed, and the application market has been further developed. In this development process, we must not only pay attention to new technological innovation, but also overcome the technical difficulties in the process of PVB waste collection and recycling, so as to achieve the environmental friendliness and maximize the economic benefits of the PVB industry. At present, the recycling of PVB resin mainly includes physical recycling method, chemical recycling method and energy recovery method.     Physical recycling is to put the discarded PVB through a series of physical treatment processes, such as separation, purification, cleaning, etc., and at the same time, add certain additives as required for reuse. This method can effectively utilize PVB materials and greatly reduce environmental pollution. For example, the PVB solid waste and scraps discarded in the market are recycled, and after sorting, cleaning, drying, and crushing processes, plasticizers, tougheners, three-salt stabilizers and other additives are added, and waterproof membranes for construction are produced through high-speed mixing, mastication, tableting and other processes. Through experimental research, it has been found that the waterproof membrane has good mechanical properties, convenient processing, and a wide operating temperature range, and has broad market prospects in the construction field.   The chemical recycling method uses light, heat, radiation, and chemical reagents to degrade PVB polymer into low-molecular single or hydrocarbon substances. At the same time, the cracked raw materials can be reused. Common cracking methods include hydrolysis, alcoholysis, thermal cracking, hydrocracking, catalytic cracking, etc. However, the current technology of this deep chemical recovery method is not very mature, the technology cost is high, and the economic benefits are low. Currently, the most commonly used method is to process waste PVB to obtain pure polymer resins and additives. Supercritical separation technology is used to separate the additives and resin in colorless PVB.   Energy recovery is the process of extracting energy from waste plastic, typically used as fuel or to generate steam to generate electricity. Because PVB (PVB SD-4 & PVB B-03HX) polymer contains a large amount of hydrocarbons, it is flammable. Although the energy recovery method is one of the methods for recycling PVB waste, it is not commonly used due to its high cost.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com

Polyvinyl Butyral (PVB) is a versatile and widely-used thermoplastic resin known for its exceptional properties. It is made by the condensation polymerization of polyvinyl alcohol (PVA) with butyraldehyde. PVB offers unique advantages such as transparency, excellent adhesion, impact resistance, and UV stability, making it indispensable in numerous industries.   One of the key characteristics of PVB is its high transparency. PVB films have excellent optical clarity, allowing light to pass through without distortion. This property makes PVB a popular choice for safety glass applications, such as laminated glass used in automotive windshields and architectural windows. The inherent toughness of PVB also enhances the safety of laminated glass by preventing it from shattering upon impact.   PVB exhibits remarkable adhesion to various substrates, including glass, metals, and plastics. This adhesive property makes it an ideal interlayer material for laminated safety glass. The strong bond created by PVB interlayers holds the glass together even when it breaks, thus providing enhanced protection against personal injury and property damage. The adhesion of PVB also makes it suitable for laminating other materials, such as textiles, metals, and electronic components.   When used as an interlayer in laminated glass, PVB significantly improves impact resistance. The tough and flexible nature of PVB helps absorb and distribute energy upon impact, minimizing the risk of breakage. This impact-resistant property finds applications in safety glass for automotive windshields, architectural structures, and bullet-resistant glass.   PVB exhibits excellent resistance to ultraviolet (UV) radiation. It acts as a UV stabilizer, protecting the underlying materials from degradation caused by prolonged exposure to sunlight. This makes PVB an ideal choice for outdoor applications, such as solar panels and architectural glazing, where UV resistance is crucial.   PVB (PVB SD-5 & PVB B-04HX) can be customized and modified to suit specific application requirements. By altering the molecular weight and modifying the plasticizers, various grades of PVB with different characteristics can be produced. This versatility enables manufacturers to tailor PVB properties such as viscosity, glass transition temperature, and adhesion strength to meet the specific needs of different industries, including automotive, construction, and electronics.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com
