Global scientific company active in the fields of health, nutrition and materials The Royal Dutch DSM Group , In response to new challenges in the temperature and flame retardance of materials in the automotive electronics industry, new Arnite® hydrolysis-resistant PBT The product portfolio provides powerful material support for the new development of the automotive industry.
With the maturation of new energy vehicles and autonomous driving technologies, the demand for automotive electronic materials is increasing day by day, and the requirements are becoming increasingly stringent. For example, traditional automotive electronic materials are basically free of flame retardant requirements, and are used in new energy vehicles. Electronic materials are required to achieve a flame retardant level. This presents a problem for vehicle manufacturers, automotive electronics component manufacturers, and material suppliers.
In addition, both new energy vehicles and driverless cars use more electronic components than conventional cars, and the heat dissipation is also greater. The continuous operating time and the peak temperature of the engine environment continue to rise, and thus the temperature resistance of the materials is also raised. High demand.
In the past, materials used in the automotive electronics industry included Nylon 6, Nylon Double 6, and Common PBT materials. However, in the face of new challenges in the automotive electronics industry, these materials have failed.
In order to meet the more stringent requirements of the market for automotive electronic materials, the Royal Dutch DSM Group developed a new Arnite® hydrolysis-resistant PBT with a 30% glass-reinforced formulation, which makes the material still excellent at 150°C. Performance. In addition, Arnite® hydrolysis-resistant PBT series also includes flame-retardant grades to achieve a UL94 V0 flame-retardant rating of 0.4 mm, which fully meets new requirements for automotive electronic components such as automotive connectors, control equipment and sensors. .
Although PBT has long been one of the common materials in the automotive electronics industry, its inherent water-decomposability has greatly limited its scope of application. Not only that, customers also need to apply very stringent materials when performing PBT injection molding. The rigorous drying operation ensures the quality and performance of the injection molded parts. The new Arnite® hydrolysis-resistant PBT products are superior to other PBTs in many respects, but its most significant advantages are: In the USCAR standard 3, 4, 5 type temperature In the humidity environment and double 85 damp heat cycle test (85°C and 85% relative humidity), its mechanical properties have good retention for up to 3,000 hours.
Ms. Zhan Hong, product manager of DSM Greater China, introduced: “Arnite® hydrolysis-resistant PBT fills this short board of PBT water decomposition, so that it can also meet the temperature resistance, moisture resistance and resistance of automotive electronics industry. Combustion requirements. At the same time, our products are superior to almost all similar products in terms of fluidity and crystallization speed, saving cycle time and maintaining good mechanical properties throughout the life cycle of electronic components.
The Arnite® hydrolysis-resistant PBT family continues to add new members, including different levels of glass-reinforced grades, impact-modified grades, and product grades with better silicone sealant adhesion to meet a variety of automotive electronic components. Different requirements for materials under operating conditions, and to meet future higher strength testing and validation standards.
In addition, in automotive electronics applications, DSM also offers higher temperature resistant grades such as Stanyl® PA46 and ForTii® PA4T and other high-performance, high-temperature resistant polyamides, making DSM a global leader in automotive electronics Application of one of the plastic suppliers that offers a comprehensive product service portfolio.
