A global scientific company active in the fields of health, nutrition and materials. Royal Dutch DSM Group, its High-temperature material family Add new members -Arnitel ® HT TPC , will be high temperature TPC Long-term work problems raised to 175°C , peak temperature increased to 190°C . DSM Utilization Arnitel ® HT TPC Material solutions help automotive manufacturers create innovative, integrated, flexible heat-pressurized tubes to achieve one-step molding of the production process, which not only greatly increases production efficiency, but also reduces production costs by approximately 50%Weight loss 40%At the same time, the risk of deformation, leakage and detachment of the heat pressurizing tube during engine operation is greatly reduced, which brings a new standard of flexible supercharged hot air intake tube to the automotive industry.
Nowadays, in order to achieve higher energy efficiency in the automotive industry, the requirements for engine systems are becoming increasingly demanding, especially with respect to the temperature resistance, pressure resistance and stability of the pressurized intake manifold. This presents new challenges. Most of the manufacturing processes use three-section assembly structure, that is, the assembly of rubber parts and engineering plastics (or metal) parts with metal joints, not only the production process is complicated, the production cost is high, there are also risks such as easy deformation, easy leakage, and easy disengagement. The service life is also difficult to guarantee.
As a leading supplier of innovative material solutions, DSM helps the automotive industry to create innovative, one-piece flexibilities through long-term close cooperation with automotive manufacturers, as well as professional experience in materials and structural design based on R&D and technical teams. Heat pressurization tube. The heat pressurization tube uses Arnitel® HT TPC (thermoplastic elastomer) in DSM's high temperature resistant material family to realize the one-step molding of the production process and the integration of the part structure, which not only greatly improves the production efficiency, but also improves the production efficiency. The production cost can be reduced by about 50% and the weight loss can be up to 40%. At the same time, the risk of deformation, leakage and detachment of the heat pressurizing tube during engine operation is greatly reduced.
The heat booster tube needs to withstand high temperature environment for a long time, and the engine and intercooler (fixed on the car chassis) connected to both ends of the heat booster tube will continuously generate relative motion during driving of the vehicle, and the heat booster tube must also be considered. Assemblability, therefore, requires the application of materials with both high temperature resistance and flexibility. Although the three-section structure made of rubber and engineering plastics can meet the above requirements, due to the relatively poor mechanical thermal properties of rubber, The larger wall thickness can meet the requirements of the hot charge air tube, so the weight of the assembly is large. In addition, the thermosetting rubber cannot be recycled, thus greatly reducing the environmental friendliness of the assembly.
However, ordinary thermoplastic elastomers obviously cannot meet the stringent requirements of heat-pressurized tubes for temperature resistance of materials. As the inventor of Diablo high-temperature technology, DSM has more than 25 years of professional experience in air intake system materials. , Successfully invented Arnitel® HT TPC High Temperature Thermoplastic Elastomer, redefining the temperature resistance standard of thermoplastic elastomer, and increasing the long-term operating temperature of the heat-resistant TPC from 150°C to 175°C. Meanwhile, Arnitel® HT TPC The heat aging performance has also been greatly improved, and has excellent high temperature oil resistance. Not only that, Arnitel® HT TPC is a thermoplastic material, so the material can be recycled after the components are recycled.
DSM's technicians also helped the customer to improve the silencer structure of the turbocharger outlet port, thus avoiding the additional radiation noise due to the use of TPC materials, and fully taking into account the passenger comfort requirements.
In the case of pressurized cold tubes, DSM offers Akulon® PA6 and Arnitel® grades of ordinary grades. Through blow molding and injection molding processes, DSM can achieve the conversion of supercharged cold tubes to plastic steel.
