For welding of plastic parts were made by Ron Bloom para polyamide and two polyethylene terephthalate glycol compounds. These new materials optimized for applications under the hood, and mass production.
' They are able to meet the latest demands of users, such as higher engine compartment temperature, hollow parts with high internal pressure and decreasing trend in installation space. All products have a big advantage, it's more extensive processing of space, which will help to create a stable, cost-effective welding, ' joint LANXESS technology expert Frank Krause said.
Welding of high strength
Durethan BKV 30 XWP, BKV 30 XWP HV and BKV 30 XWP XT is for heating, infrared (IR) vibration welding technology specially developed material and Durethan BKV 30 XWP LT is for the development of laser transmission welding. All four are made of 30% polyamide 6 grades of glass fiber reinforcement. Abbreviation for 'XWP' ' excellent welding performance.
Durethan BKV 30 XWP meets the user of infrared, vibration and stability of heated tool welding technology and welding strength and tolerance of higher demand. Its flexural strength is slightly higher than standard polyamide 6 – – Durethan BKV 30 H2.0. Potential areas of application include the intake manifold and modules.
BKV 30 than XWP, Durethan BKV 30 XWP HV (high viscosity) has the advantage of its high melt viscosity, which will broaden the scope of vibration and the heated tool welding processing, so it is of great advantage. ' This compound showed very high mechanical strength. For example, by a standard polyamide 6 (30% fibreglass) compared to equivalent products made, two four-cylinder engines intake manifold burst strength of a raised 16%, another 40% is lifted, 'Krause said.
High temperature environment with long-term stability
Noteworthy products are heat-stable material BKV 30 XWP XT (extreme heat) and can be used for continuous operating temperature up to 200 ° c. ' As far as we know, this high quality polyamide material either at room temperature or in a high temperature environment is in the engine compartment has a high weld strength after aging, unique in the market, 'Krause said. Melt viscosity can be compared with the Durethan BKV 30 XWP HV, and thus also an advantage in the process. Possible areas of application include pipe and intake manifold and the hollow part of the circuit.
Weld area of rapid heating
Durethan BKV 30 XWP LT (laser transmission) in a typical wavelength of laser transmission welding range showed higher laser transmission. ' The material to ensure fast and efficient heat transfer to the weld area, so as to enhance the manufacturing price, 'Krause said. This new polyamide material has a variety of natural colors and a special black available. Possible applications include fuel tank, airbags and other sensor housings, welded to cover housing and internal complex geometric configurations of hollow parts with mechanical sensitivity (such as air).
Hydrolytic stability and laser transmission
Pocan PBT compounds B3235 LT and B3235 HR LT is also customized for laser transmission welding, more natural tone and choice of near infrared laser transmission black, its laser transmission and performance than other products on the market. 'Pocan B3235 HR LT has very good hydrolytic stability, especially in engine compartment parts have to heat water. Our materials by laser welding control equipment (such as electric parking brake) housing parts also have a very good chance, 'Pocan product developer Joachim Morick said. Compare with Pocan B3233 HR, its typical of laser transmission in laser welding between 800 to 1,200 nm wavelength range can be more than twice times. Not exposed to high temperatures and humid environment of PBT in laser welding parts can choose Pocan B3235 LT material, laser transmission near the standard of such PBT Pocan B3235 twice.
