Tauberzel, Germany, October 11, 2018: A new line of high temperature glass reinforced PA 66 compounds can compensate for the price/performance gap between standard high temperature polyamides and costly specialty polymers, providing injection molding manufacturers with more An economical alternative to automotive and other metal replacement parts. At the 2018 German Plastics Show, Teknor Apex will introduce a variety of new materials during technical talks at its booth (B2-2114).
The Creamid® 240 H7.5 series of compounds provides the strength and hardness of high glass filled engineering polymers and maintains a high level of critical mechanical properties even at temperatures up to 240 ° C. Currently, this range of compounds Available in a variety of grades of 35%, 50% or 60% glass, the performance retention is significantly improved compared to similar glass-filled standard PA 66 compounds (see figure). At the same time, their per kilogram The cost is about 30% lower than high performance polymers such as polyphthalamide (PPA) or PA 4.6, while providing comparable performance.
Hartmut Elsässer, Director of Global Engineering Thermoplastics Technology, said: 'The use of Cruamid 240 H7.5 compounds allows for additional cost savings during processing. Compared to high-performance products such as competitive PA 66 compounds and PPA, these new materials Melting and lower mold temperatures provide economic advantages in terms of energy consumption, cycle time and tooling requirements.'
At the same time, these new compounds have processing temperatures ranging from 280°C to 300°C, mold temperatures ranging from 80°C to 110°C, and corresponding ranges for PPA or PA 4.6 of 330°C. Between 350 ° C and between 130 ° C and 150 ° C (see photo).
Teknor Apex recommends the use of Cruamid 240 H7.5 compounds in automotive engine compartment components such as charge air cooler end caps, intake manifolds, quick mount fittings, radiator end tanks, turbine ducts and resonators, oil pumps Wheels, EGR valves and thermostat housings. Other possible applications include electronic connectors, diode holders and bobbins, as well as consumer products such as lamp holders and connectors.
Markus Krippner, Director of Sales and Marketing, said: 'Although metal replacement will continue to drive demand for polyamides in the automotive market, performance-enhancing technologies such as turbocharged engines and advanced shifting systems have heat resistance, chemical resistance and lower water absorption. More stringent requirements have been put forward. These influences and the industry's overwhelming efforts to reduce vehicle weight will drive Teknor Apex's investment in new polyamide technology.'
Mr. Krippner pointed out that lightweighting requires materials that provide high strength, low creep levels and excellent processability. 'Creamid 240 H7.5 compounds have a variety of flow characteristics that can easily accommodate complex or thin-walled parts or long runners And these are usually requirements for metal substitution. '
During the German Plastics Exhibition, Dr. Elsässer will be on the Teknor Apex booth at 1:00 and 3:00 pm on Tuesday, Wednesday and Thursday (ie October 16, 17 and 18) on the Cruamid 240 H7.5 Demonstration of the compound.
Creamid 240 H7.5 compounds are available worldwide. In addition to glass-filled compounds, non-enhanced formulations with operating temperatures up to 200 ° C are available. As a custom compound manufacturer, Teknor Apex can work with customers to meet Specific feature requirements.
