Pebax block polyetheramide elastomer products are engineering polymers that are plasticizer-free thermoplastic elastomers. The product has a wide range of hardnesses, good resilience, easy processing properties and the properties of polyamide products. Its remarkable processing properties make it ideal for the production of components: excellent flexibility/softness (wide range, good feel, good tactility);
excellent low-temperature impact resistance; very good dynamics due to low hysteresis; very little change in properties between -40°C and +80°C; corrosion resistance to most chemicals, excellent aging and sunlight exposure resistance. Very little change in properties between -40°C and +80°C, no hardening at low temperatures; Corrosion resistance to most chemicals, excellent resistance to aging and sunlight exposure.
Applications:
Pebax products have a wide range of applications due to their many properties.
Developed over 25 years ago by researchers at Arkema in France, Pebax high-tech polymers have been continually refined and are now the better choice for plastic equipment manufacturers in many countries. It is widely used in medical Pebax catheters and other convenient applications.
Low Temperature Impact Resistance
Pebax conduit is known to have good elasticity, even at very low temperatures, which leads to its strong impact properties. Impact testing determines the amount of energy required to deform and destroy a material or structure at high rates of deformation. Thanks to a number of methods, the impact force can be measured, but the technique more accepted by Pebax is the Izod or Charpy test. The energy required to destroy a material is obtained by calculating the difference in energy of the pendulum before and after impact. Tests can be performed at both room and low temperatures, using a variety of sample geometries and notch types. Whichever method is feasible, Pebax materials are able to demonstrate excellent impact resistance at both room and low temperatures.
Processability
Pebax has strong processing properties in each of the major thermoplastic processing technologies, which are injection molding and extrusion (cast film, blown film, sheet, tube, etc.). The shrinkage of Pebax typically varies from 0.5 %到1.5%depending on the Pebax grade selected and the injection molding conditions. The rheological behavior of Pebax allows for a wider range of processing temperatures than other thermoplastic elastomers, especially TPU. Pebax can be injected into extremely thin parts, typically as small as 0.8 mm. It also allows for shorter cycle times, high recyclability and accurate dimensional controllability.
