1. Large choice of processing
Pebax® has excellent processability in each of the major thermoplastic processing technologies:
2. Handling recommendations
3. Drying Conditions
Granules exposed to atmospheric conditions for more than 2 hours should be dried prior to processing (see table below). Place the granules onto a clean flat metallic tray for efficient drying. Arkema highly recommends using vacuum drying ovens; higher temperature and time reduction is achieved with lack of oxygen. Desiccant dryers are also efficient with regularly changed filters. Risk of oxidation is greater with forced-air circulation ovens.
Bag storage conditions : Store away from moisture and heat, in ventilated atmosphere
4. Injection Molding Recommendations
Depending on the selected pebax® grade and injection conditions, the shrinkage rate of pebax® will typically vary from 0.5 to 1.5%.
Injection Molding Temperature Recommendations (°C) :
Mold Temperature (°C):
5. Dry-blending compatibility
With its extensive hardness range, pebax® is suitable for a vast majority of applications. It is possible, however, to mix various grades of pebax® in order to achieve more specific properties. ARKEMA personnel will be pleased to assist you in selecting the pebax® blend that best meets your specification.
6. Overmolding
Insert molding offers countless combinations of possibilities with a variety of materials such as glass, metals, polymers and textiles. The overmolding technique is widely used to manufacture soles of football and athletic shoes. Pebax® is highly suitable for these applications as it features a wide plasticizing range. The adhesion of pebax® onto inserts can be optimized by adjusting the process parameters. From a general stand point :
7. Extrusion Conditions of Pebax®
Thanks to the rheological properties of pebax®, the possibilities of extrusion and coextrusion are endless:
Pebax® can be extruded on conventional equipment. ARKEMA personnel will be pleased to provide specific processing parameters related to pebax® in technologies such as tube sizing, blown film drawing or sheet calendering.
