DSM ArnitelŪ PL650 Injection Grade Copolyester Elastomer (North America)

Subcategory: Elastomer, TPE; Polyester TPE; Polymer; Thermoplastic

Material Notes:
Product description: ArnitelŪ combines the advantages of engineering thermoplastics, being easy to process with excellent mechanical properties, at the same time with the flexibility of rubbers.

Arnitel does not require vulcanization. This leads to substantial reductions in part cost. Arnitel can be used over a wide range of temperatures. Arnitel has exceptional fatigue, creep resistance and resistance to oils, greases and many other chemicals.

Characteristics of Arnitel:

• Excellent strength over a wide range of temperatures
• Excellent dynamic properties e.g. creep and fatigue
• High heat resistance
• Exceptional resistance to oils and greases
• Good chemical resistance
• High degree of versatility in processing
• Easy coloring using masterbatches
• Surface quality from high gloss to textured
• Excellent heat resistance (long term 165°C)
• Good electrical insulation properties
• Low moisture absorption, excellent dimensional stability
• Easy flow, fast cooling times

Typical Applications:

• Automotive: ArnitelŪ is extensively used in the automotive industry for applications requiring exceptional fatigue resistance and resistance to oil and greases. Examples are: Rack and Pinion Bellows, Constant Velocity Joint Boots (CVJ Boots), Air brake tubings.
• Arnitel in the Electronic and Consumer Goods Industry: ArnitelŪ finds enormous potential and is also widely used in the consumer electronics by some of the world's best companies. ArnitelŪ is the best choice for low noise gears where their exceptional processability without any defects such as flash, makes it the material solution of choice. ArnitelŪ is also used in highly demanding applications such as in mobile phone antennas.

ArnitelŪ has exceptional flexibility and can perform or even outperform functions that normally require conventional rubbers. Available in a wide range of hardnesses, Arnitel can replace metals, thermoplastics, leather and rubber, often with a reduction in finished part costs.
