Degussa AG Vestamid® E40-S3 Heat & Light Stabilized Nylon 12/PEBA Elastomer

Subcategory: Elastomer, TPE; Nylon; Nylon 12; Polyether Block Amide (PEBA); Polymer; Thermoplastic

Material Notes:
Description: Compared to other contending thermoplastic elastomers, PA 12 elastomers are distinguished by the following properties:

• They have low density.
• They are highly resistant to chemicals and solvents.
• They are easy to process and color and are easy to overmold.
• They can be decorated easily by means of heat transfer printing.
• They have excellent impact strength at low temperatures.
• Their hardness and flexibility can be varied over a wide range.
• They have high elasticity and good recovery.
• Their mechanical properties are only slightly temperature-dependent.
• They are free of volatile or migrating plasticizers.

Applications: noiseless gears, seals, functional elements of sports shoes, process aids in the extrusion of thermoplastic polyurethanes, films
