Polyamides and Intermediates

Polyamides for Extrusion

Ultramid® extrusion grades are offered in a wide variety of combinations of viscosity and additives. Their outstanding properties have made them indispensable for transparent and flexible food packaging, medical packaging, monofilament applications (e.g. fishing lines, fishing nets, lawn trimmers) and cable sheathing.

Films

Polyamide as the ideal solution for flexible films

Ultramid® is especially well-suited for flexible films, e.g. packaging, due to its unique mechanical, optical, thermal, barrier and processing performance.

Supply form and storage

Ultramid® is supplied as pre-dried pellets ready for processing in a variety of moisture-proof containers such as bags, octabins, big bags and loose bulk.

To ensure that the perfectly dry material delivered cannot absorb moisture from the air, the containers must be stored in dry rooms and always carefully resealed after any material is removed. Containers stored in cold rooms should be allowed to equilibrate to normal temperature before opening so that no condensation occurs on the pellets. 

Safety precautions during processing

Like all thermoplastic polymers, Ultramid® also decomposes when exposed to excessive heat, such as overheating or cleaning by burning off, forming gaseous decomposition products. As well as caprolactam (with Ultramid® B (PA 6) and C (PA 6/66)), ammonia and carbon monoxide are formed above approximately 310°C. Above approximately 350°C, small quantities of pungent-smelling vapors of aldehydes, amines and other nitrogenous decomposition products are also formed.
In general, measures should be taken to provide ventilation and venting of the workplace, preferably by means of an extraction hood over the cylinder unit.
