Ultramid®

BASF’s Ultramid® grades are molding compounds on the basis of PA6, PA66 and various co-polyamides such as PA66/6. The range also includes PA610 and semi-aromatic polyamides such as PA6T/6. The molding compounds are available unreinforced, reinforced with glass fibers or minerals and also reinforced with long-glass fibers for special applications. Ultramid® is noted for its high mechanical strength, stiffness and thermal stability. In addition, Ultramid® offers good toughness at low temperatures, favorable sliding friction behavior and can be processed without any problems.

The most important properties of Ultramid®

  • High strength and rigidity
  • Very good impact strength
  • Outstanding resistance to chemicals
  • Low tendency to creep
  • Dimensional stability
  • Simple processing

Ultramid® ‒ versatility in material and application

Because of the manifold and tailor-made characteristics of Ultramid® many applications are possible, especially in automotive construction, electrical engineering and electronics, in household technology, industrial connection, photovoltaics, in construction and installation, furniture, the sanitary industry and in mechanical engineering.

Properties of Ultramid® (PA)

Ultramid® is the trade name for polyamides supplied by BASF for injection molding and extrusion. The product range includes PA6 grades (Ultramid® B), PA66 grades (Ultramid® A), special polyamides like PA6T/6 (Ultramid® T) and PA610 (Ultramid® S Balance) as well as special grades based on copolyamides. Ultramid® A is produced by condensation polymerization of hexamethylene diamine and adipic acid, Ultramid® B by hydrolytic polymerization of caprolactam. These materials are obtained from petrochemical feedstocks such as benzene, cyclohexane and p-xylene. Ultramid® is noted for its high mechanical strength, stiffness and thermal stability. In addition, Ultramid® offers good toughness at low temperatures, favorable sliding friction behavior and can be processed without any problems.

Processing of Ultramid®

Ultramid® can be processed by all methods known for thermoplastics. The main methods are injection molding and extrusion. Complex moldings are economically manufactured in large numbers from Ultramid® by injection molding. The extrusion method is used to produce films, semi-finished products, pipes, profiled parts, sheet and monofilaments. Semi-finished products are usually further processed by cutting tools to form finished molded parts.

The Ultramid® product range 

The basis of the Ultramid® grades are polyamides which are supplied in a variety of molecular weights or viscosities, have a range of additives and are reinforced with glass fibers or minerals. More detailed information on the individual products can be found in the Ultramid® product range.

The Ultramid® range comprises the following groups of products:

Ultramid® A

in its unreinforced state, it is an extremely rigid, abrasion-resistant, heat-resistant and hard material . It is one of the preferred materials for parts subject to mechanical and thermal stresses in electrical, mechanical and automotive engineering.

Ultramid® B

in its unreinforced state, it is a tough, hard material affording parts with good damping characteristics and high shock resistance even in dry state and at low temperatures. It is particularly tough and easy to process. Translucent products are also available under the name Ultramid® Vision.

Ultramid® C

is the name given to copolyamides made from PA6 or PA66 monomers that exhibit different melting points or a lower crystallinity according to their composition.

Ultramid® D

are blends of PA6 and PA66 and other polyamides with customized properties, available as unreinforced grades (e.g. Ultramid® Deep Gloss D3K) and reinforced grades (e.g. Ultramid® Endure D3G10 BK20560).

Ultramid® S Balance

is particularly resistant to chemicals and is also known for its low moisture absorption. Ultramid® S Balance is preferably used in components that come into contact with media.

Ultramid® T

has a semi-aromatic structure and is a highly rigid material with a high melting point, known for its dimensional stability, high chemical resistance and constant mechanical properties covering a wide range of different applications.

Glass-fiber reinforced Ultramid® 

These materials are distinguished by high mechanical strength, hardness, rigidity, thermostability and resistance to hot lubricants and hot water. Parts made from them show dimensional stability and high creep strength. Glass-fiber reinforced Ultramid® T also has extraordinarily high heat resistance (up to 280°C). 

Reinforced and unreinforced grades with flame retardants

The modified Ultramid® grades C3U, A3X2G5, A3X2G7, A3X2G10, B3U50G6, A3U42G6, B3UG4, B3U30G6 and T KR 4365 G5 are particularly suitable for electrical components with high flame retardance and high tracking resistance.

Mineral- and glass bead-filled Ultramid®

Materials filled with minerals and glass beads show increased rigidity, good dimensional stability, low tendency to warp, optically appealing surfaces, partly excellent ability for metallizing and good flow characteristics.

 

Ultramid® Advanced N

is characterized by very low water absorption, excellent chemical resistance and good mechanical properties at high temperatures in conditioned state.

Ultramid® Advanced T1000

has a very high, constant stiffness and strength over a temperature range of -40°C to over 80°C. It is resistant to high temperatures and against aggressive media.

Ultramid® Advanced T2000

is a polyphthalamide providing good E&E performance with a high melting point, low water absorption, good mechanical properties at high temperatures and good chemical resistance.
