Ultraform® is the brand name for BASF’s polyoxymethylene product range. It comprises versatile engineering plastics having a wide array of properties designed for use in sophisticated components that are capable of withstanding high stresses.
So Ultraform® is suitable for many applications in automotive manufacturing, in medical technology, for household and recreation, but also for machine and plant construction.
Ultraform® advantages are:
- high rigidity and stiffness
- good resilience properties
- excellent resistance to chemicals
- dimensional stability
- low water absorption
- low tendency to creep
- excellent sliding friction properties
Nomenclature:
Letters for identifying the melt flow rate:
The melt flow rate corresponds to the position of the letters in the alphabet: The later the letter appears in the alphabet, the higher the melt flow rate. Usually one of the letters E, H, N, S, W or Z is used. The following rule applies:
E Lowest flow rate, lowest MVR value
Z Highest flow rate, highest MVR value
Letters for identifying the type of reinforcing agent, filler, modifier or additive used:
E Impact-modified with rubber
G Glass fibers
K Chalk
L Conductive carbon black
M Mineral
P Special lubricant
U UV-stabilized
Z Impact-modified with thermoplastic polyurethane
Characteristic numbers for describing the content of reinforcing agents, fillers or modifiers:
The numbers 2, 4, 5, 6 and 9 are usually found. The greater the number, the higher the content. The following rule applies:
2 approx. 10% by mass
4 approx. 20% by mass
5 approx. 25% by mass
6 approx. 30% by mass
9 approx. 45% by mass
Suffixes
Suffixes are optionally used in order to indicate specific processing or application-related properties. They are frequently acronyms whose letters are derived from the English term.
Examples of suffixes:
- Aqua® Meets specific regulatory requirements for drinking water applications
- FC Food Contact; meets specific regulatory requirements for applications in contact with food
- LEV Low Emission Version; low in odors
- PRO Profile Covered Raw Materials Only; meets specific regulatory requirements and needs for medical applications
