Engineering Plastics

PA6 E (PolyAmid 6 extruded)

An optimal combination of various properties

  • mechanical stability
  • Rigidity
  • Durability
  • Mechanical attenuation
  • Good wear resistance
  • Good electrical insulation properties
  • good chemical resistance
All of these characteristics make PA6 E a universally suitable material for mechanical engineering and plant construction.

PA6 G (PolyAmid 6 Cast)

PA6 Cast, in contrast to the extruded polyamides, is produced through an unpressurised casting process. This homogenous material therefore has lower internal pressure. Thanks to the unpressurised manufacturing technique, PA6 Cast can be produced in large dimensions.

  • High mechanical strength, rigidity, and hardness
  • Good wear properties
  • Good heat aging resistance
  • Large dimensions possible
For improved friction characteristics, various materials can be added:
  • PA6G + Oil (Ertalon® LFX)
  • PA6G + MoS²(Nylatron® GSM)
  • PA6G + PE (Nylatron® NSM)
For increased heat aging resistance:
  • PA6G + Heat stabiliser (Ertalon® 6 XAU+)
  • Rollers and wheels
  • Sliding bearings and friction plates
  • Gear wheels
  • Sliding profiles
  • Sockets, coils and discs

PA6.6 (PolyAmid 6.6)

  • PA6.6 is amongst the unreinforced PA-Type materials with the highest strength, rigidity, abrasion resistance and heat resistance
  • High wear resistance
  • Higher PV threshold value
The characteristics of PA6.6 can be modified by specific additions:
  • PA6.6 + MoS2 = Improved antifrictional properties and dimensional stability
  • PA6.6 + PE = Improved antifrictional properties
  • PA6.6 + Fibreglass = increased strength and rigidity
  • PA6.6 + carbon fibre = increased rigidity and resistance to heat distortion plus improved antistatic properties
  • Plain bearing bushes
  • Plain bearing plates and guides
  • Gear wheels
  • Pulleys
  • Rings, discs, cams and casing

PA4.6 (PolyAmid 4.6)

Due to increased rigidity and higher creep strength, this material can be used over a wide range of temperatures. The heat aging resistance at high temperatures (80-150°C) is also significantly superior to that of all PA types, even POM and PETP.

PA 12E (PolyAmid 12 extruded)

Compared to the other PA types.

  • Lightweight
  • Higher impact resistance
  • Low water absorption
  • Better insulating properties
  • good chemical resistance

PA12 G (PolyAmid 12 Cast)

PA12 Cast is produced through an unpressurised pouring process. In this production, the molecule chains in the material (check) can arrange themselves freely because of the polymerisation This leads to a high crystalline structure and mostly zero potential parts.

This is how PA12 Cast is highly superior to other polyamides for certain applications.

  • Extremely high durability (including in low temperatures up to -80°C)
  • Higher mechanical and thermal resistance
  • Outstanding antifriction properties
  • Good chemical resistance
  • Good emergency running properties
  • Highly loaded gears
  • Rollers
  • Propellers
  • Sliding and bearing bushes
  • Cams, work gears, conveying elements
By casting a steel core, a permanent connection between the core and the plastic is produced. The gears, rollers, bearings and bushes made in this way possess the same properties as those made from a steel-steel combination. The strong characteristics of this plastic are also evident outdoors.

POM (PolyOxyMethylen)

POM is a very versatile material with a balanced profile. Properties of POM include.

  • Very hard and strong
  • Good antistatic properties
  • High abrasion resistance
  • Very good damping features
  • Low water absorption (dimensionally stable)
  • Good resistance to organic solvents
  • BGA and FDA approved
The good basic properties of POM can, of course, be improved by additions:
  • POM + Fibreglass = increased strength and rigidity
  • POM + PE = Improved antifrictional properties
  • POM + PTFE = Improved antifrictional properties
  • POM + conductive soot = no static charge, conductibility
  • POM + soot free antistatic agent (Semitron® ESd 225)
  • Bearing bushes
  • Bearing plates and sliding profiles
  • Guides
  • Gears, gear racks
  • Moulded parts for packing machines
  • Rollers and wheels

PET (PolyEthylene Terephtalate)

The main properties of this crystalline thermoplastic polymer are:
  • High rigidity
  • Very hard
  • Low friction coefficient
  • High dimensional stability
  • Good resistance to acids
  • Good electrical insulation properties
  • Physiologically safe (BGA and FDA approved)
  • Low moisture absorption
The basic qualities can be modified by the addition of various materials:
  • PET + solid lubricant= improved antistatic properties, self-lubricating (Ertalyte® TX)
  • PET + Fibreglass = increased strength and rigidity
  • Sliding and bearing bushes
  • Sliding and bearing discs
  • Worm gears
  • Wheels and rollers
  • Guides, cams and casing
  • Pumping elements
  • Parts for precision mechanics
  • Parts for electrical use

PPE (PolyPhenyle Enoxide)

PPE is an amorphic thermoplastic modified with polystyrol for easier processing

  • High impact resistance
  • Dimensional stability in heat up to +130°C
  • Good hydrolysis resistance
  • Low moisture absorption
  • Good electrical and dialectical properties
  • Physiologically safe (FDA and BGA approved)
  • Sterilisable
By adding 30% fibreglass to the base material, the strength, resistance to pressure and dimensional accuracy are increased.

  • Electronic equipment
  • Electrical plant construction
  • Elements for plumbing and bathroom (steam)
  • Components for precision engineering
  • Household appliances

PC (PolyCarbonate)

Industrial quality for machine production of shaped parts

The amorphous structure makes this material transparent with high light transfer. This material is, however, susceptible to stress corrosion cracking.

  • High mechanical stability
  • Very hard
  • Good creep strength
  • Good impact resistance and rigidity over a wide range of temperatures
  • Good dimensional stability
  • Low moisture absorption
  • Good electrical and dialectical properties
