Polyamide modifications

Ensinger also offers polyamides (PA6, PA6G, PA66, PA12, PA46) in a variety of different modifications.

TECAM 6 MO

The addition of molybdenum sulphide (MoS2) to PA6 results in an increase of rigidity, hardness and dimensional stability due to its nucleating effect. Conversely, the material's impact strength is reduced as a result. The additive also lends the material improved sliding friction properties.

  • High rigidity
  • High degree of hardness
  • Good dimensional stability
  • Lower impact strength
  • Good fatigue strength
  • Good mechanical damping properties
  • Good sliding friction properties
  • Good abrasion resistance

TECAMID 6 GF30

This 30 % glass fibre reinforced TECAMID 6 demonstrates higher strength, rigidity, creep strength and dimensional stability than unreinforced TECAMID 6.

  • Very high rigidity
  • High mechanical strength
  • High degree of hardness and toughness
  • High creep strength
  • Very high dimensional stability
  • Good fatigue strength
  • High mechanical damping properties

These properties make this material suitable for use in parts which are exposed to high static loads over long periods in high temperature conditions.
As glass fibres tend in some cases to have a marked abrasive effect on mating surfaces, TECAMID 6 GF30 is less suitable for sliding applications.

TECAMID TR

Due to its chemical structure, TECAMID TR is one of the amorphous polyamides and is consequently transparent. The amorphous structure also brings about slight shrinkage and tendency to warp. In addition, feedstocks demonstrate high chemical and stress crack resistance.

  • High degree of transparency
  • High mechanical strength
  • High thermal dimensional stability
  • High degree of toughness
  • Good chemical resistance
  • Good electrical characteristics
  • Good dimensional stability

TECAST TM

TECAST TM is a TECAST T material modified by the addition of molybdenum sulphide (MoS2). The addition of MoS2 brings about an increase in the degree of crystallinity, lending the cast polyamide a higher degree of strength – without any appreciable deterioration of toughness. In addition, increasing the crystallinity results in improved surface hardness and better abrasion properties.

  • High strength
  • Good level of rigidity
  • Good degree of hardness / surface hardness
  • High degree of toughness
  • Good abrasion resistance also at high temperatures
  • Good sliding friction properties

TECAST L

TECAST L is a cast polyamide modified with a special oil as a lubricant, which is particularly suitable for sliding applications - also in dry running conditions. Homogenous distribution of the lubricant ensures consistently high sliding and abrasion behaviour over the entire service life. Particularly notable is also low stick-slip susceptibility and a very low sliding wear rate.

  • High strength
  • Good level of rigidity
  • High degree of toughness.
  • Very good abrasion resistance also at high temperatures
  • Very good sliding friction properties
  • Very good stick-slip behaviour

  • Very good emergency running properties

TECAGLIDE

Like TECAST GX, the material TECAGLIDE is a cast polyamide modified with a special solid lubricant. Due to its very good sliding wear properties and very good stick-slip behaviour, this material is particularly suitable for sliding applications - also in dry running conditions.

  • High strength
  • Good level of rigidity
  • High degree of toughness
  • Very good abrasion resistance also at high temperatures
  • Very good sliding friction properties
  • Very good stick-slip behaviour
  • Very good emergency running properties

TECARIM 1500

TECARIM 1500 is a PA6 block copolymer processed using the reaction injection moulding process. Its elastomer component makes this a tough material capable of withstanding high levels of stress.

  • Very high level of toughness
  • Good low temperature impact strength
  • Low strength
  • Low hardness
  • No brittle fracture
  • Good shock absorption
  • Electrically insulating

TECARIM 4000

Like TECARIM 1500, TECARIM 4000 is a PA6 block copolymer processed using the reaction injection moulding process. The difference between the two materials is a higher elastomer component of 40%. As a result of this higher elastomer component, the material offers even greater toughness, which makes for substantially higher impact strength but markedly lower strength.

  • Very high level of toughness
  • Very good low temperature impact strength
  • Very low strength
  • Low hardness
  • No brittle fracture
  • Very good shock absorption
  • Electrically insulating

TECAMID 66 HI

TECAMID 66 HI features a special additive which reduces the thermal degradation of molecular chains. As a result of using this additive, higher service temperatures of around 15°C are achieved compared to standard PA66 types.

  • Higher application temperature resistance
  • Lower thermal degradation
  • Lower strength, hardness
  • High degree of toughness

TECAMID 66 GF30

This 30 % glass fibre reinforced TECAMID 66 demonstrates higher strength, rigidity, creep strength and dimensional stability than unreinforced TECAMID 66.

  • Very high rigidity
  • High mechanical strength
  • High degree of hardness and toughness
  • High creep strength
  • Very high dimensional stability
  • Good fatigue strength
  • High mechanical damping properties

These properties make this material suitable for use in parts which are exposed to high static loads over long periods in high temperature conditions. As glass fibres tend in some cases to have a marked abrasive effect on mating surfaces, TECAMID 66 GF30 is less suitable for sliding applications.

TECAMID 66 CF20

This is a 20% carbon fibre reinforced PA 66. This fibre reinforcement brings about increased rigidity, mechanical strength and creep strength coupled with lower density and lower dosing in comparison with 30% fibre filled TECAMID 66 GF30. Alongside these properties, the carbon fibres behave less abrasively than glass fibres and at the same time result in better sliding properties. Through the addition of carbon fibres, in addition a significantly higher heat conductivity is achieved, ensuring fast dissipation of friction heat which is also beneficial for sliding applications.

  • High mechanical strength
  • High rigidity
  • High creep strength
  • Very good sliding and wear properties
  • Good dimensional stability
  • Excellent chemical resistance

TECAMID 66 LA

TECAMID 66 LA is a material benefiting from an added solid lubricant. The solid lubricant improves the sliding friction properties as well as abrasion behaviour compared to TECAMID 66. In addition, however, the additive causes the material to have lower strength, rigidity and hardness.

  • Good sliding friction properties
  • Low wear
  • Low deformation
  • High degree of toughness
  • Good chemical resistance
  • Low strength rigidity
  • Low hardness

TECAMID 66 MH

The addition of molybdenum sulphide (MoS2) to PA66 produces a material with improved sliding friction properties. This is achieved as a result of the additive's structure and its nucleating effect. This effect also brings about an increase in rigidity, hardness and dimensional stability. Conversely, the material's impact strength is reduced.

  • High rigidity
  • High degree of hardness
  • Good dimensional stability
  • Lower impact strength
  • Good fatigue strength
  • Good mechanical damping properties
