Materials

Semi-finished products made of POM, like the ones produced by us, are characterised in particular by their high mechanical strength, good dimensional accuracy and great machinability (short chips facilitate machining on CNC machines).

These factors have made POM a technical plastic that is frequently able to replace metallic materials. In instances where it is used, this results not only in technical improvements, but also in a considerable reduction in costs.

The most noteworthy properties of semi-finished products made of POM are:

• High mechanical strength
• Good toughness, even at low temperatures
• Good spring properties
• Good dimensional accuracy
• Low water absorption
• Good machinability
• Favourable sliding friction behaviour
• Good chemical resistance (in particular against highly alkaline media)
• Good recyclability

PET is a thermoplastic polyester that is distinguished by its very high mechanical strength and hardness in addition to a very low coefficient of friction.

Its outstanding properties make this plastic also ideally suited for the substitution of metallic materials in many applications.

Its machinability is characterised by short chips, which, as is the case with POM, enables cost-effective machining on CNC machines.

Its coefficient of thermal expansion, which is lower than that of other thermoplastics, ensures good dimensional accuracy especially when dealing with small tolerances.

The main characteristics of PET semi-finished products are:

• good gliding and wear behaviour
• very high mechanical strength
• good stiffness and hardness
• good dimensional accuracy
• low water absorption
• good machinability
• good chemical resistance
• good recyclability
• not resistant to hot water (permanent exposure 60 °C)

In many aspects, polypropylene is similar to PE in terms of its properties.

However, because of its comparatively higher stiffness and higher service temperature than PE, it has established itself in a different range of applications.

PP is characterised by the following properties:

• very low density
• high hardness, stiffness and mechanical strength in the field of polyolefins
• relatively high heat deflection temperature
• low low-temperature viscosity down to approx. 0 °C
• good chemical resistance
• very low water absorption

In the field of technical plastics, polyethylene has achieved an excellent position thanks to its high impact resistance even at low temperatures, good electrical insulation properties and its low coefficient of sliding friction.

Its chemical resistance to acids, lyes, saline solutions etc. makes it the material of choice in many areas.

The following properties of PE stand out it in general:

• high toughness and elongation at break, even at low temperatures
• good chemical resistance
• low coefficient of sliding friction
• very low water absorption
• limited mechanical properties
• poor adhesion

PE-HD is characterised by the following properties:

• bondable
• good damping characteristics

PE-1000, in turn, is characterised by the following properties:

• comparatively high wear resistance
• low service temperature of down to –150 °C
