POM

Polyoxymethylene (POM) is a semi-crystalline thermoplastic technopolymer, with high mechanical strength, used for the production of precision parts that require high rigidity, low coefficient of friction and great dimensional stability. POM has excellent flowability, resistance to wear and low moisture absorption.

Technical features:

Excellent mechanical strength, rigidity, hardness and low coefficient of friction
Good resistance even at low temperatures
Low moisture absorption
Low tendency to deform
High dimensional stability and hydrolysis resistance
Low abrasion resistance and non-self-extinguishing
No UV radiation resistance
Low resistance to strong acids

Polyamides are the most widely used thermoplastics and they have the advantage of having excellent mechanical properties which are maintained constant even at high and low temperatures. They are also resistant to various chemical agents and to breakage: their hardness, toughness, low coefficient of friction and high attenuation power make them preferred in many applications in the various fields of the mechanical industry.

Technical features:

High mechanical strength even at high temperatures (up to 110°C) and in harsh environments
Good resistance to breakage, traction, compression and impact
Low coefficient of friction and abrasion
Excellent resistance to machine oils and greases
Good resistance to aging and atmospheric agents
Resistance to stress, it maintains the characteristics even under repeated stresses
No resistance to concentrated acids
High moisture absorption (not suitable for the electrical industry).

UHMW-PE

UHMW-PE polyethylene is an ultra-high molecular density pressed technopolymer. Insolubility, excellent chemical resistance and good insulation are its main qualities. It is a very versatile plastic material used in many fields, offering wear durability and good flowability characteristics. Though very stable for all machining operations, it is not suitable for tight tolerances due to deviations stemming from thermal expansions. As a matter of fact, operating temperatures must be between -200°C and 80°C.

Technical features:

Insoluble
Good insulation properties
Excellent workability with low specific weight
Good flowability
Good shock resistance
Resistance to chemical agents
Physiologically harmless
Suitable for handling food products
Operating temperatures range between -200°C and 80°C.

PEEK

A semi-crystalline thermoplastic that combines excellent mechanical characteristics, good chemical resistance, PEEK - above all - can be used up to 260°C in hot water or steam. It is also ideal for low temperatures, up to -60°C. Besides having great chemical and mechanical resistance, it also has low permeability to highly aggressive substances such as H2S, CO2, methane and hydrocarbons. It has the highest coefficient of tensile strength coefficient in the plastics family.

Technical features:

Lightness
Good dielectric and insulating properties
Low coefficient of moisture absorption
Chemically resistant and insoluble to all common solvents
Excellent strength, rigidity and dimensional stability even at high temperatures
High resistance to X-rays and gamma rays
Approved by EU and FDA regulations for the Food Industry
Not UV-stable
