In-depth analysis of the physical properties and characteristics of different raw material wires

Released on Jun. 07, 2023

We use wires made of PET, PPS, PEEK, PA, antistatic and other materials for product production.  Through intensive cooperation with various material manufacturers, our raw materials are optimally matched to our production technology as well as their possible applications.


PET (Polyethylene Terephthalate)

PET is a versatile and widely used thermoplastic polymer that belongs to the polyester family. It is known for its exceptional clarity, strength, and lightweight properties.


PET has a high surface hardness, has high strength and rigidity with very good dimensional stability, has very good sliding properties, high chemical resistance and high wear resistance. PET withstands high mechanical loads, shows little deformation, absorbs only minimal moisture and is an ideal material for heavy-duty sliding applications.

PPS (Polyphenylene Sulfide)

PPS is a high-performance thermoplastic polymer known for its exceptional heat resistance, chemical resistance, and mechanical properties. It is a semi-crystalline material that belongs to the family of aromatic polymers. PPS exhibits excellent dimensional stability and is often used in demanding industrial applications where high temperature and chemical resistance are required.


The connection of aromatic monomer units via sulfur atoms results in particularly resistant polymers whose good mechanical properties are retained even at temperatures well above 200 °C, so that continuous use of up to 240 °C is possible, depending on the load. Stresses at temperatures of up to 270 °C are also briefly withstood.

The chemical resistance of the PPS to almost all solvents, many acids and alkalis and, to a limited extent, to atmospheric oxygen, even at high temperatures, is outstanding.

Mechanical Properties: PPS offers excellent mechanical strength, stiffness, and dimensional stability. It has a low coefficient of thermal expansion, meaning it experiences minimal size changes with temperature variations. PPS also has good creep resistance, fatigue resistance, and impact strength, making it suitable for demanding mechanical applications.


PPS has excellent dimensional stability, maintaining its shape and size over a wide range of temperatures. It exhibits low water absorption, ensuring minimal dimensional changes even in high humidity environments.

  • Approximate melting point: 285°C

  • Modulus of elasticity: 4000 MPa

  • Water absorption: 0.05%

  • Very good chemical resistance, resistant to various fuels, oils, ethanol, freon, xylene

  • Coefficient of thermal expansion: 0.5 10−4 K−1


PEEK (Polyether Ether Ketone)

PEEK is a high-performance thermoplastic polymer known for its exceptional mechanical, thermal, and chemical properties. It belongs to the family of polyaryletherketones and is widely used in industries where extreme performance and reliability are required. PEEK offers a unique combination of high temperature resistance, excellent strength, dimensional stability, and chemical resistance.

Here are the key characteristics and details about PEEK material:

  • Heat Resistance: PEEK exhibits remarkable heat resistance, with a high melting point of approximately 340°C (644°F). It can withstand continuous use at high temperatures without significant loss of mechanical properties. This makes PEEK suitable for applications in demanding environments, such as aerospace, automotive, and electronics industries.

  • Mechanical Properties: PEEK possesses excellent mechanical properties, including high tensile strength, stiffness, and impact resistance. It maintains its mechanical performance even at elevated temperatures, allowing it to withstand demanding load-bearing applications.

  • Chemical Resistance: PEEK demonstrates exceptional resistance to a wide range of chemicals, including acids, bases, solvents, and hydrocarbons. It retains its integrity and mechanical properties when exposed to aggressive chemicals, making it suitable for applications in chemical processing, oil and gas, and medical industries.

  • Dimensional Stability: PEEK exhibits excellent dimensional stability, meaning it maintains its shape and size under various temperature and environmental conditions. It has a low coefficient of thermal expansion, ensuring minimal dimensional changes even with temperature fluctuations.


PA (Polyamide)

PA is a versatile thermoplastic material that belongs to the family of synthetic polymers. It is known for its excellent mechanical properties, high strength, toughness, and chemical resistance. PA is widely used in various industries due to its versatility and wide range of applications.

Here are the key characteristics and details about PA material:

  • Mechanical Properties: PA exhibits excellent mechanical properties, including high tensile strength, impact resistance, and toughness. It can withstand heavy loads and has good resistance to wear and abrasion. PA is often used in applications where mechanical strength and durability are required.

  • Chemical Resistance: PA has good resistance to many chemicals, such as oils, solvents, and alkalis. It retains its mechanical properties and integrity when exposed to various chemicals, making it suitable for applications in the automotive, chemical, and industrial sectors.

  • Moisture Absorption: PA has moderate moisture absorption properties. It can absorb and release moisture, which may affect its dimensional stability. Special grades of PA are available with reduced moisture absorption characteristics for specific applications.

  • Heat Resistance: PA has a relatively high melting point, typically around 220-260°C (428-500°F). It retains its mechanical properties at elevated temperatures and exhibits good heat resistance, making it suitable for applications requiring thermal stability.
