PEEK Monofilament

Products Details

PEEK is the abbreviation for polyetheretherketone, which is a high-performance thermoplastic engineering plastic.

PEEK has excellent mechanical properties, such as high strength, high stiffness, and good wear resistance; It has high temperature resistance and can be used for a long time at a high temperature of 260 ℃; Has excellent chemical stability and can resist the erosion of various chemical substances; It also has good electrical insulation and flame retardancy. Due to these excellent properties, PEEK has a wide range of applications in aerospace, automotive, electronics, medical and other fields.

01 PEEK

PEEK is a high-performance variety of polyaryletherketone polymers and is currently one of the most comprehensive thermoplastic polymers. The types of PEEK products are very diverse, mainly classified into injection molded finished parts, continuous extruded sheet/rod profiles, as well as films, capillaries, and other products.

Our company has developed various sizes and specifications of PEEK monofilaments (fibers) according to customer needs. PEEK filaments have excellent insulation properties, outstanding strength, and excellent heat and chemical resistance

02 Production process of PEEK monofilament (fiber)

PEEK filament, with a normal working temperature of 260 ℃, has inherent hydrolysis resistance and can be cleaned in high-temperature steam.

PEEK filaments are extruded from PEEK 5602G customized special raw materials, breaking the length limitations of traditional processes. They have a variety of diameters, are corrosion-resistant, heat-resistant, and have a certain degree of flexibility, making it easy to bend during the connection process.

03 Performance of PEEK monofilament (fiber)

PEEK (polyetheretherketone) monofilament (fiber) has excellent properties. Tensile strength of 600-700MPa (single filament fracture strength of about 50 cN/tex), elongation of 40%, melting point of 340 ℃, weight of 430 g/10000 m (diameter 0.2 mm).

04 PEEK monofilament (fiber) application fields

PEEK monofilament (fiber) has the characteristics of steam resistance, wear resistance, creep resistance, good toughness, and good biocompatibility. It is widely used in dry canvas, heat-resistant filter cloth, tennis racket mesh, composite materials (mixed with CF, GF, etc.), fuel filter screens, artificial ligaments, and high-temperature insulation sheaths on airplanes in paper making machinery.

Characteristic

◆ High temperature resistance

The long-term use temperature is 260 ℃. Even at temperatures as high as 300 ℃, good mechanical properties can still be maintained

◆ Wear resistance

PEEK polymer and its composite materials have good wear resistance in many extremely harsh application environments such as high temperature, high load, and strong corrosion.

◆ Self lubrication

It has a low coefficient of friction, can achieve oil-free lubrication work, and can work for a long time in media such as oil, water, steam, weak acid and alkali.

◆ Corrosion resistance

Insoluble in ordinary solvents, it has good corrosion resistance to various organic and inorganic chemical reagents.

◆ High strength

It has good mechanical strength in plastics. It also has high rigidity and surface hardness.

◆ Easy to process

Parts can be directly processed using injection molding technology. It can perform post-processing such as turning, milling, drilling, tapping, bonding, and ultrasonic welding.

◆ Resistant to hydrolysis

PEEK products can still work continuously for thousands of hours without significant performance degradation when immersed in steam at temperatures exceeding 250 ℃ or in high-pressure water.

◆ Flame retardancy

The flammability level of the 1.45mm thick PEEK sample is UL94 V-0 without the use of any additives.

◆ Low smoke and non-toxic

The amount of smoke and toxic gas is particularly low during combustion.

◆ Electrical performance

Stable and excellent electrical performance can still be maintained over a wide range of temperatures and frequencies.

◆ Radiation resistance

It has extremely strong resistance to high-dose gamma ray radiation, and its mechanical properties can be fully preserved, making it suitable as a radiation resistant component.

◆ Stable size

Our company's PEEK has a high temperature resistance of up to 260 ℃ and a short-term resistance of over 300 ℃, making it suitable for high-temperature working conditions. Excellent mechanical strength, fatigue resistance, wear resistance, and can replace metals as structural components. Strong chemical corrosion resistance, resistant to most acids, bases, and organic solvents. It also has self-lubricating properties, low moisture absorption, and is suitable for high-end industrial fields such as aviation and medical.
