PEEK flange PEEK machined part

HONYPLAS®PEEK has the heat resistance and chemical stability of thermosetting plastics and the molding processability of thermoplastics. The long-term use temperature of PEEK is about 260-280°C, the short-term use temperature can reach 330°C, and the high pressure resistance can reach 30MPa. It is a good material for high-temperature sealing rings. PEEK products are suitable for various environments with harsh working conditions. PEEK also has excellent properties such as good self-lubrication, easy processing, stable insulation, and hydrolysis resistance, making it widely used in aerospace, automobile manufacturing, electrical and electronic, medical and food processing and other fields. Due to the unique performance advantages of PEEK materials, PEEK products can be widely used in many fields such as petrochemical, electronic and electrical, instrumentation, machinery and automobile, medical and health, aerospace, military nuclear energy and so on.

Flanges are devices used in the process of connecting, sealing and supporting mechanical parts. It is an indispensable and important part in the production of construction machinery. The general connecting parts are made of carbon steel and stainless steel. Among them, engineering plastics have many unique characteristics, such as chemical resistance, light weight and other advantages. Up to now, the plastic method PEEK is widely used in engineering, chemical, petroleum and other industries. Among engineering plastics, PEEK is the most widely used material.

The main reason for using Polyetheretherketone to produce plastic flanges is that polyetheretherketone material has the characteristics of extremely low friction coefficient, high wear resistance, light weight, high temperature resistance, and chemical corrosion resistance. These properties make it a better plastic flange than other flanges. At Zhenghao, we can provide you with compressed and extruded PTFE sheets, which can process plastic flanges of different sizes.

Advantages of HONYPLAS®PEEK plastic flanges over metal flanges:

(1) Good heat resistance, heat resistance up to 260 °C, suitable for high temperature occasions, and can also be used as a sealing material for a short time in a high temperature environment above 310 °C;

(2) There are no metal impurities in the material, and no leakage current will be generated during use;

(3) Strong chemical corrosion resistance, not afraid of chemical corrosion;

(4) The strength is relatively high, especially under the same stress conditions, the strength of PEEK plastic flanges is far superior to other materials;

(5) Light in weight and easy to install. If used in the same environment as stainless steel or copper, it can reduce the weight by more than 70% compared with stainless steel and more than 50% than copper;

(6) Good machinability, easy to process and shape, and used to make flanges of various sizes.

(7) It has excellent electrical insulation properties, the dielectric constant is extremely stable in a wide frequency range at room temperature, and the dielectric loss tangent is extremely small in the entire frequency range.

GRADES OF HONYPLAS®PEEK 

Virgin PEEK™

PEEK Machined Parts made from general purpose Unfilled PEEK™ is not reinforced and offers the highest elongation and toughness of all PEEK grades.
PEEK™ material is available in the following colors: light brown and black
Black PEEK™ is ideal for instrument components where aesthetics are important, as well as for seal components where ductility and inertness are important.
Unfilled PEEK™ grades comply with FDA regulation 21 CFR 177.2415 for repeated food contact.

30% Glass Filled PEEK™

30% glass filled PEEK™ parts have an increase in flexural modules and a reduction in expansion rate.
This grade is ideal for structural applications that require improved strength, stiffness, or stability, especially at temperatures above 300°F (150°C).
Glass-filled PEEK™ is only available in a light brown color.

30% Carbon Filled PEEK™

30% carbon filled PEEK™ parts have enhanced compression strength and stiffness and a dramatically lower expansion rate.
It offers designers optimum wear resistance and load carrying capability in a PEEK™-based product.
This grade provides 3½ times higher thermal conductivity than non reinforced PEEK™ — dissipating heat from the bearing surface faster.
Carbon-filled PEEK™ is black color.

Bearing Grade PEEK

PEEK Bearing grade parts, containing carbon fiber reinforced with graphite and PTFE lubricants, offers the lowest coefficient of friction and is the easiest grade of PEEK to machine parts from.
Bearing PEEK has an excellent combination of low friction, low wear, high limiting PV, low mating part wear, and easy machining.
Bearing grade PEEK™ is black or dark grey color .
