Polyetheretherketone (PEEK) is a high-temperature resistant and high-strength engineering plastic, mainly applied in oil pipelines, new energy vehicles, and semiconductor industry.
Dalian Allstar Material, through years of research and development and production, can now supply materials for most applications in the market, such as pure PEEK (no additives to PEEK), CF30 PEEK (PEEK with 30% carbon fiber added), GF30 PEEK (PEEK with 30% glass fiber added), bearing grade PEEK (with 10% carbon fiber, 10% PTFE, and 10% graphite added respectively). Verified by the market, our product quality is very stable.
As the name suggests, PEEK without any other materials added. This PEEK material is also the most widely applied. In addition to having excellent mechanical properties, pure PEEK material has the most excellent biocompatibility among all PEEK, and is often used in human body implants.
GF30 PEEK is produced by adding 30% by weight of glass fiber to PEEK material. Among all PEEK classifications, GF30 PEEK has higher strength, but the cost is lower than carbon fiber, and GF30 PEEK retains the electrical insulation performance of PEEK.

We can not only provide PEEK materials in various shapes, but also further process the materials, including PEEK injection molding, PEEK CNC, PEEK compression molding, etc.
PEEK injection molding is a process that melts PEEK resin pellets and injects them into molds to produce products with complex shapes and excellent performance.
This processing method is fast and has high output, suitable for small products.
PEEK sheets, rods, or tubes can be processed through CNC machining to obtain products with complex shapes.
PEEK CNC machining can meet customers' strict tolerance requirements and can machine complex geometric shapes that are difficult to achieve with injection molding processes.
PEEK compression molding is a process where PEEK powder is pressed and formed in high-temperature, high-pressure molds, usually used to produce large-sized, thick-walled component semi-finished products.
Due to the slow and uniform forming process, the internal stress of parts is effectively released, greatly improving dimensional stability and fatigue resistance.
Since 2012, we have started developing cable tie products. Cable ties are produced through injection molding process. After years of production and experience accumulation, the PEEK cable ties produced by Allstar Material have the following advantages:

| Glass Transition Temperature | 143℃ |
| Long‑term Working Temperature | -196°C (static components) ~ 260℃, instantaneous use up to 300℃ |
| Chemical Resistance | Except for concentrated sulfuric acid, it is basically insoluble in any solvent, strong acid, or strong alkali, and is hydrolysis resistant with very high chemical stability |
| Mechanical Properties | Has both rigidity and flexibility, particularly outstanding fatigue resistance under alternating stress, comparable to some alloy materials |
| Flame Retardancy | Has self‑extinguishing properties, can reach UL standard 94V‑0 level |
| Electrical Insulation Stability | Has good electrical insulation properties and maintains them to very high temperature ranges. Its dielectric loss is also very small under high frequency conditions |
| Fatigue Resistance | Has the best fatigue resistance among all resins |
| Hydrolysis Resistance | Outstanding hot water hydrolysis resistance characteristics, very low water absorption in high temperature and high humidity environments |
| Wear Resistance | Has excellent sliding characteristics, suitable for applications with strict requirements for low friction coefficient and wear resistance |
Because PEEK cable ties can withstand high temperatures, they are widely used in industrial fields that bear extreme thermal environments. This characteristic makes PEEK cable ties very suitable for applications with strict high-temperature performance requirements such as oil refining, aerospace manufacturing, automotive engine compartments, etc. This high-temperature resistance capability, combined with its chemical and radiation resistance properties, ensures the product stability and reliability of PEEK cable ties in high-temperature, corrosive and radiation environments, providing cable fixing and management solutions for these special industries.
Currently, we produce PEEK composite material bearing cages that have been applied in high-speed bearings, with working temperature -70--260℃, high working load, long bushing life, and can work for short periods under oil-free lubrication conditions.
We have been cooperating with a listed electric vehicle company in China for many years. Through years of summary and experience, we found that compared with traditional fuel vehicles, the motor speed of electric vehicles can reach over 20,000rpm, which requires high demands on bearings, including centrifugal force, electrical corrosion, and noise generated by friction. Let's understand the specifics below.
PEEK bearing cages made of composite materials can work normally within 260℃, and the density is only around 1.4.
PEEK bearing cages can isolate current inside and outside the bearing, preventing electrical corrosion.
PEEK composite materials have good self-lubricating properties and low friction coefficient, reducing noise and vibration during bearing operation. Wear resistance performance also extends bearing service life and reduces maintenance costs.
PEEK carbon fiber reinforced bushing products are one of our company's advantageous products. Through years of production, we have found that continuous carbon fiber has higher radial tensile strength than carbon steel, showing very high strength. At the same time, PEEK carbon fiber reinforced bushings have high corrosion resistance and high wear resistance. We use compression molding process for production.
Before using our PEEK carbon fiber reinforced bushings, Danai Pump Industry found problems such as serious corrosion of chemical pumps, particle grinding shaft issues in liquid media, and short replacement cycles for bushing components. After cooperating with us, Dalian Allstar, all the above problems were solved. Although short-term costs increased, from a long-term perspective, production maintenance costs were reduced and benefits were increased.
Since the company's establishment in 2008, we have cooperated deeply with Dalian University of Technology, and PEEK special pump materials are one of the products of our deep cooperation.
The pump special materials we developed have higher strength and longer service life than ordinary products circulating in the market. Compared to metal seals, PEEK pump special materials have smaller clearances, reducing waste and saving costs. The water guide bearings we developed can dry run for 3 minutes, providing users with sufficient processing time, and are very corrosion-resistant, non-oil swelling, non-water absorbing, with design clearances that can be reduced to half of that of nylon bearings.
| Minimum Running Clearance | |||
|---|---|---|---|
| Clearance Part Rotating Component Diameter (mm) | Metal Minimum Clearance (mm) | Composite Material Recommended Clearance (mm) | Composite Material Minimum Clearance (mm) |
| 90 ~ 99.99 | 0.35 | 0.20 | 0.15 |
| 100 ~ 114.99 | 0.38 | 0.20 | 0.15 |
| 115 ~ 124.99 | 0.40 | 0.20 | 0.15 |
| 125 ~ 149.99 | 0.43 | 0.22 | 0.16 |
| 150 ~ 174.99 | 0.45 | 0.23 | 0.18 |
| 175 ~ 199.99 | 0.48 | 0.25 | 0.20 |
| 200 ~ 224.99 | 0.50 | 0.27 | 0.23 |
| 225 ~ 249.99 | 0.53 | 0.32 | 0.26 |
| Because composite materials have smaller coefficients of thermal expansion, the design clearance can be appropriately reduced compared to metal sealing rings. | |||
| Design clearance should comprehensively consider factors such as temperature, corrosion resistance, pump drawing, thermal expansion data, and medium granularity. | |||
| The recommended and minimum clearance positions of composite materials are for reference only. | |||
