1. PEEK material related products

No.01, PEEK flat wire for flat wire motor of new energy vehicle

New energy electric vehicles are powered by electricity, so electricity safety is particularly important. Selecting excellent materials is the key to ensuring the safety of new energy vehicles.

PEEK (polyetheretherketone) material can be said to be the “hexagonal warrior” in the field of special engineering materials because it has various excellent properties, such as corrosion resistance, wear resistance, high strength, low density and so on.

It is particularly suitable for manufacturing long-lasting and important parts, which can extend the service life of parts, reduce maintenance frequency and reduce costs. PEEK is becoming increasingly popular in the fields of new energy electric vehicle structures and bearing and gear parts, and is gradually replacing traditional metal materials such as aluminum, titanium and steel in some places.

PEEK is corona-resistant, has a low dielectric constant, is resistant to bending and chemicals (including lubricating oil, ATF oil, impregnation paint, epoxy resin paint), and is resistant to high and low temperature conditions. It is one of the best choices for new energy vehicle motors.

No.02, Medical implant grade PEEK material

As the name suggests, PEEK materials that can be used to prepare “implantable devices” are called implant-grade PEEK. This type of material is commonly used in orthopedic implant consumables (such as intervertebral fusion devices, ligament repair anchors, joint interface screws), neurosurgery patches (such as artificial skulls and maxillofacial bones), and cardiovascular products (such as heart valves, pacemaker housings, etc.).

In recent years, some manufacturers are using modified PEEK materials for the preparation of products with high mechanical properties requirements such as oral implants and traumatic bone plates. In addition to meeting the biosafety of ordinary medical-grade PEEK, implant-grade PEEK should also meet more stringent biocompatibility requirements, such as systemic toxicity, genotoxicity, carcinogenicity, blood compatibility, and implantation reactions, and must also comply with the requirements of “YY/T 0660 Standard Specification for Polyetheretherketone (PEEK) Polymers for Surgical Implants”.

The AKSOPEEK series of implantable PEEK materials registered by Junhua Company have passed all test requirements of YY/T 0660-2008 and obtained third-party test reports.

No.5, PEEK prepreg

Mixed molding is a traditional molding technology for continuous CF/PEEK prepreg. PEEK resin is first processed into fibers, and then mixed with carbon fibers into hollow, strip, ribbon, three-dimensional or two-dimensional geometric fabrics. PEEK is melted by hot pressing to achieve fiber impregnation. The advantage of mixed molding technology is that the glue content is easy to control, and materials with uniform fiber impregnation, high dimensional stability and complex shapes can be obtained.
