2023 Chinaplas Rubber and Plastics Exhibition PEEK, PI, PPSU New Products Sharing
With the upgrading and transformation of China’s manufacturing industry, the demand for new materials and advanced technologies will continue to rise. Junhua has made great achievements in the 2023Chinaplas exhibition, and has seen the endless new products of PEEK, PI, and PPSU. Here, we will share with you some of the gains of special plastics! 1. PEEK material related products No.01, new energy vehicle flat wire motor PEEK flat wire New energy electric vehicles are driven by electricity, and electricity safety is particularly important. Choosing excellent materials is the key to ensuring the safety of new energy vehicles. PEEK (polyetheretherketone) material can be said to be a “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 other characteristics. It is particularly suitable for manufacturing long-lasting and durable important components, 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, bearings and gear parts, and is gradually replacing traditional metal materials such as aluminum, titanium and steel in some places. PEEK is resistant to corona, 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 preferred materials for new energy vehicle motors. No.02, Medical Implant Grade PEEK Material As the name suggests, PEEK materials that can be used for the preparation of “implanted 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, 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 such as oral implants and traumatic bone plates. In addition to meeting the biosafety of ordinary medical-grade PEEK, implantable 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 the various test requirements of YY/T 0660-2008 and obtained a third-party test report.

Supercapacitors, dielectrics for printing templates and insulation layers for electric vehicle batteries No.5, PEEK prepreg Co-woven 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 co-woven molding technology is that the glue content is easy to control, and a material product with uniform fiber impregnation, high dimensional stability and complex shape can be obtained.
