7/23/2023 0 Comments Peek material full formThis makes it ideal for applications that require improved stability, strength, and stiffness at temperatures above 300º F. This unique type of PEEK is reinforced with glass fibers, which significantly reduces its expansion rate and increases the flexural modulus. Virgin PEEK plastic also displays natural abrasion resistance, which is important for heavy-duty applications. Our Standard Virgin Grade PEEK is FDA compliant, which makes it appropriate for use in laboratory and medical environments. Housing starts soared 21.7 in May to 1. Two of the most common varieties of PEEK high performance plastic that Online Plastics offers, include: It is a food-approved, part-crystalline thermoplastic that is particularly well suited to areas where temperatures are. Lumber prices jumped on Tuesday after US housing starts surged by the most in three decades. PEEK sheet and PEEK rod are also soluble in concentrated sulfuric acid at room temperature, although dissolution can take a very long time unless the polymer is in a form with a high surface-area-to-volume ratio, such as a fine powder or thin film.ĭepending on your specific application needs, PEEK plastic is available in a variety of formats and material options. It can also be susceptible to halogens and strong Brønsted and Lewis acids and other halogenated compounds and aliphatic hydrocarbons at high temperatures. A composite material (and compound), then, comprises a polymer matrix, additive in the form of a powder, flakes, or fibers, and an interface between them. PEEK has a glass transition temperature of around 143 ☌ (289 ☏) and melts around 343 ☌ (662 ☏). For implantable materials, such functionality may include modulus matching to bone, or the ability to provide enhanced radiographic imaging. In more scientific terms, the Young's modulus is 3.6 GPa and its tensile strength is 90 to 100 MPa. PEEK is also highly resistant to thermal degradation and attacks from organic and aqueous environments, with a high resistance to biodegradation. The thermal conductivity of the material also increases linearly when the active temperature is between room and solidus temperature. Some grades have a useful operating temperature of up to 250 ☌ (482 ☏). The processing conditions used to mold PEEK can influence the crystallinity and enhance the mechanical properties of the material. When it comes to PEEK machining, this process forms components like bearings, electrical components, filters, and more.PEEK plastic is a semicrystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained at high temperatures. You’ll find CNC machining also works with metals, wood, and more. An engineer writes the directions and feeds those to the computer, the computer reads the information, and then the computer directs the machinery with complete accuracy.ĬNC machining is used with all types of materials, not just PEEK plastic. Think of PEEK CNC machining as a chain reaction. These machines are guided by a computer that feeds them specific instructions to shape, bend, turn, and form the plastic material. PEEK CNC machining is a common method for forming plastic parts that are crafted to exact specifications.ĬNC Machining stands for “computer numerical control” machines like mills and lathes. In order to form products out of PEEK plastic, different machining processes need to be enacted. Processing PEEK Plastic | PEEK CNC Machining When exposed to different elements and materials, PEEK will remain constant and non-reactive. This document establishes a system of designation for polyetheretherketone (PEEK) moulding and extrusion materials which can be used as the basis for. This material is also chemically inert, which refers to a lack of chemical reactions. Lightweight and inert: PEEK plastic is lightweight which makes PEEK CNC machining a more seamless process. Unlike other plastics, PEEK will maintain its durable form after undergoing stress. It is also creep resistant, which refers to a material’s resistance to slowly deforming over repeated exposure to stress. Stress and creep resistant: PEEK plastic is resistant to various types of stress making it ideal in industries like aerospace and oil and gas. Materials with low hydrolysis resistance break or dissolve easily when exposed to water. PEEK plastic also has high hydrolysis resistance, which is essentially the material’s reaction to water. This will help you make the right decision as to when and how to use PEEK in your application.Ĭhemical and hydrolysis resistance: PEEK plastic is resistant to many harsh chemicals, which means it can undergo difficult applications without bending or decaying. In order to understand “What is PEEK Plastic?” it is important to understand its most important properties.
