Guide to PEEK and PPS: A blog about the different kinds of thermoplastic polyesters
We received a lot of questions from customers regarding PEEK plastic, PPS, and PPS GF40 material. Many of them do not know the difference and even some suppliers claim that their material is PEEK when it is actually different materials. In order to give clear answers to those questions, we take this opportunity to explain in this article the differences between PEEK plastic, PPS, and PPS GF40 material.
As you know, thermoplastic polyesters are a type of plastic that was developed in the 1950s. Although it first saw use as a synthetic replacement for ivory in billiard balls and piano keys, this material has since been used in many other applications due to its unique properties. While it may seem that PEEK and PPS thermoplastic polyesters are very much like–the difference between the two is not only significant but also significant enough to determine their uses.
Polyether ether ketone -PEEK
Polyether ether ketone (PEEK) is a technically advanced thermoplastic. What makes PEEK different from other thermoplastics like nylon or polypropylene, is its crystalline structure. This type of structure gives the material high tensile strength and resistance to chemicals, which make it a good choice for medical applications where it can be used in surgical equipment, implants, and even dental floss. PEEK is also an excellent electrical insulator and has thermal stability of up to 446°F (230°C).
PEEK is a polymer with high glass transition temperature and excellent thermal stability. It is a high-performance engineering plastic that can be exposed to both high heat and high stress without compromising mechanical properties.
Keward PEEK tube can be used for custom projects like structural parts on bicycles or anywhere you want an extremely strong material with high heat resistance. We sell tubes from 40mm to 600mm in diameter and up to 3 meters long.
Polyphenylene Sulfide -PPS
Polyphenylene sulfide (PPS) is a type of thermoplastic polymer that exhibits high-temperature stability and resistance to chemical attack, as well as excellent mechanical strength and dimensional stability. It is commonly used in the automotive industry as an electrical insulator, due to its high electrical resistivity and good thermal stability.
PPS plastic rod is a type of plastic sheet that can be used in a variety of different ways. It’s commonly sold as thermal plastic, so it’s available in black, white, and clear. Because it’s such a versatile product, it can be used in a number of different applications.
PPS is also used in a number of applications requiring strength at high temperatures and resistance to chemicals. It’s often chosen for its higher mechanical and thermal stability over other plastics such as PTFE (polytetrafluoroethylene) or PP (polypropylene). In fact, it’s one of the few plastics that can be extruded into fibers or films at temperatures above 300 degrees Celsius because of its high melting point of 280-300 degrees Celsius (536-572 degrees Fahrenheit).
Polyphenylene Sulfide glass filled — PPS GF40
PPS GF40 Material is Polyphenylene sulfide, one type of a large class of polymers called polysulfides. It is a thermoplastic material that can be injection molded, extruded, and thermoformed. It is used in industrial and consumer goods where a combination of good mechanical properties (low density and high strength) with excellent chemical resistance at high temperatures is required.
PPS GF40 Sheet is a material that is used for building and construction purposes. It is manufactured in different thicknesses and widths. With the help of the PPS GF40 Sheet, you can create a huge variety of products such as fire-resistant doors, windows, kitchens, etc. This product has been popular since it was launched in the market.
As you may already know, PEEK has high heat resistance, good dimensional stability or creep resistance, and excellent mechanical properties. And the feature that PPS and PEEK have in common is that they are thermoplastic polyesters that can be used at high temperatures. Therefore when needing applications of high temperature, good thermal resistance, and performance of chemical corrosion resistance, it’s your best choice.
