Friction and wear characteristics of PEEK
Junhua PEEK Technical Data: Introduction to the Self-lubrication, Friction and Wear Characteristics of PEEK 1. Friction is the interaction between contacting surfaces when they move relative to each other under the action of external forces. When observing the surface of a material that looks very smooth under a microscope, you can see obvious bumps and depressions. Therefore, if two materials are in contact and move relative to each other, the rough granules on the surfaces of the two materials will collide with each other, and the disappearance of the rough granules can be defined as wear. 2. PEEK has outstanding sliding properties among all plastics. It can provide excellent wear resistance under various temperatures, pressures and relatively rough contact surfaces….

PEEK flame retardant properties
Brief introduction to PEEK’s flame retardant, low smoke and low toxic gas emission characteristics PEEK is difficult to burn in general situations. Even when it burns, the amount of smoke and corrosive gas produced is very small. PEEK has the advantages of flame retardancy, low smoke and low toxic gas emission. The details are as follows: 1. Flame retardancy: The flammability of a material is the ability to sustain combustion after obtaining high energy from a mixture of oxygen and nitrogen. The recognized standard for measuring flammability is UL94, which is to ignite a vertical sample of a predetermined shape and then measure the time it takes for the material to automatically extinguish. The test result for PEEK is V-0,…

PEEK Corrosion Resistance
1. PEEK can tolerate almost any chemical except fuming concentrated sulfuric acid, and it can maintain good chemical stability even at higher temperatures. It has strong resistance to chemical corrosion and is usually used to manufacture parts that work in harsh environmental conditions or need to withstand frequent disinfection (such as chemical storage tanks and medical devices that need to be disinfected with strong oxidant hydrogen peroxide). 2. Although PEEK polymer has been widely regarded as a material that can withstand extremely strong chemical corrosion, of course, whether PEEK can withstand a certain corrosive medium is also related to the crystallinity of the PEEK parts, the residual internal stress, and the temperature and concentration of the medium in contact with…

Introduction to PEEK’s hydrolysis resistance
Company technical data: PEEK has outstanding hydrolysis resistance 1. PEEK has the best resistance to hot water and steam among all engineering plastics. PEEK polymer and its composite products (i.e., modified by glass fiber, carbon fiber, graphite, PTFE, etc.) can resist chemical damage caused by water or high-pressure steam, can be used continuously under hot water and high-pressure steam conditions, and still maintain good mechanical properties. 2. PEEK’s good hydrolysis resistance enables PEEK and its composite products to withstand repeated high-temperature and high-pressure steam sterilization, which other thermoplastics cannot withstand for a long time, so it has been successfully used in harsh areas such as medical equipment. 3. Mechanical properties change test data of PEEK and its composite materials under…
