1、 Material overview
Peek and PI are high-performance materials synthesized by British wiggs company and DuPont company with invention patents respectively. Peek and PI in high-performance polymers have excellent comprehensive properties that can not be compared with other general-purpose plastics, and have excellent properties suitable for various harsh environments. They have been successfully widely used in aerospace, automobile, electronic semiconductor, etc Mechanical and electrical industry in various demanding occasions. It is the preferred material for users to develop new products and improve the service life and reliability of products.
2、 Features and advantages
★High temperature resistance
The long-term use temperature of UL certification is 260 ℃. Even when the temperature is as high as 300 ℃, it can still maintain good mechanical properties
★Wear resistance
Peek polymer and its composites have good wear resistance in many extremely harsh applications such as high temperature, high load and strong corrosion.
★Self lubricating
With low friction coefficient, it can realize oil-free lubrication, and can work in oil, water, steam, weak acid and alkali medium for a long time.
★Corrosion resistance
It is insoluble in common solvents and has good corrosion resistance to various organic and inorganic chemical reagents.
★High strength
It has good mechanical strength in plastics. It also has high rigidity and surface hardness.
★Easy to process
The parts can be directly processed by injection molding process. It can be used for turning, milling, drilling, tapping, bonding and ultrasonic welding.
★Hydrolysis resistant
The peek products can still work for thousands of hours without obvious performance degradation when they are soaked in steam with temperature over 250 ℃ or high pressure water.
★Fire retardant
The flammability grade of 1.45 mm thick peek sample is UL94 V-0 without any additives.
★Low smoke and non-toxic
When burning, the amount of smoke and poison gas is very low.
★Electrical performance
In a wide temperature and frequency range, it can still maintain stable and excellent electrical performance.
★Radiation resistance
It has strong resistance to high dose γ The performance of radiation and mechanical properties can be completely retained, which can be used as radiation resistant parts in nuclear equipment.
★Stable size
Shortcoming:
The injection process is harsh and the machining process is demanding.
The strength is lower than that of metal materials.
