PEEK in the analytical instruments industry has been very successful application of the instrument to change the channel or switch to a different brand of column material using PEEK tubing and fittings will be very convenient. PEEK tubing is easy to connect, PEEK connectors not only without tools, hand screw can be fixed, and easy to adjust the length of the pipeline outside the cone hoop, convenient and different brands or specifications of the column phase. PEEK tube with inert to most chemical solvents and biological compatibility with other characteristics, can replace stainless steel, PTFE tube for conventional liquid analysis system. PEEK with stainless steel pipes and tubes of different titanium, PEEK tube with toughness, easy interception, PEEK polymer can be used pipe fittings.



Engineering plastic PEEK board with abrasion resistance 

PEEK is a kind of heat-resistant, high performance thermoplastic special engineering plastics. It has good mechanical properties and chemical resistance, abrasion resistance, and hydrolysis resistance properties etc.; It has a light proportion and self-lubricating properties. Due to very good processing properties, it can be filled with carbon fiber and MOS2 etc. To improve lubrication performance and mechanical strength further. 

PEEK engineering plastics have a broad application space related to aviation, machinery, electronics, chemical industry, automobiles, and other high-tech industry, mechanical parts and accessory can be manufactured in stringent requirements, such as gears, bearings, piston rings, supporting ring, sealing ring (letter), valves, and other wear circle. 

The outstanding performance of PEEK material mainly shows in the following aspects: 

1. Heat-resistance 
PEEK has a higher glass transition temperature and melting point (**4º C). It is one of the reasons that it can be a reliable application in the requirement of the heat. Its heat load variable-temperature can be **6º C, continuous use temperature is **0º C. 
2. Mechanical Properties 
PEEK is the plastic that strikes a balance between toughness and rigidity. Especially, it has an excellent fatigue resistance against alternating stress that is the most talented of all plastics, and it can be comparable with alloys. 
3. Self-lubricating 
PEEK has outstanding sliding characteristics in all plastics; It is suitable for stringent requirements for low coefficient of friction and resistance to friction used. Especially, the self-lubricating properties of PEEK will be better if it is modified by carbon fiber and graphite mixed in the proportion of each of them. 
4. Chemical Resistance (corrosion resistance) 
PEEK has excellent chemical resistance. In ordinary chemicals, it can be dissolved or damaged only by concentrated sulfuric acid; Its corrosion resistance is similar to those of steel and nickel. 
5. Flame Retardant 
PEEK is a very stable polymer. The 1.*5mm thick samples can achieve the highest standard of fire retardant without adding any fire retardant. 
6. Stripping Resistance 
PEEK has good stripping resistance; Therefore, it can be made into thin wires or electromagnetic wire coating, and it can be used in harsh conditions. 
7. Fatigue Resistance 
PEEK has the best fatigue resistance among all resins. 
8. Radiation Resistance 
PEEK has a very strong γ Irradiated resistance, which is stronger than the radiation resistance of polystyrene, which is the best one among generic resin. It can be made into high-performance wiring that can still make good insulation capability when γ Irradiation is at doses of ***0Mrad. 
9. Hydrolysis Resistance 
PEEK and its composites will not be affected chemically by water and high-pressure steam. The products that are made from this material will maintain the outstanding characteristics in continuous use in high temperature and high pressure water.
