Xytrex range of high performance polymers
XYTREX® products have been developed to offer better efficiency and reliability to pump systems, valves and compressors. They are made of high performance polymers reinforced with specific fillers for applications subject to shock and vibration.
High performance materials for pump and valve industry
With more than 50 years experience, 3P has served the pump and valve industry by supplying components made out of specially formulated fluoropolymers (PTFE, PCTFE, PFA, FEP, etc.) and high performance polymers (PEEK, PEI).
Xytrex® is a range of thermoplastic materials with wide applications in fluid handling systems, based on this experience.
3P has strongly invested in developing its Xytrex® range. New solutions are regularly offered. As a result, more and more pumps, valves and compressors are switching from metallic parts to XYTREX® materials.
Xytrex® materials are more and more used in refining and petrochemical plants. Some Xytrex® polymer materials are listed in the API 610 11th edition.
This range is available as parts or as basic shapes mainly for pump bearings and valve seats in petrochemical industry.
Composite and compounds with unique properties
In addition to the material know-how, the process plays an important part in reaching the desired properties. For example, special processes developed by 3P allow the use of cryogenic virgin PEEK or low permeation PEEK.
Most remarkable properties offered in the Xytrex® range are:
- Excellent wear & friction characteristics
- Exceptional corrosion resistance
- Abrasion resistance to handle service with solids
- Unrivalled mechanical properties at elevated temperatures
- Damping properties
- Unmatched anti-galling properties
Each material can work for specific applications, operating as static and/or dynamic components.
Here are some examples of the most widespread materials
Compound for optimum wear resistance
X451 is based on PEEK matrix with carbon fibers which enhance the compressive strength and stiffness. It offers the best choice for competitive wear resistance at high loads.
X459 is a lubricated version of carbon-PEEK X451. Its improved coefficient of friction suits this solution for extended dry running applications.
Material for high temperature
X450 is a virgin PEEK solution. Its mechanical strength is essential for high temperature applications, with good chemical resistance.
Low permeation compound
X4502 is a high sealing grade. Based on PEEK matrix with proprietary fillers, the tuned transformation process allows fine control of the microporosity. Its low permeation properties make it irreplaceable for critical leak controls, where standard PEEK solution keep leaking.
Materials for cryogenic applications
For cryogenic applications, you have now the choice between 2 solutions optimized whether for pressure or medium.
X860 offers enhanced stability and resistance to cracking thanks to a post-treatment.
Compounds for soft mating surfaces
A-50F is a proprietary PTFE-based compound. It is designed for the most demanding applications. A-50F demonstrates low wear rates in dry applications. It wears approximately half as much as carbon graphite-filled PTFE. It is non abrasive and therefore recommended against soft mating surfaces like aluminium.
Large chemical resistance
X751 is based on PFA with carbon fibers for reinforced mechanical properties and excellent dimensional stability. With its large chemical resistance, it fits any low to moderate radial load applications from -50 °C to 150 °C.
It allows high vibration reduction at commissioning and easily replaces rubber bearings in vertical pumps with low pressure.
Composite with high wear resistance and high load resistance
XC®2 is a high performance composite made of continuous carbon fibers, manufactured by tape winding. It essentially replaces metals thanks to high strength, high wear resistance and low friction. XC®2 mechanical resistance is 3 times higher than stainless steel. It is then an excellent sacrificial part.XC®2-L is a lubricated version of continuous carbon XC®2. It is then an excellent sacrificial part.
XC®2-P is a high performance composite made of continuous and oriented carbon fibers. Its axial load capability makes it ideal for axial thrust and face loading applications. It offers shock & impact resistance and high dimensional stability.
