Anti-static ESD PEEK sheets not only have excellent mechanical properties but also stable anti-static performance. They can be used for a long time in high-temperature environments without significant changes in performance and resistance

PEEK GF30 Sheet is a structural grade engineering plastic sheet formed by uniformly dispersing 30% short cut glass fibers in a high-performance polyether ether ketone (PEEK) matrix and extruding them at high temperature and high pressure. The mesh reinforcement effect of glass fiber makes the bending modulus of the material reach 11.3 GPa (about 2-3 times that of unreinforced PEEK), and the tensile strength is ≥ 170 MPa. Combined with extremely low creep rate and thermal expansion coefficient, it endows the sheet metal with structural rigidity and long-term load-bearing stability.

Unfilled PEEK Sheet, also known as Natural PEEK Sheet, is engineered for high-purity applications. Made from virgin resin with zero fillers, it offers a continuous service temperature of 260°C, excellent chemical resistance, and superior insulation. Full-size sheets are kept in stock and available for precision cut-to-size processing. Virgin Purity:​ Referred to as Natural PEEK Sheet, this unfilled grade contains no additives, ensuring compliance with medical and semiconductor standards.
High Performance:​ Withstands continuous temperatures up to 260°C while maintaining exceptional chemical resistance and electrical insulation.
Ready to Ship:​ Standard stock sizes are available with custom cutting services to meet your machining requirements.

To 2026, 30% carbon filled PEEK material is currently one of the most outstanding thermoplastic composite materials in terms of performance.
Its temperature resistance and mechanical strength have been significantly improved, with less deformation at high temperatures, making it a reliable precision material with high temperature resistance

Unreinforced polyetherimide (PEI) rods are translucent amber  color, has excellent toughness, naturally exhibit UL-94V0 flame retardancy, and produce very little smoke when burning.

PEI has excellent dimensional stability，even without fiber reinforcement, PEI does not warp. As a non-crystalline plastic, it generates  high temperatures during processing and does not easily deform after cooling, is a suitable plastic rod for high precision machining.

The deformation of glass fiber reinforced PEI material under high temperature and heavy load is very small, enabling it to maintain dimensional stability. It is a material that can well replace metals. It has high rigidity and strength while being very lightweight. It is commonly used in structural load-bearing components in the aerospace and automotive fields.
The interface bonding strength between PEI and glass fibers is extremely high. PEI itself has a highly rigid imide ring structure, and through the filling of glass fibers, it greatly inhibits the thermal motion of molecular chains at high temperatures.

PEEK GF30 rods are engineered to excel in applications requiring maximum dimensional stability under load. By incorporating 30% glass fibers, the material achieves a flexural modulus of 11 GPa, providing the stiffness necessary to support significant weight without deformation.
Unlike unreinforced PEEK, which may exhibit creep under sustained pressure, the glass fiber reinforcement locks the polymer structure in place. This results in exceptional high static load capacity, ensuring that components such as support brackets, insulating mounts, and structural frames remain stable even at elevated temperatures (HDT up to 328°C).

Fiber reinforced PEEK rods have excellent bending strength and modulus, and superior bending resistance. The thermal expansion coefficient and shrinkage rate significantly decrease. Can be used to manufacture precision components that are resistant to high temperatures.
Compared to PEEK GF30, carbon fiber PEEK rods have higher rigidity and tensile strength, lower density, better wear resistance, and faster thermal conductivity
