Polyimide PI sheet

GuangZhou Ideal has been making the polyetheretherketone PEEK part product for more than fourteen years, so we’ve got a lot of experience under our belt. Let me quickly break down PEEK material for you: basically, it’s a high-performance specialty plastic. Its molecular chain is packed with benzene rings, and those rings are held together strongly by ketone and ether groups. All those benzene rings are what give PEEK such great heat resistance and mechanical strength.Inside, the material is semi-crystalline—meaning it’s made up of both amorphous and crystalline areas at the same time. Usually, the products we make have a crystallinity between 20% and 35%. But depending on the process we use, we can adjust that. We can go as low as completely amorphous (0%), or push it higher—up to around 48%.

Here at GuangZhou Ideal, we use professional CNC machines to produce CNC PEEK part. The PEEK material we work with is a special engineering plastic with some really standout properties. If you break it down to the molecular level, its structure is basically a repeating pattern of "benzene ring – ketone bond – benzene ring – ether bond – benzene ring – ether bond." That setup is pretty clever—the rigid benzene rings act like "steel bars," giving the material its strength and heat resistance. Meanwhile, the flexible ether and ketone bonds work like "springs," allowing the chains to move just enough so the material stays workable and tough under impact.

PEEK plates is a top-tier PEEK profile. PEEK, short for polyetheretherketone, is a semi-crystalline thermoplastic with some really impressive features. It’s produced through a condensation reaction between 4,4'-difluorobenzophenone and hydroquinone, using alkali metal carbonate as a catalyst and diphenyl sulfone as the solvent. As a standout member of the polyaryletherketone (PAEK) family, PEEK ranks among the highest-performing polymer materials out there—often called the “king of resins.” Not only is it strong, chemically stable, and lightweight, but it’s also highly biocompatible, making it a great high-performance plastic alternative to metal.

PEEK Bolts, also known as PEEK Screws or polyetheretherketone fasteners, are non-metallic fasteners made from PEEK (polyetheretherketone) base stock. Compared with metal bolts, they provide excellent chemical resistance, electrical insulation, non-magnetic performance and low weight for equipment assembly in harsh operating environments. Available in virgin PEEK and reinforced grades, PEEK Bolts support different requirements for strength, wear resistance, temperature resistance and dimensional stability.

So basically, Glass Fiber Filled PEEK Rods is all about making PEEK even better by mixing in glass fiber. PEEK itself is already a high-performance engineering plastic with a special molecular structure—think alternating ether bonds, aromatic rings, and carbonyl groups. Since its molecular chain is made entirely of aromatic rings, it’s naturally super heat-resistant. It’s also really stiff and has great mechanical properties to begin with. When you add glass fiber into the mix, those properties get even stronger.

Vespel SP-21 Plates from Ideal Plastic factory are high-performance black polyimide (PI) composite sheets modified with 15% graphite filler. Different from high-graphite SP-22 grades, SP-21 balances ultra-high mechanical strength, stable electrical performance and excellent self-lubricating wear resistance while retaining full extreme temperature resistance of pure PI materials.
1. ultra-low water absorption
