PEK for Metal Replacement and Applications Requiring the Highest Heat Resistance
NPE 2024: Polyplastics’ new Sarpek polyetherketone (PEK) is said to be an advancement over PEEK.
A new PEK (polyetherketone) for metal replacement and applications requiring the highest heat resistance of any injection moldable resin without requiring post-curing is the latest addition to the portfolio of engineering thermoplastics from Polyplastics. Sarpek PEK has a melting point of 698° F/370°C and a glass transition temperature of 311°F/ 155°C, and is available in unreinforced grades along with 30% glass-filled and 30% carbon fiber-filled grades.
New Sarpek PEK is being positioned at the top of Polyplastics’ portfolio of crystalline polymers. It is said to be an advancement over PEEK (polyetheretherketone) that delivers a high crystallization rate and high molding efficiency. This PEK also features higher heat resistance than PEEK, with durability and superior strength to replace metals in harsh environments where other crystalline plastics fail and metals are heavy and noisy.
