A poliéteretercetona está entre os termoplásticos de alto rendimento graças ao seu elevado ponto de fusão de 343 °C e à sua temperatura máxima de funcionamento contínuo de 260 °C. A sua estrutura química particular torna o PEEK bastante estável contra danos térmicos e químicos e permite a sua utilização no interior do corpo. Em caso de incêndio, o desenvolvimento de fumo do PEEK é o mais baixo de todos os termoplásticos; o material é, portanto, utilizado na aviação. ARKPEEK é um filamento experimental com uma temperatura de processamento de 375 °C na câmara aquecida (180 °C). O material é especificamente apto para uso em impressoras 3D.
Material Grade
ARKPEEK-1000: 100%PEEK
A high performance thermoplastic, PolyEtherEtherKetone. It is semi- crystalline and offers high- strength and stiffness as well as high-heat resistance. Also, as it is chemically resistant to aggressive environments, it is suitable for sterilisation for medical and food contact applications.
● Similar strength to low-grade alloys
● Flame retardant, UL94-V0
● High impact & wear resistance
● Semi-crystalline structure providing outstanding mechanical and thermal properties
● Very high chemical resistance (after annealing)
● Can be used up to 260°C/500F (after annealing)
ARKPEEK-CF30: 30% Carbon Fiber + 70% PEEK
A high-performance thermoplastic, PolyEtherEtherKetone (PEEK), reinforced with Carbon-Fiber. It offers high stiffness and high-heat resistance.
