PEEK (Polyether ether ketone ) is a semi-crystalline thermoplastic material, which has very excellent physical and mechanical properties, and could replace the traditional materials such as metal, ceramic in many fields.
PEEK ultrafine powder and PESU ultrafine powder have excellent high temperature resistance, wear resistance, corrosion resistance and other characteristics. and are well used in non-stick pan coatings, food processing protection, automobile chassis protection, chemical equipment corrosion protection and other fields.
PEEK material is ideal for aerospace lightweight materials, Its light weight, combined with excellent high strength, fire resistance, flame retardant and non-toxic properties, can achieve aerospace weight reduction and cost reduction goals.
PEEK | PEEK Specification |
SOOG | Semi-crystalline polymer materials can be used as high-temperature structural materials and electrical insulation materials, with rigidity and flexibility, especially the fatigue resistance under alternating stress is very prominent, comparable to alloy materials |
SOOGL20 | The composite reinforced material with 20% glass fiber has better mechanical properties |
SOOGL30 | With 30% glass fiber composite preparation of reinforcement material, has excellent insulation, high temperature resistance and corrosion resistance |
SOOCA30 | The composite reinforced material with 30% carbon fiber has better mechanical properties |
