PEEK - Bülte's New Product Range 

For more than 60 years, Bülte has been supporting all industry sectors to meet their needs for plastic protection and fasteners. Established in Germany, England, and France, the international profile family-owned company launches this autumn a new range of products: an organic thermoplastic polymer used in engineering applications, PEEK. 

Considered as one of the top-of-the-range plastics, PEEK is a thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures (oils, hydrocarbures). 

Because of its robustness, PEEK is used to fabricate items used in demanding applications, including bearings, piston parts, pumps, compressor plate valves, and electrical cable insulation. Due to its low flammability (UL 94), it is one of the few plastics compatible with ultra-high vacuum applications, which makes it suitable for many types of industries. PEEK is also considered as an advanced biomaterial used in medical implants. 

It also has a lower density than metal, which makes it an excellent substitute when weight is a limiting factor in the final product. 

All these properties make it a material of choice in the manufacture of technical and/or electrical parts. 

It is therefore highly recommended for use in high-tech industries: 

Energy (Oil, Nuclear), Medical & Pharmaceutical (replacing glass, stainless steel or other metals), Chemical, Automotive (manufacturing of steering elements, clutch or brake components, etc.), Electronic industry (insulators, connectors and supports). 

Bülte's product range in PEEK material includes: 

- Washers ˜ DIN 125 / EN ISO 7089 / DIN 34815 from M4 to M12 
- Hex socket head screws ˜ DIN 912 from M4 to M12 (lengths 10 to 70mm) 
- Hex head screws ˜ DIN 933 from M4 to M12 (lengths 10 to 60mm) 
- Hex nuts ISO 4032 from M4 to M12
