Polyetherimide has recently joined the BIEGLO portfolio. Our sales portfolio for PEI contains rods and sheets from 8mm to 100mm diameter. As well as, PEI thin films below 1mm thickness. The maximum width is 1200mm for sheets and film. Polyetherimide is an amorphous thermoplastic and part of the polyimide family. It has excellent dimensional accuracy over a wide temperature range and has low thermal expansion. PEI is naturally flame retardant and has a fire rating of UL94 V-0. The most common applications of PEI are in the food and beverage industry, pharmaceutical and electronics industry as well as precision engineering.

Polyamide-imide (PAI), also known as the brand Torlon® comes in different grades and different shapes. PAI is known to be the highest performing meltable thermoplastic in terms of temperature resistance, chemical resistance and mechanical stress. BIEGLO offers PAI semi finished products, such as rods, tubes and sheets from different PAI types: Torlon® 4203; 4301; 4275; 4435; 4645; 5030 (30% GF); 7130 (30% CF). Its mechanical strength at 205°C outperforms many engineering plastics at room temperature. The unique performance of Polyamide-imide (PAI) is the result of being transformed from a thermoplastic to a cross-linked thermoset during an extended curing process. Our PAI is processed by experienced engineers and offeres the best possible values a PAI product can have. It is suitable for many applications, such as gears, rollers, plasma chamber hardware and wafer contact fixtures.

BIEGLO offers PEEK micro-mold parts up to 12mm in the largest dimension. Our smallest part to date is roughly 800µm x 300µm x 380µm and the thin wall section near 0.1mm. The feature aspect ratios around 6:1. In addition, the part volume 0.08 cm3 or less, the gate size as small as Ø0.1mm and the ejector pins as small as Ø 0.254mm. PEEK micro-mold parts must have a gate and ejection location consideration and the material selection can greatly affect the fill and definition of features.

The Dexnyl PEEK filaments of BIEGLO is a high performance product made by melt spinning. Semicrystalline PEEK has high tensile strength, it is exceptionally resistant to chemicals and can withstand extreme temperatures. These features ensure a longer product life, lower maintenance costs, less machine downtime and wider material design options compared to steel or aluminum parts. PEEK filaments can be used very well for 3D printing. Printing with PEEK requires 360 ° C to 380 ° C. So far, only specially modified 3D printers are able to achieve this heat. Sliced ​​woven and/or unidirectional fibers significantly reinforce matrix material and are a popular additive for composites. PEEK filaments are also used on musical instruments, rackets and wide or narrow woven straps, filtration mesh fabrics and sewing threads. Due to their low weight and high temperature resistance, PEEK filaments are popular in many other industies, such as automotive and aerospace industries.

The Dexnyl PEEK tubes can be an intelligent solution for round and hollow pieces. They are mostly extruded or compression molded. But BIEGLO GmbH offers also injection molded PEEK tubes and spin casting PEEK tubes in long and short length and special thin wall tubes. Parts made-up of our PEEK offer excellent hydrolysis and electrical insulation. PEEK is the ideal replacement for metal and other plastics due to its high temperature resistance of up to 240°C , excellent chemical and wear resistance. Our range of PEEK tubes starts with 25mm up to 1.480mm (external diameter); 20mm up 1.300mm (internal diameter). Our PEEK tubes are also available made of compounded PEEK.

BIEGLO offers high temperature resistant and flame retardant fibers. The application is similiar to meta-aramid, but PI fibers have its own advantages. The long-term service temperature is 260℃. The decomposition temperature is 560℃. The LOI is 38%, it means it is non-flameble fiber. The Dexnyl Polyimide fibers are applicable in many products, but they are used best in niche-applications with extreme standards for the material: 1- FR Protective clothing: e.g. military fligth clothing, flame resistand underwear, firefighter uniform etc. 2- High temperature filtration and industrial insulation: e.g. dedusting filtration for cement factories, steel or powder plants, air filtration for painting area operated at more than 300°C . 3- Composite material: taking advantage of insulation, flame retardance and high emperature resistance, chopped fiber can be used as reinforced material.

When it comes to filter material, there are a few points to consider. The filter material should have a large surface area. This ensures a good exchange rate between exhaust air and filter material and provides sufficient space for microorganisms to colonise. The filter material must be designed in such a way that it has a good water holding capacity. The colonised microorganisms are only viable in a moist environment. In general, different filter materials are used in one batch. The reason for this it ensures both a good stability of the filter bed and a larger surface. In addition, the added microorganisms must be sufficiently supplied with inorganic nutrients and trace elements, unless this is provided by the composition of the exhaust air. The temperature inside the biofilter system plays a decisive role as well. Temperatures between 5 °C and 40 °C are favourable for the microorganisms to work properly.
