Even if the Dr. Dietrich Müller GmbH machines in the composites production area with a focus on thermoset materials, thermoplastic materials are also processed.
Polyamid PA 46
PA 46 is mainly used in the higher temperature range, where the stiffness, tracking resistance, permanent heat resistance and fatigue resistance of PA 6, PA 66, POM and PET are no longer sufficient. PA 46 is therefore suitable for high-quality technical applications in apparatus construction, in electrical engineering and in the automotive industry.
Polyamid PA 6
Very tough, even in the cold. Hart. High damping capacity. Technical parts such as gears, pinions, screws, nuts, bearings, seals, coupling parts, guide parts, pump parts, fittings, housings, bobbins, etc.
Polyamid PA 66
The polyamide with great hardness, rigidity, abrasion resistance and dimensional stability in the heat. Preferred polyamide for highly stressed and heat-stressed parts in electrical engineering, in machine, vehicle and apparatus construction.
Polyamide PA 66 GF 30 30% glass fibers
These 30% glass fiber reinforced polyamide types have – while maintaining a very high wear resistance – higher strength, rigidity and dimensional stability than unreinforced PA 6 and PA 66. They also allow use at higher service temperatures.
Polyamid PA 6 G
blue / natural / black
Thick-walled molded parts, semi-finished products with high unit weights. Overmolding of inserts (rollers, cores) and large molded parts of all kinds.
Polyamid PA 11
Water fittings, underwater bearings, seals, housings, fans, insulating parts, parts for textile machines and household appliances, gears, sliding pieces and guides. Very low water absorption.
Polyamid PA 12
Maintenance-free bearing and gear parts under water, insulating parts, seals, gears, parts for pumps and household appliances. Applications in the electrical sector, slightly lower water absorption than PA 11.
Is especially used where high strength over a temperature range (-190 ° C … + 260 ° C), high impact strength and very good electrical properties are required. Further characteristics are good chemical resistance, flame retardancy and high heat resistance.
The mechanical properties of PBT are not quite as favorable as those of partially crystalline PET, but it is much easier to process.
PBT GF 30 30% glass fibers
PBT GF is a partially crystalline construction thermoplastic reinforced with glass fibers with very high rigidity and strength, with very good insulation properties and versatile applicability.
Hard, stiff, very good impact method in a wide temperature range (up to -100 ° C). High dimensional stability when heated, crystal clear with a slightly yellowish color. Low water absorption, weather-resistant, physiologically harmless.
Peek is a deeply crystalline, easily processable thermoplastic, which is characterized by high tensile and flexural strength, impact strength and consistently good electrical properties from 0 ° C-220 ° C, as well as good sliding and wear behavior and low flammability.
PEEK BG carbon fibers,
The addition of carbon fibers, PTFE, and graphite results in a material with higher mechanical strength, a low coefficient of sliding friction, and improved abrasion resistance. Due to the excellent tribological properties of PEEK BG, this material is particularly suitable for plain bearing applications.
Tough, flexible to stiff depending on the crystallinity (density). Waxy surface. Excellent dielectric properties. Good resistance to solvents, acids and alkalis. Physiologically harmless. Low water absorption, not aroma-proof. Versatile in use. Easily processable by all methods. Easy to use for cutting, easy to color, flammable. The materials have excellent sliding properties, the high molecular weight PE 1000 can be used up to -260 ° C, and there is very little abrasion.
A material that has a very high strength and high heat resistance and allows use at high temperatures. Furthermore, it is characterized by consistently good electrical properties over a wide frequency and temperature range, high dielectric strength, high flame resistance, high resistance to gamma rays and good machinability.
Linear, saturated polyesters are thermoplastics that are used where good dimensional stability, high creep strength and good sliding and wear behavior are required. Semi-crystalline PET has high hardness, rigidity, strength and toughness even at lower temperatures; in the amorphous state, hardness and rigidity are lower.
Extremely wide temperature range, high resistance to oxidation, UV-stable, low coefficient of expansion, exceptional strength at high temperatures, resistance to stress cracking.
Parts made of PMMA are brilliant and have a crystal clear view. Excellent aging and weather resistance. Good surface hardness. Scratch resistant. Physiologically harmless. High strength. Easily colored.
