Product Detail delrin

 Acetal is a high-performance engineering thermoplastic known for its dimensional stability, low friction, and excellent machinability. It is used in tight-tolerance, high-precision components where mechanical strength and rigidity are essential. Common forms include Delrin® (a homopolymer by DuPont) and generic copolymers, available in sheet and rod stock for CNC machining and custom fabrication. 

Key Properties

• Density: ~1.41 g/cm³
• Working Temperature: -40°C to +100°C continuous
• Tensile Strength: ~9,500–10,500 psi
• Coefficient of Friction: ~0.2
• Moisture Absorption: Very low (~0.2%)
• Electrical Insulation: Excellent
• FDA/NSF compliant grades available

Common Applications

• Precision gears, bearings, bushings
• Wear strips and slide pads
• Valve components and manifolds
• Jigs, fixtures, and high-load spacers
• Food processing components (pulleys, guides)
• Medical and laboratory equipment parts
   

Advantages

• Exceptional dimensional stability and low water absorption, making it ideal for tight tolerances
• Very low friction — suitable for unlubricated, moving applications
• Excellent machinability — yields smooth finishes and sharp tolerances
• Strong mechanical properties with good stiffness and hardness
• Chemically resistant to fuels, solvents, and weak acids
• Electrically insulating with low dielectric loss
• Copolymer types are more resistant to hydrolysis and chemicals than homopolymer
