CNC Machined Nylon (Polyamide)

Good abrasion and wear resistance, Good impact strength and stiffness

Snapshot of Nylon Plastic

Nylon plastic Description
Nylon is a generic designation for a family of synthetic polymers known generically as PA PolyAmides. Nylons (Polyamides) comprise the largest family of engineering plastics with a very wide range of applications. Nylons are generally Strong, Tough and Wear Resistant.
Advantages of Nylon parts
Excellent abrasion resistance, High elongation, Good resistance to fuels, oils and solvents but is affected by acids and strong bases. Good Toughness, High Tensile Strength, High Impact Resistance, Good Dimensional Stability.
Nylon plastic Uses
Ideal for wear applications such as Bearings and Gears, Sporting goods, Fishing line, Automotive parts, Tanks, Engineering parts, Power tools, Intake manifolds.

Further considerations
Nylons are commonly used in textiles, automotive, carpet and sportswear due to their extreme durability and strength. Nylon has better wear-resistance than Acetal, but do not have good moisture resistance which makes it unsuitable to high-humidity.
Limitations
High moisture absorptivity degrades electrical and mechanical properties. Attacked by strong acids, Bases, Oxidizing agents. High Notch sensitivity.

Density (g/cm³)

For a homogeneous object, Density = Mass Divided By Volume. The higher the density, the tighter the particles are packed inside the substance. The Specific Gravity is the ratio of Density of the material to the Density of water at a specified temperature. It is common to use the density of water at 4°C as reference - at this point the density of water is at the highest i.e. 1 g/cm3. So Specific Gravity of less than “1” means that the material will float in water.

Water Absorption-24 Hours (%)

Water absorption is used to determine the amount of water absorbed under specified conditions. Water absorption is expressed as increase in weight percent. Percent Water Absorption = [(Wet weight - Dry weight)/ Dry weight] x 100

Tensile Strength (Mpa)

Tensile strength is a property of a material that measures the force required to pull something to the point where it breaks. Tensile strength is important for a material that is going to be stretched or under tension. In many brittle materials such as rock, concrete, cast iron, tensile strength is almost negligible.

Tensile Modulus (GPa)

Tensile Modulus, also known as Young's modulus, is defined as the ratio of stress to strain. Rigid materials, such as metals, have a high Young's modulus. In general, fibers have high Young's modulus values, elastomers have low values, and plastics lie somewhere in-between.

Elongation at break (%)

The elongation at break is the strain on a sample when it breaks. This is usually expressed as a percent. The elongation at break is sometimes called the ultimate elongation. Fibers have a low elongation-to-break and elastomers have a high elongation-to-break

Izod impact Strength Notched (J/m)

Notched Izod Impact is a test of how impact resistant a polymer will be. This is useful information when the application is for high impact performance. The Izod Impact test is a measurement from energy used to break a notch in the specimens.

Flexural Strength (MPa)

The flexural strength of a material is its ability to resist deformation under load, or how much you can bend the material before it starts to break. Skis, fishing rods, pole vault poles and diving boards are examples of parts needing high flexural strength.

Vicat Softening Temp (℃)

The temperature at which a thermoplastic material reaches a specific level of softness. It is taken as the temperature at which the specimen is penetrated to a depth of 1 mm by a flat-ended needle with a 1 square mm circular or square cross-section.

Coefficient of Friction

The coefficient of friction, or COF, is described as the ratio of the force of friction between two bodies and the force pressing them together. A lower friction coefficient indicates that the surfaces are slicker - there is less resistance to the sliding motion.

Heat Deflection Temp - 1.8MPa (℃)

The Heat deflection temperature (HDT) is the temperature at which a polymer or plastic sample deforms under a specified load. A constant load is applied in the center of the specimen and the bath temperature is raised at a constant rate. The temperature of the bath at which the flexural deflection of the loading point has reached a predefined level is the heat deflection temperature of the material.
