Also known as acetal homopolymer and polyoxymethylene (POM), Delrin® acetal resin combines strength and wear resistance with good chemical resistance. It also absorbs less moisture than nylon. Delrin® acetal resin is NSF, FDA, and USDA compliant, All meet ASTM D6100.

Tensile Strength–

The maximum pulling force a material can withstand without breaking. It is usually measured in pounds per square inch (psi). A larger number indicates a stronger material.

Coefficient of Friction-

The ratio of the frictional force between two surfaces in contact, to the force with which the surfaces press against each other. A lower value indicates a material that moves more easily, or with less friction.

Impact Strength-

The ability of a material to withstand shock loading. Determined by the notched Izod test, which measures the effect on a material when it is suddenly impacted by a swinging pendulum. A larger number signifies greater impact resistance.

Flexural Modulus of Elasticity-

The stiffness of a material. The higher the number, the stiffer the material; the lower the number, the more flexible it is.

Short- Term Dielectric Strength –

The maximum voltage a material can withstand without rupture, measured as volts per millimeter of thickness. This is an indication of how effective the material is as an electrical insulator. A higher value signifies a better insulator.
 

Coefficient of Thermal Expansion-

The amount a material increases in volume as the temperature rises. A smaller coefficient is an indicator of less thermal expansion.

Thermal Conductivlty-

The ability of heat to travel through a material. A lower value is an indicator of a better insulator.
