RTP 200 Series Compounds

This data provides comparative information on the shielding performance of standard RTP Company nylon 6/6 compounds using various combinations of additives and loading levels.

Instead of off-the-shelf solutions, RTP Company routinely develops specialty compounds with a precise combination of properties such as conductivity, flame retardance, structural reinforcement, color, and wear resistance to meet your exact application requirements.

RTP 200 Series
Nylon 6/6 Compounds

  • Strength
  • Stiffness
  • Heat resistance
  • Chemical resistance to hydrocarbons
  • Wear resistance and lubricity
  • Water absorption
  • Chemical resistance to strong acids and bases

Many types of nylon are commercially available. The most popular type is nylon 6/6, followed by nylon 6, then nylon 6/12, nylon 11 and nylon 12. Nylon 6/6 offers an excellent balance of properties and is the strongest of the nylons.

Nylons absorb more moisture than most other polymers. Moisture acts as a plasticizer, reducing tensile strength and stiffness. While absorbed moisture may reduce some properties, significant increases in elongation, impact strength, and energy absorbing characteristics are noted with increasing moisture content. Properly recognized and accounted for, the effect of moisture on the processing and properties of nylon need not be of great concern.

ASTM D4935: Standard Test Method for Measuring the Electromagnetic Shielding Effectiveness of Planar Materials

This test method provides a procedure for measuring the electromagnetic (EM) shielding effectiveness (SE) of a material due to a plane-wave, far-field EM wave. The test utilizes a coaxial transmission line to determine the shielding effectiveness of a given material. The test method is valid for a frequency range of 30 MHz to 1.5 GHz. Various thicknesses and types of materials can be tested to acquire a relative ranking of shielding effectiveness.
