Overview

PRT® (S-3250)
  • Never disconnect or pull through another wire or cable again
  • Excellent anti abrasive, environmental, chemical, and electrical properties with resistance to most oils and fluids, mild acids, and alkalis
  • The PRT® (S-3250) EMI shielding material offers better shielding effectiveness of 65 db from 10MHz to 10GHz

PRT® (S-3250) is a wrap-around, MIL-SPEC polyolefin heat shrink tubing paired with our Z-3250 shielding cloth. The heat shrink is flame retardant, abrasion resistant, chemical resistant and fluid resistant, including resistance to jet fuel and Skydrol. The polyolefin tubing is RoHS compliant and UL-rated for flammability, meeting UL224, VW-1.

The Z-3250 shielding cloth offers exceptional EMI shielding performance. The shielding fabric is made of a nickel over copper-plated polyester taffeta cloth. The Z-3250 is flexible, yet very strong and provides excellent corrosion and environmental degradation resistance. PRT® (S-3250) can also be equipped with a 15 AWG braided wire for grounded applications.

PRT® (S-3250) can be cut to any desired length for versatility in applications. PRT® (S-3250) also only requires a standard heat gun for installation. PRT® (S-3250) is perfect for any industry, including the automotive and aerospace industries due to the high temperature range, resistance to abrasion, chemicals and fluids, and exceptional EMI shielding performance.

PRT® (S-3250) is offered in size ranges for diameters from 0.09” to 1.87”, as well as custom diameters upon request. The operational temperature range is -67°F to 275°F (-55°C to 135°C).

ATTENUATION DATA WAS OBTAINED USING MIL-DTL-83528H (MODIFIED). TESTING WAS PERFORMED BY ACCREDITED, THIRD-PARTY EMI LABORATORIES.
