Thermoplastic vs. Rubber Comparison:

Thermoplastics Advantages:
  • Excellent choice for Static and Dynamic sealing requirements.
  • Good aesthetics for a Harmonized appearance. (COLOR, GLOSS, AND GRAINING)
  • Recycling potential.
  • Light weight w/o metal requirements- RIGID SUBSTRATES CAN BE DESIGNED TO SNAP FIT ONTO MATING PARTS BY DESIGN
  • Mechanical attachment robustness. MATERIALS ARE FORGIVING AND IMPROVE EASE OF ASSEMBLY while ONCE INSTALLED CAN BE DESIGNED FOR HIGH EXTRACTION FORCE
  • Thermoplastic Cross sectional tolerances can be held tighter than EPDM/NBR thermoset profiles while maintaining required Physical and Mechanical properties similar to those found in thermoset materials.
  • Target Applications: IP Seals, Pillar Seals, Rocker Seals, Spoiler Seals, WS and BW Glass Seals, Lower Dr. Guides
  • Ability to extruded low friction coatings to maximize anti itch/scratching properties to mating parts.
