Technical Information

Rubber Extrusion and Rubber Seals

Rubber extrusions are parts that are run through an extruder or extrusion machine and forced through a die to manufacture the necessary cross section (or extruded rubber shape), such as squares, cord shapes, and hollow sections. Cross and hollow sections add compression for sealing. Trim-Lok’s extruded rubber profiles are used for many functions, including:

  • • Window panes
  • • Garage doors
  • • Vehicle sunroofs
  • • Windshields
  • • Tonneau covers
  • • Boat hatches
  • • Other home and vehicle applications

At Trim-Lok, many of our sealing rubber parts are made from a custom- formulated EPDM sponge rubber that protects against extreme weather, drowns out noise, and eliminates vibration. Our rubber shapes are an ideal solution for your rubber extrusion and sealing needs.
