Auto weatherstrips (weatherstripping) are a crucial part of any vehicle which effectively seal the inside of the vehicle and prevent various outside elements like water, air, dust and noise from entering the vehicle cabin.

Now, the mostly used material for manufacturing weatherstrips is EPDM rubber which has superior resistance to outdoor weather, water, ozone, sunlight, etc. TPE/TPV and PVC are also used for some parts.

With state-of-the-art of manufacturing and testing equipment, Hebei Shida Seal Group has grown to be a leading supplier of automotive sealing systems and can design, develop and manufacture nearly all the body seals & weatherstrips that contribute to the performance and comfort in a car.

Material:

  • EPDM Sponge Rubber
  • EPDM Solid Rubber + EPDM Sponge Rubber

–Secondary Door Seal (Body Mounted) – Door Opening Trim Weatherstrip:

The rubber seal (trim seal) fits into vehicle body panel and plays a major role in isolating the vehicle cabin from outside water, air, dust and noise. The door seal also buffers impacts from the opening and closing of door and ensures easy closing and better sealing effect. It is often coated with colored EPDM rubber which has the same pattern with vehicle interior to provide elegant appearance.

Material:

  • EPDM Solid Rubber + EPDM Sponge Rubber + Metal Carrier
  • EPDM Solid + EPDM Sponge Rubber + Metal Carrier + Colored EPDM Coat

–Glass Run Channel (Door Glass Run):

Glass run channel is mounted to insides of the automotive door window frame and enable movable window glass to slide freely, and also stabilizes the glass during glass movement and door closing. The rubber channel is covered by flock or coated with abrasion resistance polyurethane(PU) coating to minimize friction during movement of the glass.

There are four types of glass run channel available at Hebei Shida Seal Group:

  • Flocked Glass Run Channel (EPDM Solid Rubber + Flock)
  • Coated Glass Run Channel (EPDM Solid Rubber + Polyurethane Coating)
  • Hybrid Glass Run Channel (EPDM Solid Rubber + TPE Slip-coating)
  • TPE-V (TPV) Extruded Glass Run Channel (TPV + Co-extruded on slip-coating)
