Endless sealing systems
The extruded strand becomes a closed ring or frame – joined low-seam and robust by film splice vulcanization.
Typical materials
- EPDM
- Silicone
- NBR
The product
Many seals are not installed by the metre but as closed rings or frames: in housings, control cabinets, containers, windows or tunnel segments. The joint is the critical point.
Typical products
- Sealing rings from profiles and cords
- Sealing frames for housings, cabinets and containers
- Frames for windows and doors
- Tunnel segment gaskets
What matters
- 01
Low-seam joint
The joint should be neither visible nor noticeable.
- 02
Strong
The joint must withstand the same forces as the profile.
- 03
Exact length
Accurately sized rings and frames for installation.
