Reliable gap sealing directly affects equipment stability and service life. Foamed silicone seal strip is a widely‑used elastic sealing component built for general‑to‑heavy‑duty industrial environments. Produced by Tengye, this foamed silicone profile balances soft compressibility, stable rebound performance and long‑term aging resistance. It is extensively deployed across new‑energy, electronics, electrical enclosures and household appliance manufacturing.
Our foamed silicone seal strip is manufactured from high‑quality silicone raw compounds. Controlled closed‑cell extrusion foaming forms uniform inner pore structure. The finished strip features compact surface without powder shedding, cracking or delamination under repeated compression. Every batch follows complete in‑house quality control, covering raw material incoming check through to finished‑goods inspection. We support drawing‑based development and sample replication to achieve bespoke cross‑section, density and hardness for your project.
Broad temperature adaptability: Maintains stable elasticity within ‑60℃ to 230℃. Preserves reliable sealing performance under frequent cold‑hot alternation, avoiding hardening or permanent deformation after long‑time operation.
Excellent sealing & cushioning: High compressibility adapts to uneven assembly gaps, providing dust‑proof, waterproof, shock‑absorbing and noise‑reduction functions. Great ozone and UV resistance fits both indoor and outdoor working scenarios.
Stable compression resilience: Fine closed‑cell structure minimizes compression set. The seal strip can rebound well after millions of compression cycles for prolonged service life.
Optional self‑adhesive lamination: Acrylic adhesive layer can be applied on one side for fast installation onto metal, plastic and coated surfaces.
This foamed silicone seal strip fits a broad range of industrial sealing requirements:
New‑energy industry: Gap sealing for energy‑storage cabinets and auxiliary buffer gaskets for battery‑related equipment.
Electronic & electrical equipment: Dust‑proof and moisture‑proof sealing for control boxes, inverter housings and communication cabinets.
Household appliances: Cushion‑sealing for high‑temperature appliance shells, reducing operating noise and blocking dust intrusion.
Outdoor industrial devices: Weather‑resistant sealing for charging‑pile housings, lighting enclosures and general‑purpose industrial cabinets.
As a 15‑year silicone rubber source factory with in‑house tooling workshop, Tengye accepts both small trial orders and mass‑volume production. Custom development is supported based on customer drawings or physical samples. Adjustable parameters include cross‑section profile, thickness, density, color and adhesive treatment. Special‑formula options such as halogen‑free or flame‑retardant grades are available upon request. All finished products undergo full‑range inspection before shipment.
