Engineered for the most demanding maritime environments, our sealing strips provide IP68-rated protection against seawater and extreme weather. Designed with a service life of 15+ years, these seals offer exceptional resistance to salt spray, UV radiation, and wind-wave impacts, ensuring long-term structural integrity for containers and vessels.
Temperature Range -50°C to 120°C
Salt Spray Resistance ≥1000 hours
Tensile Strength ≥10 MPa
Sealing Grade IP68
Complies with ISO 1436, GB/T 12754, and marine anti-corrosion standards.
Fully certified under the ISO 14001 Environmental Management System.
Verified for 1000h salt spray, seawater, and impact resistance.
Obtained specialized certifications for maritime and offshore applications.
With a fully vertically integrated production system, UPT achieves full-process control from polymer material formulation R&D to finished product certification and delivery.
Our company has successively obtained the three authoritative certifications of IATF 16949 Automotive Quality Management System, ISO 14001 Environmental Management System and ISO 9001 Quality Management System, fully meeting the stringent standards of various industries worldwide, especially those in the automotive sector.
During production of sealing strips, our QC engineers cut cross-sections for 10x magnified checks every 20 minutes. They accurately measure the rubber products’ dimensions, tolerances and geometric errors to ensure they match design drawings and meet customer assembly needs.
We also test the products’ physical and chemical properties per standards to guarantee complete vulcanization and stable performance. Friction and wear tests are carried out to check the abrasion resistance of rubber products and their coatings, while mechanical tests verify the material’s tensile and tear strength.

A: Yes. Through our Material Tuning process, we can adjust the EPDM or Nitrile formulation to withstand specific oils, acids, or industrial solvents. Simply provide your MSDS or environmental requirements.
A: We use high-precision molds and online laser measurement during the extrusion process. All profiles undergo Lab Validation to ensure they meet the ±[X]mm tolerance required by your CAD drawings.
A: Usually, mold development takes 7-12 days, and initial samples are provided within 3-5 days after tooling completion for your internal testing and fitment check.
A: Yes, our products meet IP67/IP68 sealing grades and comply with REACH/RoHS standards. We provide full test reports during the Lab Validation stage upon request.
A: We offer flexible Batch OEM Supply. While we have standard MOQs for mass production, we provide special support for specialized industrial projects with smaller volume requirements.
A: We use reinforced reels or custom-length flat packing with anti-static protection. Our Global Shipping protocol ensures that even the softest sponge profiles arrive without permanent compression set.
