UL94-V0 is the highest rating for the vertical flammability test of plastic and rubber materials, and a core entry requirement for rubber components used in electronic sealing and EV three-electric systems to enter European and American markets. Compliant products must satisfy two prerequisites simultaneously: halogen-free formulation and a full REACH substance test report, neither of which can be omitted. Standardized testing in accredited laboratories follows stringent procedures that require specialized combustion test chambers, Bunsen burners, and constant temperature & humidity preconditioning equipment. Such lab testing involves long lead times and relatively high costs, making it inefficient for workshops to rapidly screen modified rubber formulations.

To further enrich our sealing product lineup and meet the diversified high-standard sealing demands of global customers across multiple industries, our company has recently completed the mass production of the newly upgraded multi-purpose hose coupler gasket. Engineered for professional pipeline and hose connection sealing, this new gasket product features excellent environmental adaptability, stable sealing performance and wide application coverage, delivering reliable and cost-effective customized sealing solutions for automotive, industrial machinery, construction and HVAC fields.

Large industrial seals are prone to deformation in daily handling and testing, leading to inaccurate inner and outer diameter measurement results with traditional caliper tools. To solve this common industry pain point, we have launched a professional accurate measurement solution for large industrial seals. Eliminating manual reshaping operations, the system effectively reduces human and tool errors, realizes repeatable and consistent diameter data, greatly improves inspection accuracy and efficiency, and standardizes batch quality control. We continue to upgrade production and testing processes to deliver high-reliability sealing products for global industrial manufacturers.
