Introduction
Standard sealing strips often fail to match unique equipment gaps, installation structures and special environmental requirements. OEM silicone sponge seal strip is a fully customizable elastic sealing part designed for personalized industrial sealing demands. As a professional silicone rubber manufacturer, Tengye provides one-stop OEM and ODM customization services, delivering tailor-made silicone sponge sealing solutions for new energy, electrical, household appliance and industrial equipment industries.
High-Purity Raw Material & Standard Sponge Foaming Process
Our OEM silicone sponge seal strip adopts high-purity industrial silicone raw materials with stable molecular performance, no harmful additives and no peculiar smell. Adopting precise closed-cell extrusion foaming technology, the product forms uniform and dense honeycomb pores inside the strip body. The surface is smooth and compact, with no powder falling, no cracking and no delamination after long-term repeated compression. All production procedures follow strict in-house QC standards, from raw material inspection to finished product testing. We fully support custom development according to customer drawings, 3D files or physical samples to meet personalized structural and performance requirements.
Key Performance Advantages
Wide temperature resistance: Maintains stable softness and sealing elasticity from -60℃ to 230℃. It adapts to long-term high-temperature baking and cold-hot alternating working environments without hardening, shrinkage or permanent deformation.
Excellent sealing & cushioning performance: Soft sponge structure fits irregular assembly gaps perfectly, realizing effective dust-proof, waterproof, moisture-proof and shock absorption effects. It greatly reduces equipment operation vibration and working noise.
Superior aging & weather resistance: Features outstanding UV resistance, ozone resistance and chemical corrosion resistance, suitable for long-term indoor and outdoor equipment operation, with stable performance and long service life.
Flexible functional customization: Optional halogen-free eco-friendly formula, flame-retardant grade and single-sided self-adhesive lamination to satisfy different industrial safety and installation standards.
Main Application Fields
