Rubber Sealing strip

DescriptionAbout RNTICO Rubber Sealing StripRNTICO Extruded Rubber Sealing Strips are core sealing components designed to address critical challenges, including waterproofing, sound insulation, dustproofing, and shock absorption, safeguarding the stable performance and service life of your equipment.As a professional custom rubber sealing strip supplier, RNTICO produces a range of high-quality rubber materials, offering multiple color options and tailored solutions for various working environments.With a complete range of products, RNTICO covers all types of extruded rubber seal strips, including:solid rubber sealing stripsSponge rubber sealsDual durometer rubber seal extrusionsCo-extruded rubber profiles with metal carrier.Our Product Range of Extruded Rubber Seal StripsEPDM Rubber Seal Strip（Weather Resistant Series） Core Performance: – Excellent weather/UV/ozone/rain/snow resistance – Aging resistance & chemical stability – Temperature range: -40℃~130℃Applicable scenarios: Automotive/Construction doors/windows, ship hatches, industrial machinery shell sealingNitrile Rubber Strips（Oil-Resistant Series） Core Performance： – Excellent oil resistance (mineral oil, hydraulic oil, gasoline, diesel) – Good wear resistance – Temperature range: -40℃~120℃ Applicable scenarios: Engine compartment, hydraulic equipment, fuel tank surrounding, kitchen oil-contact scenariosSilicone Rubber Seal Strip（High-Temperature Resistant Series） Core Performance： – Extreme temperature resistance: -55℃~230℃ – Good electrical insulation performance Note: Poor tensile strength/wear resistance, non-oil-resistantApplicable scenarios: Oven/microwave door gaskets, automotive engine high-temperature components, aerospace instruments, medical equipmentNeoprene Sponge Rubber Seal Strips（Flame-Retardant Series）Core Performance： – Excellent flame retardancy & self-extinguishing properties – Weather resistance, wear resistance & moderate oil resistance – Temperature range: -40℃~100℃Applicable scenarios: Fire doors/windows, ship decks, electrical equipment shell sealingOther Available Rubber Materials for Sealing StripsIn addition to the above materials, we can also produce rubber sealing strips using various other materials, such as NR, FKM, PVC, TPE, TPV, etc., to fully meet the performance requirements of different products in diverse industries.Co-Extruded Rubber Seal StripsTo meet more complex working conditions, we adopt the co-extrusion process to integrally mold and bond two or more different materials into Co-Extrusion Sealing Strips, achieving the effect of “one sealing strip, multiple performances”.Dual Durometer foam and Solid Rubber ExtrusionsCo-extruded rubber sealing strips are normally made from EPDM solid and EPDM foam material. This composite design fully leverages the outstanding performance of EPDM in both solid and foam forms, delivering high-performance sealing solutions.Custom-engineered EPDM composite rubber sealing strips boast excellent compression set resistance, superior weather resistance, ozone resistance and UV resistance, along with high tensile strength, water resistance, and wide temperature resistance.Metal Insert Rubber Co-extruded ProfileOur Metal Insert Rubber Co-extruded Profiles are highly recognized in the market.The steel strip skeleton provides excellent rigidity, deformation resistance, structural grip, and easy installation; the rubber material offers elasticity, allowing it to closely fit the sealing surface, thus effectively resisting environmental stress, vibration, and wear for a long time.These Composite steel-reinforced rubber sealing strips combine the advantages of metal and rubber, ensuring superior sealing performance and service life.Co-extrusion rubber seal profiles are widely applied across multiple industries, including transportation, automotive (as auto rubber seal strips), industrial equipment, and construction doors & windows. RNTICO‘s Auto Rubber Seal Strip, as a key product in the automotive field, is specially designed to meet the strict sealing requirements of automotive doors, windows, engine compartments, and other parts, ensuring driving comfort and safety.Frequently Asked QuestionsWhat is the rubber sealing strip?Rubber sealing strips are elastic, strip-shaped sealing components made primarily of rubber through processes such as extrusion and compression molding. By utilizing their own elastic deformation to fill gaps, they achieve functions including waterproofing, dustproofing, sound insulation, shock absorption and sealing.What is the rubber sealing strip? – Read the full blog postWhat materials are RNTICO extruded rubber sealing strips made of?We offer EPDM, Nitrile, Silicone, Neoprene, NR, FKM, PVC, TPE, TPV etc., to meet different working conditions.Why are rubber sealing strips important?As a key sealing component, rubber sealing strips not only extend the service life of equipment and structures but also significantly improve product performance, safety, and user experience.Can RNTICO customize the Rubber Sealing strip?Yes, we support solid, foam, hollow, special-shaped cross-sections and tailor-made sizes based on your 2D/3D drawings.What's the production period of the customized rubber sealing strip in RNTICO?The production period of the rubber sealing strip depends on several factors. Such as the profile size of the rubber sealing strip, the complexity of the profile structure, the order quantity, etc. For more details, please feel free to contact us.How to select the right material for rubber sealing strips?The selection of rubber sealing strip materials should be based on the actual application scenario of the product (weather resistance/oil resistance/high and low temperature), combined with the material characteristics (EPDM weather resistance, NBR oil resistance, silicone high and low temperature resistance), and matched with the product’s technical requirements and cost budget. Our team can assist in selection.What is the difference between solid and foam rubber sealing strips?Solid sealing strips are high-density, wear-resistant, pressure-resistant, and tight sealing, making them suitable for high-pressure, wear-resistant, and leak-proof applications. Foamed sealing strips are soft, elastic, and possess excellent shock absorption and sound insulation properties; however, their pressure and wear resistance are slightly weaker, making them suitable for caulking, sound insulation, heat insulation, and low-pressure sealing applications.How to Maintain RNTICO Rubber Sealing Strips for longer life?Apply a rubber conditioner every 2–6 months based on the environment. Keep them away from sunlight, solvents, and sharp objects.How should I order the rubber sealing strip from RNTICO?Please inform us of your application requirements via [email protected] or WhatsApp 86-18149510829, and the engineer will assist you in selecting or designing the rubber sealing strip that best suit your needs.
