Product Description Product DescriptionEmbark on a journey of unparalleled customization with our premium rubber products, where meticulous precision seamlessly marries with adaptability. Our all-encompassing process is designed to ensure each rubber product is sculpted with exactitude to meet your every need. This involves the strategic selection of top-tier materials, the meticulous optimization of performance, and the flawless fine-tuning of process parameters, all steered by the pinnacle of industry standards:1. Raw Material Preparation and Pretreatment1. Main Material SelectionSelect the quintessential type of raw rubber tailored to your product's unique function. Whether you require the extraordinary elasticity of natural rubber, the superior oil resistance of nitrile rubber, or the outstanding high-temperature endurance of silicone rubber, our collection ensures you have the optimal choice.2. Compound Agent DispensingElevate your rubber’s performance by meticulously administering vulcanizers such as sulfur or peroxide, along with promoters, anti-aging agents, and fillers like carbon black or white carbon black. Attain precision with an impressive minimal error margin of just 0.1%.3. Treatment of Reinforcement MaterialsFor peak binding strength, the skeletal material, whether it's steel wire or fiber, undergoes meticulous pretreatment. This involves immersing in rubber and drying at a precise 60-70°C to ensure exceptional integration with the rubber.2. Plastic Refining ProcessAugment plasticity by expertly reducing molecular weight through cutting-edge mechanical extrusion or thermal oxidative degradation techniques. Leverage state-of-the-art equipment such as opening and compacting machines for this advanced procedure.1. Mechanical Plastic Smelting: Maintain a precise 60°C temperature to effectively lower viscosity below 60, ensuring seamless processing.2. Thermoplastic Refining: Ideally suited for natural rubber pretreatment, this method utilizes compressed air to achieve superior results.3. Mixed Refining ProcessAchieve impeccable consistency by uniformly dispersing the mixture in a high-performance rubber refining machine, crafting a mixed rubber of unmatched quality.Key control points: Ensure a precise temperature of ≤120°C, time range of 5-15 minutes, and a roll distance meticulously set at 1-3mm.Tailored Customizations:1. For products demanding exceptional wear resistance, increase the carbon black content to 40-50 parts by weight to significantly enhance durability.2. For products needing to endure high temperatures, integrate zinc oxide (5-8 parts by weight) along with a silane coupling agent for outstanding performance.3. For the Moulding Process:Placement formingSuitable for rubber plates and sealing strips, it is necessary to control the adhesive thickness tolerance within ± 0.1mm.Extrusion and shapingFor the hose and sealing ring, the design of the mouth die directly affects the accuracy of the section.Modular pressure moldingMetal-rubber composite molds should be used for complex structures.Injection moldingComplex structural parts are multi-material composite componentsDetailed PhotosProduct ParametersComparison of Essential Performance ParametersindexNRNBRFKMSIREPDMTemperature resistance range-60~100oC-25~130oC-20~250oC-70~300oC-60~150oCoil resistivity insufficientexcellent(NBR40)extremely excellentinsufficientinsufficientozone resistanceinsufficientinsufficientexcellentexcellentexcellentabrasion performanceexcellentmiddlemiddleinsufficientexcellentElectric insulationexcellentinsufficientinsufficientexcellentexcellentOptimal Type Selection SuggestionsOil resistance sceneNitrile rubber (NBR) or fluorine rubber (FKM) is preferredhot environment Silicone rubber (VMQ) or fluorine rubber (FKM)resistance to chemical attack Chlorosulfated polyethylene (CSM) or fluorine rubber (FKM)dynamic packingEthpropylene rubber (EPDM) or polyurethane rubber (PU)Packaging & ShippingCompany ProfileFAQ
