Product Description Product DescriptionImmerse yourself in the sophisticated craftsmanship of our rubber products, where impeccable precision seamlessly fuses with versatile adaptability. Our all-encompassing approach ensures each rubber product is expertly customized to align with your exact requirements. This involves a meticulous selection of premium materials, strategic performance optimization, and careful fine-tuning of process parameters, all steered by the pinnacle of industry standards:1. Raw Material Preparation and Pretreatment1. Main Material SelectionSelect the perfect type of raw rubber that best suits your product's application. Whether you require the outstanding elasticity of natural rubber, the oil-resistant qualities of nitrile rubber, or the impressive high-temperature resilience of silicone rubber, we provide an unparalleled selection of top-tier options.2. Compound Agent DispensingElevate the rubber's capabilities by meticulously blending in vulcanizers such as sulfur or peroxide, alongside promoters, anti-aging agents, and fillers like carbon black or white carbon black. Attain extraordinary precision with an error margin that doesn't exceed a mere 0.1%.3. Treatment of Reinforcement MaterialsFor optimal adhesion and strength, the skeletal material-be it steel wire or fiber-is artfully pretreated. This involves an immersion in rubber followed by drying at an exact 60-70°C, ensuring a robust integration with the rubber.2. Plastic Refining ProcessBoost plasticity by diminishing molecular weight through advanced mechanical extrusion or thermal oxidative degradation techniques. Cutting-edge equipment like opening and compacting machines enhance this process.1. Mechanical Plastic Smelting: Maintain a precise temperature of 60°C to effectively lower viscosity below 60, ensuring seamless processing.2. Thermoplastic Refining: Ideally suited for the pretreatment of natural rubber, this technique introduces compressed air to achieve optimal refinement.3. Mixed Refining ProcessAchieve perfectly uniform properties by evenly dispersing the mixture within a high-performance rubber refining machine, producing a mixed rubber of exceptional quality.Key control points: Ensure a precise temperature maintenance of ≤120°C, within a 5-15 minute time frame, and a roll distance accurately set between 1-3mm.Customized adjustments:1. For products demanding extraordinary wear resistance, elevate carbon black content to 40-50 parts by weight to significantly enhance durability.2. For items that need to endure high temperatures, add zinc oxide (5-8 parts by weight) and a silane coupling agent for superior 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 key performance parametersindexNRNBRFKMSIREPDMTemperature resistance range-60~100oC-25~130oC-20~250oC-70~300oC-60~150oCoil resistivity insufficientexcellent(NBR40)extremely excellentinsufficientinsufficientozone resistanceinsufficientinsufficientexcellentexcellentexcellentabrasion performanceexcellentmiddlemiddleinsufficientexcellentElectric insulationexcellentinsufficientinsufficientexcellentexcellentSuggestions for type selectionOil 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 & Shipping Company Profile FAQ
