Product Description Product DescriptionExplore the exquisite art of customization with Ningbo Zhongmu Rubber Products Co., Ltd, where precision harmonizes with adaptability. Our holistic process ensures that each rubber product is masterfully crafted to fit your unique specifications. This remarkable journey involves selecting premium materials, optimizing performance, and refining process parameters, all while adhering to the pinnacle of industry standards:1. Raw Material Preparation and Pretreatment1. Main Material SelectionSelect the perfect type of raw rubber tailored to your product's specific needs. From the outstanding elasticity of natural rubber, the oil resistance of nitrile rubber, to the exceptional high-temperature resilience of silicone rubber, we provide an unparalleled selection that meets your exact requirements.2. Compound Agent DispensingElevate the rubber's performance by meticulously adding vulcanizers like sulfur or peroxide, along with promoters, anti-aging agents, and fillers such as carbon black or white carbon black. Attain unmatched precision with a minimal error margin of just 0.1%.3. Treatment of Reinforcement MaterialsTo ensure optimal binding strength, the skeletal material, be it steel wire or fiber, undergoes meticulous pretreatment. This involves soaking in rubber followed by precise drying at 60-70°C, ensuring superior integration with the rubber.2. Plastic Refining ProcessEnhance plasticity through cutting-edge mechanical extrusion or thermal oxidative degradation techniques to reduce molecular weight. Our state-of-the-art equipment, including opening and compacting machines, ensures a flawless execution of this process.1. Mechanical Plastic Smelting: Maintain a precise temperature of 60°C to effectively lower viscosity to under 60, guaranteeing smooth processing.2. Thermoplastic Refining: Ideal for natural rubber pretreatment, this method incorporates compressed air to achieve superior results.3. Mixed Refining ProcessAchieve impeccably consistent properties by uniformly dispersing the mixture using a high-performance rubber refining machine, resulting in a mixed rubber of unparalleled quality.Key control points: Maintain a temperature of ≤120°C, with a timeframe of 5-15 minutes, and a roll distance meticulously set at 1-3mm.Customized Adjustments:1. For products demanding exceptional wear resistance, increase carbon black content to 40-50 parts by weight to enhance durability.2. For products that must endure high temperatures, incorporate zinc oxide (5-8 parts by weight) alongside 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
