Product Description Product DescriptionEmbark on a seamless journey through the customization process of rubber products, meticulously designed to meet your precise requirements. From the careful selection of premier materials to the fine-tuning of performance through process parameter adjustments, each step is informed by cutting-edge industry practices:1. Raw Material Preparation and Pretreatment1. Main Material SelectionChoose the ideal raw rubber based on the product's specific application. Opt for natural rubber for unparalleled elasticity, nitrile rubber for exceptional oil resistance, or silicone rubber for superior high temperature resilience.2. Compound Agent DispensingEnhance your product's performance with precision by adding vulcanizers (sulfur or peroxide), promoters, anti-aging agents, and fillers (carbon black or white carbon black). Ensure accuracy with a weighing precision of 0.1%.3. Treatment of Reinforcement MaterialsTo boost binding strength with rubber, immerse the skeletal material (steel wire or fiber) in rubber and dry at a controlled 60-70°C.2. Plastic Refining ProcessEnhance plasticity by reducing raw glue's molecular weight through mechanical extrusion (via an opening machine) or thermal oxidative degradation (using a compactor).1. Mechanical Plastic Smelting: Carefully maintain a temperature of 60°C, reducing viscosity to lower than 60.2. Thermoplastic Refining: Ideal for the pretreatment of natural rubber, introduce compressed air to the process.3. Mixed Refining ProcessAchieve a consistent rubber blend by uniformly dispersing the mixture in the refining machine, ensuring homogeneous properties.Key control points: Regulate temperature (≤120°C), time (5-15 minutes), and roll distance (1-3mm) for optimal results.Customized adjustments:1. For high wear-resistant products: Amplify carbon black content to 40-50 parts by weight for enhanced durability.2. For high temperature resistant products: Incorporate zinc oxide (5-8 parts by weight) and a silane coupling agent for superior heat endurance.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 ParametersRubber materials and characteristicsnative rubber(NR)High elasticity (tensile strength 20-25MPa), wear resistance, tear resistance, but poor oil resistance and ozone resistancestyrene-butadiene rubber(SBR)Excellent wear resistance (low cost), but the elasticity, tear resistance is weaker than natural rubberbutadiene rubber(BR)Outstanding cold resistance (-70oC is still elastic), wear resistance, but low strength, poor tear resistanceDing eyes rubber(NBR)Excellent oil resistance (mineral oil, lubricating oil), low compression permanent deformation, but poor low temperature resistanceethylene-propylene rubber(EPDM)Optimal weather resistance, ozone resistance, high temperature resistance (150oC), good electrical insulation, but poor oil resistancechloroprene rubber(CR)Good aging resistance, ozone resistance and flame retardant, but poor low temperature performance (brittle below-30oC)silastic(VMQ)Temperature resistance range (-70~300oC), excellent biocompatibility, but low mechanical strengthfluorine(-containing)rubber(FKM)High temperature resistance (250oC), strong acid and alkali resistance, oil resistance, but poor air permeability, high processing difficultyhydrogenated butadiene-acrylonitrile rubber (HNBR) Oil resistance, high temperature resistance is better than ordinary NBR, wear resistance is strongchlorosulfonated polyethylene(CSM) Resistance to strong acid and strong alkali (such as concentrated sulfuric acid), ozone resistance, but poor oil resistanceurethane rubber(PU)Excellent wear resistance (high Shaw hardness), tear resistance, but poor oil resistance, weak weather resistanceacrylic rubber(ACM)High temperature resistance (200oC), oil resistance (such as ester lubricating oil), but poor cold resistancePackaging & ShippingInstallation InstructionsSuggestions 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)Company ProfileOur AdvantagesFAQ
