ASTM D471 Industry Standard for Rubber and Similar Materials
This standard is applicable to testing the performance changes of vulcanized rubber, rubber layers of coated fabrics, and finished rubber products (such as seals, hoses) in liquids. It is not applicable to porous rubber, sponge rubber, or compressed sheet fillers. Performance indicators and qualified thresholds: Weight change: Usually required to be ≤±5% (adjusted according to material type). Hardness change: Shore hardness change ≤±5 Shore A. Tensile strength retention rate: ≥70% (automotive grade requires ≥80%). 阅读详细内容…

Polysulfide Rubber Sealing Compound - SAE AMS3265F Industry Standard
Polysulfide rubber sealing compound, primarily used for sealing needs in fuel environments. The following are its core contents: Two-component room temperature curing polysulfide rubber sealing compound, containing non-chromate corrosion inhibitors, suitable for scenarios requiring contact with fuel, lubricating oil, or hydraulic oil—such as sealing of aircraft structural joints, wet installation of fasteners, joint sealing, and cabin pressure sealing. Its design goal is to maintain sealing performance during long-term contact with petroleum-based liquids (e.g., aviation fuels JP-4, JP-5) and to verify oil resistance through rigorous liquid immersion tests. Temperature resistance range:Long-term... 阅读详细内容…
Nitrile Butadiene Rubber (NBR) Products - MIL-R-6855E Military Standard

European Standard for Rubber Products EN 681-1:2023
Scope of application: Vulcanized rubber gaskets for water supply and drainage pipe joints, classified into oil-resistant (Oil Resistance) and non-oil-resistant types. Technical features: Hardness range: 40-90 International Rubber Hardness Degree (IRHD); tensile strength: ≥9 MPa; compression set: ≤20% (70°C × 24 hours). Ozone resistance test (ISO 1431-1) requires no cracking; low-temperature compression set (-25°C × 72 hours): ≤70%. The classification system clearly distinguishes between oil-resistant scenarios (for oil-contaminated wastewater) and non-oil-resistant scenarios, consistent with the classification logic of MIL-PRF-6855. Mechanical properties: Typical tensile strength ≥1500 psi (approximately 10.34 MPa); hardness... 阅读详细内容…
International Standard for Rubber Products ISO 6134:2024
Scope of application: Oil-resistant rubber hoses, classified into oil-resistant (Type B) and non-oil-resistant (Type A), suitable for conveying saturated steam and hot water condensate. Technical features: The operating pressure ranges from 0.6 MPa (6 bar) to 1.8 MPa (18 bar), with a temperature range of -20°C to 210°C. Required to resist media such as fuel oil and hydraulic oil, and designed for scenarios involving contact with petroleum-based liquids like fuel, lubricating oil, and hydraulic oil. Examples include aerospace engine seals, fuel line connections, and industrial hydraulic system seals. Their oil... 阅读详细内容…
