Silicone Rubber Knowledge

简要答案：硅胶表面低能，普通双面胶往往不能长期可靠粘接。背胶方案应同时匹配硅胶侧、被粘基材、使用温度和受力方式 […]

Short answer: Silicone has low surface energy, so direct bonding or printing often results in poor adhesion. Plasma treatment can activate the surface quickly, but the effect diminishes over time; therefore,

Short answer: In vacuum environments, it is important not only to address visible leaks but also to control outgassing from materials, permeation, cleanliness, and joint defects. Silicone is suitable for certain applications involving rough vacuum and higher temperature requirements.

Short answer: The key to low-temperature sealing is that the material remains flexible and resilient at the target temperature. Meeting hardness requirements at room temperature does not guarantee reliability at low temperatures; this must be evaluated in conjunction with the glass transition temperature.

Short Answer: Irregularly shaped silicone O-rings are suitable for irregular housings and continuous peripheral seals. Key design considerations include uniform cross-sectional compression, corner stress, positioning and anti-misalignment features, and mold parting lines, especially

Short answer: Foamed silicone strips have low compression force and are suitable for larger gaps and lightweight housings; solid silicone strips offer higher strength and wear resistance and are suitable for stable grooves and higher contact pressure. Choose

Short answer: Silicone cable protection sleeves are used to insulate against sharp edges on panels, limit cable bending, and improve the seal at the cable exit. When selecting a model, you should verify the hole size, panel thickness, cable diameter, tensile force, and

简要答案：硅胶防水塞要同时满足可装配、可维护和长期防水。关键在于孔径公差、密封筋过盈量、插入导向、拔出结构与材

Short answer: The holding force of a silicone suction cup is determined by its effective area, vacuum level, lip flexibility, and the contact surface. When selecting a model, do not rely solely on the diameter; you must also verify the surface roughness.

Short answer: Silicone umbrella valves achieve a one-way seal by having the umbrella surface contact the valve seat. A reliable design requires balancing the umbrella thickness, stem positioning, valve seat flatness, and assembly preload to avoid
