Silicone Rubber Knowledge

硅胶模具验收不是确认样件能做出来，而是确认它能在稳定工艺下持续生产。尺寸、排气、脱模、毛边和维护便利性都应纳入 […]

Projects in the medical, food, and electronics assembly industries, among others, are setting increasingly specific requirements for the cleanliness of silicone components. Effective cleanliness control should address foreign matter, oil contamination, volatile residues, and packaging protection, while

Color is the most obvious quality indicator for silicone decorative parts. To achieve consistent color, it is not enough to rely solely on final inspection; instead, control must be exercised over the color masterbatch, the rubber compound, the vulcanization process, and the inspection lighting.

When silicone bellows are used for dust and water protection, guidance, and cushioning, the most critical factor is the stress distribution during dynamic stroke. This should be determined based on the installed length, compression ratio, extension, and connection end design.

Silicone overmolding provides a soft feel, a seal, and shock absorption all at once, but reliable adhesion cannot be achieved with a single adhesive alone. The substrate, surface condition, structural interlocks, and vulcanization conditions must

Conductive silicone rubber buttons use carbon particles or other conductive fillers to form contacts; they must provide a comfortable tactile feel while also ensuring low contact resistance and a long cycle life. During the design process, the mechanical structure and electrical

Silicone diaphragms are commonly used in valves, pump bodies, and pneumatic control systems. Their reliability depends on thickness uniformity, pressure differential, stroke, clamping structure, and the material’s long-term recovery performance. 1

Silicone tubing may appear to have a simple structure, but its actual performance is determined by a combination of dimensional stability, hardness, transparency, the medium it is exposed to, and the operating temperature. Clearly defining the boundary conditions at the start of a project can significantly

Liquid silicone rubber (LSR) and hot-cured silicone rubber (HCR) are not simply a matter of one being better than the other. When selecting a material for a project, factors such as structure, production volume, precision, appearance, and certification requirements should be considered to choose the most suitable option.

The key to selecting materials for oil- and chemical-resistant seals lies in the combination of “medium + temperature + time.” This article uses an engineering comparison to help quickly determine when to use F
