在工业领域, silicone rubber sheets are a common material with a wide range of applications. The tolerance range of the thickness of silicone rubber sheets is one of the important factors affecting their usage effect and quality stability. Let’s take a closer look at the relevant knowledge about the tolerance range of the thickness of silicone rubber sheets.
Silicone rubber sheets are industrial rubber sheets made mainly from silicone. They come in various thickness specifications, such as 1mm, 2毫米, 3毫米, ETC. Silicone rubber sheets of different thicknesses are suitable for different application scenarios. 例如, in some scenarios that require greater cushioning or sealing, thicker silicone rubber sheets may be chosen; while in places with strict space requirements, thinner silicone rubber sheets are more appropriate.
When it comes to the tolerance range of the thickness of silicone rubber sheets, 一般来说, the thickness tolerance of ordinary precision silicone rubber sheets is usually around ±0.1mm.
This means that if a silicone rubber sheet is marked with a thickness of 2mm, its actual thickness may be within the range of 1.9mm to 2.1mm, which is considered normal. This tolerance range can meet the requirements of most conventional industrial applications. 例如, in scenarios where the dimensional accuracy requirements are not extremely high, such as sealing gaskets and general protective pads, a tolerance of ±0.1mm will not have a significant impact on the overall usage effect.

For some high-precision application scenarios, the thickness tolerance of 硅胶橡胶板 needs to be controlled within a stricter range.
例如, in scenarios involving the sealing of precision instruments or the keys of electronic devices, the tolerance range often needs to be within ±0.05mm. If the thickness tolerance of the keys on a silicone keyboard is too large, it may lead to inconsistent key feel, or even problems such as unresponsive or stuck keys; in some precise hydraulic or pneumatic systems, if the thickness of the silicone rubber sealing parts does not meet the high-precision tolerance requirements, it may not achieve a good sealing effect, thereby affecting the normal operation of the entire system.
To ensure that the thickness of silicone rubber sheets meets the corresponding tolerance range, strict control is needed in every step of the production process.
From the proportioning of raw materials to the control of the molding process, 每个步骤都是至关重要的. Every batch of produced silicone rubber sheets needs to undergo strict thickness measurement. Once products are found to exceed the tolerance range, they need to be reprocessed or replaced directly to ensure the stability of product quality.
In addition to thickness tolerance, silicone rubber sheets also have corresponding tolerance standards for other dimensions.
例如, the parallelism tolerance should not exceed 1% of the product length, and the perpendicularity tolerance should not exceed 1% of the product height, ETC. These tolerance standards work together to ensure that silicone rubber sheets can accurately perform their intended functions in practical applications.
