How is the high temperature resistance effect of silicone plug?

According to the industry, different silicone plugs can be roughly divided into several kinds, and can also be limited to the temperature resistance conditions of silicone itself. For the through hole silicone plug, through hole silicone plug, countersunk screw thread type high temperature resistant rubber plug, the application fields of the three are different, so because of the different product material, thickness, temperature resistance effect is different, the selection of through hole type rubber plug is more standard. Good high temperature resistance. It is better to use gaseous silica gel to increase the density of the raw material. But the difference in the type of blind hole and thread is caused by the difference in shape and construction. High temperature contact makes the induction speed faster, making the high temperature effect of these two products relatively lower.

Through hole refers to the product is well connected, simple structure, wall thickness, there is nothing complicated in it, and the blind hole and threaded silicone plug product structure is not uniform and complex, so high temperature sensitivity can also improve the heat exchanger. But the principle is still in the range of high and low temperature resistance of silicone rubber products, the conventional test is about -40 to 230 degrees. However, with the structural characteristics of silicone rubber products manufacturers and the characteristics of raw materials, this limitation may be highlighted in order to achieve better temperature resistance. What is the temperature resistance effect of silicone plug, normal high temperature resistance or not?

Specifications selection of high temperature rubber plug and high temperature silicone plug for through hole: Generally speaking, high temperature rubber plug for through hole is the best choice, because the specifications of through hole are relatively standard holes (British or American system), and the specifications in the market are made in accordance with the British and American standards, so it is easy to purchase. It is only necessary to pay attention to whether the workpiece hole to be protected needs to be coated on one side or on the front. If it is a single coating, only need to select the size of the screw hole covered by the composite front coating can be. If it is double-sided paint, it is recommended to use suitable high-temperature rubber plug and high-temperature silicone plug for shielding protection on both sides.

The choice of blind hole with high temperature rubber plug and high temperature silicone plug: the choice of blind hole with high temperature rubber plug, only pay attention to the depth of the blind hole, the deeper the blind hole, the better the choice. The small head size of the high temperature silicone plug must be at least 1mm smaller than the diameter of the screw hole and other parts, and the big head size must be 1-2mm larger than the diameter of the parts to be protected. The required size varies depending on the depth of the threaded hole (the above data is for reference only).

Countersunk screw hole adopts high temperature rubber plug and high temperature silicone plug: it is difficult to choose shielding protection for countersunk screw hole in coating plating. The main reason is that the hole size, depth and taper of countersunk head screw are different, and general suppliers have no standard specifications to choose from. High temperature stickers are usually used to shield such workpieces. In addition, high temperature rubber plug and high temperature silicone plug are customized mold.
