Silicone products believe that many people already know that it is an environmentally friendly, non-toxic, healthy and safe material, but what are the factors that affect the production process.
1. Viscosity: explanation of scientific and technological terms: the volume characteristics of liquid, pseudo-liquid or pseudo-solid substances to resist flow, that is, when flowing under the action of external force, the internal friction or internal resistance between molecules is presented, usually the viscosity and hardness are proportional.
2. Hardness: The ability of materials to partially resist hard objects pressed into their surfaces is called hardness. Silicone rubber and silicone products have a Shore hardness range of 10 to 80, which gives designers sufficient freedom to choose the required hardness to best realize specific functions. Mixing polymer substrates, fillers and additives in different proportions can achieve various intermediate hardness values. Similarly, the time and temperature of heat curing can also change the hardness without destroying other physical characteristics.
Silicone Products Factory 3. Tensile strength: Tensile strength refers to the force required on each range unit to cause a sample of rubber material to tear.
Conductive silicone rubber is based on silicone rubber, adding conductive filler, crosslinking agent and other blending and vulcanization, commonly used rubber for methyl vinyl silicone rubber, commonly used conductive fillers are acetylene carbon black, carbon fiber, superconducting carbon black, graphite, copper powder, silver powder, aluminum powder and zinc powder.
Compared with general conductive rubber, conductive silicone rubber has the advantages of small volume resistivity, low hardness, high and low temperature resistance (-70 to 200 ℃), aging resistance, and good processing and manufacturing process performance. It is especially suitable for manufacturing conductive rubber products with good performance, complex shape and small structure. It has the characteristics of high and low temperature resistance, aging resistance, and easy molding processing of common silicone rubber, and has good conductive stability and thermal stability.
Because conductive silicone rubber has the advantages of small size, stable and reliable contact, good shockproof performance, and convenient replacement, it is used for the connection between printed circuits, radio integrated circuits, displays, etc., which can save a lot of welding labor and simplify assembly. Reduce the volume, reduce the cost, and improve the reliability.
