Sulfur free silicone gel, with the core breakthrough point of "no need for secondary vulcanization", has demonstrated unique value in sensitive field applications. The curing process achieves rapid cross-linking of molecular chains through a precisely proportioned platinum catalytic system, and preliminary curing can be completed in 30 seconds at 120 ℃. The 2mm thick product reaches its final physical properties at 115 ℃ for 5 minutes, completely avoiding the energy consumption and time cost of traditional silicone rubber that requires several hours of high-temperature secondary vulcanization. This material is particularly prominent in infant care products, such as pacifiers and pacifiers that come into direct contact with infants' mouths. With a volatile organic compound content as low as 0.3%, it has passed the EN 14350-2 infant product safety standard and meets the strict requirements of BfR for food contact materials. Its surface is free of frost and precipitation, ensuring long-term safety.

In the medical field, the biocompatibility advantage of sulfur free silicone gel has been deeply explored. Surgical instrument sealing rings, respiratory mask gaskets, and other products that require strict sterilization have passed ISO 10993 and USP Class VI certification, and can maintain elastic stability during high-pressure steam sterilization at 121 ℃, avoiding performance degradation caused by secondary vulcanization of traditional materials. Its high and low temperature resistance (-55 ℃ to 230 ℃) is more suitable for the extreme environmental requirements of implantable medical components, such as the insulation layer of pacemaker leads and the coating material of nerve stimulation electrodes, maintaining stable electrical insulation performance and mechanical strength during long-term implantation.

The transparency and low migration properties of sulfur free silica gel are key advantages in food contact and industrial applications. Products such as baking mold liners and food sealing rings have no harmful substance precipitation under high temperature baking at 200 ℃, and have been certified by FDA 21 CFR 177.2600; The heat dissipation gasket of 5G communication equipment utilizes its high elasticity and thermal stability to maintain efficient thermal conductivity in a wide temperature range of -40 ℃ to 150 ℃, avoiding the problem of increased thermal resistance caused by secondary vulcanization of traditional thermal conductive silicone.
