As the core catalytic system of silica gel (silicone material) addition reaction, platinum catalyst plays an irreplaceable role in hydrosilylation reaction, and is widely used in the production of addition silicone rubber, silicon gel, high thermal conductivity silicone material and medical grade silicone products. Its core function is to catalyze the addition reaction between silicon hydrogen bonds (Si-H) and vinylsiloxanes (Si Vi) to form a three-dimensional network structure, achieving cross-linking and curing of materials, thereby endowing organic silicon products with excellent properties such as high strength, high elasticity, and high temperature resistance.

The characteristics of platinum catalysts are reflected in multiple dimensions: high catalytic activity significantly reduces reaction activation energy and increases reaction rate. For example, in the hydrosilylation reaction, the sulfurization time can be shortened to less than 200 seconds; Its stability ensures stable performance in high temperature, high humidity, or complex chemical environments, avoiding decomposition or deactivation; Excellent anti toxicity can resist interference from impurities such as sulfur, phosphorus, and nitrogen, preventing catalyst poisoning; In addition, the amount of platinum is usually controlled within the range of 5-500 ppm, ensuring both catalytic efficiency and cost and environmental protection.

In the field of industrial applications, additive silicone rubber is widely used in mold manufacturing, electronic packaging (such as CPU heat dissipation silicone sheets), and medical equipment (such as medical silicone catheters) due to its advantages of no by-products, high transparency, and low volatility. In terms of high thermal conductivity materials, high thermal conductivity silicone grease and gel can improve the efficiency of electronic heat dissipation, thermal conductivity interface materials of lithium ion batteries maintain the uniformity of battery temperature, and high-temperature resistant, lightweight thermal conductivity materials play a key role in the thermal management system of aerospace engines.

In addition, platinum catalysts are also used to synthesize environmentally friendly flame retardants, improving the flame retardant performance of materials in the construction and transportation fields. The latest technological advancements include self-healing silicone gel (microencapsulated platinum catalyst, automatically triggering cross-linking reaction at cracks) and intelligent responsive materials (temperature sensitive platinum system, temperature triggered antibacterial factor release), further expanding their application boundaries.
