Everything you need to know about our products and company
Silicone potting compounds offer multiple functions in the electronics sector, including moisture-proofing, dust-proofing, corrosion resistance and shock resistance. These properties not only improve the performance of electronic products but also stabilize their technical parameters, making them widely favored by the electrical and electronics industry. Driven by higher power density and miniaturization of electronic devices, efficient thermal management has become critical. This fuels growing demand for silicone potting compounds with superior thermal conductivity and flame retardancy.
Silicone potting compounds are categorized into one-component and two-component grades. One-component products are popular for easy handling and no degassing requirement. Two-component systems, formed by mixing base polymer with catalyst or crosslinker, are widely used for insulating encapsulation and hermetic shock absorption. In terms of curing chemistry, condensation-cure and addition-cure systems are available. Addition-cure silicones are especially preferred because they produce no by products and enable fast curing.
In recent years, new nanocomposite silicones incorporating nano inorganic oxides deliver markedly improved heat resistance and UV stability. Their overall performance is further enhanced via sol gel condensation reactions and platinum catalyzed hydrosilylation.
For power applications, silicone potting compounds provide electrical insulation and corrosion resistance to secure long-term reliable operation of cable accessories. In automotive electronics, they safeguard stable operation of electronic systems with moisture resistance, corrosion protection and efficient heat dissipation.
The material’s resistance to water and lubricating oils guarantees reliable and durable operation of onboard equipment, suitable for both aqueous environments and lubricant exposure.
Looking ahead, developing silicone potting compounds with high transparency, radiation resistance and high thermal conductivity will be a key research focus. Further R&D into advanced nanocomposite silicones will continuously boost overall material performance to meet diversified application requirements.
