High Temperature Curing Conductive Rubber
Overview
High Temperature Curing Conductive Rubber is an advanced composite material that combines elastomeric properties with electrical conductivity. It is engineered to withstand elevated temperatures while maintaining consistent electrical performance. This material typically consists of a silicone or fluorosilicone rubber matrix filled with conductive particles such as silver, nickel, or carbon. The high temperature curing process ensures stable performance in demanding applications where conventional conductive rubbers would degrade.
Physical and Chemical Properties
The material exhibits excellent thermal stability, typically maintaining its properties between -50°C to +200°C. Its electrical resistivity can range from 0.01 to 10 ohm-cm depending on formulation. Chemically, it demonstrates good resistance to oils, fuels, and many solvents. The rubber matrix provides flexibility and vibration damping characteristics, while the conductive fillers create continuous pathways for electrical current flow. Surface resistivity is typically uniform across the material.
Main Applications
Primary applications include EMI shielding gaskets in aerospace and defense electronics, where it prevents interference in sensitive equipment. Automotive uses include fuel system sensors and engine compartment electronics. The material is also employed in industrial settings for static control in cleanrooms and as flexible heating elements. Medical applications include conductive components for imaging equipment that require repeated sterilization cycles.
Safety and Storage
While generally safe, some formulations may contain nickel or other metal particles that could cause allergic reactions. Proper ventilation is recommended when machining or cutting the material. Storage should be in original packaging at room temperature with less than 70% humidity. Shelf life is typically 12-18 months when stored properly. Avoid contact with strong acids or oxidizing agents which could degrade the material.
B2B Procurement Guide
When sourcing High Temperature Curing Conductive Rubber, clearly specify your required volume resistance (ohms per square), operating temperature range, and environmental exposure requirements. For custom shapes, provide detailed drawings including tolerance requirements. Lead times for custom formulations can be 4-8 weeks. Consider requesting material certification and test reports for critical applications. Bulk purchases (100kg+) typically qualify for 10-20% discounts.
