Electrical Grade HTV Silicone Rubber YK-3160 for Composite Insulators
Product Summary
YK-3160 is a high-consistency silicone rubber (HTV/HCR) compound formulated specifically for molding housings and sheds of composite insulators. It delivers a balanced combination of electrical insulation, hydrophobicity, tracking and erosion resistance, mechanical strength, and outdoor weatherability. Suitable for injection or compression molding, it ensures stable processing and consistent part quality.
Key Selling Points
