Silicone foam tubes are lightweight, thermally insulating, and flexible. They are used for insulation, sealing, and medical applications. Uniform cell structure and smooth inner surface are critical. PIPPL foaming-dedicated conical twin screws with precise pressure control and dual-alloy barrels ensure consistent foam quality and reliable continuous production of silicone foam tubing.
Key Features
• Foaming-dedicated conical twin screw with precise pressure control for uniform cell structure.
• Low-shear design maintains foam integrity throughout the extrusion process.
• Dual-alloy barrel suitable for high-temperature silicone curing processes.
• Stable continuous output with consistent density and wall quality.
• Smooth inner surface suitable for insulation and medical applications.
Product Types
Silicone foam insulation tubes, sealing hoses, and medical-grade foam tubing in various diameters and densities.
