Silicone foam profiles are lightweight, heat-insulating, and offer excellent sealing performance. Used in automotive, construction, and electronics for sealing and cushioning, foaming requires extremely precise temperature and pressure control. PIPPL special foaming conical twin screws with optimized temperature-control structures and dual-alloy barrels deliver uniform cell structure and stable density for continuous silicone foam profile production.
Key Features
• Special foaming conical twin screw with precise temperature-control structure for controlled expansion.
• Low-shear design prevents premature foaming or cell collapse.
• Dual-alloy barrel withstands high-temperature silicone processing and curing conditions.
• Uniform cell structure and stable density across continuous production runs.
• Reliable long-term performance under demanding silicone foam process conditions.
Product Types
Closed-cell and open-cell silicone foam profiles for sealing, insulation, and cushioning applications.
