In new energy systems, industrial equipment and automotive thermal management, pipelines and harnesses face dual challenges of high-temperature heat loss and external heat invasion. Composite foam insulation silicone tube is a high-performance multi-layer structural thermal insulation material, designed with composite laminated technology integrating dense foam core and reinforced outer layer. It breaks through the performance limitations of single-layer foam tubes, providing ultra-efficient thermal insulation, enhanced compression resistance and longer service life. Our products adopt high-purity silicone raw materials and precision co-extrusion composite process, delivering stable thermal insulation, heat preservation, flame retardant and anti-aging protection for complex working conditions.
Premium Composite Material & Laminated Foam Process
Our composite foam insulation silicone tube uses
inner foam layer + outer dense silicone layer composite structure, with imported high-purity silicone and halogen-free flame-retardant formula, environmentally friendly and non-toxic. The inner layer adopts high-density closed-cell foaming technology, with uniform and fine pore structure (density 0.2–0.6g/cm³), maximizing thermal insulation efficiency; the outer layer is made of reinforced dense silicone, enhancing wear resistance, compression resistance and structural stability.
Integrated co-extrusion and high-temperature vulcanization process ensures strong bonding between layers, no delamination or peeling after long-term use. The product features ultra-wide temperature resistance of
-60℃ to 280℃, maintaining soft toughness and physical stability under extreme temperature cycles, no hardening, cracking or deformation. All products comply with RoHS 2.0, REACH, UL 94 V-0 and FDA standards, with SGS and Intertek test reports available.
Core Performance Advantages (Composite Structure Upgrade)
Compared with single-layer foam tubes, our composite foam insulation silicone tube has comprehensive performance upgrades, focusing on high-efficiency insulation and structural durability:
- Dual-Layer High-Efficiency Insulation: Inner closed-cell foam layer forms air insulation barrier (thermal conductivity ≤0.1W/m·k), reducing heat transfer by 30%+ vs single-layer tubes; outer dense layer isolates external heat, achieving dual effects of heat preservation in winter and insulation in summer.
- Enhanced High & Low Temperature Resistance: Stably resistant to 280℃ high temperature and -60℃ low temperature, adapting to long-term thermal radiation and cold-hot alternating environments, no performance attenuation.
- UL 94 V-0 Top-Tier Flame Retardancy: Self-extinguishes quickly after leaving fire, no molten dripping or toxic smoke, effectively blocking flame spread and avoiding ignition risks.
- Reinforced Compression & Structural Stability: Outer dense silicone layer improves compression resistance (compression set ≤12%), no permanent deformation after long-term extrusion, maintaining stable wrapping effect.
- Wear-Resistant & Anti-Aging: Outer layer resists friction, vibration and chemical corrosion; inner foam layer is anti-aging and weather-resistant, extending service life by 50%+ vs single-layer tubes.
- Safe & Environmentally Friendly: Non-toxic, odorless, chemically inert, no corrosion to metals and plastics; excellent electrical insulation prevents short circuit and leakage.
Main Application Scenarios
Widely used in high-standard thermal insulation and protection scenarios in new energy, automotive, industrial and electronic fields:
- New Energy Industry: Thermal insulation for battery high-voltage harnesses, energy storage pipelines and thermal management lines, reducing heat accumulation and improving safety.
- New Energy Vehicle Industry: Engine compartment pipelines, high-voltage lines and motor cooling pipe insulation, adapting to high temperature and vibration.
