HNB devices operate at heating temperatures around 300\u00b0C. To prevent users from burns or scalding, an insulation layer is typically installed between the housing and heating chamber. This article outlines several heat insulation tube solutions for reference.<\/p>\n

1. LCP Insulation Sleeve
\nThe LCP (Liquid Crystal Polymer) insulation sleeve adopts a structure with inner and outer sleeves, with insulation cotton wrapped between them. The specially designed outer sleeve and LCP material's low thermal conductivity (lower than traditional PEEK resin) ensure effective heat insulation.<\/p>\n

- UL94 V-0 flame retardancy (highest fire safety rating for specialty plastics)
\n- Maximum heat deflection temperature: 340\u00b0C
\n- Excellent flowability for easy molding (minimum wall thickness: 0.2mm)<\/p>\n

The sleeve comprises inner and outer components, creating a cavity filled with insulation materials like cotton, aerogel, or foamed resin. Structural optimization of LCP reduces contact area with heating elements and thermal conduction, enhancing heat-blocking efficiency.<\/p>\n

2. PI Foam Insulation Tube
\nPolyimide (PI) foam, synthesized via supercritical processing into PI aerogel, retains PI's superior properties while significantly lowering thermal conductivity.<\/p>\n

- Operating temperature: -260\u00b0C to 300\u00b0C (short-term tolerance >350\u00b0C)
\n- Odorless at both ambient and high temperatures
\n- Modular, one-piece tube design for uniform insulation and consistent performance<\/p>\n

3. 3D-Printed Porous Ceramic Tube
\nThis 3D-printed ceramic tube employs an ordered gradient macropore structure combined with disordered micropores to create a high-porosity, low-thermal-conductivity composite.<\/p>\n

**Advantages**:
\n- 30% lower cost than conventional vacuum stainless steel tubes
\n- High-volume production capacity (2,000+ units\/hour)
\n- Enhanced insulation efficiency<\/p>\n
