Rock Wool Insulation for Hotend Heater Block

This rock wool insulation is designed to wrap the hotend heater block, reducing heat loss during printing. Its low thermal conductivity helps maintain a more stable temperature while improving heating efficiency.

Features

• Reduces heat loss from the heater block.
• Helps maintain a stable printing temperature.
• Low thermal conductivity.
• Lightweight, flexible and easy to fit around the hotend.

Material Properties

Thermal Performance

The rock wool structure traps dry, stable air, creating an effective barrier against heat transfer. Its thermal conductivity ranges from 0.031 to 0.050 W/m·K, providing excellent insulation against both high and low temperatures.

Fire Resistance

Rock wool is a non-combustible material classified as Euroclass A1. It retains its mechanical properties even when exposed to temperatures exceeding 1000 °C.

Applications

Ideal for insulating the heater block of FDM 3D printer hotends, helping to improve thermal stability and reduce heat loss during operation.
