German Brandenburger KV3 insulation board in the mold industry

Brandenburger KV3 is a high-tech insulation material based on glass fiber reinforced thermosetting composite materials, and its formula and process endow it with comprehensive insulation properties.

Temperature resistance: It can withstand temperatures up to 250 ° C in the long term and up to 280 ° C in the short term. This feature enables it to adapt to the thermal working conditions of most mold processing.

Thermal conductivity: The thermal conductivity is 0.25-0.3 W/mK ⟮ 1 ⟯⟮ 6 ⟯⟮ 8 ⟯. Low thermal conductivity ensures that heat is effectively concentrated in the mold cavity, reducing heat loss.

Thermal stability: The linear expansion coefficient is as low as 11 × 10 ⁻⁶⟮ 6 ⟯⟮ 7 ⟯, with excellent dimensional stability under temperature changes, avoiding dimensional deviations caused by thermal expansion and contraction.

Features:

Compressive strength: The compressive strength at room temperature can reach up to 650-700 N/mm ², and even at a high temperature of 200 ° C, it still maintains a compressive strength of 450-500 N/mm ².

Bending strength: reaching 600 N/mm ² ⟮ 6 ⟯ 7 ⟯, ensuring that it is not easily deformed or broken under load conditions.

Dimensional stability: The extremely low setting performance ensures dimensional stability under stress and strain conditions, which is crucial for high-precision mold applications.

KV3 insulation board has various applications in the mold industry:

Heating press: used as insulation material for pistons and frames, or for heating pressure plates in molds and tools

Injection mold: Especially in high-temperature plastic (such as engineering plastics) injection molding, reducing heat loss and improving efficiency

Die casting mold: As a thermal insulation layer between the mold and the machine template, it protects the die casting machine template from high temperature effects

Rubber vulcanization mold: Provides uniform temperature distribution to ensure consistency in the vulcanization process.

Key selection points

The following factors should be considered when selecting a suitable KV3 insulation board:

Temperature requirement: Evaluate the working temperature of the mold to ensure long-term temperature resistance within 250 ° C of KV3

Pressure conditions: Calculate the required compressive strength based on the mold locking force, and KV3's 700 N/mm ² compressive strength can meet most mold requirements

Size specification: KV3 insulation board can be produced in different sizes according to customer requirements, and precise measurement of installation space is required
