Key Details Regarding Thickness and Tolerance Thickness  -is a core consideration when selecting 3240 epoxy board. The product's standard thickness ranges from 0.1mm to 20mm, with a complete range of specifications to meet the insulation, support, and partitioning needs of different scenarios.

Heat insulation panels are industrial-grade panels used to block heat transfer. They are made from a high-density, high-temperature resistant, inorganic composite flame-retardant substrate, pressed under high pressure. The core essence of heat insulation is reducing the overall thermal conductivity of the material. The panel is filled with numerous sealed micropores. When heat passes through the panel, it is transferred simultaneously through the solid substrate and the air within the pores: the solid substrate transfers heat via conduction, while the heat exchange process within the pores is more complex.   The product simultaneously inhibits three heat transfer pathways: conduction, convection, and radiation. Combined with the principle of heat shield reflection insulation, it comprehensively blocks the outward diffusion of high temperatures.   Blocking Heat Conduction: When metal molds are directly bonded to equipment mounting plates, heat conduction is rapid, and heat is easily lost. The heat insulation panel, sandwiched between the two, uses the low thermal conductivity composite substrate to cut off the solid heat conduction channels, firmly locking in the temperature of the mold cavity.   Reducing Heat Radiation: Special fire-resistant reflective filler is added inside the panel to reflect and absorb infrared radiation heat released from the mold, reducing heat radiation and preventing continuous overheating and damage to the machine tool frame.   **Insulation of Thermal Convection:** The dense, seamless sheet material prevents hot air from penetrating and facilitating thermal convection, reducing temperature loss at its source.   **Layered Gradient Buffer Insulation Structure:** The sheet material is formed using a multi-layered, integrated hot-pressing composite process. The stacked layers of insulation create a gradient temperature difference: the side closest to the mold maintains a high temperature, while the heat transferred to the machine tool side is significantly reduced after passing through multiple buffer layers. The greater the sheet thickness, the longer the temperature buffer attenuation range, resulting in superior insulation and energy-saving performance.   **Dual Working Logic of the Mold:** The insulation plate is typically installed between the mold fixing plate and the injection/die-casting equipment template. The high temperature generated during mold operation is significantly reduced in heat transfer to the machine tool body after being buffered by the multiple layers of insulation. This prevents heat loss from the mold interior, ensuring consistent product quality during mass production. Furthermore, it prevents the machine tool from operating in a high-temperature environment for extended periods, effectively protecting hydraulic components, guide rails, and other metal parts, delaying equipment aging, and reducing the continuous operation time of heating coils, thus lowering the overall energy consumption of the production line.

The temperature resistance of teal fiberglass boards will gradually decline as service time increases. This is determined by the material properties and aging rules of the substrate. The specific change mechanisms and influencing factors are as follows:   Core Causes of Aging   The substrate of teal fiberglass boards is a composite material of epoxy resin and glass fiber. As a polymer, epoxy resin undergoes thermal-oxidative aging under the long-term continuous effect of environmental factors such as temperature, humidity and oxygen:   High-temperature environments will accelerate the breakage of epoxy resin molecular chains and reduce the bonding strength between the resin and glass fibers; In humid environments, moisture will penetrate into the interior of the board, damage the interface bonding between fibers and resin, and further accelerate the aging process.   This aging process is irreversible and will eventually lead to a gradual reduction in the maximum temperature resistance of the board.

  The continuous safe operating temperature ranges from 80–100℃. Within this range, the sheet maintains long-term structural stability without deformation, softening, or releasing harmful substances. It is suitable for food processing scenarios such as hot water cleaning and short-term steam sterilization.   The instantaneous high temperature resistance can reach 120℃ (for a duration not exceeding 30 minutes). Exceeding this temperature will cause softening and deformation. Prolonged exposure to environments above 100℃ will accelerate sheet aging, reduce toughness and shorten service life.   Note: Do not directly contact open flames or high-temperature heat sources, otherwise melting and combustion may occur.     Regular food-grade PP sheets retain good toughness and impact resistance in environments above -20℃ without brittle cracking. They are applicable to low-temperature scenarios including fresh food cold chain warehousing and refrigeration equipment accessories.   When the temperature drops below -20℃, the sheet’s toughness gradually decreases, impact resistance weakens, and it is prone to cracking upon external impact. Some modified food-grade PP sheets (e.g., those added with cold-resistant additives) can withstand temperatures as low as -40℃. For specific parameters, please refer to the product test report.

Celuka board and PVC foam board are actually the same material. Celuka board, whose full name is PVC foam board, is a lightweight sheet produced by using polyvinyl chloride (PVC) resin as the primary raw material, adding additives such as foaming agents and stabilizers, and adopting extrusion or molding processes. It has a closed-cell foam structure inside, with a smooth surface and high hardness.

  CNC Cutting CNC cutting machines or laser cutting equipment are adopted to precisely cut sheets according to customer-provided drawings, which can produce square, round or simple special-shaped parts of different dimensions. Featuring high precision and burr-free edges, this process is suitable for batch cutting of thin to medium-thick sheets, and is commonly used in manufacturing basic components such as sealing gaskets and insulation partitions. CNC Engraving & Milling CNC engraving and milling machines are used for precision machining of sheets, capable of milling complex grooves, holes, threads and irregular contours. During processing, cutting speed and feed rate must be strictly controlled, and special tools should be used to avoid local edge melting or deformation caused by PTFE’s poor thermal conductivity. This process is ideal for manufacturing precision mechanical parts and equipment liners. Grinding & Polishing For products requiring high surface finish, precision grinding and polishing equipment is applied to treat the sheet surface. Surface roughness is reduced through progressive grinding, which improves flatness and wear resistance. This process is widely used in scenarios with stringent requirements for friction coefficient and sealing performance, such as seals and sliding guide rails. Hot Press Forming For special-shaped parts that need bending or shaping, the hot press forming process is adopted: PTFE sheets are heated to a specific temperature, then pressed with molds and cooled for shaping, which can produce special structures like arcs and bent parts. This process maintains the original properties of the material and prevents cracking caused by cold bending, making it suitable for manufacturing pipe liners and equipment protective covers. Drilling & Tapping Specialized drilling equipment and taps are used to process through holes, blind holes and threaded holes of various specifications on sheets. Attention should be paid to chip removal during processing to prevent chips from adhering to tools and affecting precision. This process is often used for PTFE sheet components that require assembly and fixation.
