A plastic product manufacturer once suffered frequent shutdowns and repairs due to extruder overheating, resulting in delayed order deliveries, decreased customer satisfaction, and a shrinking market share. In just one year, the financial loss exceeded one million yuan. Such a shocking loss raises a critical question — why do extruders face high-temperature challenges?

Take a common plastic extruder for example. Raw materials enter the barrel through the hopper, where external heating devices quickly raise the temperature to 200°C–300°C to melt the material. The screw, driven by a motor, continuously rotates to push the molten material forward. Through compression and other forces, the material becomes fully plasticized into a uniform melt, which is then extruded through the die and cooled into products such as plastic pipes.

While high temperatures are necessary for plasticization, they also accelerate oxidation, deformation, and wear of key components like the screw and barrel. As a result, the lifespan of these parts may be reduced by more than 30%, compromising the precision and quality of the final products. So, what can be done?

Here's a secret — this thermal insulation coating can solve the high-temperature dilemma of extruders.

When applied to the extruder surface, it forms a dense insulation layer. Its internal structure, composed of hollow microspheres and nanofibers, effectively blocks heat conduction and reduces thermal convection and radiation. This significantly lowers the surface temperature of the equipment. Additionally, the coating has excellent anti-corrosion properties, slowing the aging of components and effectively extending the service life of the extruder.
