Polyvinyl chloride (PVC) heat tubes are widely used in various industries for their excellent heat resistance properties. These tubes are designed to withstand high temperatures without deforming or melting, making them ideal for applications where heat resistance is crucial. In order to ensure the proper performance of PVC heat tubes in different temperature conditions, they are classified into various heat resistance grades. These grades are determined based on the maximum temperature at which the tubes can operate without compromising their structural integrity. In this article, we will discuss the classification of heat resistance grades for PVC heat tubes and their applications in different industries.

PVC heat tubes are classified into different heat resistance grades based on their maximum operating temperature. The most common heat resistance grades for PVC heat tubes are as follows:

1. Low Heat Resistance Grade (up to 60°C): PVC heat tubes with low heat resistance grades are designed to withstand temperatures up to 60°C. These tubes are suitable for applications where low to moderate heat resistance is required, such as in household appliances, automotive components, and electrical wiring.

2. Medium Heat Resistance Grade (up to 80°C): PVC heat tubes with medium heat resistance grades can withstand temperatures up to 80°C. These tubes are commonly used in industrial applications where moderate heat resistance is needed, such as in chemical processing, food processing, and water treatment.

3. High Heat Resistance Grade (up to 100°C): PVC heat tubes with high heat resistance grades are capable of withstanding temperatures up to 100°C. These tubes are ideal for applications where high heat resistance is essential, such as in steam handling, hot water circulation, and HVAC systems.

4. Ultra-High Heat Resistance Grade (above 100°C): PVC heat tubes with ultra-high heat resistance grades can withstand temperatures above 100°C. These tubes are specifically designed for extreme heat resistance applications, such as in aerospace, automotive racing, and industrial manufacturing.
