Rubber insulation cotton, as a widely used insulation material in construction, industry, and other fields, its temperature resistance performance is a key indicator for measuring usage scenarios. The temperature resistance range of rubber insulation cotton produced by different materials and processes varies significantly, and it needs to be selected reasonably according to specific needs.

The temperature resistance foundation of rubber insulation cotton

The temperature resistance range of ordinary rubber insulation cotton (such as EPDM rubber material) is usually between -50 ℃ and 120 ℃. Maintaining flexibility in low temperature environments and maintaining structural integrity under high temperature conditions, suitable for scenarios such as conventional building pipelines and air conditioning systems. This temperature range covers most civilian and light industrial application scenarios.

Breakthrough performance of high-performance rubber and plastic

For special working conditions, high-temperature resistant rubber materials have been developed to increase the upper limit of temperature resistance to 180 ℃ (such as fluororubber composite materials). This type of material not only breaks through the temperature bottleneck but also maintains excellent fire resistance (mostly reaching B1 level flame retardancy) by adding heat-resistant agents and modifiers. Commonly used in industrial high-temperature pipelines, boiler perimeter insulation, and other scenarios.

Special selection in low-temperature environments

For ultra-low temperature environments such as freezers (below -40 ℃), special formulations of low-temperature rubber cotton should be selected. This type of material ensures that it does not harden or crack under extremely cold conditions by adding plasticizers and rigid molecular structures, while maintaining a working elasticity of -50 ℃ to 70 ℃, making it an ideal choice for cold chain logistics systems.

Precautions for use and purchasing guide

When selecting, it is necessary to clarify: 1. The nominal temperature resistance is the continuous working temperature, and short-term overheating may cause performance degradation. 2. In practical applications, a safety margin of 10-20 ℃ should be reserved. 3. Long term exposure to high temperature environments requires regular inspection of material aging. In industrial projects, it is recommended to verify testing through ASTM C411 or EN 12086 standards.

A correct understanding of the temperature resistance characteristics of rubber insulation cotton is an important prerequisite for ensuring the long-term stable operation of the system. From ordinary building insulation to extreme industrial applications, scientific selection is necessary to fully leverage the advantages of material performance.
