In building and industrial thermal insulation projects, systems typically need to operate continuously for extended periods. The performance stability of insulation materials directly impacts energy efficiency and maintenance costs. Rubber and plastics (RPMs), as widely used flexible insulation materials, require careful consideration of their stability during long-term system operation, a key focus in engineering selection and design. This article analyzes the performance of RPMs under long-term operating conditions from the perspectives of material properties and practical applications.

From a material structure perspective, RPMs are closed-cell elastic materials with uniform and independent internal bubble structures. This structure helps maintain relatively stable thermal conductivity during long-term use, reducing performance fluctuations caused by air convection or structural changes. In continuously operating systems, stable thermal performance is crucial for ensuring energy-saving effects.

Regarding mechanical performance stability, RPMs possess a certain degree of flexibility and resilience. During long-term operation, systems may experience temperature changes and slight vibrations. If the material is brittle or loses elasticity, cracking or detachment may occur. Within its applicable temperature range, RPMs maintain a relatively stable elastic state, which is beneficial for long-term adhesion to pipe and equipment surfaces, maintaining the integrity of the insulation layer.

Moisture and condensation resistance are equally crucial for long-term operating systems. In systems with extended operating cycles, moisture intrusion gradually weakens the performance of insulation materials, even leading to corrosion or mold growth. The low water absorption rate of rubber and plastics makes them less prone to significant performance degradation due to moisture during long-term use, contributing to the stability of the system's operating environment.

From a construction and maintenance perspective, the stability of rubber and plastics in long-term operating systems is also reflected in their adaptability to installation quality. Rubber and plastics are easy to cut and cover, allowing for good continuous coverage during construction. In later maintenance, if localized areas require repair or replacement, the handling of rubber and plastics is relatively convenient, helping to reduce the impact of system maintenance on overall operation.

It is important to note that the stable performance of rubber and plastics in long-term operation depends on proper selection and standardized construction. Prolonged exposure to environments exceeding their applicable temperature range, or compression or damage during installation, will adversely affect their stability. Therefore, the thickness and specifications of the rubber and plastics should be rationally determined during the design phase, taking into account the system's operating conditions.

Overall, rubber and plastics exhibit good thermal stability, mechanical adaptability, and moisture resistance in long-term operating systems. Provided the usage conditions are met and proper construction is followed, rubber and plastics can continuously provide insulation during long-term operation, offering relatively reliable thermal support for building and industrial systems. This is one of the key reasons why they are widely used in various long-term operating projects.
