How to Reduce the Aging Factors of Rubber-Plastic Insulation Materials?
rubber-plastic insulation materials are elastic closed-cell materials with excellent properties such as flexibility, bend resistance, cold resistance, heat resistance, flame retardancy, waterproofing, low thermal conductivity, vibration damping, and sound absorption.
The primary factors contributing to the aging of rubber-plastic insulation materials can be divided into two categories:
- Insulated Medium Factors – Refers to alternating temperature changes of the medium being insulated.
- Environmental Factors – Includes ozone exposure, UV radiation, and alternating temperature and humidity conditions. Among these, environmental factors are the main cause of aging in rubber-plastic foam insulation materials.
Compared to the relatively stable conditions indoors, outdoor equipment and pipelines are exposed to stronger UV radiation, higher ozone concentrations, and more drastic temperature and humidity fluctuations, significantly accelerating material aging.
To delay aging, AF/Armaflex® Jacketing Systems provide specialized protection for different outdoor environments:
- AF/Armaflex® Jacket S350 – Multi-layer aluminum-plastic composite material.
- AF/Armaflex® Jacket R – High-density rubber polymer coating.
- AF/Armaflex® Jacket D – Black specialty fiberglass fabric surface.
These solutions enhance the service life of AF/Armaflex® rubber-plastic insulation materials in harsh outdoor conditions.
