What are the common problems in the storage of silicone rubber heaters?

Silicone rubber heaters may encounter the following common problems during storage:
Environmental factors
Humidity impact: If the storage environment is humid, moisture may condense on the surface of the silicone rubber heater, which will affect its electrical insulation performance. Long-term exposure to high humidity may also cause the metal parts inside the heater to rust, thus affecting its service life and performance.
Temperature problem: Too high a temperature may accelerate the aging of the silicone rubber material, resulting in a decrease in its elasticity and insulation performance; too low a temperature may make the silicone rubber hard and brittle, prone to cracks, and also affect the performance and reliability of the heater.
Dust and impurities: Dust and impurities in the storage environment may adhere to the surface of the silicone rubber heater. If dust and other impurities accumulate too much, it may affect the heat dissipation effect of the heater, causing the local temperature to be too high, thereby affecting its performance and life.
Physical damage problem
Extrusion deformation: If the silicone rubber heater is squeezed during storage, it may deform. Especially for some irregularly shaped or thinner heaters, extrusion may cause the internal heating wire or circuit to shift or break, affecting the heating effect or even making the heater unable to work properly.
Collision damage: During transportation or storage, if the silicone rubber heater collides with other hard objects, it may cause surface damage, internal component damage and other problems.
Material aging problem
Natural aging: Even under normal storage conditions, silicone rubber materials will naturally age over time. It manifests as silicone rubber becoming hard, brittle, losing elasticity, and cracks may appear on the surface, which will reduce the flexibility and reliability of the heater, and may also affect its insulation performance and heating efficiency.
Chemical influence: If there are certain chemicals in the storage environment, such as acids, alkalis, organic solvents, etc., they may react chemically with silicone rubber materials, accelerating the aging and damage of silicone rubber.
Electrical performance problems
Degradation of insulation performance: In addition to environmental factors such as humidity, long-term storage may also cause the insulation performance of silicone rubber heaters to degrade. This may be caused by aging of silicone rubber materials, moisture or damage to the internal circuit. Degradation of insulation performance may cause safety problems such as leakage, endangering the personal safety of users and equipment safety.
Circuit failure: During storage, the circuit inside the heater may fail, such as broken heating wires and loose solder joints. This may be caused by temperature changes, mechanical vibrations, etc., which can cause the heater to not heat properly or heat unevenly.
