In high-end equipment such as modern industry, communication, and new energy, cable sealing issues are receiving increasing attention. Whether it is waterproof sealing for outdoor use of equipment or long-term sealing protection for cable outlets inside control systems, a material that is both flexible, long-lasting waterproof, and has good adhesion is needed.
In response to this demand, ELAPLUS has launched PUR 1680 two-component polyurethane sealant, designed specifically for waterproofing cable outlets and sealing equipment interfaces, combining environmental friendliness, reliability, and multi material adaptability.
Cable waterproof sealing
1、 Application pain point analysis: challenges of traditional sealing methods
In practical cable sealing applications, traditional sealing materials such as silicone rubber rings, heat shrink tubing, or ordinary epoxy adhesives often face the following problems:
Incomplete sealing: The gaps cannot be completely filled, making it easy for water to seep through.
High water absorption rate: After colloid solidification, the water absorption rate is high, leading to a decrease in performance.
Easy to age and harden: When used outdoors, it is easily affected by ultraviolet rays, rain and snow, and rapidly ages.
Poor adhesion: The adhesion with plastic, cable sheath or metal shell is not firm, and it is easy to fall off or bulge after a long time.
Difficult to cure deeply: Complex structures often cannot be fully cured due to air blockage or poor colloidal fluidity.
These issues can pose great risks to the stable operation of equipment, especially in humid, high-temperature, or salt spray corrosive environments, where performance may decrease at the slightest, and in severe cases, short circuits or system failures may occur.
