Magic Rubber Flexible Rubber Potting Compound for Waterproof Electrical Sealing

Magic Rubber is a fast-curing, two-component flexible rubber potting compound designed for electrical insulation, waterproof sealing, and mechanical protection. After mixing, it cures at room temperature into a flexible, elastic rubber that helps protect electrical connections from water, dust, corrosion, movement, and mechanical stress.

Unlike hard epoxy potting compounds, Magic Rubber remains flexible and re-enterable. This makes it a strong choice for applications where the connection needs long-term protection, but future access may still be required.

Flexible rubber potting compound for electrical insulation and sealing
Provides mechanical protection for connections, boxes, closures, and terminal blocks
Waterproof IP68 protection in proper casings
Re-enterable after curing, unlike permanent epoxy encapsulation
High dielectric strength for low-voltage electrical installations up to 1kV
Fast cross-linking at room temperature
Suitable for molds, gaskets, nuts, closures, boxes, and cable connection protection
Suitable for saltwater and chlorinated environments
REACH and RoHS compliant

Why Choose Magic Rubber?

Magic Rubber is ideal when a standard dielectric gel may be too soft, but a hard epoxy may be too rigid or permanent. It creates a formed rubber body that adds mechanical structure while still remaining flexible and re-enterable.

This makes it useful for electrical boxes, terminal blocks, cable closures, junction boxes, outdoor enclosures, small molds, gaskets, and components exposed to moisture, water, dust, corrosion, saltwater, chlorinated environments, movement, or mechanical stress.

Elongation at break: approximately 350%
Tensile strength: approximately 2.9 MPa
Tear resistance: approximately 8 N/mm
Continuous working temperature: -60°C to +200°C
Degree of protection: IP68 in proper casings

Common Applications

Waterproofing electrical connections
Protecting terminal blocks and junction boxes
Flexible potting for low-voltage electrical components
Mechanical protection for cable connections and closures
Outdoor, marine, humid, and chlorinated environments
Small molds, gaskets, nuts, and custom rubber fills
