How to choose between butyl tape and rubber tape?
Butyl tape and rubber tape are two common sealing materials, but their application scenarios also differ significantly due to differences in composition and performance. Here are their differences and typical applications:
| Characteristics | Butyl tape | rubber tape |
|---|---|---|
| Main components | Butyl Rubber | Natural rubber or synthetic rubber |
| Viscosity | High viscosity, strong self adhesiveness | Medium viscosity |
| Weather resistance | very good | general |
| Tightness | Excellent airtightness and water tightness, suitable for long-term sealing | Good elasticity, but long-term sealing may be weaker than butyl tape |
| Temperature range | -40°C ~ 90°C | -20°C ~ 80°C |
| Chemical resistance | Acid and alkali resistant, solvent resistant | Generally (some synthetic rubbers are oil resistant and corrosion-resistant) |
| Lifetime | 10-20 years (long-term stability) | 5-10 years (susceptible to environmental impact) |
Application scenarios
Butyl tape
Construction field
◆ Waterproof sealing of roofs, gutters, and skylights;
◆ Filling of joints between door and window frames and walls;
◆ Moisture proof treatment of steel structure joints.
Automotive field
◆ Windshield and headlight installation sealing;
◆ Rust prevention of body sheet metal joints;
◆ Waterproof battery pack for new energy vehicles.
Special Scene
◆ Edge sealing of solar photovoltaic panels;
◆ Repair of waterproof layer in underground engineering (tunnels, pipe galleries)
Rubber tape
Industrial sector
◆ Temporary sealing of pipeline flanges;
◆ Seismic and buffering cushion layer for mechanical equipment;
◆ Adhesive repair of conveyor belt joints.
Electronic and Electrical
◆ Cable insulation protection;
◆ Dustproof and moisture-proof packaging of electronic components.
Everyday Use
◆ Temporary repairs (such as water pipe leaks);
◆ Home anti slip mats, door and window gap filling.
Choose Suggestions
Choose butyl tape:
for scenarios that require long-term waterproof sealing, resistance to extreme temperatures or chemical corrosion (such as roofs, car seals).
Choose rubber tape:
for scenarios that require elastic cushioning, temporary repairs, or insulation (such as industrial equipment shock resistance, cable wrapping).
Construction points
Butyl tape:
The surface should be clean and dry, and the adhesive strength should be stronger after compaction to avoid repeated tearing.
Rubber tape:
some types need primer, and anti-aging formula is recommended for outdoor use.
