PREFORMED BUTYL IN STRIP
Effective Sealing for Construction, Automotive and More
Preformed butyl strip is a self-adhesive sealing tape made primarily from butyl rubber. It comes in rolls or strips, making it easy to apply without the need for special tools. Thanks to its high adhesion and flexibility, it adapts well to various surfaces and environmental conditions.
COMPOSITION

Support (A): Butyl extruded strip
Liner (C): Siliconized paper Film
KEY FEATURES

Compatibility: Suitable for metal, plastic, glass, concrete, wood, ceramic, etc.
Elasticity: Flexible, does not become brittle over time.
Tightness: 100% waterproof against water, air and dust.
Chemical resistance: Good resistance to diluted acids, salts and atmospheric agents.
No curing: Does not require drying time.
Gap filling: Excellent performance on irregular or rough joints.
Non-migratory: Does not stain adjacent surfaces.
Dimensional stability: Does not deform or shrink over time.
PROS AND CONS, WHY CHOOSE IT?
✅ Advantages
- Self-adhesive without heat or tools: Applied directly without guns, heat, or mixing. Saves time on-site or in workshops.
- Vibration damping: Its flexible structure helps absorb vibrations – ideal for vehicles, machinery, or HVAC systems.
- Compatible with multiple materials: Adheres perfectly to metal, plastic, wood, glass, concrete, etc.
- Does not dry or crack over time: Unlike some sealants, butyl remains elastic for years, even outdoors.
⚠ Disadvantages
