Preformed Butyl Strip Sealant
1. Assembly Strip Brief
A clean, compressible non-curing strip installed between mating surfaces in panel, glazing, duct, vehicle, caravan and equipment-housing assemblies.
2. Configurable Profile Matrix
| Form | Strip, rope, pad or die-cut profile |
|---|---|
| Compound | Butyl rubber and polyisobutene blend |
| Adhesive faces | Double-sided; single-sided by inquiry |
| Colours | Black, grey, white or customized |
| Liner | Release paper, film or optional two-liner format |
| Numeric dimensions | Defined from joint geometry |
3. Hidden Joint Uses
A clean, compressible non-curing strip installed between mating surfaces in panel, glazing, duct, vehicle, caravan and equipment-housing assemblies. It controls air, water, dust and vibration without wet dispensing.
4. Strip Forming
Mixing determines softness and tack; extrusion or calendering establishes cross-section. Liner application and spool packing support repeatable assembly handling.
5. Compression Qualification
Approve dimensional tolerance, liner release, compression height, peel, shear, ageing and sealing in the final joint. Custom shapes require a physical fit trial.
6. Joint Drawing Inputs
Send groove or overlap drawing, gap, target compression, colour, liner, roll or spool format and OEM packing. Lock the formula for repeat orders.
7. Assembly Questions

Approve dimensional tolerance, liner release, compression height, peel, shear, ageing and sealing in the final joint. Custom shapes require a physical fit trial.
8. Preform-Control Trend
Assembly plants increasingly purchase preformed profiles from joint drawings to reduce wet-sealant variation on production lines.
