Zhonghao butyl strip sealant is a preformed tacky sealing strip for assembly joints that need a clean, compressible and non-curing seal.
The strip can be placed between two surfaces before compression, helping control air, water, dust and vibration in panel, glazing and vehicle applications.
Custom width, thickness, shape, color and packing can be arranged for manufacturers, contractors and replacement part suppliers.
1. Product Introduction
Butyl strip sealant is different from exposed repair tape because it is usually hidden inside the joint. It is placed on one surface, covered by the mating part and compressed during assembly.
This form is useful for metal building panels, ventilation ducts, glass frames, automotive trim, caravan parts, equipment housings and other joints that need a soft seal without liquid curing time.
Zhonghao can adjust softness, tack and dimensions so the strip fits the required groove, overlap or compression design.

3. Product Feature And Application
Preformed And Clean
Workers can place a measured strip without dispensing wet sealant, helping keep assembly lines cleaner.
Compressible Joint Filling
The soft butyl body fills small gaps after pressure is applied between panels, frames or trim parts.
Water Air And Dust Control
It supports sealing in metal buildings, ducts, vehicles, glazing and equipment housings.
Non-Curing Flexibility
The material stays pliable, which helps the joint tolerate small movement and vibration.
4. Production Details
Compound Consistency
Mixing control affects tack, softness, temperature behavior and long-term sealing.
Strip Shaping
Calendering or extrusion should maintain a stable cross-section for predictable compression.
Liner Application
A clean liner prevents blocking and allows operators to handle the strip during assembly.
Roll Or Spool Packing
Packing style can be matched to manual installation, workshop benches or production line dispensers.
5. Product Qualification
Quality checks should include dimension tolerance, tack, peel adhesion, shear behavior, liner release, compression sealing, aging and appearance.
Buyers should verify compression height and contact area in the final assembly before confirming the production size.
6. Delivery Shipping And Service
Prototype strips can be supplied for assembly trials. Bulk orders can be packed as rolls, spools or private label cartons according to handling needs.
Zhonghao can support repeat orders with fixed formula, batch traceability and export carton marking.

Does It Cure Hard?
No. Butyl strip sealant stays pliable and tacky after installation.
Can The Shape Be Customized?
Yes. Width, thickness and selected shapes can be customized according to the joint.
What Should Buyers Test?
Check compression, adhesion, liner removal and sealing in the final assembly.
Can Zhonghao Supply OEM Packing?
Yes. Rolls, spools, boxes and labels can be prepared for OEM or distributor orders.
