Butyl Rubber offers excellent sealing properties against water, dust, gasses and vapour. When accurately combined with synthetic polymers and inert mineral powders, it can be blended into an homogenous, sticky and permanently flexible compound, ideal for extruding into preformed strips.

Wound into rolls on release-coated liner paper, these flexible strips are known to the industry as butyls, double-sided or butyl tapes. Butyl Tape is a single, solid material throughout - varieties featuring cross-linked rubber offer a higher adhesive take in any circumstances (including, for premium grades, under water), and further advantages in strength and elasticity, easily conforming to irregular surfaces. Optimum performance in all types of butyl can only be achieved where the combination of materials is carefully balanced and properly processed.

Because of its flexibility, long life and adhesive properties throughout, butyl tape provides a huge variety of reliable seals and joining systems. Our application pages include examples of the wide variety of applications where sealflex butyl tapes have proved their suitability.
Our industry standard butyl tape, and longest running product. Engineered to meet the ‘medium demand’ application, this tape remains one of the strongest butyls around and offers a cost-effective long lasting solution for most applications.
This butyl tape is a high performance medium cost
cross-linked adhesive sealant. Strong and grippy, it has a quick 'grab' even at lower temperatures. It offers a powerful and effective solution to many medium-high applications and offers an interim choice of higher performance grades.
Sealflex tapes are supplied (in their standard format) on a release-coated, peel-off liner paper, self wound into standard 250mm diameter rolls (the thickness of the sealant profile therefore determining how many metres are wound onto each roll). 
An enhanced version of our standard grade tape, especially formulated to offer greater adhesion to synthetic polythene sheeting, neoprene, powder coated aluminium, PVC extrusions and ceramics.
Premium grade cross-linked adhesive sealant. A very strong choice which offers the performance advantages of very high rubber content, with aggressive initial tack, high movement capacity and excellent elasticity.Good adhesion to polyethylene, polypropylene, UPVC and Hypalon® - creating a tough elastic seal.
An intumescent, 30 minutes rated, fire retardant tape for use in fire doors, screens, glazing or any construction application that requires the sealant to resist the spread of fire and toxic gases at elevated temperatures. This effective sealant medium will also prevent the ingress of water, air and noise into the joint structure.
