Puncture Safe Explained
How it works
The advanced technological sealing capabilities of PunctureSafe stand on guard to seal punctures as they happen. When a tyre is punctured, PunctureSafe coats the surface of the penetrating object, thus preventing air loss.
When the puncturing object is removed, the rubber recovers and the wound immediately closes, escaping air siphons PunctureSafe into the puncture. The fibres entwine to create a clot that prevents any additional air from escaping. As the rubber recovers, the puncture closes and the strength of the tyre holds the seal in place. The specialised polymers and fibres form the seal, thereby producing an airtight seal.
The small amount of PunctureSafe that penetrates through the puncture, past the belts and out through the tread area is referred to as a seal. Once exposed to the atmosphere, the seal begins a systematic cure, another proprietary attribute from the PunctureSafe R&D Team. As the seal cures, it makes a positive secure seal that is impervious to water, which totally protects the belts and inner casing from outside contaminants and corrosion.
PunctureSafe's proprietary formulation is one of our closely guarded secrets, which allows PunctureSafe to withstand heat and the shear forces created within a rotating tyre. The thixotropic polymers stretches and recovers under mild to severe exposure of the adverse forces and continuously clings to the inner tyre. The ability to coat the inner surface against adverse conditions and centrifugal force is the reason that PunctureSafe will not adversely affect a balanced tyre assembly and does not lose the ability to provide protection for the tread life of the tyre.
PunctureSafe's abilities & performance is not diminished with speed, distance or time.
If the tyre's integrity is weakened to a point where the tyre and casing are unsafe, PunctureSafe is designed to bleed and slowly release air pressure in a controlled way if the puncturing object has severely damaged the inner structure.
PunctureSafe will not hide or mask a dangerous puncture regardless of how small the damage may be.
If the integrity of the casing has been breached and safety becomes an issue PunctureSafe is designed to allow air to escape in a controlled manner.
Coating and conditioning
PunctureSafe coats and clings to the inner tyre conditioning the inner surface, eliminating air migration caused by porosity and bead leaks.
In order for PunctureSafe to function, the vehicle should be driven approximately 3 to 5 miles. This initial driving allows the tyre to warm up and for PunctureSafe to distribute. PunctureSafe will cover the crown area in the first few miles but it will take another 1500+ miles for the FlexxaGel to activate giving more coverage of the sidewall. Unlike conventional tyre sealants, PunctureSafe has been developed to prevent migration from the sidewalls and the tread area at high speeds. Once the initial driving/usage period has been attained; PunctureSafe will cover more of the inner surface of the tyre.
PunctureSafe is a proprietary liquid coating that never deteriorates within the tyre and will continuously stand on guard to protect tyres against air loss for the legal tread life of the tyre.
Positive secure seal
When a tyre is punctured, PunctureSafe is forced against and around the puncturing object by the inner air pressure, thereby preventing air from escaping. If the puncturing object is thrown out of the tyre by centrifugal force or is pulled out, the inside air forces PunctureSafe into the puncture and immediately stops air loss. Special fibres entwine, forming a seal, then as the rubber recovers, aided by the tyre flexing as it rotates, the inner air pressure forces the seal well into and through the puncture. Once PunctureSafe is exposed to the outside air, a curing process begins. The cured seal extends well into the puncture, thus providing a seal that is impervious to water (rain, snow, mud, etc.). As this seal cures, it is transposed into a permanent rubberised seal, protecting the inner casing and steel belts against contaminants entering the puncture.
Outstanding at sealing punctures
PunctureSafe’s makeup is 80% polymer and 20% liquid which means it is a very high solids content and dries to a flexible rubbery plug in the puncture without any shrinkage. The polymer gel suspends a special mix of highly fibrillated fibres and granulated rubber fillers which contribute to Puncturesafe’s sealing abilities, so once the seal is in place it is permanent and will not fail at a later date.
