The Main Safety Features of PunctureSafe HighPerformance, High Speed Grade

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.

Seals only the smaller, less harmful punctures
PunctureSafe does not have any of the failings that are inherent in many previous and most of the current products available on the market today. Traditional tyre sealants contain large chunks of rubber particles that are incapable of sealing small holes in a tyre, yet they will readily seal a large and dangerous hole or gash. Conversely, Puncturesafe contains only small rubber granules and synthetic fibres that when interlocked in a puncture are extremely strong. PunctureSafe will only seal punctures in the tread area that are safe to seal and which have been caused by puncturing objects no larger than 6mm in diameter and only if the hole is shrinking in size because neither excessive tyre rubber has been lost or cord damage has occurred. These small punctures account for 95% of today’s punctures in high speed vehicles. Any larger puncture, either with or without cord damage and PunctureSafe will just slowly bleed through the hole giving a controlled deflation. In these circumstances air pressure loss in the tyre will either stop or slow down at the lower pressures of 10 to 15 PSI, dependent on the severity of the puncture. This slower loss of air pressure prevents damaged rims and enables the driver/rider to maintain control and possible continuation of the journey, thereby removing the vehicle from a potentially dangerous location. PunctureSafe will not seal a puncture in the sidewall because the sidewall is much thinner and more flexible, therefore in the event of sidewall punctures a controlled deflation will usually occur.

Gives better coverage throughout the inner tyre
Traditional tyre sealants do not cover 100% of the crown area in a high-speed tyre – at best they usually only cover 60% which becomes less as the vehicle increases in speed, because more of the tyre sealant is driven to the centre area creating a mound that can cause vibration at the higher speeds. One of the components of PunctureSafe is a polymer gel (FlexxaGel™) which has an affinity to adhere to rubber even in a vehicle moving at very high speed. Although “FlexxaGel™” behaves like a glue and has properties similar to glue, it is not a glue. When the lateral movement of a vehicle throws the excess PunctureSafe over the crown area and sideways up the inner sidewalls of the tyre, the adhesive properties of “FlexxaGel™” allows PunctureSafe to cling evenly over more of the inner tyre surface at all speeds. Although the gel will immediately cover the whole of the crown and shoulder areas, a settling in period of 1500+ miles is required to activate the FlexxaGel™ for sidewall coverage. This maintained inner tyre coverage at speed gives added heat dispersion to the rim via sidewall coverage due to conduction. Heat dispersion to the rim allows a cooler inner tyre and cool tyres are less susceptible to punctures. The gel’s ability to seal porosity leaks over the inner tyre helps maintain tyre pressure, the tyre becomes safer with the added bonus of extended tyre life. Incorporation of “FlexxaGel™” into the process also gave the finished sealant incredible elastic properties enabling it to stretch and flex, covering more of the inner tyre with increasing speed. (The PunctureSafe gel will relax in a stationary vehicle covering less of the inner tyre) “FlexxaGel™” is exclusively manufactured at our Devon facility and is one of our most closely guarded trade secrets.

Withstands the heat and stress in a high speed tyre
Unlike traditional tyre sealants, PunctureSafe’s concentrated polymer gel formulation containing over a dozen technically advanced polymers, rubber and fibre fillers, will not separate, ball up, or dry up – thereby withstanding the extreme heat and centrifugal forces that can be created in the hostile environment of a very high speed tyre. In a closely guarded proprietary process, PunctureSafe is manufactured to stay liquid in a high speed tyre for the entire lifetime of the tyre, irrespective of its use. Compared with traditional tyre sealants, the Thixotropic qualities of the PunctureSafe polymers allows change from a very viscous gel to a thin liquid when the vehicle is at speed, yet returning immediately to a viscous gel when the vehicle comes to rest, and it is this feature that helps stabilise the polymers from eventual breakdown. Many traditional tyre sealants pool on the bottom of a tyre in a stationary vehicle causing vibration with each forward movement, but PunctureSafe stays firmly coated over the inner tyre. PunctureSafe’s ability and performance is not diminished with speed, distance or time.

These qualities alone put PunctureSafe in a league of its own
