It is also to be understood that the terminology employed herein is used for the purpose of describing particular embodiments only and is not intended to be limiting since the scope of the disclosure will be limited only by the claims and equivalents thereof. Ο (N α (D GO Ό
r- σ^ (N O ^T) O (N
[53] In describing and claiming the subject matter of the disclosure, the following terminology will be used in accordance with the definitions set out below.
[54] It must be noted that, as used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise.
[55] As used herein, the terms "comprising," "including," "containing," "characterised by," and grammatical equivalents thereof are inclusive or open-ended terms that do not exclude additional, unrecited elements or method steps.
[56] It should be noted in the following description that like or the same reference numerals in different embodiments denote the same or similar features.
[57] In the embodiment that follow, there will be described as self-sealing composition for tyre puncture resistance. Specifically, there will be described the properties of the composition, the ingredients of the composition, the method of manufacture of the composition of the method of application to a tyre.
[58] The self-sealing composition is adapted for application to tires, such as motor vehicle, motorcycle, aircraft, bicycle tyres and the like for punch resistance. The composition provides selfsealing properties such that once the tyre is punctured, the composition re-seals to close or at least substantially close the puncture.
[59] The composition comprises ingredient selected by the Inventor through a process of iterative trial and error wherein the Inventor tried differing ingredients, ratios and methods for the combination to arrive at the claimed self-sealing composition having the below mentioned properties and advantages.
Properties [60] As alluded to above, the self-sealing composition is adapted for use in providing puncture resistant or puncture proof tires. As such, in use, and as will be described in further detail below, the self-sealing composition is adapted to be provided on an inner surface of a tyre to provide anti puncture properties to the tyre. In this regard, the self-sealing composition may be provided at the inner tread surface and also the inner side wall surfaces of the tyre.

Patentee Patent Attorneys Level 11, 65 York Street Sydney NSW 2000 Australia www.patentec.com.au 02 9188 9689 [61] The self-sealing composition may be provisioned during the tyre manufacture process or as an aftermarket service wherein the composition is provided for existing various tires. Ο (N α (D GO Ό
r- σ^ (N O ^T) O (N
[62] In a preferred embodiment, the self-sealing composition is applied by way of spraying, smearing or the like to an inner surface of the tyre so as to have a thickness of substantially 2.5mm to 6mm. Testing has shown that a tyre provided with the self-sealing composition of this thickness is able to withstand punctures from objects having up to 6 mm in diameter and 100 mm in length.
[63] Furthermore, no repair or remedial action is required following a penetration and a tyre provided with the self-dealing composition may be used continuously despite whether the penetrating object is left in place or pulled out.
[64] The composition is exhibits sticky and semi-solid characteristics advantageously allowing for the adherence to an inner surface of a tyre and the ability to re-seal a puncture.
[65] Testing of the composition indicates that the composition unexpectedly may have a life of up to 10 years, well outlasting the service life of the tyre itself.
[66] Furthermore, testing of the composition shows unexpected great operational temperature range tolerance ranging from -40°C to 110°C.
Composition [67] The self-sealing composition comprises three essential ingredients comprising a thermoplastic elastomer, resin, and rubber processing/extender oil.
Rubber processing/extender oil [68] In a preferred embodiment, the rubber processing/extender oil is an aromatic type processing/extender oil conforming to ASTM - 101 Type. Flowever, in other, less preferred embodiments, the rubber processing/extender oil is a naphthenic type aromatic type processing/extender oil conforming to ASTM - 103 Type or a paraffinic type aromatic type processing/extender oil conforming to ASTM - 104 Type.
Resin [69] In a preferred embodiment, the resin is a natural resin and specifically a terpene resin. Further preferably, the resin has a softening point of substantially 120°C. Flowever, in other, less preferred embodiment, the resin may have a softening point of substantially 80-110°C or 130-150°C.
[70] Furthermore, in other less preferred embodiments, the resin is a synthetic resin.
Thermoplastic elastomer [71] In a preferred embodiment, the thermoplastic elastomer is SRS thermoplastic elastomer. Flowever, in less preferred embodiments natural rubber could be employed.

Ratios Ο (N α (D GO Ό
r- σ^ (N O ^T) O (N
[72] In a preferred embodiment, the composition comprises substantially 50% thermoplastic elastomer, 40% resin and a 10% rubber processing/extender oil by weight. However, in other less preferred embodiment, the composition may comprise 40 to 49% thermoplastic elastomer, 30 to 39% resin and 8 to 12% rubber processing/extender oil by weight.
Method of manufacture [73] Turning now to figure 1, there will now be described a method 100 for the manufacture of the above described composition.
[74] The method starts at step 105 where a boiling reactor is heated to substantially 180 to 200°C.
[75] Thereafter, at step 110, the resin, thermoplastic elastomer and rubber processing/extender oil is added. In a preferred embodiment, the resin is added first followed by the thermoplastic elastomer followed by the rubber processing/extender oil.
[76] Further preferably, the resin are selected to constitute substantially 40% of the composition by weight, the thermoplastic elastomer is selected to constitute substantially 50% of the composition by weight and the processing/extender oil is selected to constitute substantially 10% of the composition by weight.
[77] For example, when making a batch of substantially 100 kg, substantially 50 kg (+/-3 kg) of thermoplastic elastomer, 40 kg (+/-3 kg) of resin and 10 kg (+/-3 kg) of rubber processing/extender oil will be used.
[78] Once the ingredients have been added, the temperature of the boiler is increased to substantially 230°C at step 115.
[79] At step 120 of method 100, the reactor is maintained at the elevated temperature for substantially one-hour, or at least until all of the granules of the ingredients have melted.
[80] At step 125, the temperature of the reactor is decreased to substantially 180°C. While at this decreased temperature, at step 130, the decreased temperature is maintained for substantially two hours while the ingredients are mixed.
[81] At step 135 the colour and viscosity of the composition is checked. For the colour, the colour is checked whether the colour is between dark yellow and dark brown.
[82] At step 140, being substantially three hours from the addition of the ingredients, the composition is poured from the reactor into a container.
Method of application [83] As alluded to above, there will now be described the method of application of the self-sealing composition described above to an inner surface of a tyre.

[84] The inner surface may be an inner tread surface of the tyre so as to protect the tyre against direct punctures, such as from sharp objects on a road surface. Furthermore, the inner surface may alternatively, or additionally be a sidewall inner surface of the tyre so as to provide protection from lateral foreign objects including ballistics. [85] Preferably, the self-sealing composition is applied to a thickness of substantially 2.5mm to 6mm. [86] Application of the self-sealing composition may take the form of spraying the self-sealing composition, smearing the self-sealing composition and the like.
