|Not unlike the UV rating of sunblock creams on humans; the UV number applied to Plastics being exposed to the sun's UV rays, indicates the snorkel material's resistance to UV damage - and consequently, life of the snorkel.
The higher the UV rating number, the greater the protection, hence advanced component life can be expected.
It is not uncommon to see Safari snorkels that are over 20 years of age, still looking great with zero cracking and no discernable hardening. This is what consumers demand!
The biggest problem with inferior products sourced from China is that the base material used is at best only a fraction of the UV rating required for long life and crack-free operation. Some manufacturers even tout that they source materials from quality international suppliers such as Mobil Exxon - but fail to warn the consumer that these products typically have a UV rating of only 8. This means that unless the snorkel products are kept out of the sunlight, they will degrade rapidly and require replacement well within the life span of the vehicle that the snorkel is fitted to.
In Australia, no reputable supplier of raw material would claim such a product to be suitable for continual exposure to the sun's UV rays over many years in an environment such as an Australian summer.
The result of continually exposing a UV8 rated material to an Australian summer is best demonstrated by inferior Chinese made, home use, children's climbing equipment. If left outside in the sun across an entire summer, any parent can attest to the fact that at the end of the second summer at the most , it normally needs to discarded due to dangerous cracks having formed.
To most consumers, the thought of replacing a snorkel twice or even three times during the life of the vehicle is almost inconceivable - because they have never experienced a situation such as this in the past with Australian manufactured snorkels.
In order to increase the rating of even quality raw material, from its base number of UV8, to the UV20 required for satisfactory life, the Australian plastics industry has learnt just what ADDITIVES are required.
Not only that, how to correctly COMPOUND - as opposed to simply mixing these additives with a quality raw material, with its poor structural consequences (see Laboratory Report).
In short, cheap Chinese manufactured copy snorkels, even if made from a quality supplier's raw material with a UV8 rating, are simply not going to cut it in an Australian, (or African, if it comes to that) environment.
To obtain the life of a Safari snorkel, the snorkel must be molded, in Australia, from the best plastics molding company, in a high quality UV20 rated compounded material.
