Tin Soldiers into new territories

No longer is tin subjected to the humble canned foods that stock our supermarket shelves as the metal is given a new lease in life, largely through new technologies. Its use in technology began early in 2000 when US EPA banned the use of lead solders in electronics, sending tin solder up overnight. Tin has seen strong signs of growth, partially due to the consumer thirst for electronics, particularly mobile phones and computers, which have contributed to the drive in demand for tin. Risks associated with the main applications of electronic solders and tinplate suggests new assembly technologies as well as lower coating weights could negate usage. The balancing act remains on the prospects for new applications in tin chemicals and energy related technologies such as lithium ion batteries and steel alloys.

The switch to lead-free soldering around the world has added to the commodity growth as circuit boards used to be contained with 6-63% of tin, currently close to 96-99%. If we make a link to the crazed frenzy for electronics produced by mavens such as Apple, it clearly suggests that tin is a highly desired commodity and opens up the challenge for whether Australia can deliver its supply.

Tin’s progression goes beyond consumer products where its use can be found to help animals with the development of antimicrobial activity in tin that provides healthcare solutions. Healthcare products that are being developed work in preventing and treating skin diseases in bovine (cattle), equine (horses), canine (dogs) and other animal sectors. Tin has become a valuable resource where its purpose is constantly being redefined. While its future remains poised and acknowledging the importance of generating investment in the tin industry, ITRI has moved towards ensuring the industry remains stimulated by funds through creating a members association to assure global tin consumers work is securing long-term tin supplies.

Protecting smiles thanks to Tin

The wonders of tin’s usage is not known to many as the compound is found within toothpaste and approved by the US Food & Drug Administration with levels up to 0.4% as well as the American Dental Association approving up to 8% of tin fluoride in topical treatments. Oral healthcare is becoming an attractive growth sector for tin in the medium terms and this is resulting in patent activity by major consumer conglomerates such as Procter & Gamble (‘Crest Pro-Health’ and ‘Oral-B Pro-Expert’), Unilever Colgate – Palmolive and Gaba International which use tin salts in their production.  This also raises a question of the amount of tin that can be supplied as there is an increase in usage of toothpastes worldwide and furthermore in developing nations.

Tin’s technical name known within the oral hygiene industry is stannous fluoride which provides the benefit of effective protection against plaque and cavities and acts an antimicrobial agent which fights against gum diseases such as gingivitis.  Stannous fluoride’s effectiveness results in making tooth enamel stronger and is seen to offer more protection than other fluorides such as sodium fluoride and sodium monofluorophosphate, commonly found in many toothpastes and oral care products.  The apparent health benefits suggest the many layers of use that tin provides in day-to-day life where consumer perceptions will move away from what they associate the common element with.
