Now, that’s probably not a question that you have ever asked yourself, but it is in fact an incredibly interesting one. It is thought that condoms are the third most popular form of contraception. They are however the only method that prevents the transmission of sexually transmitted infections. If you are concerned that you may have put yourself at risk of contracting an infection you can order Home StI kits from companies such as bexley sexual health that you can complete and return in the comfort of your own home.
Advertising for these products have increased over the years as more and more people start to think seriously about their sexual health and in the US alone it is thought that around 450 million condoms are sold annually.
Condoms are most commonly made from latex although there are others made from polyurethane which tend to be used by those with latex allergies although their effectiveness at reducing the transmission of sexually transmitted infections is not as widely tested as those made from latex.
Here is the process for making the trusty condom:
- Raw materials – the raw materials namely rubber latex is collected by taking the raw product from the relevant plants
- Compounding – this is a process by which various chemicals are added to the raw liquid latex and blended into a paste.
- Storage – The latex and chemical compound is then stored in large barrels for around 7 days . It is during this time that vulcanisation of the rubber takes place and strengthens the latex. The air that can become trapped during the compounding process is then allowed time to escape.
- Dipping – the compound is added to a machine that has glass rods in the shape of a condom suspended above it. These rods are repeatedly dipped into the compound mixture until the thickness of the latex layer is achieved. They are then moved for drying as they are removed from the glass rods and trimmed at the base.
- Tumbling – following this they are placed in a tumbling machine where they are coated with a layer of talc or talc like substance to prevent them from sticking to themselves.
- Testing – after they have been left to rest for a number of days they will be batch tested to ensure that no leaks occur and that they meet the strength standards. They are put through an inflation test where air is blown into the condom until it bursts and they must exceed a stretch of over 1.5 cubic feet in order to pass this testing. The next test is for water leakage where they are filled with 300 ml of water and inspected for the tiniest of holes.
- Packaging – the condoms are now ready to be sent for packaging and then finally batched together and sent for delivery.
