Shockproof protection for a camera, a covering for a fragile smartphone charging cable, a hook for towels: Sugru® can provide all this, and 1000 things more. Sugru® is available in many colors and its possible applications are virtually infinite, ranging from fastening and bonding to sealing, insulation, closing cracks and holes and protection or marking. By the way, the brand name Sugru® is derived from the Irish word for “play.” That’s fitting since there are no limits to your imagination when you use the special mouldable adhesive.
Inventor Jane ní Dhulchaointigh didn’t know any different when she was growing up on a farm: broken items were repaired. When she moved to the city, she had to get used to the fact that a lot was thrown away and bought new. She studied product design at the Royal College of Art – and noticed that the focus there, too, was primarily on developing new products rather than repairing old ones. She considered. She experimented. And then came the day when she mixed silicone and sawdust. The result was amazing. It looked like wood, but bounced like a table tennis ball.
To further develop her idea, ní Dhulchaointigh and her husband James Carrigan, together with British entrepreneur Roger Ashby, brought two retired silicone specialists out of retirement. A total of 8000 hours in the lab, about 5000 experiments, and six years total were needed to develop Sugru® before the patent was granted for the mouldable multifunctional adhesive, which combines the strength of a high-performance adhesive with the flexibility of rubber. With Sugru®, materials such as aluminum, steel, ceramics, glass, wood and many others can be permanently joined, and in most cases removed from a surface with a sharp knife.
1. Take it out of the package and knead it
This makes Sugru® flexible, soft and super mouldable.
2. Mold and create
With Sugru®, you can now repair, seal, cushion, adhere, improve, embellish and much more.
3. Dry for 24 hours and use for years
Sugru® turns into a durable but still flexible silicone rubber.
When Sugru® is removed from the package, it remains mouldable for about 30 minutes. It takes 24 hours for it to harden and develop a rubbery surface. After that, it holds its shape, is elastic and waterproof, and withstands temperatures from -50°C to +180°C. Time magazine agreed that these are excellent qualities when it placed Sugru® at number 22 out of the world’s 50 best inventions of 2010 (by the way, the iPad was number 34). And the European Patent Office (EPO) also saw Sugru® as a breakthrough invention, honoring it with the European Inventor Award in 2018.
Over 2.5 million users worldwide are now part of the Sugru® fan movement. No wonder, since the smart compound fits perfectly into a new awareness of sustainability. Repairing things or making them yourself is not a short-lived trend; it constitutes a conscious use of resources. ní Dhulchaointigh took advantage of this public awareness when she was developing Sugru®. Shortly before the market launch in 2009, she and Tom Dowden, the company’s first permanent employee and current research director, consulted with a 150-member user group. Only through their continuous feedback on improvement of the product could Sugru® become what it is today.
The flexibility and possible applications of Sugru® won over tesa as well. In May 2018, tesa SE acquired London-based FormFormForm Ltd., and with it, Sugru®. It’s a win-win situation for both companies: tesa expands its product range in the field of intelligent fastening solutions with a product that can be used in many different ways, and especially appeals to young target groups. And FormFormForm Ltd., with around 60 employees, benefits from our infrastructure and the strong international tesa® brand.
