- It is surprising to know that the main ingredient in honey that Crocs shoes you bring in the top of the material used in high-end cars.
Automotive industry is currently used mostly aluminum and complex compounds, they can not be linked with technology typically molten solder. Instead, they are attached with adhesive back without losing strength and durability can hold even at high speeds and pressures. This makes industrial adhesives - composed of chemicals such as polyolefins are the main components of Crocs shoes and tennis racket strings - the top ten list of the materials used in the car manufacturing industry.
Automotive adhesives market now reaching 2.6 - 3.9 billion, accounting for less than 10% market share in the global adhesives. But experts forecast, the average amount of glue used on a vehicle can increase by at least one third in the next 5 to 10 years, compared with 15kg mark now.
Along similar sealing material can fill small gaps in the different joints of a vehicle, structural adhesives have more sustainable effects and reinforcing the mount bearing parts and the components such as doors, and the resistance.
It can prove that their products bring to glue different characteristics and can easily participate in the production process, to achieve good profits. Suppliers such as Henkel, Atlas Copco PPG and thanks to the ability to provide this type of adhesive can absorb the shock of a collision and minimizes noise emitted, so they let her push prices higher and more profitable. The laws of more stringent emission in the main market mean that cars have become more fuel efficient and less polluting, but in many cases cars have lighter than average weight in prior to 1.400kg.
Henkel, manufacturers of the world's largest adhesive disposed branched simple adhesive industry to focus on more complex products and dedicated for cars, aircraft or mobile phone. Profits of branching this adhesive technology stood at 16.5% in the first quarter, exceeding the 14.9% average profit of all the ramifications.
Special Needs
Although retail car market in Europe this year witnessed a decline for six consecutive years by the austerity policies of the government and unemployment held constant, the entire auto sales demand could increase 28% and reached 102 million units in 2018 due to the growth in Asian markets and North America, according to research firm IHS Automotive.
"We do not buy these types of glue available that work very closely with the manufacturer of specialty adhesive complex" - Michael Zuern, technical leader of Merc said material.
Atlas Copco companies from Sweden joined segments adhesive for automobile in 2011 through the acquisition of the German company SCA-Schucker. Mats Rahmstrom, head of business area Industrial Technique's assessment: "This is one of the product areas with the strongest growth since it is driven by new technologies all the time and attention new concept of vehicle manufacturers. "
Weight loss goals
"Adding power makes you faster on the straight line, reducing weight makes you faster on all roads" - Colin Chapman, founder of Lotus car company has confirmed. Not only in the field of production car racing, light weight has become the main trend in the automotive industry. The manufacturers expect business as Alcoa aluminum plate number will triple by 2015, when the material is stainless steel is preferred for the door, and the block and cylinder head.
Mlekusch Bernd, chief technology developed by Audi, said the proliferation of lightweight materials can lead to the amount of adhesive used on a Audi car length increased up to 150 meters in the next year compared with 100 current meters. Another interesting thing is the amount of adhesive used for car manufacturers usually only notice the total length rather than weight.
By increasing the adhesive strength of the tire, the vehicle can absorb the bumps better and the car noise is reduced. It also makes for better handling and help absorb the impact of a crash.
New CTS sedan GM 118 meters using adhesives, than the length of a football field, to make sturdy supports over 40% compared to the predecessor model. Using aluminum for the doors also help to reduce the weight of the CTS 25kg.
Pros and cons
Andrew Christie, in product management solutions division of PPG materials in Germany said that the glue hardens cracks on the market can absorb impact energy more efficiently than standard gel or even spot welds. One of the keys to surviving a crash vehicle structure can be hit by a sudden change impacts to the human body.
Many parts of the Audi R8 is tied together by special glue to withstand vibrations on the track and fierce heat.
Initially, many car manufacturers did not have the courage to admit that some parts of the car and details should be mounted with glue. Now, however, auto manufacturers and suppliers of adhesives work with research institutes such as the Fraunhofer Institute in Germany to try to cure at low temperature glue and glue will ensure that the correct distribution by robots.
However, the adhesive is not necessarily perfect. In 2010, Ferrati brand recall 1,248 cars Fiat 458, after determining that the special glue used to attach the heat shield inside the wheel frame is easy to melt and causing several cars burst into flames. Then, Ferrari has replaced the glued portion of the heat shield with metal rivets.
