Projected Decrease in Global Transportation Emissions Aided by Use of Adhesives vs. Mechanical Fasteners

Posted By ASC, Monday, December 5, 2016

The International Council on Clean Transportation recently published a graph showing the projected convergence of emissions regulations globally by 2025. Much of the projected decrease in emissions will result from fuel economies realized through lightweighting, and that’s where adhesives have a vital role to play as auto makers ditch the weight of mechanical fasteners and turn to alternative materials and the adhesives needed to effectively bond the new materials.

 

The trend lines are clear, and by 2025, there will only be 10 to 15 percent variance between emissions regulations globally. This harmonization will provide common performance targets across regions. According to an analysis by Henkel Adhesives, it is predicted that the convergence will lead to the use of common designs that will improve manufacturing flexibility and reduce costs. OEMs will be designing and building vehicle platforms and components to serve a market where common lightweighting goals to reach emissions targets will be shared, and where vehicle lightweighting programs will excite global interest.

Bostik Launches First Olefin Elastic Attachment Adhesive

Posted By ASC, Monday, November 28, 2016

Bostik, a member of the Arkema group of companies, has announced the launch of a new olefin elastic attachment adhesive. The product is the first high-stress hot melt polyolefin adhesive that can be used to attach elastic strands to items such as disposable diapers and adult incontinence products. Previously, polyolefin adhesives were only suitable for low-stress applications. It will be marketed under the trademarked name “Brilliance™”.

 

The company says its adhesive will perform reliably across substrates and different types of elastics, and is compatible with a variety of application equipment types and line speeds. This allows manufacturers to make production line alterations and improvements without having to be concerned about adhesive performance being affected. The adhesive offers opportunities for improved fit and leakage protection while offering a higher bond strength, low odor and reduced bleedthrough.

 

Brilliance™ was developed in partnership with disposable hygiene product manufacturers, and was tested in Bostik’s US, French and Asian facilities.

CDC Study Trumpets the Benefits of Dental Sealants

Posted By ASC, Monday, November 21, 2016

The Centers for Disease Control and Prevention (CDC) has studied dental sealants that are applied to teeth to prevent decay, and found that over a two-year period, the sealants prevented 80% of cavities. Over a four-year period, children whose teeth had been treated with dental sealants had 50% less cavities.

 

Some parents are concerned about exposure to bisphenol A (BPA) through dental sealants, but although traces of BPA can be found in saliva during the first 24 hours after application, no BPA was found in saliva thereafter. In addition, blood tests did not indicate the presence of BPA in the bloodstream after dental sealant application. Dentists say they have never treated any patients who had an adverse reaction to the sealant.

 

CDC personnel point out that procedures used to treat decaying teeth will expose children to far more chemical agents than sealants, and conclude that dental sealant risks are negligible and that benefits far outweigh any perceived risks.

Children’s teeth should be treated with sealants as soon as fissured teeth (molars and premolars) begin to appear. However, adults are also able to benefit from dental sealant technology, provided their teeth have not previously been filled.

Adhesives.org Article: Adhesives Boost Loudspeaker Production Efficiency

Posted By ASC, Tuesday, November 15, 2016

The demand for loudspeakers is growing. Whereas the average car used to have four loudspeakers and two tweeters, modern cars can have as many as 20 speakers. To make loudspeakers, at least seven bonds are required per speaker, and the adhesive has to be flexible to enhance sound through vibration damping. In addition, the bonds must resist impact, exclude humidity, and tolerate temperature variations.

 

Although cyanoacrylates are still widely used, the bond between the spider and voice coil can be achieved more efficiently when a UV or light curing adhesive is chosen. Not only is it possible to achieve bonding in 10 seconds or less, but these adhesives will tolerate the high temperatures that come from energizing the voice coil.

 

Efficiencies are also realized when light curing adhesives are used to bond the “spider” to the “basket” and the membrane to the voice coil. Many manufacturers could benefit if they integrate light-curing adhesives into production lines to reduce the volume of work in progress by speeding curing time. It is possible to obtain the 20 newtons per centimeter peel resistance that…

Toray Plastics Launches New Polypropylene Films and Sealant for High Altitude Packaging

Posted By ASC, Monday, November 14, 2016

When goods are transported at high altitudes, the lower air pressure in aircraft holds causes the packaging to inflate. The increased pressure on the package seal may cause it to pop, a problem that has confronted food packaging companies until recently. Now Toray Plastics (America) has launched a range of biaxially oriented polypropylene (BOPP) films which, when combined with a proprietary sealant, eliminate or significantly reduce high-altitude package popping.

 

The new range of films, dubbed Over-the-Mountain (OTM) films, are intended for use in food packaging pillows, pouches and stand up pouches. Channel leaks in challenging seal areas are eliminated by using a high-performance sealant that also prevents oils from leaking out of packaging leaving behind greasy residues.

 

Apart from solving package seal problems, the robust new films allow for 2-ply lamination, helping companies to speed the packaging process while saving costs. Existing BOPP film production line equipment need not be adapted to accommodate the new film.
