Adhesive Bonding – Techniques and Considerations

Adhesive Bonding – Techniques and Considerations

A technical synopsis of different methods of adhesive joining

Adhesives are considered as one of the most reliable options for joining two substrates together. Unlike other methods of bonding, adhesives keep the geometry and properties of the materials intact. The technique has considerably matured over the years and every industry relies on adhesive bonding to produce high quality products.

Techniques

Most substrates like metals and polymers are not wettable by adhesives and require some pre-adhesion treatment. There are a number of surface preparation techniques for making materials suitable for adhesions. Some of the commercially used techniques are: Read more

Adhesion and plastic surface treatment

The Adhesion problem is common in materials that possess low surface energies. Examples can include High-Density Polyethylene, Polypropylene, EPDM, and Polyethylene etc. With the surface energy ranging anywhere from twenty nine to thirty six Dyne/cm or mN/m (milinewton per meter). Surface treatment of plastic products

Bottles plastic
Recycling and reuse of plastic bottles are very important for the future of the environment

Obtaining a level of adhesion on any materials with low surface energy i.e. Polypropylene or Polyethylene etc. can sometimes become extremely difficult because of their slickness. Thus, this adhesion problem leads to the printed ink rubbing off, coatings or paint not sticking on the surface along with failed gluing and weak sealing.

Sometimes it is important to treat various different plastic surfaces. Therefore you should always look for the best solution.

In our opinion, there is a need to look for something that:

  • Is green (Greentech/green technology)
  • Presents ROI (Return on Investment)
  • Can be customized

The popular Red cups are also surface treated

The popular Red cups are also surface treated

In parties and rites of passage into “adulthood, by” we drink beer, wine and liquor. We normally use the red cups. A good thing about them is that they regulate the drinking and have a convenient gauge for alcohol pourage. We need not stress ourselves up since the red cups have lines that are a measurement of the rate of drinking. These plastic party cups’ lines are three with reasons;

  1. Bottom line-Is a line for liquor.
  2. Second line-Is a line for wine.
  3. Top line-Is a line for beer.

The Uses of Silicone in the Medical Industry

The Uses of Silicone in the Medical Industry

What Are Silicones?

These are polymers that consist of any inert and synthetic compounds made up of repetitive units of siloxane. Siloxane is a functional group consisting of two silicone atoms and an oxygen atom most frequently combined with hydrogen and/or carbon.

Why are Silicones used in the Healthcare System?

ipadA fairly large amount of history is attributed to the use of silicones in the medical industry. This is so because these substances are highly biocompatible and have increased resilience to various environmental as well as bodily factors. Silicones also display resistance to conventional sterilization methods because of being almost completely inert. All these properties make silicones a popular choice for the manufacturing of a range of reusable as well as disposable medical devices. Read more

Why Metals Are Used in the Automobile Industry

Metal: Silver and gold may seem to have taken the throne but when it comes to building a strong automobile industry, it is base metals that take the lead. These have proven to be the key to success in terms of constructing durable structures and lasting vehicles. Read on to find out why metal is becoming increasingly popular in the automobile industry.

The Increased Usage of Plastics in the Medical Industry

The Increased Usage of Plastics in the Medical Industry

From the earliest times of Mesoamericans to the modern times, the use of plastic has been employed to carry out the construction of various items all over the world. It has evolved tremendously to suit the requirements of the ever increasing demands of the human race. The use of plastic is extensively based on its durability and reliability amongst other qualities. Of all the construction materials available, plastic is the only substance which is used in a variety of forms.

Polymers have been of pivotal importance to humankind ever since 1600 B.C. With the invention of vulcanized rubber in the year 1839 and the discovery of polystyrene (PS) by an apothecary of German origin in the same year, there has been no looking back at the widespread utility of plastics around the world. Before commencing onto the advantages of using plastics in the world of Science and Medicine, you should know about the various kinds of plastic being utilized in this field Read more
