EPDM rubber is commonly used in the automotive industry to make several parts of vehicles including the seals of doors, the trunk, the hood, and the windows. It is also used for other purposes such as temperature controlling because of its insulating properties. Practical uses of EPDM rubber include cold rooms, radiators, garden appliances and electrical insulators, tubes and hoses, washers, solar panels, speakers, and headphones.
EPDM rubber can either be conductive or non-conductive which is why plasma treatment is needed to activate it and to achieve a strong bond between the rubber and the adhesive during the flocking process. It is also needed to wet the rubber in the slip coating stage to obtain the desired properties for adhesion. Plasma treatment is used as a replacement of chemical treatments as chemicals are generally dangerous, low yielding, and high in cost. Read more
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.
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
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
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:
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;
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?
A 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
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.
Characteristics of Metals
Can form alloys
Enables and speeds up various chemical reactions
Adds attributes to plastics such as flame resistance, decreased degradation rate etc
