Polymers and Their Additives – Their Applications in Industry

Polymers and their application in the industry have been very widespread for many decades now. Plastic polymers have small molecules with chemical properties that make them ideal for use in manufacturing many household and industrial things. Some of the many factors that make polymers so popular include thermal conditions, stress withstanding capabilities and resistance against other chemicals.

But polymers by themselves are prone to damage too. Some changes, such as unintentional reduction in molecular weight, can lead to plastic degradation and product failure; manufacturers need supplement to improve a polymer’s characteristics and these supplements are commonly known as Polymers Additives.

Polymers such as rubber are naturally flexible. It is a desirable quality but it is not universally present. Lignin and cellulose nitrate are some comparatively rigid and softening them to exhibit rubber like properties is difficult unless it is plasticized. For this reason, plasticizing compounds may be added to a polymer to reduce its stiffness and increase its formability. Polymers Additives help in achieving this.

Also polymers aren’t colourful. Manufacturers impart colour to them with the help of Polymers Additives. The process is called pigmentation. Pigmenting additives can be used to change colour of plastics, which makes a whole range of consumer products highly desirable. However, some colouring agents increase a polymer’s susceptibility to chemical reactions. Manufacturers need to make careful selection in order to avoid degrading plastics in the name of adding colour to them. Polymers Additives are very necessary in the plastics industry and in order to know more about these get in touch with an additive maker.


Masterbatches for agricultural applications (Part I)

For long, Agriculture was the backbone of our economy – it still holds enormous value. In fact, agriculture, along with fisheries and forestry, is one of the largest contributors to the GDP (Gross Domestic Product) of our country.

Over the past 65 years since our independence, this sector has completely transformed (though it still heavily depends on rain water for its irrigation needs).

Herein this blog post, we’ll talk about an important element that’s been playing a greater role in the growth of the agriculture sector – and that element / product is ‘masterbatches’.

Wikipedia defines masterbatches as, ‘a concentrated mixture of pigments and/or additives encapsulated during a heat process into a carrier resin which is then cooled and cut into a granular shape. Masterbatch allows the processor to colour raw polymer economically during the plastics manufacturing process.’

In agriculture, masterbatches are used in the manufacturing of –

Mulch film
Green house films
Drip irrigation systems
Shade nets

The leading masterbatch manufacturers and suppliers of the country are investing enormous efforts and funds into their research & development to continue to innovate and improve upon their range of masterbatches. So in the years to come, we can see the product range getting wider and better and more products being made of these masterbatches.

Now we’re going to write down a couple of posts on the role of masterbatches in the agriculture sector. So please regularly check this space. If you want to read more about masterbatches, then please read our already published posts on this blog. We’d also like you to share your opinions / ideas about masterbatches and the challenges you face when you look out for a supplier. If you’ve a question or a query, please drop us a comment. We’d love to answer!
