For
any product to reach its final stage, it has to go through the whole process of
being extracted from raw materials, further refining or combing with other
materials, and then further processing. Adhesives, are an essential component
in the manufacturing of numerous products, be it any industry, such as
electronics, wood/timber, packaging, leather goods, or furnishing. This is
where acetyls come in; they are an essential component of adhesives themselves.
Acetyls, such as vinyl acetate and ethyl acetate monomer, are significant in
the adhesives industry. Ethyl acetate solvent-based adhesives have a better
bonding strength than equivalent toluene-based adhesives. Poly vinyl acetate (PVA or PVAc), commonly known as wood glue or
carpenter’s glue, extensively utilizes vinyl acetate monomer for its manufacturing.
When it is emulsified in water, it is used as an adhesive for porous materials,
such as cloth, wood, paper, and sandstone. Therefore, acetyls are in high
demand due to the flourishing end-use industries where adhesives are used.
In
a P&S Intelligence study, it was reported that the acetyls market would
accumulate $34,283.2 million in the coming years, advancing at a 6.9% CAGR from
2015, when it garnered $22,004.7 million. An acetyl group contains a methyl and
a carbonyl group. From a small molecule, such as an OH group,
to those with long chains of carbon atoms, this group can be attached to any
molecule. The acetyl group is used in
the manufacturing of various products, such as acetic anhydride, acetic acid,
ethyl acetate, and vinyl acetate monomer.

In 2015, among all the products derived from those with an acetyl group, acetic acid was consumed the most. Acetic acid, also known as methanecarboxylic acid and ethanoic acid, is a colorless liquid with a pungent smell, which is used as a raw material in many industries. Even in the coming time, acetic acid would continue to be in the highest demand.
Among
North America, Asia-Pacific, Europe, and other parts of the world, the highest
demand for acetyl and its derivatives was generated in the Asia-Pacific region.
This can be attributed to the various flourishing end-use industries, such as
packaging and textiles and paints and coatings and the growing requirement for
adhesives in construction and furniture here.
The improving gross domestic
product of many countries, such as India and China, has resulted in the
increasing spending power of customers as well as money inflow in industries,
thereby resulting in a high demand for finished products. This region is
expected to generate the highest demand for acetyls in the coming years as well
as the requirement for products manufactured by numerous industries would be
the maximum here.
A
shift toward renewable energy from non-renewable sources is being observed as
the latter are leading to high levels of pollution. Photo voltaic (PV) modules
are used for storing energy generated from the sun. These modules have a glass-top
surface, an outer frame, a rear layer, and an encapsulant, which is mostly made
of ethylene-vinyl acetate (EVA).
In the solar power industry, EVA is gaining
popularity due to its superior optical properties, cross-linking bonding
abilities, and high durability. One of the major challenges that solar module
manufacturers face is ensuring that in harsh outdoor environments, PV modules
last long. EVA, a copolymer of vinyl acetate and ethylene, is used to make the
encapsulant, which provides better protection against delamination and
corrosion and has remarkable durability.
