Polyurethane, commonly known as PU, is possibly
the fastest growing polymer after LLDPE (commodity)
and container grade PET. In fact, about 10 million
tons of PU was consumed globally in 2005 � marginally
lower compared to PET container grade. PU belongs
to thermoplastic group and is the largest thermoset
material and is also available as a thermoplastic
known as TPU (Thermoplastic polyurethane). Consumption
of TPU is significantly small out of the total
PU consumption (not more than a few percent).
Globally PU is expected to grow at almost double
the GDP growth (5-6%). Asia, as expected is
growing much higher compared to the developed
economies of North America , Europe and Japan
. Regional distribution indicates Europe to
be the largest followed by North America and
Asia including Japan. Europe has almost 30%
share while Asia is slowly gaining ground and
has reached a level of about 27% in 2005.
Polyurethane is manufactured from two monomer
: isocyanate and polyol.
TDI is the oldest isocyanate and is the larger
isocyanates used so far. Usage of MDI is smaller,
but has a faster growth rate in the past few
years. MDI is expected to grow faster for another
decade, if not for longer period. The consumption
of isocyanate and polyol depends upon the finished
product.
Typically, flexible PU products use maximum
of 15% of isocyanate while the rigid products
use about of 30%. TDI has almost 45% share and
MDI has 25% share. The remaining 15% belongs
to special isocyanates that are used for special
PU used in adhesive and coating. PU products
besides isocyanate and polyol use 10% catalyst,
surfactant, blowing agent, pigment/colourant
and filler.
Among the isocyanates, MDI is expected to grow
at about 8% while TDI is likely to grow at 3-4%.
Typically MDI is used in rigid application while
TDI is used in flexible products. MDI is also
increasingly snatching TDI share even from flexible
product range. In fact it is believed that the
growth of MDI is increased by 1 % while substituting
TDI as raw material.
India has shown a very healthy growth of about
14 % over the last 15 years. From a level of
17 KT in 1990, the consumption has reached a
level of 120 KT in 2005. Exhibit 1 also
describes the application of PU in India in
2005. Flexible products have a significantly
larger share while rigid PU is only less than
5 KT out of which 1.5 KT is TPU.

Higher growth is seen from 1995 to 1998 compared
to earlier phase from 1990 until 1995. It is
almost similar between 1995 and 2005. In fact
it is expected to grow slightly faster in the
next 5 years. The main reasons for higher growth
are:
Indian PU market is concentrated in flexible
products. Exhibit 3 summarizes the end-use application
and clearly shows a preference for flexible products.

Pioneered by U�foam, India began production of
PU flexible slab stock in 1960. However it is
no longer a major force to reckon in this sector.
There are two other larger processors in flexible
products of foam. They are:
Sheela foam, Ghaziabad UP
Tirupati foam, Ahmedabad, Gujarat
Automotive moulded products are
manufactured by:
 |
 |
Bharat Seats |
 |
 |
Krishna Maruti |
 |
 |
Polyflex |
 |
 |
Tata Johnson Controls |
All major refrigerator producers
in India also manufacture PU insulation slab stock.
Footwear producers such as Action and Liberty
footwear are the major producers of PU shoe sole.
Flex group and Paper converter are the major players
in PU adhesive and sealant
For quite sometime, India did not have manufacturing
facilities for PU rfeedstock- TDI, MDI or polyols.
Expanded Incorporation at Mumbai and Manali Petrochemical
Ltd at Manali Chenai manufacture Polyols in India.
Narmada Chematur with 18 KT capacity of TDI has
partially fiiled the void. However, MDI is still
not manufactured in India and is required to be
imported. The dependence on import of several
small sized processors affect cost effective imports
of MDI. It could be one of the reasons for somewhat
slower growth of MDI at least until the end of
2000. In 2000, imports were liberalized and the
import tariff was reduced to a significant extent..
Indian PU market is expected to grow at about
12-13% if not at about 15% in the coming 5 years.
The demand in 2010 is expected to reach a level
of 215 KT from 120 KT in 2005 and thus is expected
to grow at an average growth of 12.5% This estimate
could be conservative. It is possible that 13.5
% growth could be seen and the demand could reach
a level of 225 KT instead of 215 KT.
Indian Polyurethane Association chaired by Mr.
Sarangapani of U foam and the doyen of Indian
PU industry is the chairman. He is operating from
his Hyderabad office. Mr. Ramamurthy is the secretary
and is located at Chenai. Indian Polyurethane
Association brings out quarterly magazine regularly.
It also promotes the newer developments of PU
applications. Recently it conducted a conference
and exhibition at Delhi in October 2005.
