Global Foam Markets Trend

Foam Update presented consumption data of Chinese foam market in the

editorial of Oct. 2010, which was widely used by some credible publications.

Fig. 1 is an excerpt from CRC Press in its forthcoming Foam Extrusion 2nd Ed.

It shows that Chinese foam market has consumed 20% more than US market

has done in 2009, and PS foam occupied slightly over 60% of the overall foam

usage in China. As the global economy has been stabilized, and began to show

recovery in 2013, quite a few positive market reports came out, most with

encouraging growth predictions. In the News of this Foam Update, Plastemart

suggests an average 11.4% annual growth for the global polypropylene foam

market from 2013 to 2018. Most growth comes from increased consumption in

packaging, construction, and automotive. Research and Markets group

forecasted the global polyurethane market will grow at an average growth of

7% per year till 2018, in which increasing demand for bedding and furniture,

and construction was cited. The global demand for mattresses will be reached

approximately US$33 billion in 2018. These industries are not like the core

food industry which is relatively independent of economy condition; rather they

are a good indicator of economic strength. Therefore, the good news is

consumption will continue to be strong around the world in the new few years.

The challenge is how to capture the momentum and make the most out of it.

Foam Update

March 2014


According to Bayer Material Science, Asia-Pacific was the largest PU foam

region in 2012 which occupied about 44% of the global PU market, whereas

North America had 18%. The consumption dynamics seem to shift quite a bit

within the last few years. There is no question that China is the number one

consumption in the world. For almost every emerging market, momentum is an

early key parameter than direction. Adjustment becomes necessary to make

balanced growth and development. In 2014, China recognized this and is trying

to adjust its development pace. As a result, growth may not be as bright, yet its

overall benefits will be more sustainable. When strategy for growth is being

shaped, foam technology plays a vital role in both developed and developing

regions. Flame retardancy and insulation continue to be the key requirements

for foam in construction. Recycle and reuse offers economic incentive, which

needs no more emphasis. Incineration causes smoke, ashes, and decomposed

components into the open atmosphere. Degradable foam without generating

environmental impact is another priority subject for research and development.

It makes sense to strain forward and to connect. Since China is being

transformed from manufacturing powerhouse to technology development

center. Foam update is willing to host a Foam Conference in Shanghai, Dec.3

and 4, 2014. Considering foam Conference in Europe by Rapra and AMI, North

America by SPE for over a decade, it is proper to start one in China to allow

global experts in foam business, technology, research and development to be in

one room for enlightening and encouraging one another for more collaboration

and breakthroughs. Registration form is attached. For Foam Update subscriber,

recommended for further communication and networking. More updated

Publication Date January 30, 2014

Abstract:

Polymer foams are used in various consumer products that provide durability, comfort,

support, and safety. These polymer foams are lightweight and less costly compared to

other substitutes such as metallic foams or fiberglass. Their growing demand reflects

their versatile nature against other competitive materials. Polymer foams are generally

foamed plastics of polymer resins. Flexible polyurethane foam is one of the most

versatile materials as it is used in furniture, bedding, carpet cushion, automotive, and

packaging applications. There are seven major types of polymer foams available

commercially: Polyurethane (PU), Polystyrene (EPS & XPS), Polyolefin (PE & PP),

Polyvinyl Chloride (PVC), Phenolic, Melamine, and others.

PREPARATION METHODS AND PROPERTIES OF HYDROGEL: A REVIEW

Sources International Journal of Pharmacy and Pharmaceutical Sciences, (2013) vol.

5, Issue 3, pp. 112-117


Publication Date May 30, 2013

Abstract:

Hydrogels are three-dimensional cross-linked polymer network that can respond to the

fluctuations of the environmental stimuli. These biomaterials can incorporate large

quantum of biological fluids and swell. When swelled, they are soft & rubbery and

resemble the living tissue, exhibiting excellent biocompatibility. Today, drug delivery

experience several challenges where hydrogel could be one potential answer to those.

Thanks to the unique properties of hydrogel for which they are widely exposed to

different biomedical fields. Hence the preparation techniques of hydrogel biomaterial and

the evaluation of the properties are of utmost significance. Literature reveals that this

three dimensional architecture could be homo-polymeric, co-polymeric, semi-

interpenetrating and interpenetrating polymer networks (IPN) based on preparation

methods. Polymeric blends like semi-IPN have also been investigated to satisfy the

specific needs of biomedical field. Such blends have shown superior performances over

individual polymers. Unique biocompatibility, flexible methods of synthesis and tailor

able physical properties have made the hydrogels to be used as a drug delivery device to

tissue engineering scaffolds. As scaffolds they should provide structural integrity like

tissue constructs and as a drug carrier it should have sufficient mechanical strength to

control and protect the drug and proteins until they are delivered to the specific sites of

the biological system. Hence, the evaluation of swelling, mechanical and biocompatible

properties consider more attention before the hydrogels are applied. In this review article

an attempt has been made to describe the available methods of hydrogel synthesis along

with their inevitable properties.

Publication Date August 21, 2013

Abstract:

An auxetic polyurethane (PU) scaffold was prepared to investigate chondrocyte

proliferation under compressive stimulation for cartilage regeneration. To give a negative

Poisson’s ratio to the PU scaffold, volumetric compression with a 3 : 1 ratio was applied

during heat treatment. For the control PU scaffold, the Poisson’s ratio was 0.9 ± 0.25

with elongation at 20% of the strain range. Poisson’s ratio for experimental specimens

was approximately −0.4 ± 0.12 under the same conditions. In cell proliferation tests, cells

were cultivated within the prepared scaffold under compression with a 20% strain range.

With a 20% strain range elongation, the compressive load was approximately 0.3N. The

experimental group showed a 1.3 times higher cellular proliferation rate than that of the

control group after 3 days in culture. At day 5 of culture, however, the rate of

proliferation of the control group increased so that there was no significant difference

between groups. However, collagen content (produced by the cells) in the cell-

proliferated medium was 1.5 times higher in the experimental group after 5 days in

culture. This may have been due to the effectiveness of the auxetic structure of the

scaffold. An isotropic compressive load was transmitted to the cells due to the negative

Poisson ratio of the scaffold.

Abstract:

In the last three years, global consumption of polyurethane has been growing by approx.

5 % per year. In 2012, it reached a volume of 15.3 million t. This encouraging growth

trend can be expected to continue in both the middle and long term. The global factors

strongly contributing to this include increasing urbanization and mobility, the economic

growth driven by rising living standards, mainly in threshold countries, and last but not

least, worldwide measures for saving energy.

Publication Date February, 2013

Abstract:

The activities of the Foam Technologies R and D group at Fraunhofer ICT have focused

for more than ten years on new materials and processes for foamed thermoplastic

polymers, in both particle foams and direct foam extrusion. Today biopolymer foams

play an important role in research activities. Special emphasis is placed on material

development and foaming behaviour of cellulose-based polymers and the characteristics

of bio-foam parts. The modification of polymer properties depends on the application.

The latest research focus deals with environmentally friendly flame retardants, which is

relevant in building insulation. For this purpose, the interaction between phosphorus-

based and nitrogen-based products, layered silicates and graphite with cellulose-based

polymers are analysed.
