Foam in Pharmaceutical

In the human body, cellular organisms in our lungs play a unique and critical

role in the transport and exchange of gas. The plethora amount of surface area

simply makes the diffusion and transfer of gas very efficient. When polylactic

acid (PLA) was developed in the cellular

structure, its significant amount of internal

surface area and potentially possible

dissolution in blood and open cell structure

generated a lot of applicable interest in the

medical and pharmaceutical segments.

Traditionally, it has been a challenge to build a

temporary scaffold after a major surgery to

allow fast tissue growth and speed up the rehab

and recovery process. Open celled PLA foam

seemed to have the potential as a good

candidate for this area of growth. This

recognition drew a serious amount of interest in

its area of research. Although there is a long

perceived process to make it application

acceptable, the starch based PLA may mean a

lot to the pharmaceutical and medical fields. In

addition, it can easily open the door for bio-

based or plant-based materials and enhance

pharmaceutical and medicinal efficiency or the

natural extension of Chinese and India

traditional medicine. When foam or cellular

technology is applied, the microfiber in the

plant can become easier to be compatible with

our digestive system. Nonetheless, it seems

appropriate to review some interesting research

works for foam in drug delivery and medical

usage.

In scaffold for tissue engineering, the inherent numerous amount of the surface

area is ideal for organisms to grow and to multiply. Tiny soluble powders can

be fused together into an open cell structure to allow tissue to grow; through

which the scaffold may be suppressed enough to dissolve in the blood and

eventually flush away. Fig. 1 illustrates the cell morphology of thermoplastic

polyurethane and polylactic acid (TPU/PLA) in tissue engineering scaffold by

microcellular injection molding. It is noted that not only is there microcellular

cell morphology occurring but the cell wall in an almost nanocellular structure

is present and may be dependent on the weight ratio of the incompatible TPU

and PLA. University of Wisconsin is spearheading this area. Precise control of

polymer chemistry for dissolution, and cell morphology to match tissue

bioactivity, will involve more disciplines to advance the front. In other words,

foam could be a vital part in this multi-disciplinary project. Virtually, this

subject is becoming increasingly important among the global foam community.

More attention from the editorial office will warrant further review works down

the road.

In oral drug delivery, extrusion process has been used to allow one or more

active drug ingredients to disperse in a polymer carrier. After the extruded

drug-polymer air is cooled down into its final form, it becomes what we

normally obtain from the pharmaceutical store. There are at least two

fundamental concerns in this application. One is the poor water solubility, and

PEG disk. b) is an enlarged version in a)

foamed (red dot) and unfoamed (blue triangle)

the other is the pH specific release system for drug delivery in the digestive

organs. Both can clearly reduce the oral drug delivery efficiency. It is clear

that cellular structure can certainly enhance the release rate of the

pharmaceutical chemicals to improve its efficiency. For the PVCap-PVAc-

PEG (caprolactam-copolyvinyl acetate-copolyethylene glycol), it is a novel

amorphous polymer specially designed for solid solutions to increase solubility

and bioactivity of poorly soluble drugs. (Fig.2 shows the SEM of the foamed

PVCap-PVAc-PEG, and Fig. 3 its dissolution curves.) The foamed disc can be

fully dissolved at 50% of the time of an un-foamed disc. In addition, the

reduced density can help floating oral drug maintain its buoyance in acid

aqueous solution. Increase of residence time for effective release can thus be

imagined. Another benefit in foaming is the presence of blowing agents which

can plasticize the drug-polymer system to a point where lower processing

profile is possible to avoid degradation for thermal-sensitive drug ingredients.

In brief, cellular structure appears to be a good methodology in process and

product control of drug manufacturing. It can enlarge the processing latitude

depending on the added kind and amount of blowing agent, which in turn

produces cellular morphology for the effect of drug chemical release. Detailed

efforts are certainly necessary to various drug-polymer systems to conserve

drug ingredients and polymers, and also reduce the cost burden on customers.

Polymer Processing Institute (PPI) is a leading research and development group

in this area.

The implication is clear that foam could be a widely consumed product to make

our living more comfortable and foam can also be applied in specific areas to

fully utilize its features and enhance other critical function. It could be sold in

the packaging segment where we have an array of choices. Yet, it can also be

useful in enhancing medical and pharmaceutical efficiency, which seems to

have limited or no choice at all. Nonetheless, foam is upgraded from a living

improver to life enhancer.

ASIA THE DRIVING FOR BEHIND GROWTH IN ETHYLENE VINYL

ACETATE

Author(s) N/A

Sources Bulk Solids Handling

Corporate/Assignee N/A

Publication Date January 7, 2013

Abstract:

The new report says the impressive manufacturing industry in Asia will be largely

responsible for a predicted worldwide ethylene vinyl acetate demand increase – from

2011’s total of 2,286,193 tons to 2,966,078 tons in 2017, climbing at a Compound

Annual Growth Rate (CAGR) of 4.4%.

According to GBI Research, Asia was accountable for 49% of the global EVA demand in

2011, with the market driven primarily by China (with a 62% share of the continent’s

total), followed by Japan (16%) and South Korea (8%).

Solar Industry Drives Demand for Vinyl Acetate

Although extensively used in the foams and films manufacturing industry, EVA can also

be used in the construction of solar voltaic panels as an encapsulating material. The

growing solar power industry is therefore predicted to play an important role in the future

production of the co-polymer, particularly in China – a major producer of solar power

equipment.

Sources Polymer 53, No.19, 2012, p.4231-4240


Publication Date August 2012

Abstract:

A self-healing microvascular polymeric foam has been developed to improve the

resilience of rigid foam core materials for sandwich structures. We investigated the

healing of brittle polyisocyanurate (PIR) foam after mode-I crack separation in a 3-point

single edge notch bend (SENB) specimen. A two-part healing chemistry based on a

commercially available polyurethane (PUR) foam formulation is employed to rebond the

interface. Both components are initially sequestered in separate channels in a

vascularized SENB geometry. Upon loading and subsequent crack propagation through

the network, the healing agents are released and polymerize on contact to create new

foam material in the crack plane. An attractive feature of this system is the volumetric

expansion of the healing chemistry, demonstrating the ability to repair macro-scale

damage. The foaming reaction occurs on the order of minutes at room temperature,

enabling rapid in-situ healing. Furthermore, by using a vascular delivery technique,

multiple damage–recovery cycles are achieved at consistently high healing efficiencies.

Through repeated mechanical testing, we have demonstrated over 100% recovery in

fracture toughness for this new class of bioinspired, self-healing cellular materials.

Abstract:

Reactive flexible polyurethane (PU) foams were synthesized with two contents of hard

segments (HS) and filled with multi-walled carbon nanotubes (MWCNTs), functionalized

MWCNTs (f-MWCNTs) and functionalized graphene sheets (FGS). The effect of the HS

content and the carbon nanofillers on the kinetics of polymerization and the kinetics of

phase-separation have been studied by Fourier transform infrared spectroscopy (FT-IR)

and synchrotron small-angle X-ray scattering (SAXS). A slow down on the rate of

polymerization and on the development of the polymer structure due to the increase of

the HS content and the inclusion of the nanoparticles was observed. Therefore, this work

demonstrates that there is a relationship between the kinetics of polymerization and the

kinetics of phase separation in flexible PU nanocomposite foams. SAXS data was used to

generate 3D microstructures of PU nanocomposite foams and the phase-separated

morphology was observed by atomic force microscopy (AFM).

Author(s) Kohlhoff*, D., Nabil, A., Ohshima, M.

Sources Polymers for Advanced Technologies 23, No.10, p.1350-1356


Publication Date October 2012

Abstract:

In situ preparation of a cross-linked poly(methyl methacrylate) (PMMA) and polystyrene

(PS) blend and its foaming were investigated for creating a bimodal cellular structure in

the foam. Methyl methacrylate (MMA) monomer was dissolved in PS under supercritical

CO2 at a temperature of 60 °C and a pressure of 8 MPa, and the polymerization of MMA

was conducted at 100 °C and 8 MPa CO2, with a cross-linking agent in PS. The blend was

successively foamed by depressurizing the CO2. CO2 played the roles of plasticizing the

PS and enhancing the monomer dispersion in PS during the sorption process and as a

physical blowing agent in the foaming process. The cross-linking agent was used for

controlling the elasticity of polymerized PMMA domains and differentiating their

elasticity from that of the PS matrix. The difference in elasticity delayed the bubble

nucleation in the PMMA domains from that in the PS and made the cell size bimodal

distribution, in which the smaller cells ranging from 10 to 30 µm in diameter were

located in the wall of large cells of 200–400 µm in diameter. The effects of the initial

MMA content, the concentration of cross-linking agent, and the depressurization rate on

the bimodal cell structure and bulk foam density was investigated.
