because the liquid coating is held in
place between the textures. The coatings
can be custom designed to adhere to a
variety of surface materials, and can be
designed to be edible or to withstand
harsh industrial environments. " The ingredients
in LiquiGlide's coatings are
FDA approved pharmaceutical grade
materials, " said Rippy. Colgate has become
one of the first to apply the technology
in a consumer product. The company's
Elixir toothpaste, which comes in
different colours, including black, is now
sold in Europe. Further details on the
roll-out of the product will be announced
in due course.

toothpaste tube with
LiquiGlide technology
Colgate has launched a new product that
promises to solve the frustration of messy
toothpaste tubes. Transparent, so that the
contents are visible, this recyclable PET
packaging makes sure every last bit of
toothpaste is squeezed from the tube - no
squeezer required.
Product residues stuck in the packaging
are a huge source of waste that often goes
unrecognised. More than 50 billion packages
are sold every year containing viscous
products, leaving enough of the contents
behind in these packages to fill up 110,000
semi-trucks. This is not only a waste of product
- contaminated packaging cannot be recycled
and will either require extra washing
steps - which costs extra energy - or it will
end up being landfilled or incinerated.
A US-based start-up called LiquiGlide
is now commercialising technology to address
this problem. Founded by MIT researchers
Kripa Varanasi and Dave Smith,
LiquiGlide was spun out of MIT in 2012.
The technology is based on the idea
of eliminating friction, enabling thick,
slow-moving liquids to flow easily, resulting
in virtually every last drop of the product
exiting the package. This is achieved quite
simply through the use of coating layers.
As Executive Vice President and General
Manager of LiquiGlide's Biomedical Division,
Dan Rippy, explained, it's a question
of mechanics. Surfaces vary widely by type,
he said, but key to LiquiGlide's coatings is a
bi-layered approach that creates one layer
that becomes solid and textured with microscopic
ridges and gaps, and a second liquid
layer that fills up these gaps, said Rippy. A
durable slippery coating is created through
the application of the liquid layer to which
the contents of the packaging will not stick.
In other words, LiquiGlide fundamentally
changes how liquids and solids interact.
The surface continues to be slippery

New honeycomb cores
support recyclability
EconCore, a global leader in honeycomb
technologies, has developed new honeycomb
cores for laminated sandwich panels
made with SABIC's NORYL GTX resin,
a polyphenylene ether (PPE) blend, and
EconCore's proprietary technology.
Thermoplastic honeycomb structures
deliver a high performance-to-weight ratio
and efficient energy absorption under
impact. Combined with an effective, inline
integrated sandwich panel production
technology, this weight reduction
has positive implications for overall production
cost savings and environmental
responsibility. In addition to reducing
raw material use, the honeycombs support
recyclability.
The new honeycomb structures deliver
higher heat performance, greater dimensional
stability, and lower water absorption
than alternative materials. They
New OPC UA specifications released
The Joint Working Group consisting of
EUROMAP and the OPC Foundation has
released two new parts of the OPC 40082
specification 'OPC UA Interfaces for Plastics
and Rubber Machinery - Peripheral
Devices', developed by two sub-working
groups to standardise the data exchange
with hot runner equipment and liquid silicone
rubber (LSR) dosing systems.
The two specifications define which
data are to be exchanged via the open
machine-to-machine communication
technology OPC UA. This includes information
for central monitoring of the
device and process status, but also
functionalities so that the connected
injection moulding machine can directly
influence process parameters. This
considerably simplifies the integration
of machines and devices from different
manufacturers in a production cell and
embedding them in a higher-level system.
In addition to the one-off efficiency
gains, networking also enables targeted
control and monitoring of production
during operation. The published OPC
UA specifications for plastics and rubber
machines can be downloaded from the
websites of the OPC Foundation, EUROMAP
and VDMA.

also exhibit high load-bearing capacity
up to 180°C.
EconCore's technology also offers expanded
freedom to design and produce a
wide range of honeycomb cell sizes, core
thicknesses and densities. The company
has licensed its integrated technology
for production of lightweight honeycomb
panels in specific configurations for applications
in the industrial packaging,
automotive, transportation and construction
industries.
