A new coextruded film provides ultraviolet and other
protection to vertical laminates used on exterior structures.
"The film brings optimal UV protection," says Michael
Golder, worldwide manager of high pressure laminate films for Evonik
Industries. "It absorbs more than 98 percent of the UV rays."
The base layer of the film, designated Europlex® HC 99716 Film, is 45 microns
of pure polymethyl methacrylate, a transparent thermoplastic also known as
acrylic. The top layer is polyvinylidene fluoride (PVDF), a non-reactive and
pure thermoplastic fluoropolymer. The PVDF was added by Evonik to provide an
additional layer of protection. "Anti-graffitti properties come from the very
low surface tension of PVDF," says Golder. "Nothing sticks to it."
One of the key features of the film is its ability to
chemically adhere to melamine, a substrate that gives the laminate structural
strength. Special reactive components were added to the base resin so that it
would adhere to melamine. No adhesives are required.
Use of high-pressure laminates as a building façade has been
rapidly growing in Europe and Asia. Total
worldwide use is estimated at 2 million sq ft. One use is to protect a wooden
surface, or to simulate a wooden surface through use of a melaminic resin-impregnated
decoration paper. Golder says than an effort to market the material in North America will be launched in early 2010.
So far the focus is architectural faces. But Golder says
other applications may be coming. For example, horizontal coverings are
possible if scratch resistance of the panels can be improved. Price of the film
is approximately 34 cents per square foot (€3.50 per square meter).
The 3D printing revolution seems to have a knack for quickly moving technology ahead by way of collaborative effort and even a little friendly competition -- all of course in the name of scientific advancement.
Advantech has launched a new series of motion-control I/O modules to meet the increased demands that come with more distributed industrial systems that require control of a growing number of axes and devices.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
