Avient Corporation 6
• A number of different shapes and
designs are created and simulated to
determine which one works best
• Refining to meet EN standard
• VDT TPEs can help reach compliance
with EN1621-1 level 2 and EN1621-2
level 1
• Optimum protection can be achieved
by combining industrial design and
engineering

PolyOne also will present an update to the unique 3D-MID (three dimensional molded interconnect device) manufacturing technology it highlighted at its stand during Fakuma 2014.
By collaborating, PolyOne and selected developers have succeeded in establishing a time- and cost-saving means to produce the 3D-MIDs serving as heat sinks in LED lighting, which could prove an alternative to the complex printed circuit boards now fairly ubiquitous in these applications.
https://www.avient.com/technical-tips-transfer-printing
When printing transfer graphics that have disciplined registration, it is important that all moisture is removed from the paper before the print run commences.
Plastisol heat transfers are mostly printed on specially prepared transfer papers.
Finished/printed transfers should be kept in an environment that is not hot or cold.
