TOPFINE® R1000< fine plastic material for engineering>

Material characteristics

TOPFINE R1000 is a special board material developed by Toyo plastics Seiko Corporation and resin manufacturer Dongli Corporation, which has dimensional stability and good precision hole processing. In the past, super engineering plastics in the implementation of 10 micron diameter hole, will occur after processing, burr, defective products and other issues, so as the precision micro hole machining material, had to use a portion of material such as whole aromatic polyester resin sheet.
TOPFINE R1000 uses a special resin formula and unique molding technology, the greatest possible to reduce the super engineering plastics processing easy burr problem.
TOPFINE R1000 is based on the excellent dimensional stability of PPS, efficient mixing of a variety of special inorganic particles, it can be said that composite super engineering plastics. Because of this, not only machinability, hole processing improved, and has the cutting process difficult fiber reinforced resin outside of ultra-high rigidity.

Material characteristics

Because of the low water absorption coefficient and low coefficient of linear expansion, the dimensional stability is excellent.
The machinability is good, and burr is seldom occurred in micro machining.
