      Enables reductions in the diameter of a sprue runner


Low birefringence of TOPAS® 5013LS-01

  Comparison of birefringence between optical lenses
Comparison of birefringence by use of imaging lens (ø3.5)
In comparison with a ø5 runner made of a cyclic olefin resin of another company,
TOPAS® 5013LS-01 of even a ø2 small-diameter runner exerts extremely Low birefringence.


Molding processability (flowability: Comparison between competing materials) of TOPAS® 5013LS-01

 

TOPAS® 5013LS-01 is superior to competing materials in thin-wall flowability.
TOPAS® 5013LS-01 is superior in flowability even at low mold temperatures.
