Product Description



Melt Flow Index Testers and Accessories

BT Technology Inc. has two melt flow index models available as well as a
variety of options to support them.

AD-S-BA-000 Melt Indexer (Method A)
AD-S-BA-500 Melt Indexer (Method A & B)

Both devices meet ASTM D1238 and D 3364

In our experience Method A is the most accepted procedure for most polymers
used in geosynthetics.
