SIGMASOFT Thermoplastic: Unfilled Amorphous Material

Test ID



This TestPak generates the properties needed to perform a simulation of the filling, packing, and cooling phases, as well as warpage/shrinkage and viscoelastic post-molding behavior. These include Bagley-corrected viscosity vs. shear rate at three temperatures (two in the processing range and one below); thermal conductivity; specific heat vs. temperature; PVT data taken in the isothermal heating mode for amorphous materials; and stress vs. strain at five temperatures, along with modulus, Poisson’s ratio, and CLTE. Model fitting for SIGMASOFT is included.

Included Tests

1x M-101T SIGMASOFT Mechanical Test
1x D-020 PVT (Isothermal Heating)
3x R-012 Capillary Rheology with Bagley Correction (1 Temperature)
1x T-303 Thermal Expansion Coefficient by TMA
1x T-015 Specific Heat
1x T-103 Thermal Conductivity Scan


For semi-crystalline material please see TestPaks G-264 and G-266

This TestPak is intended for only unfilled amorphous materials. The TestPak generates properties used to simulate everything from filling and packing phases to shrinkage/warpage and viscoelastic behavior.
