If you are looking for free, high quality experimental data for various polymers, then you might be interested in learning that you can download and use the experimental data from the following links:
ABR

Chloroprene Rubber (7 vol% carbon black)

Chloroprene Rubber (25 vol% carbon black)

Nitrile rubber

PTFE

Silicone rubber

Viton

Also note that I provide experimental testing services for all kinds of polymers through Veryst Engineering. Send me a private message if you are interested in having your material tested and a suitable material model calibrated.

History
The PolymerFEM web site was created by Dr. Jorgen Bergstrom in March 2002.

Background
This site is an independent forum for discussing constitutive models for polymers and their implementation in general purpose finite element programs. What you will find here are general information about material behavior, useful constitutive models, and numerical implementations. The goal of this site is to become a useful reference for constitutive models for polymers. Researchers and users are encouraged to submit results and to request information.
