Which of the four types of elastomeric materials has the best dimensional stability?

Question

Quizplus · Accepted Answer

Polysiloxane has the best dimensional stability.There is no taste or odor to the material.
Polysulfide has been around for many years.It has a strong odor and stains clothing.
Polyether material provides better mechanical properties than polysulfide and less dimensional change than silicone,but it is stiff.
Condensation silicone material is odor-free,nonstaining,and relatively easy to mix.The deformation is less than that of polysulfide,but the dimensional stability is superior.
