Some examples of polymers with high shrinkage rates include high-density polyethylene (HDPE), polypropylene (PP), and polycarbonate (PC). These materials have a high degree of crystallinity and can experience significant shrinkage during cooling.

On the other hand, some examples of polymers with low shrinkage rates include acrylonitrile butadiene styrene (ABS), nylon, and thermoplastic elastomers (TPEs). These materials have a lower degree of crystallinity and may experience less shrinkage during cooling.
