One caveat: Typical TPE shrinkage is around 2% while that of substrate materials is closer to 1%. When looking to incorporate sustainable content into your TPE, the raw material cost may be more expensive than traditional materials for three reasons 1) supply chain maturity, 2) high demand, low supply, 3) location of source and supplier. They also require precise venting and vacuum to release off-gassing during the chemical curing process and must withstand temperatures more than twice that of TPE molds (170°F vs. 320-420°F)

Generally, a setting of 375°F (1900°C) at 40 pounds of pressure for 8-10 seconds is enough to change the surface area.
