This high-level, objective look at both TPEs and LSR touches on some key topics to consider in three critical categories—design, production and performance—to help you make a more informed decision. Though the viscosity of TPEs are reduced when processed at high shear rates, TPEs must be “packed” into a mold to ensure complete fill-out. Because LSR cures at high temperatures, using it as an overmold material in a two-component molding system requires pairing it with high temperature thermoplastics to overcome the risk of melting or deforming the substrate.

High levels of regrind are better tolerated in black materials. GLS TPEs have high elongation and good tear strength and therefore require the use of a high quality grinder with sharp knives. This will result in high molded-in stresses.

Polyoxymethylene (POM) is often the preferred solution for precision parts that demand high strength and stiffness, a low coefficient of friction (COF), and excellent dimensional stability. However, this semi-crystalline-engineered thermoplastic has toxicity issues due to its residual formaldehyde content, a substance of very high concern (SVHC), according to the European Chemicals Agency (ECHA).
