About CoexFlex™ Filaments

About TPE/TPU Filaments

TPE or Thermoplastic Polyester Elastomer is a combination of a thermoplastic with rubber. Material hardness is measured on a Shore Durometer scale from 0-100 with 100 being the most firm. TPU is part of the TPE “family” but the elasticity comes from a urethane-based ingredient giving it a different type of elasticity than a standard TPE product.

CoexFlex™ 3D Filament Products

Coex offers our TPE products in Natural, Black and White. Our selection of TPE and TPU filaments in the CoexFlex product line will give you a choice from a wide range of flexibility and hardness ratings. Whether it’s purchasing direct from our online store or through a quote for a larger spool or quantity order, we have a CoexFlex product that will meet your needs.

Why should I use CoexFlex™?

CoexFlex products offer you a variety of hardness ratings to give you the exact filament for projects that require flexibility but also resistance to shock and abrasion. CoexFlex filaments allow you to produce items that will be outrageously strong but still give flexibility to the finished product. Get creative and you’ll find many uses for the CoexFlex line of filaments!
