Choosing Between Polyurethane and Silicone
Match the material to your project, casting method, and production volume.
Silicone rubber is well-suited for originals with fine undercuts or delicate surfaces, offering excellent release without adhesion to most substrates. Polyurethane rubber is a strong choice when mold durability and higher production runs are the priority. Both are available in a range of hardnesses to fit your foundry application.
