Santoprene is an ideal material to consider using for your commercial fabrication project. This type of polymer is commonly known as a thermoplastic elastomer or even thermoplastic rubber. It is an advantageous choice for manufacturing because it has the properties of both thermoplastics and vulcanised rubber. In simple terms, santoprene has good machinability like a thermoplastic, so it can be heated repeatedly for easy fabrication during processing. In addition, the material has elastomeric properties like rubber which means that the final product will be impact-resistance, good waterproofing and extensive durability. If you choose to use santoprene for your business manufacturing project, here are the primary processing options to inquire about from your fabricator.


Plastic extrusion is an ideal processing method for santoprene fabrication project. The popularity of the manufacturing technique can be primarily attributed to the simplicity of forming custom products. Basically, the process involves feeding the raw santoprene material into an extruder barrel. The polymer is melted in this container using heaters that are placed strategically around it. The molten material is forced into a die which forms the plastic into the desired cross-sectional design.

This method is favourable because it can be used to form continuous custom products such as pipes, sheets and rods. Santoprene can also be co-extruded which means that multiple layers of the plastic can be formed simultaneously to create a stronger product. In addition, the straightforward nature of this manufacturing method translates into lower project costs. On the other hand, not all designs can be made by extrusion, so there might be limitations for your custom products.

Injection Moulding

Injection moulding is suitable for manufacture of santoprene custom products because it can handle very complex designs. Generally, the technique will require melting of the thermoplastic in specialised equipment. When the material achieves the desired viscosity and consistency, it will be forced into a mould cavity. In most cases, a ram or even a plunger component is incorporated to make this process more efficient. The mould cavity is usually formed to conform to the shape of the custom design, so the product possibilities for your commercial project are virtually limitless. Once the plastic solidifies, the pertinent commodity will be ready. Moulds can be reused, so this method is ideal for volume production.


Thermoforming can be used to manufacture santoprene products when the raw material is in form of a sheet. Basically, the thermoplastic rubber will be heated to pliable temperatures and formed into a desired shape. The product will be trimmed to improve aesthetics and functionality.
