描述
Santoprene 201-80 is a soft, natural, colorable thermoplastic vulcanizate (TPV) from Celanese developed for a broad range of injection molding, extrusion, blow molding, thermoforming and vacuum-forming applications.
Celanese describes the grade as a versatile TPV in the thermoplastic elastomer family that combines good physical properties and chemical resistance with conventional thermoplastic processing.
Unlike black-only TPV grades, Santoprene 201-80 is supplied in a natural, colorable form. This makes it especially useful where the final part must be supplied in custom colors, light shades or color-coded versions for product identification, branding or assembly management.
The grade has a current Shore A hardness of approximately 86, placing it in the firmer part of the soft-elastomer range.
Despite this relatively high Shore A hardness, Santoprene 201-80 still offers very high elongation. Current Celanese data lists approximately 540% elongation at break, together with approximately 11.1 MPa stress at break and approximately 4.7 MPa stress at 100% elongation.
This makes the material suitable for applications where the component must hold its shape more firmly than a 60A or 70A TPV but still retain substantial elastic deformation.
Celanese specifically identifies excellent flex-fatigue resistance as a key feature. This is important for parts such as bellows, diaphragms, flexible boots, grommets, tubing and other components that repeatedly bend or flex during use.
The manufacturer also highlights excellent ozone resistance, which supports outdoor and automotive applications where elastomeric materials may be exposed to atmospheric ozone for long periods.
Low-temperature performance is another important advantage. Current Celanese data lists a brittleness temperature of approximately -60°C.
This supports applications in cold climates and helps the grade remain useful in automotive, outdoor and industrial components that must tolerate low-temperature exposure.
Compression-set performance is approximately 41% at 70°C for 24 hours and approximately 47% at 125°C for 70 hours.
The grade also offers a high tear-strength value of approximately 35 kN/m, helping resist tearing around thin walls, edges, sealing lips and mechanically loaded sections.
Current thermal data lists an electrical Relative Thermal Index of approximately 100°C at 1.5 mm, a mechanical-strength RTI of approximately 95°C at 1.5 mm, and approximately 100°C at 3.0 mm.
Santoprene 201-80 is UL recognized under current Celanese references QMFZ2.E80017 and QMFZ8.E80017.
The current grade data also lists detergent-resistance ratings of f3 under UL 749 and f4 under UL 2157.
This does not make the grade a dedicated detergent-resistant appliance material, but it gives additional application context for parts exposed to cleaning environments.
The material is polyolefin based and Celanese states that it is recyclable within the manufacturing stream.

Why Choose Santoprene 201-80?
The main reason to choose Santoprene 201-80 is its combination of relatively high Shore A hardness and unusually high elongation.
At Shore A 86, the material is firm enough to provide significant structural support compared with softer TPV grades.
At the same time, the 540% elongation at break means the grade remains highly flexible and can accommodate large deformation.
The 11.1 MPa stress at break and 35 kN/m tear strength provide useful mechanical robustness.
Excellent flex-fatigue resistance supports components that move repeatedly during service.
Excellent ozone resistance is important for outdoor parts, automotive components and products exposed to atmospheric aging.
The -60°C brittleness temperature supports cold-weather service.
The natural, colorable appearance is another major advantage. Many black TPV grades are ideal for hidden technical parts, but visible consumer or appliance components may require white, gray, blue, red or another custom color.
Santoprene 201-80 provides a better starting point for such color programs than a black-only grade.
The material can also be processed through multiple conventional thermoplastic routes, helping manufacturers use existing equipment rather than investing in separate thermoset-rubber curing lines.
For customers requiring a natural, colorable, firm TPV with high elongation, strong tear resistance and broad processing flexibility, Santoprene 201-80 is a core grade to evaluate.

Shear-Dependent Flow
Santoprene 201-80 is a shear-dependent TPV.
As shear rate increases, apparent melt viscosity decreases. This means processors should optimize screw speed, injection speed, gate dimensions, back pressure, melt temperature, mold temperature, venting, die design, draw-down and cooling.
Regrind
The current grade data lists a maximum regrind level of approximately 20%.
Regrind should be dried before processing and should be controlled according to the customer’s quality, appearance and performance requirements.
Material Compatibility
Celanese states that Santoprene TPV is incompatible with acetal (POM) and PVC.
Equipment should be properly purged when changing between these materials and Santoprene 201-80.
