描述
Santoprene 101-80 is a black, versatile thermoplastic vulcanizate (TPV) from Celanese designed for general-purpose extrusion and molding applications that require a relatively firm elastomeric response together with high elongation and durable rubber-like performance.
Celanese places the grade in its core Santoprene 101 general-purpose series. The official Santoprene product finder describes this family as suitable for extrusion and molding while offering the highest level of elastomeric properties within the general-purpose grade group.
The current Shore A hardness of Santoprene 101-80 is approximately 87, even though the grade designation contains “80.” The grade name should therefore not be interpreted as the current ISO Shore A value.
This distinction is important because customers sometimes compare the model number directly with hardness. Current Celanese data identifies the standard 101-80 grade at Shore A 87.
The material combines vulcanized-rubber-like elasticity with thermoplastic processing behavior. It can be processed on conventional thermoplastic equipment without a separate curing step during normal conversion.
Celanese specifically identifies excellent flex-fatigue resistance and excellent ozone resistance as key features of Santoprene 101-80.
These characteristics are valuable for parts exposed to repeated bending, vibration, cyclic deformation, outdoor weathering and automotive under-hood conditions.
Current grade data lists approximately 526% elongation at break, 10.4 MPa stress at break, 4.61 MPa stress at 100% elongation and approximately 33 kN/m tear strength.
This is a strong mechanical profile for a TPV with high elastomeric hardness. It gives designers more tensile and tear resistance than softer 101-series grades while preserving substantial extensibility.
Low-temperature flexibility is also strong. The current brittleness temperature is approximately -60°C, supporting automotive, outdoor and industrial use in cold environments.
Compression-set performance is approximately 36% at 70°C for 24 hours and 52% at 125°C for 70 hours.
Because compression set generally rises as TPV hardness increases, customers should evaluate sealing force, geometry and long-term deformation together rather than selecting the grade only by hardness.
The material density is approximately 0.960 g/cm³, helping provide lower part weight than many traditional rubber systems.
Santoprene 101-80 is also UL recognized. Current Celanese-derived documentation references:
- QMFZ2.E80017 – Plastics Component
- QMFZ8.E80017 – Plastics Certified for Canada
- QMTT2.E86313 – Polymeric Materials for Use in Wire, Cable and Flexible Lighting Products
The grade also carries outdoor suitability f1 under UL 746C and detergent-resistance ratings of f3 under UL 749 and f4 under UL 2157.
Current automotive approval references include Ford WSD-M2D381-A1, GM GMW15813 Type 7, Mercedes-Benz DBL 5562, Hyundai MS220-05 Type D, Volkswagen Group VW50123, Renault references and Stellantis specifications.
This combination of mechanical strength, broad processability and OEM history makes Santoprene 101-80 suitable for demanding automotive and industrial elastomeric components.

Why Choose Santoprene 101-80?
The main reason to choose Santoprene 101-80 is its combination of high elastomeric hardness and very high elongation.
At Shore A 87, the material is significantly firmer than Santoprene 101-73, yet it still reaches approximately 526% elongation at break.
The stress at break of approximately 10.4 MPa and tear strength of approximately 33 kN/m provide useful mechanical durability for parts that must hold shape, resist tearing and tolerate repeated deformation.
Excellent flex-fatigue resistance is valuable for bellows, boots and ducts.
Excellent ozone resistance makes the grade useful in outdoor, automotive and under-hood environments.
The -60°C brittleness temperature supports cold-weather service.
Its UL recognition, electrical data and wire/cable component listing broaden its use beyond purely mechanical automotive parts.
Thermoplastic processing is another major advantage. Injection molding, extrusion, blow molding, thermoforming and vacuum forming are all supported.
Compared with thermoset rubber, a TPV can simplify production by eliminating a separate vulcanization step and allowing controlled process scrap to be recycled within the manufacturing stream.
For customers requiring a firm black TPV with high tensile strength, high elongation, excellent ozone resistance and strong automotive history, Santoprene 101-80 is a core grade to evaluate.
Processing Guidelines for Santoprene 101-80
Santoprene 101-80 can be processed by:
- Injection molding
- Multi-injection molding
- Extrusion
- Profile extrusion
- Sheet extrusion
- Coextrusion
- Blow molding
- Thermoforming
- Vacuum forming
Grade-Specific Injection Conditions
| Processing Parameter | Celanese Guidance |
|---|---|
| Drying Temperature | 82°C |
| Drying Time | 3 hours in a dehumidified dryer |
| Processing Moisture Content | ≤0.08% |
| Maximum Regrind Level | 20% |
| Optimum Melt Temperature | 215°C |
| Mold Temperature Range | 10–52°C |
| Vent Depth | 25 µm |
| Back Pressure | 0.345–0.689 MPa |
| Injection Speed | Fast |
Celanese recommends drying for approximately 3 hours at 80–82°C before processing.
Extrusion Conditions
| Processing Parameter | Celanese Guidance |
|---|---|
| Drying Temperature | 82°C |
| Drying Time | 3 hours |
| Melt Temperature Reference | 202°C |
Celanese also gives a broad Santoprene TPV processing window of approximately 175–230°C.
Shear-Dependent Flow Behavior
Santoprene TPV is strongly shear dependent. As shear rate increases, apparent melt viscosity decreases.
Processors should therefore optimize:
- Screw speed
- Injection speed
- Gate dimensions
- Back pressure
- Melt temperature
- Mold temperature
- Venting
- Cooling time
- Extrusion die geometry
- Draw-down and profile cooling
This behavior means that flow cannot be optimized by temperature alone.
Material Compatibility
Celanese states that Santoprene TPV is incompatible with acetal (POM) and PVC.
When changing materials, barrels, screws, hot runners, dies and other melt-contact surfaces should be properly purged.
Santoprene 101-80 vs. Santoprene 101-73
| Feature | Santoprene 101-80 | Santoprene 101-73 |
|---|---|---|
| Material Family | TPV | TPV |
| Color | Black | Black |
| Product Positioning | General purpose | General purpose |
| Shore A Hardness | 87 | 78 |
| Elongation at Break | 526% | 478% |
| Stress at Break | 10.4 MPa | 7.98 MPa |
| Stress @ 100% Elongation | 4.61 MPa | 3.44 MPa |
| Tear Strength | 33 kN/m | 25 kN/m |
| Compression Set, 70°C / 24 h | 36% | 27% |
| Brittleness Temperature | -60°C | -60°C |
| Main Selection Difference | Higher hardness, strength and tear resistance | Softer with lower compression set |
Choose Santoprene 101-80 when greater hardness, tensile strength and tear resistance are required.
Choose Santoprene 101-73 when a softer elastomer with lower compression set is more important.
Santoprene 101-80 vs. Santoprene 101-80 ECO-R
The standard Santoprene 101-80 and Santoprene 101-80 ECO-R are separate grades and should not be treated as identical materials.
Celanese’s ECO-R product uses a minimum level of post-consumer recycled material and has its own published property set.
The standard Santoprene 101-80 current grade data lists approximately Shore A 87, while the separately published 101-80 ECO-R material is listed at approximately Shore A 80.
Customers should therefore request the exact TDS corresponding to the grade name shown on the purchase order and packaging.
