描述
Santoprene 101-87 is a hard, black and versatile thermoplastic vulcanizate (TPV) from Celanese designed for demanding general-purpose molding and extrusion applications.
Celanese describes the grade as a TPV in the thermoplastic elastomer family that combines good physical properties and chemical resistance with conventional thermoplastic processing.
A particularly important point is that the grade designation 101-87 should not be interpreted as the current measured Shore A hardness. The current Celanese Materials Database lists a Shore A hardness of approximately 94 after 15 seconds. For material selection, use the current published property value rather than assuming hardness from the grade number.
The material combines rubber-like elasticity with the processing efficiency of thermoplastics.
Celanese specifically identifies excellent flex-fatigue resistance and excellent ozone resistance as key features of Santoprene 101-87.
These properties support applications that experience repeated bending, vibration, deformation, weather exposure or ozone over long service periods.
Compared with softer Santoprene 101-series grades, Santoprene 101-87 provides a much firmer elastomeric response and substantially higher tensile and tear strength.
Current Celanese data lists approximately 15.6 MPa stress at break, 6.93 MPa stress at 100% elongation, 597% elongation at break and approximately 51 kN/m tear strength.
The combination is notable because the grade retains very high elongation despite its high Shore A hardness.
Low-temperature performance remains strong for such a hard TPV. Current grade data lists approximately -54°C brittleness temperature under both ASTM and ISO references.
Compression set is approximately 37% at 70°C for 24 hours and 52% at 125°C for 70 hours.
The density is approximately 0.950 g/cm³, keeping the material substantially lighter than many conventional rubbers and several other engineering elastomers.
Santoprene 101-87 is also highly versatile in processing. Celanese states that it can be processed on conventional thermoplastic equipment by injection molding, extrusion, blow molding, thermoforming and vacuum forming.
The material is polyolefin based and can be recyclable within the manufacturing stream under properly controlled production conditions.
Current Celanese documentation also lists UL recognition under QMFZ2.E80017, QMFZ8.E80017, and QMTT2.E86313 for polymeric materials used in wire, cable and flexible lighting product components.
The grade carries outdoor suitability f1 under UL 746C and detergent-resistance ratings of f3 under UL 749 and f4 under UL 2157.

Typical Properties of Santoprene 101-87
Physical Properties
| Property | Typical Value | Test Method |
|---|---|---|
| Density | 950 kg/m³ / 0.950 g/cm³ | ISO 1183 |

The unusually high combination of Shore A 94 hardness and 597% elongation gives Santoprene 101-87 a distinctive position among general-purpose TPV grades.
Thermal Properties
| Property | Typical Value | Test Method |
|---|---|---|
| RTI Electrical, 1.5 mm | 90°C | UL 746B |
| RTI Strength, 1.5 mm | 90°C | UL 746B |

Why Choose Santoprene 101-87?
The main reason to select Santoprene 101-87 is that it provides a much firmer elastomeric response than the softer 101-series grades while retaining excellent stretch and flexibility.
A conventional high-hardness thermoplastic can provide stiffness but may not provide the elastic recovery, ozone resistance or flex-fatigue behavior needed for sealing and protective components.
A softer TPV may provide excellent recovery but can deform too much when the design requires dimensional support.
Santoprene 101-87 bridges this gap.
Its current Shore A hardness of approximately 94 gives the material a very firm rubber-like feel.
Its stress at break of approximately 15.6 MPa and tear strength of approximately 51 kN/m support applications with high mechanical loading.
At the same time, elongation remains approximately 597%, allowing large deformation without the brittle behavior of many rigid thermoplastics.
Excellent flex-fatigue resistance is important for clips, bellows, boots and protective components that repeatedly bend or move.
Excellent ozone resistance supports long-term outdoor and automotive exposure.
The -54°C brittleness temperature provides useful cold-weather capability despite the grade’s high hardness.
Thermoplastic processing allows shorter manufacturing cycles than many conventional cured rubber systems.
For customers who need a hard black TPV with strong tensile and tear properties, high elongation and extensive automotive qualification history, Santoprene 101-87 is a core grade to evaluate.

Shear-Dependent Flow
Santoprene 101-87 is shear dependent.
As shear rate increases, apparent melt viscosity decreases. This behavior means processors should optimize:
- Screw speed
- Injection speed
- Gate size
- Back pressure
- Melt temperature
- Venting
- Cooling
- Extrusion die design
- Draw-down ratio
- Surface finish
Higher shear can improve flow, so increasing processing temperature is not always the only or best way to improve filling.
Material Compatibility
Celanese states that Santoprene TPV is incompatible with acetal (POM) and PVC.
Processing equipment should be properly purged when switching between these materials and Santoprene 101-87.
