描述
Santoprene 201-87 is a hard, colorable thermoplastic vulcanizate developed for applications requiring a combination of high mechanical strength, rubber-like elasticity and efficient thermoplastic processing.
The grade has a typical hardness of approximately 93 Shore A, placing it in the high-hardness range of Santoprene TPV materials.
Despite its relatively high hardness, Santoprene 201-87 retains substantial elasticity. Typical material data lists approximately 580% elongation at break, making it suitable for components that must withstand significant deformation without behaving like a rigid engineering plastic.
Its typical tensile stress at break is approximately 15 MPa, while tensile stress at 100% elongation is approximately 7.1 MPa.
Santoprene 201-87 also provides approximately 48 kN/m tear strength, giving the material good resistance to crack propagation, edge damage and tearing in demanding molded and extruded parts.
Excellent flex-fatigue resistance is one of the important characteristics of this grade. It can therefore be considered for components exposed to repeated bending, deformation, compression or movement during service.
The material also offers excellent ozone resistance, which is valuable for automotive, outdoor and industrial applications where elastomeric components may be continuously exposed to air and environmental aging.
Low-temperature performance is supported by a typical brittleness temperature of approximately -54°C.
Santoprene 201-87 combines these elastomeric properties with conventional thermoplastic processing, allowing manufacturers to use injection molding, extrusion, blow molding, thermoforming and vacuum-forming equipment.
Because the grade is supplied as a natural / colorable material, it also provides greater design flexibility for applications requiring customized color identification or appearance.

Flex-Fatigue and Ozone Resistance
One of the most important advantages of Santoprene 201-87 is its resistance to repeated flexing.
Components such as boots, bellows, gaskets, flexible housings and sealing profiles may experience thousands or millions of deformation cycles during service.
Excellent flex-fatigue resistance helps the material maintain its mechanical integrity under this type of cyclic loading.
Ozone resistance is also important for components exposed to outdoor air, automotive environments and long-term atmospheric aging.
Traditional elastomers can suffer surface cracking when exposed to ozone under strain. Santoprene TPV materials are widely selected where improved environmental resistance is required.
Low-Temperature Performance
Santoprene 201-87 has a typical brittleness temperature of approximately -54°C.
This means the material can retain useful flexibility at temperatures far below room temperature.
Such behavior can be valuable for:
- Cold-climate automotive components
- Outdoor seals
- Industrial equipment
- Flexible protective parts
- Weather-exposed profiles
- Transportation components
Low-temperature requirements should always be considered together with component geometry, loading conditions and actual service environment.
Compression Set Performance
Compression set is an important parameter for sealing applications because it indicates how effectively an elastomer recovers after being compressed for an extended period.
Santoprene 201-87 shows typical compression-set values of approximately:
- 36% at 70°C for 24 hours
- 44% at 125°C for 70 hours
This makes the grade suitable for selected seals, gaskets and compressed elastomeric components where a combination of hardness and recovery is required.
Chemical and Environmental Resistance
Santoprene 201-87 provides good resistance to many chemicals commonly encountered in automotive, industrial and appliance environments.
The polyolefin-based TPV structure also contributes to good moisture and environmental resistance.
Typical applications may involve exposure to:
- Water
- Detergent environments
- Automotive fluids
- Atmospheric ozone
- Outdoor weathering
- Industrial environments
Actual chemical compatibility should be evaluated according to chemical concentration, exposure time, temperature and mechanical stress.
Processing Guidelines for Santoprene 201-87
Santoprene 201-87 can be processed using conventional thermoplastic equipment.
Suitable processing methods include:
- Injection molding
- Extrusion
- Blow molding
- Thermoforming
- Vacuum forming
Typical Processing Guidance
| Processing Parameter | Typical Guidance |
|---|---|
| Drying Temperature | 80–82°C |
| Drying Time | Approx. 3 hours |
| Maximum Processing Moisture | 0.08% |
| Maximum Regrind Level | 20% |
| Mold Temperature | 10–52°C |
| Back Pressure | 0.345–0.689 MPa |
| Injection Speed | Fast |
| Vent Depth | 25 µm |
| Extrusion Melt Temperature Reference | 204°C |
| General Santoprene TPV Processing Window | 175–230°C |
Santoprene TPV exhibits shear-dependent flow behavior, meaning apparent melt viscosity decreases as shear rate increases.
This behavior makes injection speed, gate geometry, screw speed and melt temperature important processing variables.
Injection Molding Considerations
For injection molding, processors should optimize:
- Melt temperature
- Mold temperature
- Injection speed
- Screw speed
- Back pressure
- Gate dimensions
- Runner dimensions
- Venting
- Cooling time
- Part thickness
- Shrinkage
Fast injection is often useful for achieving good filling and surface quality.
Mold design should provide sufficient venting to avoid trapped air and surface defects.
Extrusion Considerations
For extrusion, important variables include:
- Barrel-zone temperature
- Adapter temperature
- Die temperature
- Screw speed
- Melt pressure
- Draw-down
- Cooling rate
- Profile dimensions
- Surface finish
Extrusion parameters should be adjusted according to profile thickness, die geometry and required dimensional stability.
Material Changeover
Santoprene TPV should not be mixed with incompatible materials during processing.
Equipment should be properly purged when changing materials to help avoid contamination, degradation and processing instability.
Why Use Santoprene 201-87?
Santoprene 201-87 offers an attractive combination of properties for manufacturers that require a firm elastomeric material.
