描述
Santoprene 8201-60 is a natural, colorable thermoplastic vulcanizate from Celanese designed as a general-purpose TPV for extrusion and molding applications.
The grade combines rubber-like flexibility with conventional thermoplastic processing and is particularly useful where manufacturers need:
- A natural base for custom coloring
- Moderate elastomeric softness
- Good elongation
- Flexible sealing performance
- Injection molding
- Extrusion
- Blow molding
- Good ozone resistance
- Good flex-fatigue resistance
Current Celanese Product Finder values include:
- 64 Shore A hardness
- Natural appearance
- 520% elongation at break
- 5.9 MPa tensile stress at break
- 2.2 MPa stress at 100% elongation
- 29% compression set at 70°C / 22 h
Santoprene 8201-60 belongs to Celanese’s Enhanced Colorability TPV Grades, making it particularly suitable for applications where black is not required and the finished component needs a custom color.
Its broad processability makes the grade relevant to:
- Injection-molded seals
- Soft grips
- Consumer components
- Appliance parts
- Extruded profiles
- Blow-molded flexible parts
Another important advantage is its non-hygroscopic behavior, so under proper storage conditions the material requires little or no drying compared with strongly hygroscopic engineering polymers.

These values give Santoprene 8201-60 a useful balance between flexibility and mechanical strength.
Low-Temperature Performance
Santoprene 8201-60 has a published brittleness temperature of approximately:
-60°C
This supports applications where the flexible component may experience low ambient temperatures.
Potential applications include:
- Outdoor consumer products
- Automotive components
- Cold-storage equipment
- Industrial seals
- Flexible protective parts
A brittleness temperature should not be treated as the guaranteed continuous operating limit, but it provides useful comparative low-temperature information.
Natural & Enhanced Colorability
A major feature of Santoprene 8201-60 is its Natural / enhanced-colorability formulation.
This makes it useful for components requiring:
- White
- Gray
- Blue
- Red
- Green
- Custom brand colors
- Color-coded technical parts
Potential applications include:
- Kitchen tools
- Appliance components
- Consumer electronics
- Stationery
- Soft-touch grips
- Household products
Compatible masterbatch should be selected to maintain:
- Mechanical performance
- Surface quality
- Flow
- Color uniformity
- Thermal stability
Non-Hygroscopic Behavior
Santoprene 8201-60 is specifically described as non-hygroscopic.
This means it does not absorb atmospheric moisture in the same way as materials such as:
- PA
- PET
- PBT
Under proper storage conditions, it normally requires little or no drying before processing.
This can reduce:
- Material preparation time
- Energy use
- Dryer demand
- Production start-up time
If pellets have been exposed to condensation or wet conditions, controlled drying may still be useful.
Ozone Resistance
Santoprene 8201-60 is recommended for applications requiring excellent ozone resistance.
This property is useful for flexible components exposed to:
- Outdoor atmosphere
- Electrical equipment
- Industrial environments
- Long-term environmental aging
Ozone resistance is particularly important for seals that remain mechanically strained over long periods.
Flex-Fatigue Resistance
The grade is also recommended where excellent flex-fatigue resistance is required.
This is useful for components exposed to repeated:
- Bending
- Stretching
- Compression
- Recovery
- Folding
- Mechanical cycling
Potential applications include:
- Flexible grips
- Strain reliefs
- Seals
- Repeated-motion components
- Flexible housings
Sealing Applications
Santoprene 8201-60 is specifically suitable for sealing applications.
Typical uses include:
- Housing seals
- Gaskets
- Flexible interfaces
- Protective seals
- Molded sealing rings
- Extruded sealing profiles
The combination of 64A hardness, 520% elongation and 29% compression set gives the grade a useful general-purpose sealing profile.
Electrical Properties
Historical Santoprene 8201-60 grade data also includes electrical-performance information.
| Property | Typical Rating |
|---|---|
| Comparative Tracking Index, CTI | PLC 0 |
| High Amp Arc Ignition, HAI | PLC 0 |
| High Voltage Arc Resistance, HVAR | PLC 5 |
| Hot Wire Ignition, 1.6 mm | PLC 3 |
| Hot Wire Ignition, 3.0 mm | PLC 2 |
These values can be useful when evaluating the material for:
- Cable accessories
- Strain reliefs
- Flexible electrical components
- Protective housings
Flammability
Published historical data gives:
| Thickness | UL 94 Rating |
|---|---|
| 1.1 mm | HB |
| 1.6 mm | HB |
| 3.0 mm | HB |
Santoprene 8201-60 should therefore be treated as an HB material, not as a V-0 flame-retardant grade.
Relative Temperature Index
Historical electrical data includes:
| Property | Typical Value |
|---|---|
| RTI Electrical | 100°C |
| RTI Mechanical Strength, 1.1 mm | 90°C |
| RTI Mechanical Strength, 1.6 mm | 90°C |
| RTI Mechanical Strength, 3.0 mm | 95°C |
These historical ratings are useful for reference, although current certification should be confirmed if the customer requires a specific UL-recognized construction.
Heat-Aging Performance
Historical grade-specific testing after 150°C for 168 hours showed approximately:
| Property | Typical Change |
|---|---|
| Tensile Strength | -9% |
| Elongation at Break | -7% |
| Shore A Hardness | +1 point |
| Mass | -8% |
These results provide useful information on property retention under the specified test condition.
They should not be interpreted as a universal 150°C continuous-service rating.

- Die geometry
rather than simply increasing melt temperature.
This characteristic is useful for:
- Thin molded sections
- Flexible sealing lips
- Detailed profiles
- Small gates

Multi-Injection Molding
Santoprene 8201-60 also supports multi-injection molding.
Potential applications include:
- Hard/soft parts
- Flexible interfaces
- Consumer grips
- Integrated sealing features
Actual adhesion to another polymer should be verified using the exact substrate grade.
Santoprene 8201-60 should not automatically be marketed as a dedicated bondable overmolding grade like the B100 or B150 families.
Blow Molding
The grade can also be used in:
- Blow molding
- Extrusion blow molding
This broad processing capability makes Santoprene 8201-60 useful for flexible hollow components where elastomeric behavior is desired.
Material Compatibility
Santoprene TPV processing guidance states that it is incompatible with:
- POM / Acetal
- PVC
Processing equipment should be thoroughly purged when changing between these polymers and Santoprene 8201-60.
Manufacturing-Stream Recyclability
Santoprene 8201-60 is polyolefin based and suitable for controlled manufacturing-stream recycling.
Published guidance allows approximately:
Up to 20% regrind
as a processing reference.
Possible clean process scrap includes:
- Sprues
- Runners
- Profile trim
- Start-up material
- Selected rejected parts
The final regrind level should be controlled according to:
- Mechanical-performance requirements
- Appearance
- Color consistency
- Final qualification requirements
