描述
Santoprene 101-73E100 is a black thermoplastic vulcanizate (TPV) grade from Celanese designed as a versatile elastomeric material for a broad range of technical applications.
Current Celanese-derived public material information describes Santoprene 101-73E100 as a soft, black and versatile TPV that combines good physical properties and chemical resistance with the processing advantages of conventional thermoplastics.
The two grade-specific performance features highlighted in the current public record are excellent flex-fatigue resistance and excellent ozone resistance.
These properties make Santoprene 101-73E100 relevant to parts that experience repeated bending, compression, vibration, flexing or environmental exposure during service.
The material is polyolefin based and behaves like a rubber while being processed as a thermoplastic. That combination is the central advantage of Santoprene TPV technology.
Unlike conventional thermoset EPDM rubber, Santoprene 101-73E100 does not require a separate vulcanization step during normal thermoplastic processing. This can simplify production, shorten processing sequences and enable recycling of suitable manufacturing scrap within a controlled production stream.
Current grade-level information lists a broad range of processing technologies:
- Injection molding
- Extrusion
- Blow molding
- Thermoforming
- Vacuum forming
This makes Santoprene 101-73E100 useful for molded components, extruded profiles, flexible tubes, hollow parts, sheet-based parts and technical elastomeric components.
The grade is also described as shear dependent. As with other Santoprene TPV materials, apparent melt viscosity decreases as shear rate increases. Processors therefore need to consider screw speed, injection speed, gate design, die geometry and shear history rather than relying on temperature alone to control flow.
Celanese’s current Santoprene portfolio describes TPV technology as offering sealing performance, ozone and weathering resistance, chemical and oil resistance, elastic recovery over a wide temperature range, high flex-fatigue resistance and thermoplastic processability.
These family-level characteristics support the positioning of Santoprene 101-73E100, but grade-specific selection should still be based on the exact current grade data and application conditions.
An important point for buyers is that the current Celanese all-grades Product Finder lists Santoprene 101-73 in the general-purpose family, while the exact 101-73E100 designation is separately present in current Celanese-derived technical databases. The public Product Finder does not explain the E100 suffix or state that the two grades are numerically identical.
For that reason, the property values of standard 101-73 should not automatically be copied onto Santoprene 101-73E100. This page keeps the exact grade identity separate and uses only properties that are supported for the E100 designation.

Santoprene 101-73E100 and the 101-73 General-Purpose Family
The current Celanese Product Finder places standard Santoprene 101-73 in the general-purpose TPV family.
For reference, the current official Product Finder reports the following values for standard 101-73, not for E100:
| Property | Santoprene 101-73 Reference |
|---|---|
| Hardness | Shore A 78 |
| Elongation at Break | 478% |
| Tensile Strength at Break | 8.0 MPa |
| Tensile Stress at 100% Elongation | 3.4 MPa |
| Compression Set, 70°C | 27% |
| Appearance | Black |
| Positioning | General-purpose extrusion and molding grade |
These values are useful for understanding the performance region of the 101-73 family, but they should not be presented as certified Santoprene 101-73E100 values unless the exact current E100 TDS confirms them.
This distinction is important for automotive approvals, regulated applications, engineering calculations and customer specification work.
Why Choose Santoprene 101-73E100?
Santoprene 101-73E100 is attractive when the application requires a black TPV with broad processing options and durable elastomeric behavior.
Flex-Fatigue Resistance
Repeated bending is demanding on elastomers.
Bellows, boots, flexible ducts, diaphragms and sealing lips can experience thousands or millions of movement cycles during service. Celanese specifically identifies excellent flex-fatigue resistance as a key feature of Santoprene 101-73E100.
Ozone Resistance
Ozone can cause cracking and surface degradation in susceptible rubber materials.
Excellent ozone resistance makes Santoprene 101-73E100 relevant to outdoor, automotive and industrial applications where long-term atmospheric exposure is expected.
Chemical Resistance
The grade is described as combining good physical properties with chemical resistance.
This makes it useful for technical components exposed to compatible oils, cleaners, water-based fluids or industrial environments, subject to actual chemical compatibility testing.
Thermoplastic Processing
Traditional thermoset rubber production can require mixing, curing and secondary trimming operations.
Santoprene TPV is supplied as ready-to-process pellets and can be handled on conventional thermoplastic equipment.
For Santoprene 101-73E100, supported technologies include molding, extrusion, blow molding, thermoforming and vacuum forming.
Recycling Within the Manufacturing Stream
Celanese describes this grade as recyclable within the manufacturing stream.
This gives processors an opportunity to reduce scrap compared with fully crosslinked thermoset rubber, provided regrind is controlled according to part-performance and quality requirements.
Processing Guidelines for Santoprene 101-73E100
Current grade information confirms that Santoprene 101-73E100 is suitable for multiple thermoplastic processes.
Supported Processes
- Injection molding
- Extrusion
- Blow molding
- Thermoforming
- Vacuum forming
Shear-Dependent Processing Behavior
One of the most important processing characteristics of Santoprene 101-73E100 is shear dependence.
As shear increases, apparent viscosity decreases. This means process optimization should focus on the interaction of:
- Screw speed
- Injection speed
- Gate dimensions
- Runner design
- Die geometry
- Back pressure
- Melt temperature
- Mold or cooling temperature
- Cooling rate
- Part wall thickness
A processor should not assume that increasing barrel temperature is always the best way to improve filling.
Higher shear through optimized screw speed, gate design or injection velocity can significantly change flow behavior.
Family-Level Santoprene Processing Context
Celanese describes Santoprene TPV as easy to process on conventional thermoplastic equipment and lists injection molding, blow molding, extrusion, physical foaming, chemical foaming and calendaring across the product family.
Celanese technical literature for Santoprene also commonly references processing temperatures around 200°C as a practical family-level context.
This should be treated as family guidance, not a replacement for the exact Santoprene 101-73E100 processing table.
Drying and Regrind
The exact grade record includes drying temperature, drying time and maximum-regrind entries.
For production setup, use the current grade-specific Celanese TDS values rather than transferring values from standard 101-73 or another E100 grade.
Purging and Contamination Control
Good contamination control is important when processing TPV.
Before production:
- Clean the hopper and feed system
- Remove incompatible resin residues
- Purge the barrel and screw
- Clean the die or hot runner
- Control regrind separately
- Keep color or additive additions consistent
Stable material handling helps maintain surface quality and mechanical consistency.
