描述
Santoprene 203-50 OG is a hard, colorable thermoplastic vulcanizate from Celanese designed for applications requiring a combination of elastomeric durability and conventional thermoplastic processing.
The grade is part of the Santoprene TPV family and is described as a versatile material combining good physical properties and chemical resistance for use across a wide range of applications.
Santoprene 203-50 OG is a shear-dependent TPV. This means its melt-flow behavior changes significantly with shear rate, an important consideration when optimizing injection speed, screw speed, gate design and extrusion conditions.
The material can be processed using conventional thermoplastic equipment rather than requiring a separate vulcanization stage.
Current Celanese-derived data lists the following processing methods for Santoprene 203-50 OG:
- Injection molding
- Multi-injection molding
- Extrusion
- Profile extrusion
- Sheet extrusion
- Blow molding
- Thermoforming
- Vacuum forming
Independent commercial listings also identify extrusion blow molding, profile extrusion, sheet extrusion and injection molding as applicable processes for this exact grade.
Two particularly important characteristics of Santoprene 203-50 OG are:
- Excellent ozone resistance
- Excellent thermal resistance
These properties make the grade useful for automotive, outdoor, industrial and technical components that may experience environmental aging or elevated temperatures.
The material is polyolefin based and is described as recyclable within the manufacturing stream.

Published Property Categories for Santoprene 203-50 OG
Current public Celanese-derived listings identify the following physical and mechanical property categories for Santoprene 203-50 OG:
Physical Properties
| Property | Published Status |
|---|---|
| Density | Published in grade data |
| Shore D Hardness | Published in grade data |
| Material Family | TPV |
| Filler | Unfilled |
| Colorability | Colorable |
| Polymer Base | Polyolefin based |
Mechanical Properties
| Property | Published Status |
|---|---|
| Tensile Strength at Yield | Published in grade data |
| Elongation at Yield | Published in grade data |
| Tear Strength | Published in grade data |
| Compression Set | Published in grade data |
| Brittleness Temperature | Published in grade data |
The publicly indexed Celanese-derived page confirms that these properties are part of the 203-50 OG technical dataset, but the numeric values are not exposed in the indexed text version.
For this reason, I would not copy the numeric values from standard Santoprene 203-50 into the 203-50 OG page unless the current OG TDS confirms they are identical.
Ozone Resistance
One of the most clearly documented characteristics of Santoprene 203-50 OG is its excellent ozone resistance.
Ozone resistance is important for elastomeric components that may be exposed to:
- Outdoor air
- Automotive environments
- Weathering
- Mechanical strain
- Long service periods
Traditional elastomers may develop surface cracking under ozone exposure, particularly when components remain stretched or compressed.
Santoprene TPV is designed to provide strong environmental durability, and excellent ozone resistance is specifically identified for the 203-50 OG grade.
Thermal Resistance
Santoprene 203-50 OG is also specifically described as offering excellent thermal resistance.
This characteristic expands its usefulness in applications such as:
- Automotive technical components
- Under-hood parts
- Industrial equipment
- Appliance components
- Electrical and electronic protection
- Elevated-temperature molded components
The exact continuous-use and short-term temperature limits should be selected from the current grade-specific technical data.
Chemical Resistance
Santoprene 203-50 OG combines good physical properties with good chemical resistance.
This can make the material suitable for applications exposed to selected:
- Automotive fluids
- Water
- Cleaning environments
- Industrial chemicals
- Oils and lubricants
- Outdoor contamination
Chemical resistance always depends on exposure temperature, concentration, duration and mechanical stress.
Processing Guidelines for Santoprene 203-50 OG
Santoprene 203-50 OG can be processed on conventional thermoplastic equipment.
Current published processing methods include:
- Injection molding
- Multi-injection molding
- Extrusion
- Profile extrusion
- Sheet extrusion
- Blow molding
- Thermoforming
- Vacuum forming
Shear-Dependent Flow
Santoprene 203-50 OG is specifically described as a shear-dependent TPV.
As shear rate increases, apparent viscosity typically decreases.
Important injection-molding variables therefore include:
- Injection speed
- Screw speed
- Melt temperature
- Mold temperature
- Back pressure
- Gate dimensions
- Runner design
- Venting
- Holding pressure
- Cooling time
For extrusion, important variables include:
- Barrel-zone temperature
- Adapter temperature
- Die temperature
- Screw speed
- Melt pressure
- Draw-down
- Cooling
- Profile geometry
- Surface finish
The exact grade-specific temperature settings should be taken from the current Santoprene 203-50 OG TDS or processing data, rather than copied directly from standard 203-50.
Why Choose Santoprene 203-50 OG?
The main reason to evaluate Santoprene 203-50 OG is its combination of a hard elastomeric response and broad manufacturing flexibility.
It offers the durability expected from a dynamically vulcanized TPV while retaining the ability to be processed on standard thermoplastic equipment.
Excellent ozone resistance supports weather-exposed and automotive components.
Excellent thermal resistance broadens its usefulness in elevated-temperature environments.
Good chemical resistance supports many industrial and automotive applications.
Its colorable formulation provides additional freedom for product appearance and component identification.
Injection molding, extrusion, blow molding, thermoforming and vacuum forming provide substantial manufacturing flexibility.
For applications requiring a hard, colorable Santoprene TPV with excellent ozone and thermal resistance, Santoprene 203-50 OG is a grade worth evaluating.
