描述
Santoprene 241-64 is a soft, natural and colorable specialty thermoplastic vulcanizate from Celanese developed for applications involving potable-water contact and food-processing equipment.
The grade is part of the Santoprene 241 food- and water-contact family and is specifically certified to NSF/ANSI Standard 51 for materials and components used in food equipment and NSF/ANSI Standard 61 for drinking-water system components.
This makes Santoprene 241-64 particularly relevant for plumbing systems, drinking-water components, food-processing equipment, seals, gaskets and other elastomeric parts where material compliance is a key selection requirement.
The grade has a typical hardness of approximately 69 Shore A, giving it a useful balance between softness, sealing performance and dimensional support.
Current Celanese Product Finder data lists approximately 450% elongation at break, 7.0 MPa tensile stress at break and approximately 2.6 MPa tensile stress at 100% elongation.
These values show that Santoprene 241-64 remains highly flexible while providing sufficient mechanical strength for demanding molded and extruded components.
The grade is also described as having excellent flex-fatigue resistance, making it suitable for parts exposed to repeated bending, compression or deformation.
Like other Santoprene TPV materials, it also provides strong ozone and weathering resistance, chemical resistance and good elastic recovery over a broad temperature range.
Santoprene 241-64 is a shear-dependent TPV and can be processed on conventional thermoplastic equipment using injection molding, extrusion or blow molding.
The material is polyolefin based and recyclable within the manufacturing stream.

NSF/ANSI 51 Food Equipment Certification
One of the most important reasons to specify Santoprene 241-64 is its NSF/ANSI Standard 51 certification.
NSF/ANSI 51 covers materials and components used in commercial food equipment.
For material selection, this certification is particularly relevant to applications such as:
- Food-processing equipment
- Beverage equipment
- Food-contact seals
- Gaskets
- Flexible connectors
- Water-handling components in food equipment
Celanese specifically identifies Santoprene 241-64 as NSF 51 certified for materials used in food equipment.
NSF/ANSI 61 Potable Water Certification
Santoprene 241-64 is also certified to NSF/ANSI Standard 61.
This standard addresses health effects associated with components used in drinking-water systems.
This certification makes the grade relevant for selected applications involving:
- Potable-water systems
- Plumbing components
- Drinking-water seals
- Valve components
- Flexible water-handling parts
- Connectors and fittings
- Water-treatment equipment
The combination of NSF 51 and NSF 61 is one of the defining differences of the 241-64 grade.
Flex-Fatigue and Environmental Resistance
Santoprene 241-64 is recommended for applications requiring excellent flex-fatigue resistance.
This characteristic is important for components that repeatedly:
- Bend
- Compress
- Expand
- Move
- Seal
- Recover after deformation
The broader Santoprene TPV family also provides strong resistance to ozone, weathering, chemicals and oils, together with high elastic recovery.
These characteristics can be valuable in long-term plumbing and food-equipment service.
Processing Guidelines for Santoprene 241-64
Santoprene 241-64 can be processed using conventional thermoplastic equipment.
Current grade information lists:
- Injection molding
- Multi-injection molding
- Extrusion
- Profile extrusion
- Sheet extrusion
- Extrusion blow molding
- Injection blow molding
Extrusion Conditions
| Processing Parameter | Published Guidance |
|---|---|
| Drying Temperature | 82°C |
| Drying Time | 3 hours |
| Melt Temperature | 196°C |
| Die Temperature | 199°C |
| Back Pressure | 5–20 MPa |
Historical grade-specific Santoprene 241-64 processing data gives approximately 82°C for 3 hours drying, 196°C melt temperature and approximately 199°C die temperature for extrusion.
Shear-Dependent Flow
Santoprene 241-64 is a shear-dependent TPV.
As shear rate increases, apparent melt viscosity decreases.
Processors should therefore optimize:
- Screw speed
- Injection speed
- Gate dimensions
- Melt temperature
- Die temperature
- Back pressure
- Extrusion pressure
- Cooling conditions
- Profile dimensions
- Surface finish
Material Compatibility
Historical processing information states that Santoprene TPV is incompatible with acetal (POM) and PVC.
Equipment should therefore be thoroughly purged when changing between these materials and Santoprene 241-64.
UL & Flammability Information
Current material listings identify Santoprene 241-64 as UL recognized under:
- QMFZ2.E80017
- QMFZ8.E80017
The grade has a typical UL 94 HB classification at published thicknesses including 1.0 mm and 1.5 mm.
Santoprene 241-64 is not positioned as a dedicated flame-retardant TPV. Its main advantages are food- and potable-water certification, elastomeric performance and thermoplastic processability.
Why Choose Santoprene 241-64?
The main reason to choose Santoprene 241-64 is its combination of regulatory compliance and elastomeric performance.
Its 69 Shore A hardness provides a useful level of flexibility for seals, gaskets and molded components.
Approximately 450% elongation at break supports large deformation without requiring a very soft material.
The approximately 7.0 MPa tensile stress at break provides useful mechanical strength.
Excellent flex-fatigue resistance supports components that repeatedly move or compress.
Most importantly, NSF/ANSI 51 and NSF/ANSI 61 certification make the grade suitable for applications where food-equipment or drinking-water compliance is part of the material selection process.
The grade can also be processed by standard thermoplastic injection molding, extrusion and blow molding methods.
For customers requiring a natural, colorable 69A TPV for food-equipment or potable-water applications, Santoprene 241-64 is an important grade to evaluate.
