Key Features of Santoprene 6SD001A30 NAT

Typical Applications for Santoprene 6SD001A30 NAT

Because of its very low hardness, Santoprene 6SD001A30 NAT is particularly suitable for applications where softness and flexible deformation are more important than high structural stiffness.

Santoprene 6SD001A30 NAT is particularly useful where a conventional rigid thermoplastic would be too stiff and a separate thermoset-rubber process would add unnecessary manufacturing complexity.

Typical Properties of Santoprene 6SD001A30 NAT

Physical Properties

The grade name contains A30, but the current published laboratory value is 28 Shore A. For technical accuracy, the webpage should therefore use 28 Shore A rather than automatically calling the material 30A.

Mechanical Properties

These values show that Santoprene 6SD001A30 NAT is a low-modulus, high-flexibility TPV rather than a high-strength structural elastomer.

Thermal Properties

Santoprene 6SD001A30 NAT also has published coefficient-of-linear-thermal-expansion data.

These values can help engineers estimate dimensional movement when the molded part experiences temperature changes.

For components with tight dimensional tolerances, thermal expansion should be considered together with:

• Part geometry
• Mold shrinkage
• Assembly design
• Service temperature
• Constraint from surrounding components

Ultra-Soft 28 Shore A Performance

One of the most important characteristics of Santoprene 6SD001A30 NAT is its very low hardness.

At approximately 28 Shore A, the material is suitable for applications requiring:

• Soft tactile response
• Easy compression
• High flexibility
• Large deformation
• Cushioning
• Flexible sealing
• Comfortable contact surfaces

The relatively low 0.7 MPa stress at 100% elongation confirms that the material requires comparatively low force to stretch.

This makes Santoprene 6SD001A30 NAT particularly useful where a softer elastomeric response is desired.

High Elongation

The published elongation at break is approximately:

422%

This means the test specimen can undergo substantial extension before break under the specified laboratory test conditions.

High elongation can be valuable for:

• Flexible seals
• Soft grommets
• Snap-over components
• Parts stretched during assembly
• Soft protective covers
• Components exposed to repeated deformation

The final part performance will also depend on geometry and molding conditions.

Compression Set

The grade-specific compression-set value is approximately:

27% at 70°C for 24 hours

Compression-set performance is important in sealing applications because a seal must recover after being held under compression.

Potential uses include:

• Soft gaskets
• Housing seals
• Flexible interfaces
• Compression pads
• Soft contact seals

The very soft 28A hardness can allow the material to conform well to mating surfaces.

Tear Resistance

Santoprene 6SD001A30 NAT provides approximately:

10 kN/m tear strength

Tear strength is important where the molded component includes:

• Thin edges
• Holes
• Slots
• Flexible lips
• Small radii
• Assembly features

Good part design should minimize sharp notches that may concentrate stress.

Natural / Colorable Appearance

Santoprene 6SD001A30 NAT is supplied as a Natural material.

This offers useful flexibility for customers requiring:

• White components
• Gray parts
• Custom colors
• Color-coded functional components
• Consumer-product aesthetics

When using color masterbatch, processors should confirm:

• Masterbatch compatibility
• Color concentration
• Mechanical-property retention
• Surface finish
• Processing stability

Celanese processing guidance also notes that additional back pressure may be useful when using masterbatches to improve melt homogeneity.

Why Choose Santoprene 6SD001A30 NAT?

The main reason to select Santoprene 6SD001A30 NAT is its combination of very low hardness and thermoplastic injection-molding capability.

The grade provides:

• 28 Shore A hardness
• 0.900 g/cm³ density
• 422% elongation
• 1.9 MPa tensile stress at break
• 0.7 MPa stress at 100% elongation
• 1.5 MPa stress at 300% elongation
• 10 kN/m tear strength
• 27% compression set at 70°C / 24 h
• Natural/colorable appearance
• Injection-molding processability
• Shear-dependent melt behavior

For customers requiring a very soft natural TPV for injection-molded seals, flexible interfaces or soft functional parts, Santoprene 6SD001A30 NAT is an important grade to evaluate.

Processing Guidelines for Santoprene 6SD001A30 NAT

The current grade-specific processing method is:

Injection Molding

Drying Conditions

Proper drying helps maintain consistent injection-molding performance.

Injection Molding Conditions

These are grade-specific conditions and are more useful than simply applying a generic Santoprene processing window.

Optimum Melt Temperature

For Santoprene 6SD001A30 NAT, the current optimum melt temperature is approximately:

185°C

with a narrow recommended grade-specific range of:

180–190°C

This is notably lower than many harder Santoprene grades.

The processor should therefore avoid simply copying settings from a harder TPV grade.

Mold Temperature

The recommended mold-temperature range is:

20–40°C

with approximately:

30°C optimum

Mold temperature can influence:

• Surface appearance
• Filling
• Part release
• Cooling time
• Dimensional stability
• Cycle time

For complex thin sections, the actual optimum may require machine trials.

Holding Pressure

Celanese recommends a holding pressure of approximately:

50–75% of actual injection pressure

Holding pressure helps control:

• Sink
• Packing
• Part dimensions
• Surface quality

Because the material is very soft, excessive packing should be avoided during process optimization.

Screw Speed

A relatively high screw speed of approximately:

100–200 rpm

is recommended.

Higher screw speed increases shear, which is important because Santoprene TPV is shear dependent.

Shear-Dependent Flow

Santoprene 6SD001A30 NAT has relatively high melt viscosity at low shear rates.

As shear rate increases:

apparent viscosity decreases.

This means improved flow can often be achieved by:

• Increasing screw speed
• Using appropriate gate dimensions
• Increasing local shear
• Optimizing runner geometry

rather than simply increasing melt temperature.

Celanese specifically notes that increasing temperature has comparatively little effect on TPV viscosity, while higher shear can have a much larger effect.

Gate Design

Smaller gates can increase shear rate and therefore reduce apparent melt viscosity.

This can improve filling of:

• Thin sections
• Small features
• Flexible lips
• Detailed molded parts

However, gate dimensions must still be large enough to avoid excessive pressure or shear heating.

Back Pressure

Back pressure is not always necessary.

Where required, Celanese recommends approximately:

0.3–0.7 MPa

This can help:

• Homogenize the melt
• Maintain consistent shot size
• Improve color dispersion

Higher back pressure may be useful when processing with color masterbatch.

General Santoprene Processing Window

Although the grade-specific injection window is 180–190°C, Celanese also identifies a broader general Santoprene TPV processing window of approximately:

175–230°C

For Santoprene 6SD001A30 NAT, the grade-specific 180–190°C window should take priority when setting initial injection-molding conditions.

Material Compatibility

Santoprene TPV is incompatible with:

• POM / Acetal
• PVC

Processing equipment should therefore be thoroughly purged when changing between these materials and Santoprene 6SD001A30 NAT.

Cross-contamination may negatively affect processing stability.

Storage

Santoprene 6SD001A30 NAT should be stored:

• Indoors
• In original packaging
• With bags unopened until required
• Away from direct sunlight
• Away from moisture
• Away from excessive heat

Opened material should be protected before reuse and dried according to processing requirements.
