Santoprene 6SD002A87 NAT TPV | Natural Injection Molding TPV

描述

Santoprene 6SD002A87 NAT is a natural thermoplastic vulcanizate from Celanese designed for flexible and semi-rigid elastomeric components manufactured using conventional thermoplastic processing equipment.

The grade belongs to the TPV / TPE-V material family.

Santoprene TPV combines a dynamically vulcanized elastomeric phase with a thermoplastic matrix. This structure allows the finished material to provide many rubber-like characteristics while still being processed using conventional thermoplastic manufacturing methods.

For product designers and molders, this can provide several practical advantages:

• Rubber-like flexibility
• Thermoplastic injection molding
• Complex molded geometry
• Shorter processing cycles than many thermoset elastomers
• No secondary vulcanization step during normal molding
• Natural coloration
• Custom color capability
• Controlled reuse of clean manufacturing scrap

The NAT designation identifies Santoprene 6SD002A87 NAT as a natural-colored material rather than a standard black formulation.

This can be especially useful for parts requiring:

• White
• Gray
• Beige
• Custom colors
• Color coding
• Appearance matching

Santoprene TPV is widely used across sealing, automotive, consumer, building and industrial applications where manufacturers require both elastomeric behavior and thermoplastic processing. Celanese positions Santoprene broadly around sealing performance, durability, chemical resistance, design flexibility and manufacturing efficiency.

Key Features of Santoprene 6SD002A87 NAT

Typical Applications for Santoprene 6SD002A87 NAT

Santoprene 6SD002A87 NAT can be considered for injection-molded applications requiring a natural, flexible TPV.

The exact suitability for any application should be based on the customer’s required mechanical properties, temperature range, chemical exposure and part geometry.

Natural / Colorable TPV

One of the most commercially useful features of Santoprene 6SD002A87 NAT is its Natural base color.

Natural TPV can be useful when the finished part needs to be:

• White
• Light gray
• Beige
• Blue
• Red
• Green
• Color matched to another component
• Color coded by function

This is particularly useful in consumer, automotive, industrial and building applications where black is not acceptable.

For best results, use a color concentrate compatible with TPV.

The final formulation should be evaluated for:

• Color dispersion
• Surface quality
• Flow
• Mechanical properties
• Shrinkage
• Thermal stability

TPV Material Structure

Santoprene 6SD002A87 NAT belongs to the thermoplastic vulcanizate family.

TPV materials differ from ordinary thermoplastic elastomers because the elastomeric phase is dynamically vulcanized during manufacture.

The finished compound combines:

Vulcanized elastomeric domains + thermoplastic continuous phase

This structure gives Santoprene materials characteristics associated with both rubber and thermoplastics.

Potential benefits include:

• Elastic response
• Flexibility
• Recovery after deformation
• Chemical resistance
• Heat resistance
• Thermoplastic melt processability

This balance is one reason Santoprene TPV is widely used for seals, flexible housings and molded engineering components.

Santoprene 6SD002A87 NAT can therefore be evaluated for selected applications such as:

• Molded seals
• Grommets
• Flexible interfaces
• Protective parts
• Interior functional parts
• Technical elastomer components

A specific OEM specification should only be claimed when confirmed by current grade-specific documentation.

Building & Construction Applications

Santoprene TPV also has broad use in building-material applications.

Potential applications for a natural molded TPV include:

• Flexible construction components
• Colored seals
• Molded gaskets
• Protective interfaces

Processing Guidelines for Santoprene 6SD002A87 NAT

The primary conversion method for the grade is Injection Molding.

Because complete current grade-specific temperature settings were not available in the publicly accessible material information reviewed, the webpage should avoid presenting a neighboring grade’s processing temperatures as though they belonged to 6SD002A87 NAT.

For initial processing development, the current Celanese TDS should be requested and used as the primary reference.

Pre-Drying

Santoprene TPV processing commonly uses controlled drying when required.

Important variables include:

Injection Molding Optimization

Important process variables include:

• Melt temperature
• Mold temperature
• Injection speed
• Injection pressure
• Holding pressure
• Screw speed
• Back pressure
• Gate dimensions
• Runner geometry
• Venting
• Cooling time

These parameters should be optimized together rather than independently.

Shear-Dependent TPV Flow

Santoprene TPV typically exhibits shear-thinning behavior.

As shear rate increases, apparent melt viscosity decreases.

This means flow can often be improved through:

• Appropriate screw speed
• Correct gate dimensions
• Higher injection speed
• Efficient runner design

rather than simply increasing melt temperature.

This can be especially useful when filling:

• Thin sections
• Small ribs
• Flexible lips
• Narrow flow paths
• Detailed part geometries

Gate Design

Gate design has a significant effect on TPV filling.

A suitable gate can provide:

• Sufficient shear
• Stable filling
• Consistent pressure
• Good surface quality

The ideal gate size depends on:

• Part thickness
• Flow length
• Material hardness
• Mold layout
• Injection-machine capability

Mold Venting

Proper venting is particularly important for flexible thermoplastic materials.

Poor venting may contribute to:

• Burn marks
• Short shots
• Poor surface appearance
• Excessive injection pressure

Vents should be positioned near the end of flow paths and other potential air traps.

Part Ejection

Flexible materials can behave differently from rigid thermoplastics during ejection.

The mold should provide:

• Adequate draft
• Suitable ejector area
• Smooth cavity surfaces
• Controlled cooling

This reduces the risk of:

• Part deformation
• Ejector marks
• Stretching
• Tearing during removal

Coloring Santoprene 6SD002A87 NAT

Because this grade is Natural, color masterbatch can be introduced according to the required appearance.

Important considerations include:

• Carrier compatibility
• Pigment concentration
• Dispersion
• UV requirements
• Heat stability
• Surface appearance

For applications requiring long-term outdoor exposure, pigments and additives should also be selected for the relevant UV and weathering environment.

Material Compatibility

Proper purging should be used when changing materials.

Santoprene processing guidance commonly requires particular care when transitioning from incompatible polymer systems.

Equipment cleanliness is important to prevent:

• Contamination
• Surface defects
• Unstable processing
• Color contamination

This is especially important when processing a Natural grade, because dark contamination is much more visible than in black TPV.

Storage

Santoprene 6SD002A87 NAT should be stored:

• Indoors
• In original packaging
• In dry conditions
• Away from excessive heat
• Away from direct sunlight
• With opened bags protected from contamination

Natural material should also be protected from dust and dark-colored contamination because these can become visible in the molded component.

Legacy Forprene Grade Name

Older material databases and technical references may identify a corresponding grade as:

Forprene 6SD002A87 NEUTRO

while newer databases index:

Santoprene 6SD002A87 NAT.

Including the legacy name once on the webpage can be useful for customers searching old:

• Drawings
• Material lists
• BOMs
• Mold specifications
• TDS references

A good SEO sentence is:

Santoprene 6SD002A87 NAT, formerly referenced in some material databases as Forprene 6SD002A87 NEUTRO, is a natural TPV grade supplied within the Celanese elastomer portfolio.
