Dutral BTX 9049 is a high-quality EPDM (ethylene-propylene-diene monomer) elastomer designed for industrial and automotive applications that demand excellent flexibility, resilience, and long-term durability.
This particular grade is part of the “BTX” family of Versalis Dutral elastomers, characterized by enhanced processability, making it suitable for high-loading formulations and sponge (foam) production.

Dutral BTX 9049 is supplied in friable bale form, allowing for easy incorporation into industrial mixers, which reduces compounding time and ensures uniform dispersion of fillers, oils, and additives.
Dutral BTX 9049 has a propylene content of approximately 39%, which contributes to its low-temperature flexibility, while the high diene (ENB or similar) content ensures fast vulcanization and robust crosslinking.

Its Mooney viscosity (~90 ML 1+4 at 125 °C) classifies Dutral BTX 9049 as a high-molecular-weight polymer, providing a good balance between elasticity and mechanical strength in finished compounds.
Recommended storage of Dutral BTX 9049 is in cool, dry, well-ventilated areas, with containers kept tightly closed.

Protective equipment such as gloves, goggles, and protective clothing should be worn when handling Dutral BTX 9049 in bulk, and proper industrial ventilation is advised during compounding or grinding operations.
Dutral BTX 9049 is generally stable, non-flammable, and compatible with standard EPDM compounding ingredients.

Dutral BTX 9049 is a high-molecular-weight EPDM (ethylene-propylene-diene) terpolymer, supplied as friable bales to facilitate processing.
Dutral BTX 9049 is an amorphous, non-volatile polymer that is solid at room temperature.
Dutral BTX 9049 has a propylene content of approximately 39 wt%, which contributes to its low-temperature flexibility, while the diene (ENB or similar) content ensures rapid vulcanization and effective crosslinking.

Dutral BTX 9049's Mooney viscosity is reported around ML (1+4) 125 °C ≈ 90, classifying it as a high-viscosity grade suitable for sponge and technical rubber applications.
Dutral BTX 9049’s density is typical for EPDM elastomers, approximately 0.86–0.88 g/cm³, and it is insoluble in water but may swell in some hydrocarbon oils.

Dutral BTX 9049 has a low glass transition temperature (Tg ≈ −50 to −55 °C), which allows excellent flexibility and elasticity at low temperatures.
The friable bale form increases surface area during compounding, promoting uniform mixing with fillers, oils, and other additives.

Dutral BTX 9049 has good thermal stability under typical processing conditions, although excessive heat may degrade the polymer or its antioxidant additive.
Dutral BTX 9049 is chemically stable, resistant to ozone and oxidation, and compatible with standard EPDM compounding ingredients.

In vulcanized form, DUTRAL BTX 9049 exhibits excellent resilience, compression set resistance, dimensional stability, and dynamic mechanical properties, which are essential for automotive sponge, seating, insulation, and other technical rubber applications.
Dutral BTX 9049 also demonstrates good filler loading capacity, allowing formulators to incorporate carbon black, processing oils, and other additives without compromising processability or finished part performance.

Dutral BTX 9049 is a commercial EP(D)M elastomer (ethylene-propylene-diene terpolymer) sold by Versalis (Eni) as an experimental/branched terpolymer grade designed for improved processing and sponge (foam) applications.

Dutral BTX 9049 is produced by suspension polymerisation with a Ziegler–Natta catalyst and during manufacture a non-staining antioxidant is added; the material is supplied in an “easy processing (EP)” friable bale form intended to make filler incorporation and mixing easier on industrial mixers.

Key formulation markers of Dutral BTX 9049 are a propylene content of about 39% by weight and a relatively high Mooney viscosity ML (1+4) at 125 °C ≈ 90, which places it among high-viscosity, high-molecular-weight EPDM elastomers tailored for sponge and heavy-duty parts.
Dutral BTX 9049 recommends storage in dry, ventilated areas below about 35 °C and states a typical shelf life of 36 months under proper storage.

From a physical-chemical perspective, Dutral BTX 9049 behaves like a typical EPDM terpolymer: it is essentially a non-volatile, amorphous rubbery solid at room temperature (supplied as bales) with bulk density and polymer properties that depend on batch and processing form.

USES and APPLICATIONS of DUTRAL BTX 9049:
In practical terms, Dutral BTX 9049 is widely used in automotive sponge applications, such as seats, cushions, and headrests, as well as technical rubber goods like extruded profiles, seals, and insulation materials.
Dutral BTX 9049's composition allows for high filler incorporation, meaning that compounding with carbon black, oils, or other reinforcing agents can be achieved without compromising the workability of the polymer.

The grade exhibits excellent dimensional stability, low-temperature performance, and rebound resilience, making Dutral BTX 9049 ideal for components exposed to repetitive mechanical stress.
Because of its high diene content, Dutral BTX 9049 is suitable for both sulfur and peroxide curing systems, giving formulators flexibility in choosing the curing method based on desired hardness, compression set, and dynamic properties.

From a chemical and physical perspective, DUTRAL BTX 9049 behaves as a non-volatile, amorphous solid at room temperature.
Dutral BTX 9049’s thermal and mechanical stability allows it to withstand typical processing temperatures without degradation, although standard precautions should be taken to avoid overheating during mixing, extrusion, or molding.

Dutral BTX 9049's friable bale form improves surface area contact during compounding, accelerating homogenization and ensuring consistent final properties.
Dutral BTX 9049 is insoluble in water but can swell in certain hydrocarbon oils, which is advantageous in oil-extended sponge compounds.

The benefits of using Dutral BTX 9049 include: easier processing due to improved dispersibility, high compatibility with fillers and oils, predictable vulcanization behavior, excellent low-temperature elasticity, long-term dimensional and mechanical stability, and enhanced dynamic performance for applications requiring repetitive load-bearing capacity.

These characteristics make Dutral BTX 9049 a preferred choice for automotive, furniture, and technical rubber manufacturers who require high-performance, reliable EPDM grades.
In terms of safety and handling, Dutral BTX 9049 is considered a low-hazard polymer under normal industrial conditions.

Dutral BTX 9049’s main advantages to compounders are easier filler and oil incorporation, improved mixing/workability, high loading capacity (so formulators can use more filler or oil while still maintaining compound performance), fast cure due to elevated diene content, good dimensional stability, and robust low-temperature elasticity.

These translate into finished parts that have lower density sponge (for cushion/seat applications), good compression–deflection behaviour, good resilience, and consistent extrusion/molding/vulcanisation performance.
Dutral BTX 9049 is recommended where automotive sponge performance, good collapse resistance and reliable mixing behaviour are priorities.

Dutral BTX 9049 is used in automotive sponge and some solid profile applications.
Main Applications of Dutral BTX 9049: Automotive, technical goods, building
The grade’s propylene content of Dutral BTX 9049= 39% (wt) and the Mooney viscosity value above, and shows it in EP bale form that absorbs more oil/additives during mixing than compact forms, enabling improved compound workability and potentially shorter mixing cycles.

Typical EPDM class values for density (~0.86–0.88 g·cm⁻3), low glass transition temperature (good low-temperature flexibility), and Mooney viscosity ranges are consistent with the Dutral family; the precise numbers for Dutral BTX 9049 (propylene content, Mooney) come from the manufacturer’s TDS.

The grade’s high ENB (ethylidene norbornene) or similar diene fraction provides sites for sulfur or peroxide vulcanisation and gives rapid cure behaviour and good dynamic properties in the vulcanised compound.

The grade is described as having high ENB (diene) content to ensure fast curing, high loading capacity (so it accepts fillers/oils well), easier dispersion during mixing, good dimensional stability and improved low-temperature elasticity — qualities that make Dutral BTX 9049 particularly suitable for automotive sponge (seats, cushions) and some solid profile/technical goods and building applications.
