FARRPRENE EF85A offers excellent flexibility and durability for injection-molded products requiring soft-touch performance. Ideal for automotive, consumer, and sporting applications.
FARRPRENE EF85A is a premium styrenic block copolymer-based thermoplastic elastomer designed for performance-driven injection molding applications. This grade offers a unique blend of softness, mechanical strength, and process efficiency—ideal for products that require both tactile comfort and long-term durability. Engineered for versatility, FARRPRENE EF85A delivers consistent results in high-volume production while enhancing the performance of molded parts across a wide range of industries.
FARRPRENE EF85A is particularly effective in applications that demand a balance between user comfort and structural reliability. Its soft-touch finish, combined with excellent skin compatibility, makes it ideal for grips, wearable devices, and personal care products. Despite its elasticity, the material provides enough rigidity to retain its form and resist physical stress over time.
Thanks to its optimized rheological behavior, FARRPRENE EF85A offers superior flow in complex molds, reducing injection molding cycle times while maintaining dimensional precision. This feature is especially useful in high-volume manufacturing environments where mold complexity and part consistency are critical to productivity and cost-effectiveness.
Engineered to withstand real-world conditions, this material performs well under thermal cycling, UV exposure, and mechanical fatigue. It resists wear and maintains elasticity in both indoor and outdoor environments, making it suitable for automotive trim, outdoor equipment components, and industrial covers exposed to fluctuating conditions.
This grade demonstrates strong bonding with substrates like ABS, polycarbonate, and nylon in multi-material molding. This enables the creation of hybrid parts that integrate rigid and flexible sections seamlessly, enhancing both functional and ergonomic properties in consumer electronics, tools, and sporting goods.
This TPE formulation offers excellent color dispersion and compatibility with a wide range of masterbatches, enabling vibrant and uniform coloration across molded parts. Its inherent surface characteristics allow for a smooth, matte or glossy finish—reducing the need for secondary coatings or treatments. These features make it a strong candidate for applications where aesthetic quality and brand consistency are critical, such as consumer electronics, retail packaging, and lifestyle products
FARRPRENE EF85A is an excellent material choice for manufacturers seeking a soft-touch, yet resilient elastomer for molded parts. It excels in:
Consumer Products: From ergonomic grips to stylish handles, this grade enhances user experience with a comfortable, flexible feel.
Automotive Components: Offers vibration-damping and soft-touch surfaces for interior trims, knobs, and seals.
Household Appliances: Ideal for parts that require tactile comfort and resistance to everyday wear and tear.
Protective Caps and Gaskets: Ensures sealing integrity and flexibility in components subjected to frequent stress or movement.
Footwear & Sporting Goods: Delivers long-lasting resilience and comfort, making it suitable for soft soles, inserts, and performance gear.
Comfortable Flexibility
FARRPRENE EF85A delivers a Shore A hardness of 85, offering a pleasant soft-touch experience while remaining firm enough for structural integrity.
Lightweight and Efficient
With a specific gravity of 1.08 and bulk density of just 0.77 g/cm³, it helps reduce overall product weight—an essential feature for modern, lightweight product designs.
Exceptional Elasticity
Thanks to elongation at break values of over 2000% in the cross direction, FARRPRENE EF85A can endure significant deformation while maintaining its form—ideal for applications requiring stretchability and tear resistance.
Robust Mechanical Performance
With tensile strengths of 10.79 MPa (flow direction) and 13.05 MPa (cross direction), plus excellent flexural modulus and compression resistance, it provides the durability and structural performance expected of high-end TPEs.
Superior Impact Resistance
Its Izod impact strength of 28.84 KJ/m² gives it exceptional energy absorption properties, making it highly suitable for protective components and rugged applications.
Seamless Processability
FARRPRENE EF85A offers excellent melt flow characteristics (MFI: 4.28 g/10min at 230°C/2.16kg and 2.1 g/10min at 190°C/5kg), ensuring smooth, repeatable injection molding with minimal cycle time and reduced defects.
When compared to traditional rubber or other thermoplastics, FARRPRENE EF85A offers distinct advantages:
Versus Rubber: No vulcanization needed, shorter production cycles, and fully recyclable—making it more cost-effective and sustainable.
Versus Other TPEs: With its high Shore A hardness and superior elasticity, this grade provides a more balanced solution where both softness and mechanical strength are essential.
Versus Filled Compounds: Unlike heavily filled grades, FARRPRENE EF85A maintains flexibility and elasticity without excessive stiffness, preserving tactile comfort without compromising strength.
For applications requiring a filled TPE option, grades such as FARRPRENE IF85A may be better suited, offering higher density and tensile strength where needed. However, for users prioritizing flowability, comfort, and medium-range hardness in an extrusion-grade formulation, FARRPRENE EF85A is an optimal match.
This grade is a reliable solution for demanding production environments that require:
Efficient processing on standard equipment
Durable yet flexible components
Consistent quality across batches
Lightweight product designs
Recyclability and sustainability in material selection
FARRPRENE EF85A not only meets these criteria—it exceeds them. Whether you’re manufacturing consumer goods, automotive interiors, or performance footwear, this grade brings softness, strength, and process efficiency together in one superior material.
Let FARRPRENE EF85A power your next product innovation with the comfort users expect and the performance manufacturers trust.
