FARRPRENE IU45A

FARRPRENE IU45A is a lightweight, flexible TPE ideal for soft-touch injection-molded parts with high elasticity and durable strength.
Perfect for automotive, sports, and consumer applications where comfort meets performance.

FARRPRENE IU45A is a Styrenic Block Copolymer-based Thermoplastic Elastomer (TPE) developed to deliver exceptional balance between tactile softness and structural reliability. Specially formulated for injection molding processes, this grade ensures smooth processing, lightweight design, and impressive elasticity—making it ideal for a wide range of modern applications across consumer goods, automotive interiors, and sports equipment.

The formulation of FARRPRENE IU45A provides a well-controlled Shore A hardness, making it adaptable for applications that require a specific balance between softness and structural support. This tunability allows product designers to select the exact tactile response needed for various consumer-facing components.

Its low specific gravity is another advantage, enabling manufacturers to reduce overall part weight without sacrificing durability. This is especially beneficial in sectors like automotive, where lightweighting directly contributes to fuel efficiency and performance optimization.

FARRPRENE IU45A also demonstrates excellent process stability during injection molding, with minimal shrinkage and high reproducibility. These processing characteristics are critical for large-scale production where consistent quality across multiple batches is required.

Furthermore, this grade complies with key regulatory and environmental standards, including RoHS and REACH, which makes it a reliable choice for companies aiming to meet international compliance criteria while delivering high-performance end products.

In addition to its core benefits, FARRPRENE IU45A exhibits low odor emission during processing, an important factor for interior applications, especially in automotive and consumer environments where user comfort is a priority. Its inherent chemical resistance also ensures long-term durability when exposed to household cleaners, skin oils, and environmental stressors. This resistance broadens its usability in hygiene-related products, wearables, and personal care items. When paired with color masterbatches, the material supports vibrant pigmentation without compromising mechanical integrity, enabling greater design freedom across a variety of end-use sectors.

FARRPRENE IU45A also offers recyclability advantages, contributing to sustainable manufacturing goals. Its versatility supports multi-industry innovation and long-term performance.

FARRPRENE IU45A excels in projects where user comfort meets engineering strength. It is an ideal solution for:

  • Ergonomic Consumer Products: Flexible handles, grips, and housings benefit from its soft-touch feel and elasticity.

  • Automotive Interior Components: Perfect for soft-touch dashboards, control knobs, or trim parts that require both resilience and comfort.

  • Household Appliances: Used in buttons, seals, and pads that require a soft yet durable material.

  • Sports & Footwear Applications: Excellent for shoe components, protective sports gear, or any part that demands comfort with stretch.

  • Sealing Solutions: Gaskets and caps benefit from IU45A’s flexible sealing properties and resistance to tearing.

Whether you’re designing consumer electronics or automotive parts, this material ensures products feel good to the touch, look premium, and hold up under repeated use.

  • Soft Comfort, Strong Build
    With a Shore A hardness of 45, FARRPRENE IU45A delivers a soft, flexible feel while resisting deformation, wear, and tear.
  • High Elasticity and Recovery
    The material exhibits extraordinary elongation at break—over 2100% in cross direction—enabling extreme stretching and repeated recovery without cracking or failure.

  • Lightweight Advantage
    Its low specific gravity (0.88) and bulk density (0.6) allow for the creation of lighter parts without compromising strength or integrity.

  • Easy and Efficient Processing
    With excellent melt flow behavior (MFI 2.12 at 230°C), FARRPRENE IU45A is tailored for high-throughput manufacturing. It flows effortlessly into molds, ensuring minimal cycle time and consistent part quality.

  • Mechanical Reliability
    Its tensile strength (up to 4.49 MPa) and impact resistance (6.52 KJ/m²) make it suitable for demanding functional components where mechanical load or shock absorption is critical.

Performance Comparisons

Compared to conventional rubber or lower-grade elastomers, FARRPRENE IU45A offers superior processing ease, greater recyclability, and more consistent quality from batch to batch. Unlike vulcanized rubber, it requires no curing process, reducing time and cost in production. Additionally, its lower density translates to material savings and enhanced design flexibility, especially in weight-sensitive industries like automotive or sportswear.

When compared to other TPE grades in the FARRPRENE family, IU45A sits in the mid-soft range, balancing elasticity and mechanical integrity. For applications requiring more rigidity, IF65A or IF85A might be preferable. For extremely soft-touch requirements, FARRPRENE 20A offers even greater flexibility, though with less mechanical strength.

Sustainability and Manufacturing Benefits

FARRPRENE IU45A is fully recyclable and supports sustainable manufacturing practices by minimizing production waste and enabling regrind use. Its consistent flow behavior helps avoid process variability, while its compatibility with standard injection molding systems eliminates the need for specialized tooling or processing changes.
