PEBAX 70R53

Arkema, as a world-renowned brand, has always been known for the high quality of its products. The Pebax Rnew 63R53 SP 01 model recommended this time represents a breakthrough and innovation on this foundation. Below, we will provide a detailed introduction to this product from multiple perspectives.

PEBAX® 63R53 Comprehensive Introduction

1. Chemical Structure and Environmental Characteristics

1. Bio-based Material

   • Part of Arkema's RNEW® series, it uses renewable castor oil-based polyamide (PA11), with a bio-based carbon content of 77%-81%, reducing CO2 emissions by 68% and non-renewable resource consumption by 71%;
   • Compared to traditional petroleum-based PA12, it combines environmental friendliness with high-performance engineering plastic properties, complying with EU REACH, RoHS, and other standards.

2. Molecular Design

   • Composed of rigid polyamide (PA) and flexible polyether block copolymers, forming dynamic breathable channels that combine elasticity and mechanical strength;
   • Density range: 1.03–1.13 g/cm³, Shore D hardness: 61, with significant lightweight characteristics (20–30% lighter than traditional TPU).

2. Physical and Mechanical Properties

1. Weather Resistance and Stability

   • Short-term temperature resistance up to 270°C, long-term temperature range from -40°C to 170°C, enhanced outdoor durability with UV stabilizers, and excellent anti-aging performance;
   • Outstanding tear resistance and chemical corrosion resistance (to oils, weak acids, and bases), suitable for complex environments.

2. Processing Characteristics

   • High fluidity supports complex mold injection (e.g., hollow designs in sports shoe midsoles), recommended melt temperature: 225–260°C, molding temperature: 25–60°C;
   • Low moisture absorption, drying conditions: pre-drying at 65–75°C for 4–8 hours (only required after opening the packaging).

3. Typical Application Areas

1. Sports and Outdoor Equipment

   • Ski Boots/Sports Shoes: Lightweight and high rebound elasticity optimize cushioning performance, with low-temperature resistance suitable for extreme environments;
   • Eyewear Frames/Protective Components: UV resistance and wear resistance extend service life.

4. Precautions

• Model Differentiation: The suffix "SP01" indicates an industrial-grade heat/UV-resistant version, which should be distinguished from medical-grade or food-grade materials;
• Color Matching and Storage: The off-white base material requires verification of dye compatibility to avoid color discrepancies; unopened raw materials should be stored sealed and moisture-proof.

PEBAX® 63R53, through the combination of bio-based and high-performance properties, has become an innovative material solution for sports equipment, industrial protection, and medical fields.
