CAS: 68259-31-4
Maceal (CAS: 68259-31-4) refers to a polyether block amide (PEBAX) thermoplastic elastomer. These high-performance copolymers are characterized by a unique block structure combining rigid polyamide (PA) blocks with flexible polyether (PE) blocks. This structure imparts a blend of properties including high flexibility, elasticity, low density, good impact resistance, excellent dynamic fatigue resistance, and a broad service temperature range, making it a versatile material for demanding applications.
Maceal (PEBAX) materials are utilized in various industries where flexibility, elasticity, durability, and chemical resistance are critical. Key use areas include sports equipment, medical devices, automotive components, and industrial applications. Their ability to maintain properties across a wide temperature range makes them suitable for demanding environments.
Specific applications for Maceal (PEBAX) include:
- **Sports & Leisure**: Ski boot shells, athletic shoe soles and components, protective gear, racket grommets.
- **Medical Devices**: Catheters (e.g., angioplasty, neurovascular), medical tubing, balloons for interventional procedures, surgical instrument components, drug delivery systems.
- **Automotive**: Airbag covers, air ducts, constant velocity joint (CVJ) boots, wire and cable jacketing.
- **Industrial**: Hoses, seals, gaskets, films, diaphragms, power transmission belts.
- **Electronics**: Cable insulation and jacketing for data and communication cables, flexible electronic components.
Maceal, as a polyether block amide polymer, is generally considered safe for many applications, including those requiring biocompatibility, provided specific grades meet regulatory standards. In its solid form, it is largely inert and non-hazardous under normal handling conditions. During processing (e.g., melting, extrusion), elevated temperatures can release minor amounts of volatile organic compounds or degradation products, which should be managed with adequate ventilation. Direct contact with molten polymer can cause severe thermal burns. Dust generated from mechanical processing may cause respiratory irritation. Always refer to the specific Safety Data Sheet (SDS) for the particular grade for detailed information on safe handling, storage, and emergency procedures.
