Description

Polyolefin Fibers CAS NO 308070-21-5 are a specialized class of synthetic fibers derived from polymers like polyethylene and polypropylene, engineered for high-performance applications. These fibers are valued for their exceptional chemical resistance, low moisture absorption, and excellent mechanical properties, making them a superior choice for demanding industrial environments. They are essential for manufacturers in the geotextile, construction, filtration, and composite reinforcement sectors seeking durable and reliable material solutions.

Application

• Geotextiles and Civil Engineering: Used for soil stabilization, erosion control, and drainage layer reinforcement in road construction and landscaping projects.
• Filtration Media: Ideal for liquid and gas filtration systems in chemical processing, water treatment, and power generation due to excellent chemical and thermal resistance.
• Concrete and Cement Reinforcement: Added to concrete mixes to control plastic shrinkage cracking and improve impact resistance and durability.
• Composite Materials: Serves as a reinforcing agent in thermoplastic and thermoset composites for automotive parts, industrial components, and consumer goods.
• Protective Textiles and Nonwovens: Manufactured into protective clothing, industrial wipes, and covers that require resistance to chemicals, mildew, and rot.
• Asphalt Modification: Enhances the performance of asphalt pavements by improving stability, reducing rutting, and extending service life.
• Thermal and Acoustic Insulation: Used in insulation materials for buildings and industrial equipment, benefiting from low thermal conductivity.
• Specialty Papers and Packaging: Incorporated into high-strength papers and packaging materials for added tear resistance and durability.

Quality Control

Our Polyolefin Fibers are produced under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Key parameters such as fiber denier, tensile strength, length distribution, and chemical composition are rigorously tested. Certificates of Analysis (COA) documenting these specifications are available for every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperature (15-25°C). Keep away from direct heat sources and open flames. To maintain optimal fiber integrity and prevent contamination, store away from strong oxidizing agents.
