Jampilen HP552R is a polypropylene homopolymer (PP homopolymer) developed for the production of staple fibers, continuous filament (CF), and bulk continuous filament (BCF) yarns. Manufactured by Jam Polypropylene Company (Iran) and other leading producers, this grade combines high conductivity, excellent spinnability, and good mechanical properties, making it ideal for fiber extrusion at medium to high spinning speeds.

As a strong and rigid homopolymer polypropylene, HP552R provides high tensile strength, dimensional stability, and superior stiffness compared to copolymer grades. These properties make it particularly suitable for applications that require shape retention and strength, such as carpet yarns, industrial textiles, and woven fabrics.

However, due to its higher crystallinity, this homopolymer tends to be more brittle than polypropylene copolymers—especially at low temperatures (below 0°C)—where impact resistance is reduced. Despite this, HP552R maintains excellent processing stability and uniform fiber formation, even under demanding extrusion conditions.
