saudi basic industries corporation (Sabic), has launched a new set of resins of polypropylene (PP) for non-woven fabric applications (spunbond). Together, these high-performance materials, suitable for contact with food, offer the entire spectrum of customer needs, constant quality, saving energy and costs, a reliable supply and a contribution to sustainability. Sabic PP 511A as Sabic PP 519A, can be used in various applications: from products for the hygiene, roofs and covers, construction, to products for the automotive industry.

"Launch by Sabic of these grades 'fabric' help our clients achieve their goals by providing them with a wide margin of processability," says André Kamycki, marketing engineer and technician of PP of Sabic.

"Our strong logistics network guarantees the availability of these materials throughout Europe, Middle East, North Africa and Asia." We are currently the only provider that offers two degrees that can be combined in a single package for manufacturers of materials not woven into these areas. "In the same way, as new grades meet a wide variety of needs and applications of the client, Sabic can act as a global supplier for materials of polypropylene homopolymer resins used for the production of fiber".

The two new degrees of Sabic are made to measure (with a very narrow molecular weight distribution and an optimized package of additives), and therefore achieve maximum performance with the "spunbond" machinery of latest technology, together with excellent uniformity in the thickness of the fiber, resulting in a significant reduction in incidences of filament breakagean optical appearance of the excellent tissue, softness, and very good mechanical properties.

"Spunbond" producers may choose between Sabic PP 511A or Sabic PP 519A to optimize two different market sectors.

SABIC PP 511A is designed for a wide range of applications, from hygiene products to technical applications such as covers and mats for automotive and insulation moisture resistant coverings and roofs.

Also offers a balance between the high processing speed and uniformity of the thickness of the fibres, and significantly reduces breakage of fibres, which is reflected in a smaller number of defects of yarn in a less creation of suction filters and excellent optical properties of the retrieved tissue deposits.

Thanks to the optimisation of the used additives may reduce the frequency of cleaning of machines due to a slower than deposits in head formation. PP511A improves performance on machines of last generation, maintaining the desired mechanical benefits.

SABIC PP 519A is excellent for slim yarn of continuous filaments at high processing speeds. It produces tissues without weaving light and very soft, perfect for diapers and feminine hygiene products. An important aspect is that this resin has optimized rheological properties, so it can be processed at a temperature between 10 ° and 15 ° degrees lower than the temperature used for other conventional materials. As a result, can be found significant energy and cost savings that Sabic PP 519A makes an excellent choice for sustainable manufacturing.
