KEY CHARACTERISTICS • Fabric FX can be formulated to include properties such as UV color protection and anti-scratch performance • Fabric FX can be processed on standard molding machinery • Different matrix materials can be enhanced with Fabric FX, including ABS, PC/ABS, PB, and unfilled or talc-filled PP • There is no limitation on the graining that can be used; the fabric effect will differ depending on the grain effect engraved in the tool • If parts are extruded or a mold is not engraved, final parts will have an attractive speckled appearance, but will not be textured TYPICAL USES Fabric FX concentrates are suitable for any application that could benefit from an enhanced textile-like appearance.

Extrudable and easy to process, these formulations are produced by crosslinking a polyethylene base resin and DBDPE-free catalyst using the Sioplas method, which offers significant advantages and economies over alternative crosslinking processes.

With the recognition, OnColor™ NIR Sortable Colorants are preferred for high-density polyethylene (HDPE) resin in black and dark colors, according to the APR Design® Guide for Plastics Recyclability. OnColor NIR Sortable Colorants from Avient provide a solution to this problem, allowing the packaging to be visible to a NIR optical sorter, enabling it to sort into the correct plastic stream. Avient is certified ACC Responsible Care®, a founding member of the Alliance to End Plastic Waste and certified Great Place to Work®.

Manufacturer improves durability, cost-effectiveness for plastic spinning tubes, bobbins Downtime, scheduled or not, is unwelcome – and it’s often due to a plastic part that costs less than a dollar. Istanbul-based IŞILSAN makes these plastic spinning tubes and bobbins, used on the world’s most advanced textile machinery to carry thread and spun yarn.

Typically, stiffer plastics are more brittle. This concept provides a competitive marketing advantage over products made from simpler plastics. In regard to plastics, the concept of design freedom incorporates several subtopics:
