Mica and talc substitute

Mica substitute is a liquid elastomeric water coating that forms a non-blocking film over the insulation. It replaces dry powders such as mica and talc that are dusted on surfaces to prevent blocking. Powders are classified as dust nuisances and can also cause accidents when spilled on the floor. Mica and talc substitute are in compliance with a number of directives. anti-blocking product, a soap solution that causes blistering, mica substitute will not behave in the same manner. It is a turn film former that encapsulates the insulation and will prevent sticking inside the jacket, the CV line or other areas of blocking concern. Various insulations that it has been used on include PVC to PVC, hypalon, crosslink, TPR and CPE. It is also used as a bond separator between hypalon and XLPE in the mould during the baking cycle. Mica substitute must form a film before reaching the rake up reel. Surface temperature should reach 212ºF to Unlike a competitive

New family of TufFill compounds

S&E Specialty Polymers LLC, a producer of speciality plastic compounds, has introduced a new family of TufFill™ non-halogen TPO compounds primarily designed for use in the wire and cable market. The new polyolefin based TufFill™ NH GTPO 8291 IT family features a wide range of unique properties including: • Intumescent flame retardant – low-smoke zero-halogen material • Highly flexible, durometer of 82 Shore “A” to 60 Shore “D” • Temperature rated to 105°C • 28-47 Limiting Oxygen Index (LOI) • Specific gravity of 0.94 – 1.08 for higher yields

• Good thermostability • Low water absorption

S&E’s choice of new generation metallocene polymers as the backbone of these materials allows easy control of flexibility without sacrificing FR and physical properties. An intumescent FR additive allows for a wide range of LOIs for meeting stringent UL requirements. “Our customers have asked us for a softer/more flexible low-smoke zero-halogen with a 40+ Oxygen Index for specific applications and we’ve delivered,” said Duane Shooltz, president and COO of S&E. “These compounds represent a higher-end offering from S&E that will provide users with significant benefits.” S&E Specialty Polymers – USA Website : www.sespoly.com ▲ ▲ The burn test on the new TufFill™ NH GTPO 8291
