TECHNICAL REPORT: Antimony Pentoxide Synergists with Halogenated Flame Retardant Systems
TECHNICAL REPORT: Antimony Pentoxide Synergists with Halogenated Flame Retardant Systems

Antimony Pentoxide and Halogens form one of the most effective flame-retardant additive systems. Antimony pentoxide has several distinct advantages over trioxide in applications where a small particle synergist with a low index of refraction is desirable.

TECHNICAL REPORT: Colloidal Antimony Pentoxide in FR ABS By: Jeffrey Bartlett
TECHNICAL REPORT: Colloidal Antimony Pentoxide in FR ABS By: Jeffrey Bartlett

This paper will demonstrate the benefits of flame retarding ABS with the synergist BurnEx® ADP494 Colloidal Antimony Pentoxide. Most notably, higher izod impact strength and a minimal loss of translucency can be achieved. The advantages are a result of the differences in physical properties between antimony Sb2O5 and antimony trioxide Sb2O3.

TECHNICAL REPORT: Optimizing Halogen-Antimony Flame Retardants
TECHNICAL REPORT: Optimizing Halogen-Antimony Flame Retardants

Halogenated organic compounds used with antimony-based synergists are some of the most effective flame retardant systems known. In most cases, optimum flame retardant performance in a halogen-antimony system is attained when the halogen and antimony are used in a 3:1 mole ratio.

TECHNICAL REPORT: Typical Application Formulations for Textiles and Paper
TECHNICAL REPORT: Typical Application Formulations for Textiles and Paper

NYACOL® offers colloidal antimony pentoxide in a water dispersion of 0.03 micron particles. This document provides several starting formulations covering a wide range of applications. The type and amount of flame retardant used in textile and paper applications depends on many factors, including the fiber used in the substrate, construction of the fabric or web, application method, flammability standards to be met and durability requirements.

TECHNICAL REPORT: Yttria for Investment Casting
TECHNICAL REPORT: Yttria for Investment Casting

NYACOL® yttria sols are finding increasing use in investment casting shells as an yttria wash coat. Such a surface coating on the shell provides for a very low reactivity surface for the casting of titanium and the nickel and cobalt super alloys.

TECHNICAL REPORT: Zirconias for Investment Casting
TECHNICAL REPORT: Zirconias for Investment Casting

One of the principal uses of colloidal zirconia is as a binder for investment casting of reactive metals or the super alloys. The zirconia sols are used in the slurry formulations for the prime coatings and act as a binder for the refractory grains in the dried shell.
