Product Overview

RQT® Nylon Heat Stabilizer S-EED is a unique multi-functional additive, an advanced versatile stabilizer for polymerized and compounded polyamides. This additive achieves high compatibility with nylon through molecular recognition. It delivers outstanding processing stability at high processing temperatures and reduces filament breakage during spinning. It improves production efficiency and shortens cycle times in injection molding, while providing long-term thermal stability, UV/light stability and favorable mechanical properties. In addition, it deepens the color shade of dyed and pigmented articles and offers high resistance to specific treatments such as hot water, cold water and chlorinated water.

Features and Advantages

◉ Dust-free form for easier and safer handling by operators ◉ Food-contact certified, suitable for packaging film applications ◉ Enables weight reduction of vehicles when polyamides are adopted in automotive applications ◉ PA nylon products incorporated with S-EED are recyclable ◉ Shorter molding cycles via processing at lower temperatures and shorter durations, boosting productivity and saving energy ◉ Reduced filament breakage during high-speed spinning to minimize waste ◉ Lower volatility compared with alternative products, resulting in reduced emissions during processing ◉ Broad applicability (usable for all types of polyamides), ideal for production and modification of PA6 and PA6,6 ◉ Improved processability / spinning performance, homogeneous and deep dyeability, deepening coloration for dyed and pigmented articles ◉ Maintains excellent processing stability even at very high processing temperatures ◉ Sustains good long-term thermal stability and UV/light stability ◉ High resistance to selected treatments, hot/cold water, chlorinated water, etc. ◉ Good mechanical properties

Applications of Nylon Stabilizer

◉ S-EED stabilizer provides excellent stability for filled and unfilled polyamides during processing and service life. It enhances color affinity and dispersibility of pre-metallized dyes, acid dyes and pigments to achieve economical, eco-friendly and deep coloration. ◉ The multi-functional S-EED stabilizer can be effectively combined with UV absorbers to further improve color retention and UV stability of polyamides. ◉ S-EED nylon stabilizer can be incorporated in-situ during polymerization or added as a concentrate during polyamide compounding.
