preparation example Construction

[0042] The preparation of the compounds according to the invention is uncomplicated. The compounds of the present invention can be produced in batch or continuous operation.

[0043] Compounding in a continuous process typically occurs in a single or twin screw extruder at a temperature raised enough to melt the polymer matrix, with additional ingredients added at the head of the extruder or downstream of the extruder. Extruder speeds can range from about 50 to about 500 revolutions per minute (rpm), and preferably from about 350 to about 450 rpm. Typically, the output of the extruder is pelletized for subsequent extrusion or molding into polymeric articles.

[0044] Mixing operations in a batch process are typically performed in a Banbury mixer capable of operating at a temperature sufficient to melt the polymer matrix for the addition of solid component additives. Mixing speeds ranged from 60-1000 revolutions per minute (rpm). Likewise, the output of the mixer is shredded...

Abstract

Flame retardant polybutylene succinate (PBS) compounds using a non-halogenated intumescent flame retardant system are disclosed.

Description

[0001] priority statement [0002] This application claims priority to US Provisional Patent Application Serial No. 62 / 096,012 (Attorney Docket No. 12014030), filed December 23, 2014, which is incorporated herein by reference. field of invention [0003] The present invention relates to highly flame retardant polybutylene succinate (PBS) compounds using non-halogenated ingredients for applications with stringent requirements for flammability, heat release, smoke and toxicity. Background of the invention [0004] Unlike wood, metal or glass, thermoplastic compounds will not rot, rust or shatter. Thus, the world has witnessed a revolution in materials science over the past 70 years, which stems from the combination of thermoplastic resins and one or more functional additives to provide special properties to the resins. [0005] Unlike wood, but similar to metal and glass, thermoplastic resins melt at a given temperature. Its processing versatility benefits from its ability t...
