Description
PENTABROMOBENZYL ACRYLATE, also known as Pentabromobenzyl Acrylate (PMA), is a chemical compound that possesses flame retardant properties and is utilized as a standard for environmental testing and research. It is characterized by its high oxygen index (OI) value of 29.7, which indicates its effectiveness in reducing the flammability of materials.
Uses
Used in Flame Retardancy:
PENTABROMOBENZYL ACRYLATE is used as a flame retardant for enhancing the fire resistance of various materials. Its application reason is its high oxygen index value, which contributes to the reduced flammability of materials.
Used in Environmental Testing and Research:
PENTABROMOBENZYL ACRYLATE is used as a standard in environmental testing and research for evaluating the effectiveness of flame retardant materials and assessing their environmental impact.
Used in Polymer Industry:
PENTABROMOBENZYL ACRYLATE is used as a monomer for forming copolymers with styrene. The application reason is to create novel, flame retardant nano/micro-sized particles (0.06 ± 0.01 and 1.70 ± 0.23 μm) through polymerization in methyl ethyl ketone.
Used in Plastics and Polymers:
In the plastics and polymers industry, PENTABROMOBENZYL ACRYLATE is used for treating polyamide (PA6) to improve its flame retardancy. The application reason is the combination of PMA with montorillonite (OMMT) to enhance the fire resistance properties of PA6.
Check Digit Verification of cas no
The CAS Registry Mumber 59447-55-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,4,4 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 59447-55:
(7*5)+(6*9)+(5*4)+(4*4)+(3*7)+(2*5)+(1*5)=161
161 % 10 = 1
So 59447-55-1 is a valid CAS Registry Number.

Single-faced flame resistance of cotton fabrics modified via mist copolymerization
Yang, Zewen,Zhang, Yanyan,Fu, Feiya,Liu, Xiangdong
, p. 53871 - 53877 (2017/12/05)
Cotton fabrics with single-faced flame resistance are successfully fabricated through a simple mist copolymerization process using pentabromobenzyl acrylate (PBBA) as the functional monomer. The co-monomers are methyl acrylate (MA), which can react with the hydroxyl groups of cellulose by transesterification, and divinyl benzene (DVB), a cross-linker. SEM images indicate that a very thin copolymer layer (the thickness is about 200 nm) was formed on the cotton fiber surface and the flame resistance tests show that the modified fabrics have an improved flammability with longer time to ignition (TTI), lower peak heat release rate (PHRR), lower total heat release (THR), and lower average mass loss rate (AMLR), when compared to the original cotton fabric. The modification also results in good wearing durability because the flame-retardant coating was covalently linked to the cotton fabric surface by many ester groups. Moreover, desired cotton characteristics such as tensile strength, water absorbency, vapor permeability and flexibility are mostly retained because the mist method gives a single-faced modification of the cotton fabrics.
