Several formulations have been investigated in order to obtain UL94-V2 rated PP at 3.2 mm thickness.The results have demonstrated that 20 wt% of FGD is the optimal amount to be used together with 15 wt% MC and 3 wt% SolDP to get UL94-V2 PP material. The flame retardancy action of MC and SolDP can be, indeed, further strengthen by the presence of FGD filler, which is essential to guarantee the good fire reaction obtained. The results have also shown that the control of the dripping phenomena is essential and therefore a suitable plasticizer, acting also as flame retardant, shall be used in this system. The content of the plasticizer shall be optimized since, from one side, it favours dripping but, on the other side, it tends to decrease the heat stability of the polymeric matrix when used at high content (>5%).

The efficiency of hybridization of flame retarded epoxy/flax-cotton composites was assessed by performing static tensile and flexural strength evaluation, supplemented by impact strength measurements of the composites. Moreover, thermal and thermomechanical analyses (DMA, DSC, and TGA) were performed. Epoxy composites were subjected to flammability using a PCFC microcalorimeter and cone calorimeter measurement to assess the burning behavior of composites. The introduction of the low-cost plate-shaped filler resulted in several favorable thermal effects while deteriorating the structure of the composite. The addition of small amounts of vermiculite (1–2 wt%) into the matrix modified with APP enabled the reduction of heat release rate (HRR) and total heat release (THR) by 60% and 20%, respectively.

They are ubiquitous and easily ignitable polymeric materials that require addition of flame retardants to comply with fire safety requirements for various applications. Flame retardant additives can be incorporated into polymer matrix as fillers or at the molecular level, implying use of reactive additives. The latter approach is less developed, but usually offers several advantages over adding flame-retardant fillers: lower additive loading used to achieve specific level of fire performance, no flame-retardant migration with time, lower corrosiveness, better polymer stability etc. Rendering polyamides intrinsically flame retardant is therefore highly desirable. In this review we survey progress in inherently flame-resistant polyamides done over the period from 2004 to 2020. The polymers are grouped according to their chemical structures: aliphatic, semiaromatic and aromatic polyamides, polyamidoimides and hybrid siloxane-polyamides. Their monomer preparation, synthesis details, thermal properties and fire performance are discussed. The minimal inclusion criterion for this review was reported fire-resistance performance: either V-1/V-0 rating achieved in UL-94 burning tests or experimental or calculated LOI above 23%.</div>","PeriodicalId":7186,"journal":{"name":"Advanced Industrial and Engineering Polymer Research","volume":"6 2","pages":"Pages 95-131"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48551892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

I21/I2 for samples of linear low density polyethylene (LLD) polymerized by a Ziegler-Natta catalyst (ZN-LLD) lie near I21/I2 = 25, whereas those for specimens of metallocene linear low density polyethylene (m-LLD) scatter close to I21/I2 = 18. The plot of I21/I2 vs I2 for LLD showed that I21/I2 is almost independent on molecular weight and short chain branching (SCB), but strongly dependent on molecular weight distribution (MWD). The broader MWD, the larger I21/I2. This rule basically holds for both low density polyethylene (LDPE) and high density polyethylene (HDPE). However, at a certain I2 around 6 a discontinuous jump of I21/I2 for HDPE samples exits, where I21/I2 for samples of I2 less than 6 lie near those of LDPE and I21/I2 for ones having I2 bigger than 6 disperse close to those of ZN-LLD. In addition, bimodal PE or PE with long chain branching has a bigger I21/I2 in some case. Further, the relationship between the viscosity and melt index was discussed, indicating that I21/I2 as well as MWD is characteristic of all types of PE.
