Ects of diverse crosslink densities on the strain-induced crystallization (SIC) of vulcanized rubber and located that crystallinity created a lot more swiftly in samples with larger crosslink density, but was restricted in extent. Toki et al. [17] indicated that the crystallinity improved with strain. They recommended that stretched rubber could fall into three phases, namely a non-oriented amorphous phase, an oriented amorphous phase, along with a crystalline phase. SIC of unfilled and filled NR was also assessed by Poompradub et al. [18], who found that the onset strain of SIC decreased soon after adding filler. The degree of lattice deformation decreased with filler content material, in particular in carbon black (CB) filled composites. Chenal et al. [19] additional explained that distinctive fillers have various traits connected with the rubber iller interactions/reactions. This can either accelerate or slow down SIC based on chemical crosslink density inside the NR matrix. A related observation was reported in vulcanized NR containing CB particles by Candau et al. [20]. Determined by the reports above, rubber iller interactions may well speed up crystallization at a certain crosslink density. In this report, we present parallel wide angle X-ray scattering andPolymers 2021, 13,3 oftensile measurements of ENR composites filled with acid-treated HNT. To date, no report has been published with a detailed investigation regarding the connection between mechanical and dynamic properties along with the SIC of rubber composites. The usage of acidtreated HNT reinforced the ENR composites. The results explored within this study give an enhanced TG6-129 MedChemExpress scientific understanding of your function of acid-treated HNT in affecting the general properties of ENR/HNT composites, and can be useful for the manufacturing of rubber goods determined by ENR/HNT composites. 2. Experimental Facts 2.1. Supplies High ammonia centrifuged latex (HA) with 60 dry rubber content material (DRC) was applied to prepare ENR. This latex was centrifuged and supplied by Chalong Latex Market Co., Ltd., Songkhla, Thailand. The chemicals involved inside the synthesis of ENR were Teric N30 as non-ionic surfactant and formic acid and hydrogen peroxide for performic acid reaction, bought from Sigma Aldrich (Thailand) Co. Ltd., Vc-seco-DUBA manufacturer Bangkok, Thailand. The HNT were supplied by Imerys Ceramics Limited, Matauri Bay, New Zealand. The elemental composition of HNT was as follows: SiO2 (49.5 wt ), Al2 O3 (35.5 wt ), Fe2 O3 (0.29 wt ), TiO2 (0.09 wt ), too as traces of CaO, MgO, K2 O, and Na2 O. Sulfuric acid was supplied by RCI Labscan Ltd., Bangkok, Thailand. Stearic acid was bought from Imperial Industrial Chemicals (Thailand) Co., Ltd., Bangkok, Thailand. ZnO was supplied by Global Chemical Co., Ltd., Samut Prakan, Thailand. N-cyclohexyl-2-benzothiazole sulfenamide was provided by Flexsys America L.P., Akron, Ohio, USA, and soluble sulfur was purchased from Siam Chemical Market Co., Ltd., Samut Prakan, Thailand. 2.2. Preparation of Epoxidized Organic Rubber The synthesis of ENR was begun by diluting the latex to DRC 15 . Next, 1 phr of non-ionic stabilizer (10 Teric N30) was added even though stirring for 30 min at ambient temperature to expel the ammonia dissolved in the HA. The epoxidation was performed applying formic acid and hydrogen peroxide at 50 C within a 10-L glass container at a stirring price of 30 rpm. The total reaction time was fixed to receive ENR with 20 mol epoxide. The epoxide level was characterized as stated in our preceding report [8]. T.
