The fat showed simple DSC crystallization and melting thermograms with one distinct peak The rambutan seed fat RSF consisted of 42 5% arachidic and 33 1% oleic acids Its crystallization behavior was more similar to CB than KSF displaying a two-step crystallization curve with SFC lower than that of KSF
The crystallization behavior of homogeneous and heterogeneous linear low‐density polyethylenes (LLDPE) was investigated by evaluating the characteristics of melting traces obtained by differential scanning calorimetry (DSC) Based on the isothermal experimental results the concept of the effective nucleation induction time is suggested In the initial crystallization stage the Avrami

Then the effects of the functionalized eggshell powder on the nonisothermal and isothermal crystallization behavior melting characteristics and polymorph structures were investigated From the nonisothermal crystallization experiments the incorporation of supported β-form nucleator greatly enhanced the crystallization temperature of iPP
2007/11/22Effects of the crystallization temperature on the crystal structure and its melting behavior of poly (l-lactic acid) (PLLA) have been investigated by means of wide-angle (WAXS) and small-angle (SAXS) X-ray scattering optical microscopy and differential scanning
2008/10/30The crystallization behavior and melting characteristics and the β-PP content of β-nucleated PP were investigated and compared with PP nucleated by calcium pimelate The results indicated that the crystallization temperature of PP is markedly increased by addition of supported β-nucleating agent

1999/12/1Consequently the blending of nylon 6 6 with another nylon is expected to influence its crystallization and melting behavior Furthermore if blending is done in the melt interchange reactions (transamidation) are likely to occur [7-11] which initially result in the formation of block copolymers
The addition of LCP accelerated the overall rate of crystallization and caused a depression in equilibrium melting temperature especially at low LCP content Lauritzen–Hoffman analysis showed that the addition of LCP caused a reduction in the fold surface energy and increased the regime II to III transition temperature

2002/7/1The melting behavior of PBISC could not be investigated because of the too low rate of crystallization which does not permit the formation of the crystalline phase in reasonable times As can be seen the DSC curves exhibit three endothermic peaks
In this study α-phase nucleating agent (NA) 1 3:2 4-bis(3 4-dimethylbenzylidene) sorbitol (DMDBS) β-phase rare earth NA (WBG) and their compound NAs were introduced into isotactic polypropylene (iPP) matrix respectively Crystallization kinetics and subsequent melting behavior of the nucleated iPPs were comparatively studied by differential scanning calorimetry (DSC) under both
cost Crystallization temperature and associated heat of crystallization are imporant ct haracteristics and are sometimes used to differentiate various resins in addition to melting temperature and heat of fusion Crystallization characteristics of polypropylene can
Samples were studied by DSC 200PC (NETZSCH) in a nitrogen atmosphere for the crystallization behavior and melting characteristics About 10 mg samples were heated from room temperature to 200 C at the rate of 10 C/min and held for 5 min to eliminate the
2016/11/18Partially hydrogenated oil (PHO) has no longer GRAS status However PHO is one of the important ingredients in bakery and confectionary industry and therefore the food industry is seeking for an alternative fat to replace PHO Waxes have shown promise to fulfill that demand because of its easy availability and cheap in price Waxes with high melting points ( 40 C) help in the

2012/10/20Obviously the crystallization behavior and melting characteristics of β-zeolite filled iPP composites are distinctly different from those of zeolite and calcified zeolite filled iPP composites The higher crystallization peak temperatures of β-zeolite filled iPP composites proved the stronger heterogeneous nucleation of β-zeolite than zeolite and calcified zeolite
Low melting crystals can be classified into two categories according to their melting behavior superheating and reorganization characteristics Low styrene content copolymers still exhibit some chain folded lamellar structure The shift of the low melting
The melting behavior non-isothermal crystallization spherulite morphology and thermal stability property of PHBV/OVS composites were also investigated The nucleation behaviors and crystallization rate of PHBV/OVS were significantly enhanced with the formation of cross-linked networks with different side-chains and cross-linking points

The crystallization exotherm and melting endotherm peaks of the TPVs were broad and they shifted towards lower temperatures as the cooling rate was increased The analysis of non-isothermal crystallization kinetics indicates that the crystallization of the PP in the TPVs is heterogeneous nucleation with two or three-dimensional growth during primary and secondary crystallization
