福特混动车内饰采用可口可乐瓶材料技术

日前福特和可口可乐公司宣布，福特FusionEner西插电式混合动力车即将在洛杉矾车展亮相，该车内饰采用了可口可乐瓶身的植物基塑料材料。可口可乐从2（）f）9年开始应用部分使用植物性材料的PET瓶“PlantBottle”。PET（P0lvethvlcHeTerephthalate），即聚对苯二甲酸乙二醇酯，可以由植物原料制取。可口可乐瓶中的植物性材料比重最高可达30％。因而福特宣称成为首个采用植物基塑料的车企、     

汽车用PET工程塑料的研究现状与发展趋势

1 国内外车用PET工程塑料的发展概况 聚对苯二甲酸乙二醇酯(简称PET树脂)具有优良的机械性能,耐磨损、耐摩擦、抗蠕变性好、刚性和硬度大、吸水性低、尺寸稳定性高.缺点是结晶速率小,模塑温度高、热机械性能和冲击性能差.     

Biocompatibility evaluation of polyethylene terephthalate artificial ligament coating hydroxyapatite by fibroblasts cells in vitro

Hydroxyapatite (HA) based materials have been widely used in the field of ligament tissue engineering in the past decades. It has been previously reported that HA can increase the penetration of marrow-derived mesenchymal stem cells (MSCs) and MSCs cells into scaffolds due to increased cell differentiation in biological media. Additionally, it was found that there are much difference between MSCs and anterior cruciate ligament (ACL) cells. For that reason, we mainly evaluate the biocompatibility of polyethylene terephthalate (PET) silk scaffold with fibroblasts cells in vitro. We cultured mouse fibroblasts cells on the substrate of PET fiber and PET-HA scaffold, respectively, and then observed the morphology by using scanning electron microscopy. Our data indicate that PET-HA scaffold has good biocompatibility with fibroblasts cells and can potentially be useful in enhancing the fibroblasts cell differentiation and proliferation.     

立维腾选用SABIC Valox iQ树脂推出新型电动车充电器

沙伯基础创新塑料（SABIC）日前宣布，北美领先的电气设备与系统制造商立维腾制造有限公司决定选用ValoxiQ。树脂来制造其新款Evr—GreenTM电动车（EV）核心便携式充电器的外壳。ValoxiQ树脂由消费后聚对苯二甲酸乙二醇酯（PET）瓶升级回收后制成，可以进行模内着色，避免喷涂造成的二次染色，进而大大提升了立维腾充电器的环保性。     

Preparation and characterization of polysulfonamide statistical copolymers from three aromatic diamines

Various polysulfonamide(PSA) statistical copolymers were synthesized by polycondensation of three aromatic diamines and terephthaloyl chloride.The inherent viscosities of the resulting PSA copolymers range from 1.54 to 1.66 dL/g.The precipitated PSA copolymers with feed content of p-phenylene diamine(PPD) being less than 50%(mole fraction) can be redissolved in N-methyl-2-pryrrolidone(NMP) or N,N-dimethylacetamide(DMAc) with lithium chloride of wLiCl=0.02.All of the PSA copolymers exhibit enhanced tensile s...     

GE汽车塑料推出新品

美国GE公司塑料部门日前宣布，作为PBT（聚对苯二酸丁二酯）树脂Valox和PBT／PC（聚碳酸酯）聚合材料Xenoy的新系列，将上市85％使用废旧PET（聚对苯二甲酸乙二醇酯）塑料瓶的汽车工程塑料Valox iQ和Xenoy iQ。     

对苯二甲酰氯的纯度分析

１）用氯离子选择性电极测定活氯方法对对苯二甲酰氯进行了纯度分析,与熔点法,气相色谱法,示差扫描量热法（ＤＳＣ）比较对照,证明该法准确可靠,重复性好,简便,快速,易行;２）用ＤＳＣ考虑了高纯度对苯二甲酰氯的热行为,与文献（４）不同的是发现其在５９￣７０℃之间有２个小的吸热峰,通过热重分析（ＴＧＡ）,Ｘ－射线等确定了这２个峰为不可逆晶形转变峰,初步认为可作为纯度分析的依据。     

巴斯夫:加强特性材料本地化生产

日前,巴斯夫特性材料业务部三大重点扩建项目在上海浦东基地顺利展开,包括工程塑料Ultramid~()(聚酰胺,PA)、Ultradu~()(聚对苯二甲酸丁二醇酯,PBT)产能扩建、ElaStollan~()热塑性聚氨酯弹性体(TPU)产能扩建,以及CellaSto~()微孔聚氨酯弹性体)技术中心和产能扩建。     

沙伯基础创新塑料研制出“能量吸收器”

现代汽车曾与沙伯基础创新塑料（SABIC）就QarmaQ高级技术示范车型进行合作，并共同开发了其Elastic Front安全系统概念。前不久，现代汽车印度有限公司（HMIL）又选择了使用沙伯基础创新塑料的Xenoy。聚碳酸酯／聚对苯二甲酸丁二酯（PC／PBT）合金，通过设计和生产一种符合欧盟严格的关于行人下肢碰撞安全保护规定的能量吸收器（EA）以配备在现代i10（HMIL生产的一种用于出口的城市车）车型上。
