用于糊料应用的PVC Vinnolit® E 70 LF是一种由氯乙烯和5%醋酸乙烯组成的微粒、糊料制备共聚物,可产生低粘度的塑料溶胶,具有良好的储存稳定性(见图)。由于醋酸乙烯酯的含量,Vinnolit® E 70 LF可以很容易地在较低的凝胶温度下加工。加工应用:Vinnolit® E 70 LF可采用标准方法、溶解器或低速搅拌机将其转化成糊状物。但是,应避免在混合过程中过度加热糊料,因为醋酸乙烯含量可能导致粘度升高。基于Vinnolit® E 70 LF的糊剂可通过所有常规程序应用。Vinnolit® E 70 LF是一种低温胶凝、低粘度的糊状等级,推荐用于喷涂热敏性基础织物、层压糊状物、地毯衬垫以及汽车车身底部和接缝密封胶。这些应用还得益于高填充物负载能力以及对织物基织物和汽车金属表面的良好粘合。为了降低糊状物的粘度和延长保质期,Vinnolit® E 70 LF可与同聚合物延长树脂(如vinnolit ext/vinnolit c 65 v)混合。显著的性能是:显著降低胶凝温度、良好的织物粘合性和汽车金属板粘合性、更好的机械性能、更好的UBC胶泥耐磨性、优异的塑性溶胶的贮存稳定性 PVC for paste application ® Vinnolit E 70 LF is a fine-particle, paste- making copolymer of vinyl chloride and 5 % vinyl acetate yielding low viscosity plastisols with an excellent storage stability (see diagram). Due to its vinyl acetate content, Vinnolit E 70 LF can be easily processed at lower gelling temperatures. Processing and Application: Vinnolit E 70 LF may be converted into pastes by the standard methods, by dissolver or low- speed mixer. However, undue heating of the paste during mixing should be avoided since the vinyl acetate content may cause a rise in viscosity. Pastes based on Vinnolit E 70 LF can be applied by all the usual procedures. Vinnolit E 70 LF is a low temperature gelling, low-viscosity paste grade, recommended for coating heat-sensitive base fabrics, laminating pastes, carpet backings as well as automotive underbody and seam sealants. These applications also benefit from a high filler-loading capability as well as good adhesion to textile base fabrics and automotive metal surfaces. To lower paste viscosity and increase shelf life, Vinnolit E 70 LF may be blended with homopolymer extender resins such as Vinnolit EXT / Vinnolit C 65 V. Remarkable properties are: significant lower gelling temperatures good adhesion at textiles and automotive metal sheets better mechanical properties better abrasion resistance in UBC-mastics excellent storage stability of plastisols |

“禁废令”之后,废塑料进口根本根绝
2019-02-25 中国“禁废令”之后,废塑料进口这块基本杜绝了。但由于中国庞大的市场需求,很多企业还是要通过进口再生塑胶粒来满足国内的生产需求。关于再生塑胶粒进口清关的问题,近期有很多朋友问到再生塑胶粒进口清关费用的,有问从泰国、老挝门到门费用的,有问进口单证的,有问进口申报价格的,有问口岸对再生料监管动态的,也有问进口再生料怎样才能享受0关税优惠的。下面汇总了再生料塑胶粒进口的相关进口报关信息供大家参考。 由于中国禁废,很多国内的塑料企业纷纷转到越南、泰国、马来西亚、老挝等东南亚国家采购再 |
