1 产品描述 versalis manufactures and sells different petrochemical products (polyethylene, elastomers, styrenics and chemicals). The company activities are based on proprietary technologies, competitive processes, spread and ef?cient commercial network. versalis supply high quality products, successful brands and greatly customized service to the market. Constant commitment concerning quality and sustainable development, complete the versalis'

picture. Product description versalis supply a range of ethylene vinyl acetate co polymers (EVA) under the trademark Green?ex?. These products are made by the high pressure polymerization process adding the comonomer (vinyl acetate C VA) into the main polymer chain based on ethylene monomer. The technology and the type of polymerization (radical) rend these copolymers a special modi?cation of common LDPE materials. The main properties of EVA copolymers are different from the typical one of common LDPE polymers and the difference grows according to the increase of VA content. The range extends from properties similar to LDPE to rubber-elastic like properties for high VA content EVA copolymers. versalis 制造并销售多种石化产品(包括聚乙烯、弹性体、苯 乙烯等化学品) .公司立足于专有技术、 具竞争力的工艺, 广泛、 高效的商业网络. versalis 为市场提供高质量的产品、成功的品牌和高度定制化 服务. 不断追求优质和可持续发展一直是 Versalis 的努力方向. versalis 通过 Green?ex? 商标供应一系列乙烯 - 醋酸乙烯酯共聚 物(EVA)产品. 这些产品均通过高压聚合生成,将共聚单体(醋酸乙烯酯, 即VA)加入到以乙烯单体为基础的聚合物主链中. 该技术结合自由基聚合通过使以上共聚物发生分裂,对普通 的低密度聚乙烯(LDPE)材料实现了特殊改性. EVA 共聚物的主要性能不同于典型的普通 LDPE 聚合物.VA 含量的增加会使这种差异变大.EVA 共聚物性能的变化幅度 较大,可与 LDPE 相似,而随着 VA 含量的增加 EVA 共聚物在 性能上却类似弹性橡胶.

2 供应形式(supplyform)与储存 物理性能 Supply form and storage Green?ex? is supplied as neutral granules with VA contents ranging from

5 up to 28% by wt. and with melt ratio (MFR) ranging from 0.3 up to

12 g/10'

. The average bulk density of the granules without slip agent is 0.530 C 0.550 g/cm3 and of those with slip agent up to 0.590 g/cm?. When stored outdoors, Green?ex? should be protected from direct sunlight, heat and moisture. Physical properties The data listed in this paper are average values determined on standard test specimens prepared from different kind of technologies (?lm, compression moulded sheet, etc..). Individual measurements may deviate from these average values, depending on the conditions under which the test specimens are prepared. The properties of EVA copolymers are largely determined by vinyl acetate content and melt ?ow ratio. Green?ex? 系列产品为中性粒剂,其中 VA 的重量比为 5%~28%, 熔体流动速率(MFR)范围为 0.3g/10 分钟 ~12g/10 分钟.不含光 滑剂 (slip agent) 颗粒平均体积密度为 0.530~0.550g/cm3,添加 光滑剂的颗粒平均体积密度为 0.590g/cm3.将Green?ex? 产品 存储于户外时,应避免其受阳光直射、高温和潮湿. ( 本句备选:本文件中所列数据取自不同技术条件(薄膜、模 压板等)下标准测试样本的平均值.) 由于各测试样本的准备 条件不同,个体测量值可能会偏离这些平均值.EVA 共聚物的 性能在很大程度上取决于醋酸乙烯酯含量和熔体流动速率.
