Elvax® 40L-03Ethylene Vinyl Acetate CopolymerDuPont Packaging & Industrial Polymers产品说明：DuPont™ Elvax® 40L-03 is an ethylene-vinyl acetate copolymer resin for use in industrial applications.The melt index is consistent because resin molecular weight distribution is controlled to within a relatively narrow range. The molecular weight is high for this family of copolymers, so finished products will be relatively resistant to mechanical damage and elevated temperatures.Compared with other ethylene/vinyl acetate copolymers, Elvax® 40L-03 contains extremely low amounts of gel, or high-molecular-weight polymer, that can cause undesirable characteristics in finished products.Because Elvax® 40L-03 is somewhat crystalline, it is free flowing and does not mass during handling.UsesIndustrial Applications zWire & Cable ApplicationsWire JacketingComposition40 % By Weight Vinyl Acetate comonomer contentThermal Stabilizer: BHT antioxidantFeaturesHigh Molecular Weight, High ViscosityApplicationsElvax® resins can be used in a variety of applications involving molding, compounding, extrusion, adhesives, sealants, and wax blends. For additional information and properties associated with specific applications, please refer to the Grade Selector Guides found on the Elvax® website for industrial applications: http://www2.dupont.com/Elvax/en_US/tech_info/index.htmlElvax®40L-03 is especially well suited for use in jacketing compounds for automotive ignition and low-smoke cables, and as strippable semiconductive shields for power cables.In these applications, the relatively narrow molecular weight distribution and the low gel properties help ensure that compounds will be consistent and finished products will be smooth-surfaced. Smooth, glossy surfaces are desirable because they can imply quality, while uniformity can enhance long-term performance.Power cable semiconductive shields made with Elvax®40L-03 also benefit from the consistency of their compounds and low gel content. Any inconsistency in shields can lead to cable failure.物性信息：基本信息添加剂抗氧化性热稳定剂特性半结晶低速凝固晶点高分子量共聚物抗氧化性热稳定性食品接触的合规性优良外观窄分子量分布粘度，高用途电线电缆应用电线护套复合工业应用混合密封剂汽车领域的应用粘合剂机构评级FDA 21 CFR 177.1350 (d)形式粒子加工方法吹塑成型电线&线缆挤出成型复合挤出结构发泡成型泡沫处理片材挤出成型压缩模塑注射成型物理性能额定值单位制测试方法比重0.967g/cm³ASTM D792, ISO 1183熔流率（熔体流动速率） (190°C/2.16 kg)3.0g/10 minASTM D1238, ISO 1133醋酸乙烯含量40.0wt%热性能额定值单位制测试方法熔融峰值温度58.0°CASTM D3418, ISO 3146Freezing Point 1 --26°CISO 3146 --26°CASTM D3418注射额定值单位制加工（熔体）温度< 230°C挤出额定值单位制熔体温度< 230°C广州、番禺 顺德 江门 中山 珠海 深圳 惠州 汕头 汕尾 陆丰 福建 厦门 福州 东莞 浙江 黄岩 台州 杭州 温州 余姚 江苏/苏州/上海/常州/昆山/泰州/张家港/武进/小河/江阴/太仓/扬州/淮安/大丰/杭州/慈溪/宁波/余姚/浙江/温州/乐清/南通/镇江/南京/丹阳/无锡市/徐州市/常州市/苏州市/南通市/连云港市/淮安市/盐城长期供应代理各型号级别eva包装原料、eva农用薄膜料、eva注塑制品料、eva电缆材料、eva泡沫塑料、eva母料载体、eva共混增韧材料、eva阻尼隔音材料等方面。
