产品介绍 product description
为无色、无臭、无味而有光泽的、透明的珠状或粒状的固体。 Cable filling masterbatch is a thermoplastic resin , which is a colorless, odorless, odorless, shiny, transparent bead or granular solid. ～ 1.09,透明度88% ～ 92%,折射率1.59 ～ 1.60 。 The density is 1.04 to 1.09, the transparency is 88% to 92%, and the refractive index is 1.59 to 1.60 . 产生双折射,即所谓应力-光学效应。 Under the action of stress , birefringence occurs , which is the so-called stress - optical effect. ～ 180 ℃ , 热分解温度 Product melting temperature is 150 ～ 180 ℃ , thermal decomposition temperature
但在丙酮中只能溶胀。 It is soluble in aromatic hydrocarbons, chlorinated hydrocarbons, aliphatic ketones and esters , but can only swell in acetone. Resistant to the action of certain mineral oils, organic acids, alkalis, salts, lower alcohols and their aqueous solutions. 在潮湿环境中仍能保持其力学性能和尺寸稳定性。 Low water absorption , can still maintain its mechanical properties and dimensional stability in humid environments. Optical performance is second only to acrylic resin. 体积电阻率和表面电阻率都很高,且不受温度、湿度变化的影响,也不受电晕放电的影响。 It has excellent electrical properties, high volume resistivity and surface resistivity , and is not affected by changes in temperature and humidity , or by corona discharge. Radiation resistance is also good. 耐热性较差,不能耐沸水,只能在较低温度和较低负荷下使用。 Its main disadvantages are brittleness and fragility, low impact strength , poor heat resistance , resistance to boiling water , and use at lower temperatures and loads. 易燃。 Poor sunlight resistance and flammable. 且有特殊臭味。 It emits black smoke when burning and has a special odor.
是以苯乙烯为单体经过自由基聚合或离子型聚合制得的。 The cable filling masterbatch is prepared by using styrene as a monomer through radical polymerization or ionic polymerization. Production methods include bulk polymerization, solution polymerization, suspension polymerization, and emulsion polymerization. At present, industrial polymerization mainly uses suspension polymerization and bulk polymerization.
适用范围 Scope of application
加工性能好,易着色,尺寸稳定性好。 Cable filling masterbatch has good fluidity, good processing performance , easy coloring , and good dimensional stability. 特别适用于注射成型。 It can be processed into various parts by injection molding, extrusion, blow molding, foaming, thermoforming, bonding, coating, welding, machining, printing and other methods , and is especially suitable for injection molding.
Materials for injection molding can generally be used without drying. 可以55 ～ 70 ℃ 鼓风烘箱内预干燥1 ～ 2h 。 However, in order to improve the quality of the product , it can be pre-dried in a blast oven at 55 to 70 ℃ for 1 to 2 hours . The specific processing conditions are roughly: barrel temperature
一般采用的螺杆长径比L/D为17 ～ 24,以空气冷却,挤塑温度150 ～ 200 ℃ 。 During extrusion molding , the L / D ratio of the screw generally used is 17 to 24, which is cooled by air , and the extrusion temperature is 150 to 200 ° C.
可采用注塑和挤塑制得的型坯进行吹塑制得所需制品。 When blow molding , the parisons obtained by injection molding and extrusion can be used for blow molding to obtain the required products. ～ 0.3MPa Blow molding pressure is generally 0.1 ～ 0.3MPa
产品用途 Product Usage
特别是良好的卫生性、价廉,使其在食品包装方面具有广阔的应用前景。 Because the cable filling masterbatch has excellent rigidity, electrical properties and printing properties , especially good sanitation and low price , it has a broad application prospect in food packaging. In the mechanical and electrical industry, instrumentation, communication equipment industry, etc., it has been widely used in various instrument housings, lampshades, optical parts, instrument parts, transparent window mirrors, transparent models, chemical acid storage tanks, acid transportation tanks, telecommunication parts, high frequency Capacitors, high-frequency insulation gaskets, brackets, inserts, and frozen insulation materials. 如瓶盖、容器、装饰品、纽扣、梳子、牙刷、肥皂盒、香烟盒及玩具等。 It is also widely used in various daily necessities , such as bottle caps, containers, decorations, buttons, combs, toothbrushes, soap boxes, cigarette boxes and toys.
产品包装和储存 Product packaging and storage
外包装采用防潮纸塑复合包装，内用塑料包装袋，净重 The outer packing of the cable filling masterbatch is moisture-proof paper-plastic composite packaging, and the inner is a plastic packaging bag.
