超高分子量功能化硅氧烷聚合物分散在高流动聚丙烯均聚物中。道康宁MB50-321母粒是一种含有50%功能化超高分子量（UHMW）硅氧烷聚合物的造粒配方。它被设计成在树脂相容系统中用作添加剂，以改善加工和改变表面特性。硅基塑料添加剂已在塑料工业中应用多年，以改善热塑性塑料的模具释放和流动性。它们在这方面是有效的，尽管迄今为止在不使用专用设备将低粘度液体准确地并入热塑性塑料熔体中遇到了一些困难。道康宁MB系列母粒通过提供高浓度超高分子量（UHMW）硅氧烷作为各种热塑性塑料中干颗粒形式的分散体来解决这些问题。硅氧烷以平均粒径小于5微米的分散相或不连续相在热塑性基体中精细分散。优点Dow Corning MB50-321 Masterbatch提供专利表面分离功能，有助于更高浓度的硅氧烷朝向制造零件的表面，从而提高表面效益。与迁移的低分子量流体不同，硅氧烷仅在热塑性塑料处于熔融相时才移动到表面，而在固化热塑性塑料中则停留在离散域中。表面改性需要较低水平的添加剂，因为更多的添加剂用于表面，而不是被困在内部。与标准聚二甲基硅氧烷（PDMS）相比，功能化硅氧烷具有独特的优势。超高分子量硅氧烷在聚烯烃薄膜中表现出优异的滑动性能，由于官能团对金属表面具有吸引力，聚合物加工过程中金属断裂减少。由于摩擦系数（cof）的稳定性，可以立即进行滑动测量。此外，COF在高速生产线和热包装应用过程中保持一致，这些应用在成型填充密封设备上产生高薄膜表面温度。当添加到0.2-2%硅氧烷的树脂兼容系统中时，该产品可减少熔体断裂、更好的模具填充、更低的挤出机扭矩、内部模具润滑、模具释放和减少模件的翘曲。在较高的硅氧烷负载水平下，2-10%的硅氧烷有望提高表面性能，包括提高润滑性和滑动性、降低摩擦系数和提高抗损伤能力。如何使用道康宁MB50-321母粒可以在与它所基于的热塑性塑料相同的条件下进行加工。应将足够的道康宁MB50-321母粒与原始聚合物颗粒混合，以在最终产品中提供所需的硅氧烷含量。道康宁MB50-321母粒可在挤出机中混合或在注塑、型材/片材挤出或其他常规热塑性工艺中在进料漏斗处干混。 Ultra-high molecular weight functionalized siloxane polymer dispersed in high flow polypropylene homopolymer. DOW CORNING MB50-321 Masterbatch is a pelletized formulation containing 50% of a functionalized ultra-high molecular weight (UHMW) siloxane polymer. It is designed to be used as additive in resin compatible systems to improve processing and modify surface characteristics. Silicone-based plastic additives have been used in the plastics industry for several years to improve the mold release and flow of thermoplastics. They are effective in this role, although until now some difficulties have been experienced in the accurate incorporation of low-viscosity liquids into thermoplastic melts without use of specialized equipment. The DOW CORNING® MB Series Masterbatches address these problems by supplying a high concentration of an ultra-high molecular weight (UHMW) siloxane as a dispersion in a dry pellet form in a variety of thermoplastics. The siloxane is finely dispersed in the thermoplastic matrix as the discrete or discontinuous phase at an average particle size of less than 5 microns. BENEFITS DOW CORNING MB50-321 Masterbatch offers a patented surface segregation functionality that facilitates a higher concentration of the siloxane toward the surface of a fabricated part, thus providing improved surface benefits. Siloxane moves to the surface only when the thermoplastic is in the melt phase, remaining in discrete domains in solidified thermoplastic, unlike low molecular weight fluids that migrate. Lower levels of additive are required for surface modification because more is utilized at the surface, rather than being trapped internally. The functionalized siloxane has unique advantages over standard polydimethylsiloxane (PDMS). The UHMW siloxane demonstrates superior slip performance in polyolefin films and, because the functional groups provide attraction to the metal surface, metal fracture is reduced during polymer processing. Because of the coefficient of friction (COF) stability, immediate slip measurement is possible. Moreover, the COF remains consistent at high line speeds and during hot packaging applications that generate high film surface temperatures on form-fill-seal equipment. When added to resin compatible systems at 0.2-2% siloxane, this product offers reduced melt fracture, better mold filling, lower extruder torque, internal mold lubrication, mold release and reduced warpage of the molded part. At higher siloxane loading levels, 2-10% siloxane, enhanced surface properties are expected, including enhanced lubricity and slip, lower coefficient of friction and improved mar resistance. HOW TO USE DOW CORNING MB50-321 Masterbatch may be processed at the same conditions as the thermoplastics on which it is based. Sufficient DOW CORNING MB50-321 Masterbatch should be blended with virgin polymer pellets to give the desired siloxane level in the final product. DOW CORNING MB50-321 Masterbatch can be added during compounding in an extruder or dry blended at the feed hopper during injection molding, profile/sheet extrusion or other conventional thermoplastic processes. |
超高分子量硅氧烷聚合物。道康宁MB50-001母粒是一种含有50%分散在聚丙烯（PP）均聚物中的超高分子量硅氧烷聚合物的造粒配方。它被设计成在聚丙烯兼容系统中用作添加剂，以提供诸如加工改进和表面特性修改等好处。液态硅氧烷塑料添加剂已用于改善热塑性塑料的润滑性和流动性。虽然在不使用专用设备的情况下，将液体加入热塑性熔体中遇到了一些困难，但它们在这方面是有效的。由于加工困难和出血问题，生产含20%以上液态硅氧烷的母粒也很困难。道康宁MB系列母粒通过提供高浓度超高分子量硅氧烷作为分散体以干颗粒形式存在于各种热塑性塑料中来解决这些问题。当以0.1%到1.0%的比例添加到聚丙烯或类似的热塑性塑料中时，预计树脂的加工和流动将得到改善，包括更好的模具填充、更少的挤出机扭矩、内部润滑、模具释放和更快的吞吐量。在较高的添加量下，1%到5%的硅氧烷有望改善表面性能，包括润滑性、滑动性、较低的摩擦系数、较高的抗磨损性和耐磨性。一项评价可涂性的研究表明，添加高达5%超高分子量硅氧烷的聚丙烯没有不良反应。与传统的低分子量硅氧烷添加剂相比，道康宁MB系列母粒有望带来更好的效益，例如，减少螺钉滑动、改善释放、降低摩擦系数、减少油漆和印刷问题以及更广泛的性能范围。限制：本产品未经测试，也不适用于医疗或制药用途。如何使用道康宁MB系列母粒，可以按照与它们所基于的热塑性塑料相同的方式进行加工。应将足够的道康宁MB50-001母粒与原始聚合物颗粒混合，以在最终产品中提供所需的硅氧烷含量。道康宁MB50-001母粒颗粒可以在单螺杆挤出机中混合或在注塑或挤出过程中添加到进料漏斗中。 Ultra-high molecular weight siloxane polymer. DOW CORNING MB50-001 Masterbatch is a pelletized formulation containing 50% of an ultra-high molecular weight siloxane polymer dispersed in polypropylene (PP) homopolymer. It is designed to be used as an additive in polypropylene-compatible systems to impart benefits such as processing improvements and modification of surface characteristics. Liquid siloxane plastic additives have been used for several years to improve the lubricity and flow of thermoplastics. They are effective in this role although some difficulties have been experienced in the incorporation of liquids into thermoplastic melts without the use of specialized equipment. It has also been difficult to produce masterbatches with greater than 20% liquid siloxane because of processing difficulty and bleed problems. The DOW CORNING® MB Series Masterbatches address these problems by supplying a high concentration of an ultra-high molecular weight siloxane as a dispersion in a dry pellet form in a variety of thermoplastics. BENEFITS When added to polypropylene or similar thermoplastics at 0.1% to 1.0%, improved processing and flow of the resin is expected, including better mold filling, less extruder torque, internal lubrication, mold release and faster throughput. At higher addition levels, 1% to 5% siloxane, improved surface properties are expected, including lubricity, slip, lower coefficient of friction, and greater mar and abrasion resistance. A study evaluating paintability showed no adverse effects in polypropylene with up to 5% ultra-high molecular weight siloxane added. The DOW CORNING MB Series Masterbatches are expected to give improved benefits compared to conventional lower molecular weight siloxane additives, e.g., less screw slippage, improved release, a lower coefficient of friction, fewer paint and printing problems, and a broader range of performance capabilities. LIMITATIONS This product is neither tested nor represented as suitable for medical or pharmaceutical uses. HOW TO USE DOW CORNING MB Series Masterbatches may be processed in the same way as the thermoplastics on which they are based. Sufficient DOW CORNING MB50-001 Masterbatch should be blended with virgin polymer pellets to give the desired siloxane level in the final product. DOW CORNING MB50-001 Masterbatch pellets can be added during compounding in a single screw extruder or added at the feed hopper during injection molding or extrusion. |
