摘要： Disclosed herein is a process for printing on a microporous substrate using a laser to melt or soften the substrate so that the pores collapse and produce clear regions on a white background. The preferred substrate is one based on polypropylene where the microvoids are produced by orienting an extruded, precursor sheet that contains the beta crystalline form of polypropylene. A dark co-extruded layer or a pigmented adhesive can be placed on the non-laser treated side of the film, so that the treated side shows the color of the backing layer through the clear regions. This type of printing or laser marking does not require any inks, solvents, or other consumable additives, and the printing can be done at very high production rates and at low cost. The small void size of the film allows for fine print detail and excellent print contrast.

摘要： Beta nucleation agents are used to impart improved properties in polypropylene materials such as sheets and speciality items, for example, geogrids. A convenient way of incorporating beta-nucleating agents into polypropylene used to fabricate an extruded product is through the use of a concentrate.

摘要： A method and device are disclosed for the determination of the environmental stress crack resistance (ESCR) of polymer articles made from polymers such as acrylonitrile-butadiene-styrene copolymers, polycarbonate, polystyrene and blends thereof. The method and device involve the external application of stress to an unstressed test article which has been exposed to a stress cracking agent. The stress is induced by means of a weight located below the horizontal plane of the plastic article. The time between the application of stress and the cracking of the test article is measured to compute a characteristic ESCR parameter and thereby evaluate the environmental stress crack resistance of the article.

摘要： Improved extruded polypropylene sheets containing a high level of beta crystallinity and A process for making such sheets are disclosed herein. The polypropylene sheets comprise a resinous polymer of propylene and an effective amount of beta spherulites. Uniaxially or biaxially oriented mesh structures produced from the disclosed sheets exhibit lower density, higher strength, and higher torsional rigidity than polypropylene meshes without beta spherulites. Thus, lighter weight mesh structures which meet all of the physical property requirements for end-use applications, such as reinforcing grids to stabilize concrete and soil in civil engineering and landfill applications, are produced. The lighter weight extruded beta-nucleated sheet can also be stretched at higher line speeds, thereby reducing manufacturing costs.

摘要： An improved extruded polypropylene sheet that contains a high level of beta crystallinity and a process for making such sheets are disclosed herein. The polypropylene sheet contains at least one layer of a resinous polymer of propylene and an effective amount of beta spherulites. The beta spherulites in the sheet are produced by the incorporation of a beta nucleating agent in the polymer. The presence of the beta spherulites in the sheet facilitates the process of post-stretching the perforated sheet to produce a uniaxially or biaxially oriented mesh structure, and also broadens the temperature range over which this stretching can be performed. The final mesh has a lower density than a polypropylene mesh without beta spherulites. The perforated beta nucleated sheet also exhibits different stretching characteristics during the orientation steps such that more resinous polymer is drawn out of the node junction region between the machine direction and transverse direction oriented strands and a greater percentage of the web area has a solid polymer structure. This altered stretching behavior results in an oriented web that has higher strength and torsional rigidity characteristics. Thus lighter weight mesh structures which meet all of the physical property requirements for end-use applications, such as reinforcing grids to stabilize concrete and soil in civil engineering and landfill applications, are produced. The lighter weight extruded beta nucleated sheet can also be stretched at higher line speeds, thereby reducing the manufacturing costs.

摘要翻译： 本文公开了包含高水平的β结晶度的改进的挤出聚丙烯片和制造这种片的方法。 聚丙烯片材含有至少一层丙烯的树脂聚合物和有效量的β球晶。 片中的β-球晶通过在聚合物中引入β成核剂而产生。 片中β-球晶的存在有助于拉伸穿孔片材以产生单轴或双轴取向的网状结构的过程，并且还拓宽了可进行该拉伸的温度范围。 最终的网格具有比没有β球晶的聚丙烯网格更低的密度。 穿孔的β-成核片材在取向步骤期间也显示出不同的拉伸特性，使得更多的树脂聚合物从机器方向和横向取向的丝线之间的节点连接区域中拉出，并且更大百分比的幅材区域具有固体聚合物结构。 这种改变的拉伸行为导致具有较高强度和扭转刚度特性的定向网。 因此，产生了满足最终用途应用的所有物理性能要求的较轻的网格结构，例如在土木工程和填埋应用中稳定混凝土和土壤的增强网格。 较轻重量的挤出β-成核片材也可以以更高的线速度拉伸，从而降低制造成本。
