高性能聚丙烯（PP）树脂Lyondellbasell Industries已选择由全球清洁设备领先的生产商AlfredKärcherGmbH＆Co。kg生产新的工业清洁设备。app亚博体育Moplen EP240T用于生产该公司新的中类和高端热水高压清洁剂的底盘。
A Moplen EP240T polypropylene resin from LyondellBasell has been selected for the production of a new series of industrial cleaning equipment by Alfred Kärcher GmbH & Co. KG, the world’s leading producer of cleaning equipment. Moplen EP240T is being used to produce the chassis of the company’s new midclass and high-end range of hot water high-pressure cleaners. The chassis represents Kärcher’s first use of a polymer in the application, which traditionally has been produced using steel.
The new chassis represents Kärcher's first use of a polymer in the application, which traditionally has been produced using steel. Compared to standard PP resins, Moplen EP240T offers a unique balance of advanced mechanical properties, including high flowability, impact strength and chemical resistance. Kärcher's cleaning equipment is used to clean automotive engines, agricultural and industrial machinery and therefore the cleaner application required a resin that could stand up to the rigors of outdoor environments.
从钢到塑料
As a load-bearing element for the cleaner, the chassis features very complex geometry that includes more than 300 pieces; the part is 1254 mm long, 747 mm wide, 495 mm high and weighs 22 kg. "Our new model required a material that permitted more design freedom and production flexibility than steel," said Bernd Gaßmann, Process Coordinator at Kärcher. "By using Moplen EP240T, we were able to eliminate several manufacturing steps, and the outstanding processability of the material enabled us to include parts such as the air duct and the holding tanks for water and detergents directly into the chassis instead of assembling these parts in a separate manufacturing step."
Moplen EP240T树脂符合Kärcher对成品零件的苛刻要求，正在系列中生产六种型号。Gaßmann说：“由于其出色的融化速率（MFR），诸如工业清洁剂等苛刻的应用所需的抗击力和僵硬，来自Lyondellbasell的PP树脂已经证明了其在其他各种Kärcher应用中的适用性。”
Outstanding flowability
刚度和冲击电阻的可比平衡的标准PP等级的MFR为25 g/10min，而Moplen EP240T的MFR的MFR为48 g/10min。“一方面，流动性具有僵硬和抗冲击力，另一方面是截然相反的力。但是，莫普伦树脂在Lyondellbasell的应用开发和技术服务经理Daniel Schneider表示。“Kärcher还需要高化的化学耐药性，PP可以解决这种特定的外部应用应用需求。”
Kärcher的制造过程还需要树脂具有提高的焊接性。Schneider补充说：“Kärcher使用了最新的红外焊接技术，并且由于聚合物的平衡结构，Moplen EP240T适合这种处理方法。”
Before the cleaner entered mass production, the Moplen grade had to pass Kärcher's numerous stringent test methods. "As a producer of high-end units, the materials we use must withstand challenging tests," added Gaßmann. "Moplen EP240T PP resin delivered good results in terms of elongation, impact resistance at -20°C, and density. By using the lowest-density polymer available, we were able to save costs."
"This application success clearly illustrates PP's ability to continuously deliver innovative and versatile solutions," said Paul Turner, vice president of LyondellBasell's polypropylene business in Europe.

世界上最大的清洁设备制造商Kärcher是一家家族拥有的公app亚博体育司，在2008年售出了638万辆。同年，Kärcher重新推出了其基准中级和高端热水高压清洁剂。
根据Gaßmann的说法，“我们对这个新的和改进的清洁剂的潜力感到非常兴奋。该单元满足了所有用途的特定消费者需求，并且由于应用程序中实现的创新数量，我们的重新启动系列已成为基准。清洁性能，移动性和环境保护。”
