Low-density polyethylene (LDPE) is a thermoplastic made from the monomer ethylene. It was the first grade of polyethylene, produced in 1933 by John C. Swallow and M.W Perrin who were working for Imperial Chemical Industries (ICI) using a high pressure process via free radical polymerization. [1] Its manufacture employs the same method today.

聚乙烯泡沫塑料(polyethylene plastic)是以聚乙烯树脂为主体，加发泡剂、交联剂和其它添加剂制成，是十分重要的一种缓冲材料。 它具有密度小，最小可达0.01g/cm3；缓冲性、耐热性、吸水性小；化学性能稳定，不易受腐蚀；机械性能好，坚韧、有挠性、耐摩擦 ...

Polyethylene is a closed cell foam, also referred to as a PE foam or LDPE foam. The material starts off as a thermoplastic which is then blown into a foam format. This is a highly durable as well as versatile product. The high compression rates that polyethylene offers enable it to maintain its resilience under repeated impact.

XPE的主要原料是低密度聚乙烯 (LDPE)，辅以发泡剂、交联剂等辅料，经熔融混匀挤塑成型后，再经高温连续发泡而成的泡棉制品。 XPE泡棉是一种符合国际环保标准的功能性高分子发泡材料，相比其他PE或者非PE类的泡棉（泡沫）材料，XPE泡棉在产品耐用性、抗光照、抗物理撞击等方面表现更佳。 材料本身化学性质稳定、不易分解、无气味、弹性好、抗老化、耐腐蚀是制造爬行垫、隔音垫、保温隔热层、汽车软内饰等的优选材料。 IXPE的主要原料是低密度聚乙烯 …

2020年1月16日 · LDPE is commonly used in applications where flexibility and low cost are important, such as in packaging, bags, films, and coatings. It is also recyclable, which makes it an environmentally-friendly choice. LDPE is resistant to moisture and some chemicals, but not as much as HDPE.

2017年1月10日 · SABIC has launched a new dedicated low-density polyethylene foam grade, SABIC LDPE HP0824NDF, to broaden the application window for the tape, seal and underlayment market. The advantages of the new grade are high viscosity, giving good head pressure for uniform and thicker foam thickness, relatively …

The Zotefoams Plastazote LD45 is a closed cell crosslinked polyethylene foam design to increased stiffness, improved temperature resistance and improved moldability. It is engineered to offer superior performance and lighter weight.

Polyethylene foam is a plastic-like, lightweight, but durable, closed-cell foam that is used for a multitude of purposes. It is long-lasting, resistant to moisture and chemicals, and great for dampening vibrations.

Our PE foams are classified as #4 low-density PE (LDPE) material and can be recycled in LDPE recycling systems, including our closed-loop recycling program. Check your local recycling program for specific regulations.
