What is Plastazote LD33 Polyethylene Foam?

Plastazote LD33 polyethylene foam, a type of cross-linked closed-cell polyethylene foam, is synthetically created by expanding crude oil with nitrogen. This process results in a resilient and pliable material.

When compressed, each nitrogen-filled cell in Plastazote behaves like a balloon, allowing the foam to readily revert to its original shape. The closed-cell structure of Plastazote ensures its impermeability to air and moisture, effectively preventing the passage of liquids or absorption.

Polyethylene foams, including Plastazote LD33, are available in various densities, each tailored for specific applications. Foam density is quantified by measuring the weight or mass across the entire volume or within a cubic meter (m3). Higher foam densities impart greater weight and compactness to the material, consequently influencing its performance and properties.

    Why use Plastazote LD33 Polyethylene Foam?

    Plastazote LD33 polyethylene foam, boasting the attributes of LD18 with a higher density, serves as a cost-effective alternative to less inert materials like EPDM or Neoprene sponge. This versatile material is widely adopted across diverse industries, from arts and crafts to aviation.

    Due to its increased rigidity compared to lower-density foams, Plastazote LD33 is exceptionally well-suited for precision cutting and intricate part fabrication. Its low-density composition enables easy splitting, cutting, and shaping, making it an ideal choice for a variety of applications.

    This foam exhibits remarkable recovery following compression and impact, along with robust resistance to an array of chemicals, solvents, acids, alkalies, and certain oils. Such resilience renders Plastazote LD33 suitable for various industrial uses.

    Plastazote materials, including LD33, are characterized by their lightweight nature and lack of chemical agents, making them an excellent choice for "clean" applications in sectors like food, pharmaceuticals, and scientific research. LD33 polyethylene foam further provides exceptional thermal properties and delivers high levels of vibration and shock absorption, making it suitable for applications such as protective packaging and the creation of gaskets and seals.

    Advantages of using Plastazote LD33 Polyethylene Foam

    The utilization of Plastazote LD33 foam confers numerous advantages, rendering it indispensable across a multitude of industries and applications. Plastazote, being a synthetic material, is engineered to meet diverse requirements and is available in a variety of grades, densities, and colors. LD33 stands out for being odorless, lightweight, buoyant, non-toxic, and capable of resisting a wide range of oils, solvents, acids, and alkalis.

    Its closed-cell structure ensures liquids cannot permeate, simplifying cleaning while rendering it weatherproof and UV-stable. Plastazote LD33 polyethylene foam is the preferred choice for protective packaging, particularly case inserts, owing to its excellent recovery from repetitive impacts and impressive energy absorption, which also imparts strong thermal insulation properties.

    Employing such materials for packaging and transporting goods translates into significant cost savings, thanks to the reduced product damage during transit and storage. This cost-effectiveness is an attractive proposition for customers seeking to safeguard their products effectively.
