Pelican cases are highly known for strength and durability. They offer exceptional water resistance. When a Pelican case is combined with foam inserts they protect your equipment and tools from damage. They are perfect for shipping or transporting gadgets like cameras, laptops, guns, iPods, TVs, and many other expensive brittle articles. The foam used in such cases is generally made of Polyurethane or Polyethylene. Polyurethane and Polyethylene are two common and popular types of foams that are known for their quality as well as strength. Depending on the product requirement, these foams are used for pelican case. A pelican case foam is chosen on the basis of the product's nature, weight, and the cushion required by it. Polyethylene and polyurethane are plastic materials that are used to manufacture a wide range of items. The chemical composition of these two types of foams is different. It is essential to use any of these foam pelican cases for properly protecting the items. A pivotal role is played by these two foams to protect the contents of your pelican case. With these foams, you get cushioned protection, which further helps in protecting your items against vibration as well as shock and unexpected mishandling. Polyethylene and polyurethane are different from each other. Some distinct differences between these foams are as such:Polyethylene Foam:Polyethylene is a flexible material that is commonly found in lots of consumer goods. Such type of foam is generally is created through a simple chemical structure that includes hydrogen atoms along with carbon atoms. It is a closed-cell foam that helps in not absorbing the liquids. This type of foam is also thermoplastic and does not split or break when it is bent. ●
It is a flexible foam that is widely used for amplifiers, large speakers, heavy cords or cables, microphone stands, as well as metal fixtures and heavy industrial machine parts, etc. This type of foam features a cross-link composition that is tightly woven and allows it to respond as a firmer type of foam.
●
Polyethylene foam is common in regular-use padding in which participants are landing on their hands or feet and is also what we use standard in our wall padding applications.
●
These are perfect for medium to heavyweight items and is also one of the best foam inserts that can be used for pelican cases to keep fragile items secure. It is difficult to bond a polyethylene foam to different subcomponents.
●
As compare to polyurethane foam, this foam is much denser and is often used for objects with higher sensitivity that require more rigid stability. They have a low resistance to heat. Polyethylene foam can be custom formulated for meeting exact design needs and its color is black.
