LDPE is a flexible plastic with excellent chemical resistance and moisture barrier properties

LDPE, or low-density polyethylene, is a flexible plastic with a range of desirable properties. Notably, it possesses excellent chemical resistance and moisture barrier properties, making it suitable for a wide range of applications.

LDPE is highly resistant to many chemicals, including acids, alcohols, bases, and esters. This makes it ideal for use in industrial and laboratory settings, where it may come into contact with various substances. Its chemical resistance also makes it suitable for packaging materials, such as plastic bags and cling film, as well as agricultural applications like greenhouse film and irrigation tubing.

The moisture barrier properties of LDPE are also noteworthy. LDPE is highly effective at resisting moisture, which makes it ideal for use in products that need to be kept dry. This includes applications in agriculture, construction, and electrical cable insulation. For example, in construction, LDPE is used as a damp-proof membrane and pipe insulation to prevent moisture-related issues.

LDPE's flexibility, combined with its chemical and moisture resistance, makes it a versatile material. It can be easily processed and manufactured, making it a popular choice for various industries. LDPE is also recyclable, reducing waste and promoting sustainability. However, it's important to note that LDPE has some disadvantages, such as low strength and poor gas barrier properties, which may limit its use in certain applications.

Kydex thermoplastic is flexible, chemical-resistant, and fire and smoke-resistant

Flexible plastic materials are used in a variety of applications, from security glazing to playground equipment. One such material is Kydex thermoplastic, which is known for its flexibility, chemical resistance, and fire and smoke resistance.

Kydex thermoplastic is a highly versatile material that can be found in trade show booths, mass transit vehicle interiors, medical offices, and more. It offers excellent chemical resistance, making it ideal for use in clinical, food processing, and industrial contexts. Kydex thermoplastic is resistant to a wide range of corrosive chemicals, including acids, solvents, oils, and alcohols. It is also easy to clean and can withstand harsh cleaning agents without residual damage, making it suitable for hygiene-sensitive and high-traffic areas.

In addition to its chemical resistance, Kydex thermoplastic is known for its durability and impact strength. It is less likely to chip, crack, or break than other materials such as fiberglass or painted metal. Its scratch and abrasion resistance, along with its wide range of colour options, make it a popular choice for various applications. The integral colour throughout the sheet thickness of Kydex thermoplastic makes scratches and wear less noticeable, keeping surfaces looking newer for longer.

The fire and smoke resistance of Kydex thermoplastic is another key advantage. It meets flammability and smoke requirements for various industries, including aerospace and mass transit. Kydex T, for example, is a high-impact fire-rated sheet that offers greater resistance to a broad range of corrosive chemicals and cleaning solutions. The fire-resistant properties of Kydex thermoplastic have made it a popular choice for airlines, with companies such as United, American, and Delta adopting the material for their aircraft interiors.
