Is HDPE the same as Pehd?

High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a thermoplastic polymer produced from the monomer ethylene. It is sometimes called “alkathene” or “polythene” when used for HDPE pipes. HDPE is commonly recycled, and has the number “2” as its resin identification code.

What is HDPE used for?

Chemical containers: With its chemical resistant properties, HDPE is great for laundry, shampoo, conditioner, household cleaning products, motor oil, antifreeze and recycling bins. The strength of these bottles is increased when they’ve been colored or pigmented.

What is polypropylene used for?

Polypropylene (PP) is one of the most commonly used thermoplastics in the world. Polypropylene uses range from plastic packaging, plastic parts for machinery and equipment and even fibres and textiles.

What is LDPE used for?

Low density polyethylene (LDPE). This clear or translucent plastic exhibits flexibility, chemical resistance, and waterproofing capabilities. It is used in the manufacture of a wide range of products, including grocery bags, plastic wrap and film, flexible packaging material, and injection molded parts.

What is the difference between PE and LDPE?

Produced through free-radical polymerization, LDPE has the most long- and short-chain branching of any form of PE, resulting in its lower density. The branching keeps the molecular chains from packing tightly in its crystaline form, so LDPE has less tensile strength but greater ductility.

What is difference between PE and HDPE?

High-density polyethylene, known as HDPE plastic is a denser version of polyethylene typically used to make water and drain pipes because of its rigidness and crystalline structure. The main difference between HDPE and polyethylene or PE is that HDPE has PE as its base.

Is HDPE plastic safe?

HDPE plastic is currently considered a low-hazard plastic with a low risk of leaching. HDPE contains nonylphenol, which has been found to be dangerous to aquatic life. Nonylphenol is also an endocrine disruptor . This means it may affect your endocrine system, which controls your hormones.

Is HDPE eco friendly?

A variety of factors make HDPE a sustainable material that you can use in your facility, the major ones being the following: HDPE is made from recycled materials. HPDE contains between 25% and 100% pre-consumer material. Not only is HDPE sustainable by being made from recycled materials, but it’s also 100% recyclable.

Is polypropylene a good fabric?

As a fiber, polypropylene is strong, fade-resistant, and inherently stain resistant. Polypropylene is inherently stain resistant due to its non-dye able characteristics. This makes it ideal for upholstery and textile applications.
