PP, or polypropylene, is a thermoplastic polymer made from the propylene monomer. Resistant to acids bases, and solvents, PP is used to make textiles, stationery, car parts, packaging materials, and reusable containers. HDPE stands for high-density polyethylene. This polyethylene thermoplastic is made when intense heat is applied to petroleum. HDPE is used in various applications like wood-plastic composites, composite wood, in landfills as cell lining, plastic surgery applications, and natural gas pipes.

What are the Differences Between PET and HDPE?

PET and HDPE differ most notably in their appearance. PET is clear, resembling glass in appearance, while HDPE is more flexible and opaque in appearance. These two materials also differ in their usage. HDPE is commonly used to manufacture plastic laboratory supplies and plastic bottles, whereas PET is commonly used for food packaging and personal care products. Lastly, PET is shatterproof, lightweight, and inert, while HDPE provides more rigid strength and chemical resistance.

Durable and robust, PET plastic is the most common thermoplastic polymer resin in the polyester family. Offering significant wear and chemical resistance, PET also has low moisture absorption and superior UV resistance. It is used in fibers for clothing and containers for liquids and foods.

What is Polypropylene Plastic?

Polypropylene plastic is made by combining propylene monomers. This thermoplastic can be used in numerous different applications, including consumer packaging material, plastic hinges, waterproofing insulation, and more.

Is Polypropylene Plastic Toxic to Humans?

Polypropylene plastic is considered a low-toxin, heat-tolerant material. This kind of plastic is used in a variety of applications related to human consumption, including straws, yogurt containers, bottles, and even medical devices.

Is Polypropylene Plastic Food Safe?

Polypropylene plastic used in food containers will not leach harmful chemicals into the food orf liquid they store. Marked with either a type 4 or type 5 symbol, polypropylene is commonly used to store foods and liquids meant for human consumption.

How Strong is Polypropylene Plastic?

Polypropylene plastic is a strong and rigid material that can effectively retain its strength across a variety of different applications. In fact, polypropylene plastic is so strong, that pound-for-pound, products made from the material are on average, three times stronger than those made with steel.
