Polymères Plastiques

✮Low Density Polyethylene, or LDPE for short, is another key plastic polymer in a variety of applications. This material is noted for its flexibility and malleability, making it ideal for a wide range of products. LDPE is commonly used in flexible packaging, plastic bags, protective films and toys, among other products. Its versatility is due to its ability to easily adapt and conform to different shapes, making it a popular choice when looking for a lightweight, easy-to-handle plastic. In addition, LDPE is known for its resistance to water and chemicals, making it suitable for applications where a protective barrier is required.

✮Linear Low Density Polyethylene, or LLDPE for short, is another type of plastic polymer that shares some characteristics with LDPE but with enhanced properties. Like LDPE, LLDPE is known for its flexibility and impact resistance. What distinguishes LLDPE is its higher tensile strength, which makes it more suitable for applications where higher mechanical strength is required. This type of polyethylene is commonly used in stretch films, flexible packaging, coatings and industrial applications that demand a combination of flexibility and strength.

★Polypropylene, known as PP, is another widely used plastic polymer with diverse applications. This material is prized for its versatility and resistance to moisture, chemicals and heat. PP is commonly used in a variety of products, from packaging to textiles to automotive components. One of the outstanding characteristics of PP is its ability to withstand high temperatures, which makes it suitable for applications requiring thermal stability. In addition, polypropylene is lightweight but robust, which facilitates its use in products that must be durable but not too heavy.

★Polyethylene Terephthalate, known as PET, is a widely used plastic polymer known for its transparency, lightness and strength. This material is commonly used in the manufacture of food and beverage packaging, as well as in the production of textile fibers. What makes PET so popular is its ability to be molded into various shapes and its resistance to moisture and gases. Water bottles, soft drinks and food containers are common examples of products made from PET. In addition, PET is recyclable, making it a sustainable option for packaging.

★Polyvinyl Chloride, known as PVC, is a versatile plastic polymer used in a wide variety of applications. One of PVC's notable characteristics is its durability and corrosion resistance, making it ideal for applications involving contact with water, chemicals and harsh weather conditions. PVC is commonly used in the manufacture of pipes and fittings for potable water and sanitation systems. In addition, this material is widely used in construction for the manufacture of profiles, panels and cladding due to its strength and versatility. It is also found in everyday products such as toys, footwear and decorative items.

★ Vinyl Acetate, known as EVA, is a thermoplastic copolymer that combines properties of flexibility, elasticity and strength. This material is known for its softness and ability to regain its original shape after deformation, making it ideal for applications requiring cushioning and comfort. EVA is commonly used in the manufacture of products such as shoe soles, exercise mats, toys, and packaging. Its flexibility and moisture resistance also make it useful in applications ranging from the sports industry to the manufacture of household products.

★Acrylonitrile Butadiene Styrene, known as ABS, is a widely used thermoplastic polymer that combines the properties of three monomers: acrylonitrile, butadiene and styrene. This material is known for its strength, stiffness, and toughness, making it versatile for a variety of applications. ABS is commonly used in the manufacture of durable and strong plastic parts, such as appliance housings, toys, automotive parts, and electronic products. In addition, it is easy to mold and has good impact resistance, making it suitable for applications requiring durability and dimensional stability.

★Polycarbonate, known as PC, is a tough, transparent thermoplastic that is noted for its optical clarity and durability. This material is known for its impact resistance, high temperature and self-repairing properties. In addition to its transparency, PC is UV resistant, making it suitable for outdoor applications. PC is used in a variety of applications, from the manufacture of eyeglass lenses to the production of electronic device housings, polycarbonate windows and lighting components. Its combination of properties makes it suitable for situations where mechanical strength and transparency are required.

★Polystyrene, known as PS, is another commonly used thermoplastic polymer. This material is known for being lightweight, rigid and economical. There are two main forms of polystyrene: glass (PSC) and high impact polystyrene (HIPS). Crystal PS is transparent and is commonly used in the manufacture of disposable containers, cups, plates and utensils. On the other hand, HIPS is a high-impact variant that is used when higher impact resistance is required, such as in the manufacture of toys, electronics housings and some packaging.

★Polyoxymethylene, known as POM or acetal, is a thermoplastic polymer with exceptional mechanical properties. This material is known for its high strength, stiffness and low friction, making it suitable for applications requiring precision parts and low friction. POM is commonly used in the manufacture of engineering parts, such as gears, bearings, and machinery parts. Its wear resistance, dimensional stability and ability to operate in high humidity environments make it valuable in industrial and automotive applications.

Polyketones✶ are a family of high-performance thermoplastic polymers.

Random copolymers✶ are created by adding ethylene to propylene during the polymerization process. This random inclusion of ethylene into the homopolymer matrix during polymerization produces PP resins that have excellent transparency and gloss, lower stiffness compared to PP homopolymers, but higher impact properties at room temperature.
