Polymers
Polyethylene (PE)
Among the most important and versatile of the hundreds of commercial plastics is polyethylene. Polyethylene is used in a wide variety of applications because, based on its structure, it can be produced in many different forms. The first type to be commercially exploited was called low density polyethylene (LDPE) or branched polyethylene. Another forms of polyethylene are High Density Polyethylene (HDPE) and Linear Low Density Polyethylene (LLDPE).
LDPE
Low Density Polyethylene
Low density polyethylene (LDPE) is used mainly in film applications for both packaging and non-packaging applications. Other markets include extrusion coatings, sheathing in cables and injection moulding applications. PETRONYX GmbH is a leading firm in trading and supplying premium quality LDPE Granules manufactured according to highest international standards.
LLDPE
Linear Low Density Polyethylene
The popularity of linear low density polyethylene (LLDPE) is due to its higher tensile strength and superior impact and puncture resistance than its low density polyethylene (LDPE) rival. This has allowed converters to make thinner films without sacrificing strength, saving material and reducing costs. Globally, around 80% of LLDPE goes into film applications such as food and non-food packaging, shrink/stretch film and non-packaging uses.
HDPE
High Density Polyethylene
High-density polyethylene (HDPE) is one of the most commonly used plastics. It is typically found in milk jugs, plastic drums, plastic bags and refillable plastic bottles, manufacturing lawn and garden products, buckets, crates, office products and automobile parts.
Polypropylene (PP)
Polypropylene offers a good balance of thermal, chemical and electrical properties at a rather low cost. It also has the ability to resist cracking and is very easy to fabricate with standard wood and metals working tools. All Polypropylene can also be welded to itself which is a great feature when designing and building tanks and fume hoods. Due its mixture of rigidity and comfort, it is also utilized in manufacturing orthopetic braces.
Polypropylene is available in two basic types. PP-Homopolymer (PPH) as well as PP-Copolymer (PPC). PETRONYX GmbH endeavours to balance prime quality and competitve price for both PPH and PPC.
PPH
Polypropylene Homopolymer
Polypropylene Homopolymer (PPH) is the most widely utilized. PPH offers a high strength to weight ratio and is stiffer and stronger than copolymer, This combined with good chemical resistance and weldability allows this material to be used in many corrosion resistant structures.
PPC
Polypropylene Comopolymer
Polypropylene copolymer (PPC) is a bit softer but have better impact strength, is tougher and more durable than homopolymer polypropylene. Copolymer polypropylene tends to have better stress crack resistance and low temperature toughness than homopolymer at the expense of quite small reductions in other properties.
Polystyrene (PS)
Polystyrene (PS) is a thermoplastic resin with good processing properties. It is used in many applications including disposable plates and cups, meat trays and compact disc cases. Polystyrenes have well-balanced physical properties and are generally transparent, but available in various colors. Several different grades of PS are available, from which PETRONYX GmbH offers three grades, namely General Purpose PS (GPPS), High Impact PS (HIPS) as well as Expandable PS (EPS).
GPPS
General Purpose Polystyrene
General Purpose Polystyrene, often referred to in its acronym form GPPS, is made from a styrene monomer polymer through a process of suspension.General Purpose Polystyrene is relatively strong and weather resistant. The material flows easily, making it perfect for usage in moulds with end products such as toys, CD cases, hangers, and plastic cups. The polystyrene is used in applications such as IT equipment, clear jewel boxes and other types of enclosures.
HIPS
High Impact Polystyrene
Onece GPPS is processed with rubber, HIPS is the result. HIPS is widely used in the food packaging industry because of its unique qualities of strength, hygiene, visual appearance, and ability to retain heat, while also not deforming because of general warm water application.
EPS
Expandable Polystyrene
Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam. It is usually white and made of pre-expanded polystyrene beads. EPS is used for many applications e.g. trays, plates, bowls and fish boxes. Other uses include molded sheets for building insulation and packing material ("peanuts") for cushioning fragile items inside boxes. Sheets are commonly packaged as rigid panels (size 4 by 8 or 2 by 8 feet in the United States), which are also known as "bead-board".
Polyethylene Terephthalate (PET)
PET has good barrier properties against oxygen and carbon dioxide. Therefore, it is utilized in bottles for mineral water . Many beverages, food items and other consumer products are delivered in bottles or packages made from PET. In the context of textile applications, PET is referred to by its common name, polyester, whereas the acronym PET is generally used in relation to packaging. PETRONYX GmbH trades and supply both Bottle Grade (PET) and Textile Grade (Polyester).
PET
Bottle Grade
Bottle grade PET Plastic is a kind of transparent, wear-resisting and corrosion-resisting plastics with high strength and smooth finish; it is widely used for PET bottles of mineral water, juice, edible oil, pharmaceuticals, cosmetics, etc.
Polyster
Textile Grade
Polyester fabrics can provide specific advantages over natural fabrics, such as improved wrinkle resistance, durability and high color retention. As a result, polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties.
Polyvinyl Chloride (PVC)
Polyvinyl chloride (PVC) is the third-most widely produced synthetic plastic polymer, after polyethylene and polypropylene. PVC comes in two basic forms: rigid and flexible. The rigid form of PVC is used in construction for pipe and in profile applications such as doors and windows. The flexible form is used in plumbing, electrical cable insulation, imitation leather, signage, inflatable products, and many other applications.
Acrylonitrile Butadiene Styrene (ABS)
ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. ABS resins are easily injection molded, extrusion molded, vacuum molded, thermoformed and blow molded. For the majority of applications, ABS can be used between −20 and 80 °C (−4 and 176 °F). The most important mechanical properties of ABS are impact resistance and toughness. It is therefore used in manufacturing products such as musical instruments, automotive bumper bars, household goods like washing machines, refrigerator and computer equipments like keyboard keycaps.
