Plastic comes from petroleum-based resins and can be shaped in many ways without breaking. It belongs to the group of polymers, very large molecules, with special and varied characteristics. There are many types of plastics. The most rigid, the fine and easy to knead, the transparent ones, etc.
They are divided into two groups according to their melting or melting characteristics: thermoplastics and thermosets. Some of the reasons for the success of plastic are its lightness, the fact that it is malleable and does not shatter when it breaks.
Advantages of high density thermoplastic
The thermoplastics are those which soften when heated and can be molded, and are solid when cooled and take a new shape. This process can be repeated several times. They correspond to 80% of the plastics consumed. They are used in heavy industries, such as making Radiation shielding materials.
• One of the most representative things of engineering thermoplastics is the balance between their properties.
• They make it totally suitable for its applications in the field of engineering.
• The most recognized families as engineering thermoplastics are: Polyamides, Polycarbonates, thermoplastic polyesters.
• High impact resistance, good electrical insulation capacity, fairly high usage temperatures, corrosion resistance and resistance to chemical attacks.
Already thermosets are those that do not melt and that although they cannot be molded. It can be sprayed and leveraged as cargo or being incinerated for energy recovery.
The uses of thermoplastics in various industries
PET – Polyethylene Terephthalate: Soft drink bottles, pharmaceutical products, cleaning products, waterproofing blankets and textile fibers.
PEDB – Low Density Polyethylene: Food packaging, industrial bags, garbage bags, agricultural canvas, flexible packaging films and toy labels.
HDPE – High Density Polyethylene: Packaging for cosmetics, Radiation shielding, chemicals and cleaning products, tubes for liquids and gas, fuel tanks for automotive vehicles.
PVC – Polyvinyl Chloride: Bottles of mineral water, tubes and connections, footwear, electrical cable covers, medical-surgical equipment, frames and coverings.
PP – Polypropylene: Pasta and biscuit packaging, margarine jars, disposable syringes, medical and surgical equipment, textile fibers and threads, housewares, auto parts (car bumpers).
PS – Polystyrene: Disposable cups, insulating plates, stereos and TV, food packaging, refrigerators, school supplies.
Its resistant quality is spectacular
For the excellent chemical and thermal resistance, they are also very resistant to environmental adversities. And is therefore anti-wear. It is very rigid, tenacious and flexible at the same time therefore adaptable to various situations. Last but not least, it has a wide workability.
High density thermoplastic also known by the name of engineering techno-polymers, are plastic materials that boast significant strength and rigidity characteristics. Precisely for these physical properties, they are used for various applications to replace traditional metals.
The HDPE is also distinguished by a certain dimensional stability and for the preservation of good mechanical properties even at high temperatures. They can be worked with conventional technologies.
Quality, solidity, wide choice of products, so these are just some of the benefits that HDPE are able to offer to those who use them. The engineering polymers stand out for their high physical-mechanical characteristics. A valid alternative to traditional materials such as, stainless steel and other metals.
