    Application of plastic resins in the market

    Plastic is a familiar material and has many effects in everyday human life, but not everyone knows what effect plastic resins have and how they are applied. On the market today there are many types of plastic resins used in many different fields such as electronics, construction, refrigeration, ...
    This article will help us understand exactly what plastic beads are, how to classify them and how to apply each type of plastic particle in life?
    What is plastic beads?
    Plastic resins are an important material in the making of plastic products, in addition plastic resins are also known by other names as polypropylene plastic resins. Plastic resins are odorless, tasteless, non-toxic, transparent in color, but during the manufacturing process, they often mix plastic beads with color-forming particles to create a full-color finished product. . In addition, the plastic resin has a hard material, not soft like PE, not stretched so it is made into fiber.
    Depending on the characteristics and individual properties, each type of plastic resins has different effects in different industries.
    Plastic beads are created like?
    Based on the production process, plastic is divided into 2 types: virgin plastic and recycled plastic. Primary resin is a plastic product created from the fractional distillation of petroleum. Unused virgin plastic beads are usually natural white, when they are put into use, depending on needs, people will add colored beads to get the desired color.
    Recycled plastic is plastic that is re-produced from collected plastics. The types of plastic garbage collected are classified and recycled separately according to different processes. The plastic is then crushed, cleaned, dried and melted. At this time, the plastic mixture is transferred to the extruder, converted to plastic vermicelli or plastic pellets to continue to be put into other production processes.
    Types of plastic beads on the market
    3a. Primary plastic resins
    Primary resins include some types of plastic such as PP, PC, ABS, PS-GPPS, HIPS, POM, PA, PMMA, ... These are all virgin resins, not doped, without adding additives.
    The properties of primary plastic are soft, flexible, have great elasticity, and can withstand warping and pressure. The finished product of the primary plastic is quite aesthetically pleasing due to its smooth, glossy surface and bright colors. Primary plastic resins are often used to produce high-value items or products that require safety and high technology such as medical equipment, aircraft components, cars, ...
    3a1. PE plastic
    Among today's virgin plastic resins, PE is one of the safest materials. Every year, over 60 million tons of PE plastic are consumed, most of which is used to manufacture plastic packaging. PE resin is so popular because of its outstanding properties.
    The PE resin is transparent, slightly translucent, has a glossy surface and certain flexibility. PE plastic does not conduct electricity, does not conduct heat, does not allow water and gas to penetrate. However, PE resins are also susceptible to swelling and damage when exposed to essential oils or detergents. Even at high temperatures, PE resin cannot dissolve in water, fatty alcohols, acetone or herbal oils.
    Although they belong to the PE family, each PE resin has a different use. For example, VLDPE plastic is often used to manufacture gloves, shrink films, packaging or as a component in the transformation of other plastics. UHMWPE plastic is again used as cartridge yarn and liner because of its tough physical properties. While HDXLPE plastic is the main raw material for the production of plastic films, pipes, wires and cables. In addition, PE plastic pellets are generally used to produce plastic bags or containers with sizes ranging from 1 to 20 liters. PE is also used to manufacture bottle caps and to manufacture chemical equipment.
    3a2. PP plastic
    This plastic is made from polypropylene, is a hard and safe plastic, has the highest heat resistance, from 130 degrees C to 170 degrees C, so it is widely used in the manufacture of food containers, especially the food cans that can be used in the microwave. PP plastic is white, transparent, often used in the production of yogurt boxes, water bottles, medicine bottles, syrup or tomato sauce bottles, chili sauce, straws, ...
    On the market, PP plastic is one of the safe and extremely popular plastics, so it is not difficult to find products made from PP plastic. PP plastic is produced in the form of a multi-layer coating to increase the waterproofing of air and water vapor. Creating fibers, weaving into packaging for food, bulk grains. In addition, we can see products made from PP plastic such as water bottles, baby bottles, food storage boxes, toys for babies, ... because this material is extremely safe.
    3a3. PVC resin
    As a plastic made from polyvinyl chloride, this plastic can be found in products such as raincoats, construction materials, plastic flakes or boxes, shrink films of bottles, plastic bottles, and plastic films.
