DISTINGUISHING PRIMARY PLASTIC AND RECYCLED PLASTIC FOR CORRECT USE

Plastic is a miraculous invention of mankind, Currently plastic is present in all areas of life. Therefore, we should also be equipped with a little knowledge of distinguishing between virgin plastic and recycled plastic to use plastic properly in life..

1.What is primary plastic??

Primary plastics include some types of plastics such as PP, PC, ABS, PS-GPPS, HIPS, POM, PA, PMMA… These are all pure plastics, unstable, no additives added.

The characteristic of virgin plastic is soft, flexible, has great elasticity, Resistant to warping and pressure. Finished products of virgin plastic are quite aesthetically pleasing due to their glossy surface, smooth and bright color.

Depending on the characteristics of each type of primary plastic, these plastics are currently used in many industries such as food packaging., helmet (impact), golf club head, Plastic pipe systems can withstand pressure... In addition, Virgin plastic is also present in the automobile manufacturing industry, electronic, medical equipment…

2.What is recycled plastic??

Regeneration plastic ( Also known as recycled plastic ) is plastic that is remanufactured from collected plastic. The collected plastic is crushed, clean, drying and melting. Afterward, The plastic mixture is passed through the extruder, Press the plastic to convert it into noodles or plastic granules.

Recycled plastic is used as a raw material for production in many fields such as industry, construction or environment.

Main types of recycled plastics: HDPE, PP, PE, ABS, PVC…

a. HDPE recycled plastic:

HDPE (High Density Popyethylene) recycled from hot steam pipes, Pipes serving the fiber optic postal industry, drainage pipe, etc. HDPE is used to produce bags, packaging, plastic can, household appliances, blow the bag, environmental products.

b. PP recycled plastic

PP (Polypropylene) Regenerated from packaging, rope, carpet, membrane, stationery, Other PP plastic parts such as: laboratory instruments, very well, car interior parts, etc. PP recycled plastic products have tough physical properties, Slightly hard and highly durable.

c. PE recycled plastic

Is the abbreviation for Polyethylene or Polyethene recycled plastic granules, Recycled from nylon bags, agricultural mulch film. PE recycled plastic products have flexible and tough physical properties.

d. ABS recycled plastic granules

ABS (Acrylonitrin butadien styrene) is a very flexible plastic, withstand strong impacts and are recycled from injection molding products, keyboard, office machine, car parts, motorbike, helmet, toy, lightweight products, hard, malleable like a tube, box cover, musical instruments, reserve the car, spool and is used to produce lower grade products than the original product.

e.PVC recycled plastic granules

Is the abbreviation for Polivinyl chloride recycled plastic granules regenerated from PVC plastic pipes, hard plate, oil pipes, power plug…. During recycling, PVC plastic is mixed with some additives such as heat stabilizers, types of agents: UV absorption, lubrication, plasticization, processing assistant, increased stiffness, impact, fireproof, baking powder to suit the features of each product type.

3.Fireproof fiberglass composite resin

In addition to primary plastic and recycled plastic, There is another type of plastic that is also very present in life. It is fireproof fiberglass composite plastic.

Composite plastic – FRP plastic ( Fibeglass Reinfored Plastic) Also known as glass fiber reinforced plastic, it is a combination plastic consisting of a resin phase and a filler phase, The purpose is to increase the mechanical properties of the original plastic.

Composite plastic contains glass fibers, carbon fiber, ceramic fiber, Heat-stable fibers and some other fiber groups... have the effect of increasing mechanical properties, adhesion, wear resistant, scratch resistant, heat resistant.

Because of the above advantages, Composite plastic is currently used in many industries such as rocket engine casings, plane, spaceship, petroleum pipes, clean water, wastewater, chemicals, waste... and present in many other fields.

Above is some basic knowledge about virgin plastic, recycled plastic, Fire-resistant composite plastic, Hopefully it can help you distinguish the types of plastic and plastic utensils around you more easily. Since, Choose plastic products that suit individual and family needs.
