What is PP plastic? Properties and applications of PP

What is PP plastic?

PP (PolyPropylene) belongs to the group of virgin plastics, a polymer, a product of the polymerization of Propylene.

Charateristics of PP plastic

High mechanical strength (tear and tensile strength), quite hard, not as flexible as PE, not stretched and therefore made into fibers. Especially the ability to tear easily when there is a small cut or puncture. Transparent, high surface gloss for high printability, clear print. PP is colorless, odorless, tasteless, non-toxic. PP plastic pellets burn brightly with a light green flame, have a flexible flow, and have a burning smell similar to that of rubber.

Applications of PP plastic

Used as a single-layer packaging for food preservation, which does not require strict anti-oxidation. Forming yarn, weaving into packaging for food and grain in bulk. PP plastic beads are also produced in the form of a coating film for multi-layer films to increase gas and vapor permeability, create high printing ability, and easy to tear to open the package (due to the availability of a cut). and create a high gloss for the packaging.

PP plastic include the following groups

• PP Yarn:

PP Yarn has the full name of Polypropylene Yarn. This is a kind of polymer product of Propylene polymerization.

PP Yarn belongs to the group of PP plastic beads, so this material possesses all the characteristics of Polypropylene in terms of mechanical strength, water resistance, colorless, and odorless.

Application: blowing bags, woven packaging, spinning...

• PP Lamination:

PP injection has the full name of Polypropylene Injection Molding. This is a kind of polymer product of propylene polymerization. PP Injection is widely used in products that need to be molded.

Pressed PP has mechanical strength, water resistance, colorless, odorless and is widely used in products that need to be pressed, products that require high formability and good mechanical resistance.

Application: home appliances, toys, food boxes..

• PP film:

PP film has many outstanding features such as scratch resistance, impact resistance, heat resistance, corrosion resistance, termite and bacteria resistance, anti-static.

Application: coating on packaging, household appliances, industrial goods...

• PP Lamination:

PP lamination with the main structure is PP Polypropylene, which does not contain formaldehyde, preservatives, heavy metals and other harmful substances, complying with the requirements of interior safety for health and environmental protection.

PP film mechanical strength, water resistance, colorless, odorless.

Application: coating on packaging, coating household appliances, coating industrial items.

• PP Block Copolymer:

Co-polymer impact polypropylene (PP) is a thermoplastic produced by polymerization of propylene. The copolymer is formed by providing a heterophase structure into the semi-crystalline PP homopolymer matrix.

Polypropylene is one of the most versatile plastic materials in the world. Because of its wide range of products with many characteristics, it is used to manufacture everything from packaging materials and household goods to general automotive and electrical applications.

Application: thick extrusion, tube, film, heat exchanger, press mold (cap and lock, pin, pitch, automotive, decoration).

• PP Nonwoven Fabric:

PP non-woven fabric is made from Polypropylene granules heated at standard temperature, spun into yarn, pressed on a conveyor belt, and undergoes a cooling process to create non-woven fabric.

PP non-woven fabric has outstanding properties such as: high absorbency, waterproofing, elasticity, durability, heat insulation, sound insulation, filtering. Therefore, PP non-woven fabric is widely applied in the fields of life such as apparel, fashion, medical protective equipment, industry, consumer goods...

Application: production of fabric, non-woven yarn…
