PET Flake

Polyethylene terephthalate (sometimes written poly(ethylene terephthalate)), commonly abbreviated PET, PETE, or the obsolete PETP or PET-P is a thermoplastic polymer resin of the polyester family and is used in synthetic fibers; beverage, food and other liquid containers; thermoforming applications; and engineering resins often in combination with glass fiber.

Recycled PET flakes has today become one of the major raw materials of the recycling industry. We supply a wide-range of high-quality PET flakes in addition to fibre-grade flakes that have been sought after by various industries including textiles.

PET (polyethylene terephthalate) represents 70% of the world’s textile fibers production. This material has a slow aging when exposed to UV rays and weathering. It can be recycled several times.

The growing application of plastics in industrial and consumer applications worldwide, combined with consumers’ growing awareness around plastic recycling has led to an increase in demand for recycled plastic materials.

PP, HDPE GRANULE

Polypropylene is a very resistant and rigid thermoplastic polymer. Its use in industry is mainly due to its characteristics of resistance to acids and alkalis, its ease of processing and good temperature resistance.

While PP is easily among the most popular plastic packaging materials in the world, only around 1% is recycled, which means most PP is headed for the landfill. These decompose slowly over 20-30 years. This raises severe environmental issues, quite apart from toxic additives in PP such as lead and cadmium. Incineration may release dioxins and vinyl chloride, both of which are poisonous.
Recycling of polypropylene is emerging as an important, and economically viable, option on a large scale.

The main benefit of recycling PP is the reduction in the consumption of raw, finite resources such as oil and propene gas. It is estimated that around 8% of the oil used worldwide (around 400 million tons) is utilized in the traditional methods of plastic production, with 4% as ‘feedstock’ and another 4% in manufacturing.
Relative to production from oil and gas, energy use can be reduced by 88% when plastic is produced from plastic.

High-Density Polyethylene, usually shortened to HDPE or PEHD, is a plastic polymer with flexible properties which make it ideal for a wide range of applications.

High-density polyethylene, as the name suggests, has a higher specific density than low-density polyethylene, though this difference is only marginal. What really makes the difference in the physical properties of HDPE is the lack of branching, meaning it is light with a high tensile strength. Because there is no branching the structure is more closely packed, make HDPE a linear polymer. The branching can be controlled and reduced by using specific catalysts during production.

The amount of plastic used in plastic bags has reduced by around 70% in the last 20 years thanks to the introduction of reusable canvas bags and using biodegradable materials, but the majority of bags are still produced from HDPE.

HDPE Granules that is a multi-purpose polyethylene used in diverse industrial sectors for specific applications. These HDPE Granules are sourced from reliable manufacturers and is highly appreciated by clients for superior quality.

Polyester makes up about 18% of world polymer production and is the third-most-produced polymer; polyethylene (PE) and polypropylene (PP) are first and second, respectively.

PET consists of polymerized units of the monomer ethylene terephthalate, with repeating C10H8O4 units. PET is commonly recycled, and has the number 1 as its recycling symbol.

Depending on its processing and thermal history, polyethylene terephthalate may exist both as an amorphous (transparent) and as a semi-crystalline polymer. The semicrystalline material might appear transparent (particle size < 500 nm) or opaque and white (particle size up to a few microns) depending on its crystal structure and particle size. Its monomer (bis-β-hydroxyterephthalate) can be synthesized by the esterification reaction between terephthalic acid and ethylene glycol with water as a byproduct, or by transesterification reaction between ethylene glycol and dimethyl terephthalate with methanol as a byproduct. Polymerization is through a polycondensation reaction of the monomers (done immediately after esterification/transesterification) with water as the byproduct.
