Additives for PA and PET Recycling

Mixture of functional additives for recycling PA, PET and other engineering thermoplastic waste.

Besides being environment friendly and reducing CO₂ emissions, PA, PET and other ETP recycling can be an important factor of increased profitability for compounders and processors. This should be an enticer further to world Directives such as the Waste Framework Directive objective of achieving 50% recycling by 2020 in the E.U.

However, regranulation alone is not sufficient to meet high value requirements mainly due to:

Degradation and unsuitable molecular weight
Discoloration (Thermo-oxidative damage)
Unsuitable processing behavior
Inability to match mechanical properties
Missing performance additives
Various incompatibilities

Therefore, specialty additives - such as Processing Auxiliaries, Heat and Light Stabilizers, Antioxidants, Modifiers - are required to modify the recyclate properties specifically to meet the requested properties of virgin resins.
This is particularly important as recycling can greatly increase profitability of PA and PET compounders and processors as is shown in this graph:

With a world consumption expected to reach 3,000,000 tons in the next 5 years - just for polyamide 6 and 6.6 - recycling has become critical in many aspects, with growing markets for applications with stabilized recyclates.
Such impacted nylon applications include automotive, carpets, fishing nets and lines, etc...

PET is mostly used for consumer goods packaging applications.

FAQs

What is the difference between antioxidants and UV stabilizers? ›

Antioxidant delay the formation of free radical species and hydroperoxides in polymers both during storage and conversion. UV absorbers and hindered amine stabilizers protect polymers from UV light degradation.

Know More ›

What does an antioxidant do to polymers? ›

antioxidants polymer additives are essential because they help prevent a process called oxidation. By doing so, they are able to stabilize the plastic products' qualities and slow degradation processes.

See Details ›

What is the function of heat stabilizer? ›

Heat stabilizers are used to prevent degradation of plastics by heat, especially during processing, but also in applications. For example, they are widely used in PVC compounds. Heat stabilizers act by stopping thermal oxidation or by attacking the decomposed products of oxidation (Murphy, 1999).

What are antioxidants used in plastics? ›

Phosphites are most effective during processing and protect both the polymer and the primary antioxidant. Thioesters are useful in increasing the long-term thermal stability in conjunction with phenolic antioxidants. Irgafos^® 168, Irgafos^® 126, Irganox^® PS 800 and Irganox^® PS 802 are secondary antioxidants.

Are antioxidants heat stable? ›

Natural antioxidants are resistant to heat and displayed stabilities in the following order: α-tocopherol > caffeic acid > ferulic acid > gallic acid. Subjecting chelating agents to a temperature of 110 °C for prolonged periods resulted in the following order of thermal stabilities: ascorbic acid > citric acid > EDTA.

Are antioxidants heat resistant? ›

The antioxidants below: phytic acid, ascorbic acid and PG, are the most resistant and begin their decomposition processes at temperatures between 180 and 200 °C.

What are examples of polymer antioxidants? ›

Common antioxidant polymers include essential vitamins such as retinoids, ascorbic acid, tocopherols, and polyphenolic compounds epigallocatechin gallate (EGCG), quercetin, curcumin, and resveratrol [31].

How do stabilizers work in polymers? ›

UV stabilisers absorb and dissipate the energy from UV rays as heat, typically by reversible intramolecular proton transfer. This reduces the absorption of UV rays by the polymer matrix and hence reduces the rate of weathering.

How do antioxidants stabilize themselves? ›

Antioxidants donate an electron to ROS to stabilize them, without becoming free radicals themselves. The body cells manufacture many of these antioxidants to ward off invading organisms.

Read The Full Story ›

How do UV stabilizers work? ›

The primary methods of UV stabilization involve: Absorbing or blocking UV radiation before it can reach the chromophore(s) in the polymer matrix. Deactivating or quenching the excited species generated by the UV radiation and converting them into stable, non-reactive forms.

Show Me More ›

What is the meaning of heat stabilization? ›

Heat stabilization is an additive-free preservation technology for tissue samples which stops degradation and changes immediately and permanently.

What is the thermal stabilizer for polyethylene? ›

Polyethylene is stabilized routinely by the combination of a phenolic antioxidant and a secondary stabilizer, usually a phosphite or phosphonite.

Discover More Details ›

Why are antioxidants used in polyethylene? ›

Antioxidants are key ingredients in the compounding of polyethylene and polypropylene due to the limited stability of polyolefins to high temperatures and ultraviolet (UV) light ( 12).

Tell Me More ›

What chemicals do antioxidants neutralize? ›

Antioxidants neutralize free radicals by giving up some of their own electrons. In making this sacrifice, they act as a natural "off" switch for the free radicals. This helps break a chain reaction that can affect other molecules in the cell and other cells in the body.

View Details ›

What are the most commonly used antioxidants? ›

These include the nutrient antioxidants, vitamins A, C and E, and the minerals copper, zinc and selenium. Other dietary food compounds, such as the phytochemicals in plants, are believed to have greater antioxidant effects than vitamins or minerals.

View Details ›

What is UV stabilizer? ›

Organic UV stabilizers are aromatic organic compounds that competitively absorb UV radiation and dissipate it as heat. The most commonly used UV absorbers are 2-hydroxy-benzophenone and 2-hydroxy-benzotriazole derivatives. Hydroxyphenyltriazine derivatives are also commonly used in engineering thermoplastics.
