Sebacic Oman plans to build $250m bio-based nylon project in Duqm

Sebacic Oman SAOC plans to build a bio-based nylon project as forward integration of its soon-to-be-commissioned sebacic acid project in the Duqm free zone.biobased nylon

The 10,000 tonne per annum-capacity project, which is expected to produce two grades of bio-nylon (nylon 6-10 and nylon 10-10), will have an estimated capital expenditure of $250 million.


Bio-Polyamide, Specialty Polyamide and Precursors Market to Grow in the Coming Years

Undecanoic acid and sebacic acid derived from castor oil areamong the most dominant raw materials used in the production of bio based polyamide. Owing to the eco logical benefits, bio based polyamides are gaining acceptance and are anticipated to be the fastest growing product segment during the forecast period.Sebacic_acid_3D_ball

Asia Pacific dominates the global demand for bio-polyamide, specialty polyamide andprecursors and the trend is expected to continue during the forecast period.


Tierra Introduces New 100% Bio-based Jacket

Tierra, a Swedish outdoor apparel brand, committed to sustainability and lowering environmental impact, is introducing its new Deterra Jacket, a technical jacket that is fully free from fossil based material and uses exclusively bio-based elements.tierra_log_x2

The exterior fabric is made with Evo by Fulgar, a polyamide produced from castor oil, while the padding is in wool from German sheep and Tencel yarn derived from wood cellulose. Finally, the buttons are in corozo nut from the Tagua palm, and the hood fastens with a simple knot instead of the usual plastic stopper. The jacket is available in two versions, Deterra Hood Jacket and Deterra Shirt Jacket.


Biobased PA 6.10 Compounds Added to Portfolio of BioFed

German biodegradable and biobased plastics producer Bio-Fed  has added renewable resource-based polyamide compounds, the “MVera ECS” products, to its portfolio. The main focus of Bio-Fed is on compostable and biodegradable plastic compounds for film applications as well as injection

The new PA 6.10 fulfils the standard definition of a bioplastic since it is made up of approximately 60% renewable resources. Castor oil, derived from the seeds of the plant Ricinuns communis, forms the basis of sebacic acid, which is the product’s renewable raw material content.


Arkema Launches Polyamide Processed from Castor Oil

ArkemaArkema has launched a new biosourced polyamide 6.10 range called Rilan S, partially processed from castor oil. The polyamide has been manufactured at Arkema’s Zhangjiagang facility in China

Rilan S is an alternative to long-chain polyamides and PA6/PA6.6; it closes the gap between long-chain polyamides and PA6/PA6.6. The various Rilan S grades already available find applications in the field of transport, sports and electronics.


100% Biobased Polymer as Food Contact Substance

Evonik, German-based specialty chemicals company, has received approval for its foodmq1 contact substance ‘VESTAMID Terra DS16 natural’. VESTAMID Terra DS16 is a biobased polymer belonging to the family of PA1010 polyamides.

The polymer is based on renewable feedstock. The starting material is the castor bean and its oil derivatives. VESTAMID Terra DS is based on polyamide 1010, which is the polycondensation product of 1, 10-decamethylene diamine (D) and 1, 10-decanedoic diacid (sebacic acid – S). Both of these are derived from castor oil, which means that Terra DS is 100% Bio based.

Another polymer named Terra HS, based on polyamide 610, contains polycondensation product of 1, 6-hexamethylene diamine (H) and 1, 10-decanedoic diacid (sebacic acid – S) and is 63% biobased. Terra HS is already being approved in the EU and USA for food contact with non-alcoholic food materials.

Microorganisms for Bio-Based Nylon Intermediates

Genomatic, a U.S. Biotech company, bacteriahas planned to develop technologies for the production of bio-based nylon intermediates- hexamethylenediamine, caprolactam and adipic acid. Approximately, revenue of $18 billion is bagged by these three chemicals every year.

The company has been involved in a several experiments, to study the

production of nylon intermediates by various microorganisms. The research team of Genomatic is basically trying to demonstrate the metabolic pathways, efficient methods of production and recovery of these intermediates. Source

Castor oil based nylon has a relatively low density for a polyamide, good low temperature impact strength and good dimensional stability. Know more on the nylon intermediates from castor oil

Royal DSM’s Develops Crankshaft Cover from Castor Polyamides

In September 2013, Royal DSM, together with its automotive component specialist partner KACO, has developed a lightweight multi-functional crankshaft cover in EcoPaXX, DSM’s bio-based polyamide 410, for the latest generation of diesel engines developed by the Volkswagen Group. EcoPaXX, a bio-based, high-performance long-chain polyamide, is made mainly from tropical castor beans.

This EcoPaXX cover incorporates integral seals in PTFE and liquid silicon rubber (LSR), as well as various metal inserts. It will be used on Volkswagen’s new MDB modular diesel engine platform, implemented across its Audi, Seat, Škoda and VW brands.

Compared with covers made in aluminum, system costs for the EcoPaXX cover are considerably lower, due in part to the use of an integrated, fully automated production cell for the component at KACO. Weight has been reduced considerably too, since the EcoPaXX grade is 45% less dense than aluminum.

The development represents a step forward in terms of sustainability, from material production to the vehicle on the road. DSM’s EcoPaXX polyamide 410 is 70% derived from renewable resources, and the polymer is certified 100% carbon neutral from cradle to gate.

Bio-Polyamides: Where Do They Come From?

Article retrieved from

Bio-polyamides have been available commercially since the first half of the 20thCentury, when Rilsan®11 was first introduced. Since then, other partly or fully bio-sourced polyamides have been commercialized for a range of applications. This blog post explains how organic chemistry and catalysis can be critical to converting renewable raw materials into technologically valuable polymers.

Both 11-aminoundecanoic acid and sebacic acid are products from chemical conversion of ricinoleic acid, the major fatty acid component of castor oil.Castor oil is hydrolyzed to give ricinoleic acid and glycerol, which are separated. High temperature treatment of the methyl ester of ricinoleic acid produces 11-undecanelic acid and heptanal4. Bromination of the double bond of 11-undecalenic acid followed by reaction with ammonia gives 11-aminoundecanoic acid, the monomer used to make PA 11 (Rilsan® 11).

Sebacic acid is produced commercially by “fusing” ricinoleic acid with alkali (reacting at high temperature with sodium or potassium hydroxide). This chemistry has been known for decades and has been optimized significantly.

At present, there is no large-scale commercial source of bio-based 1,12-dodecanedioic acid, although potential routes have been reported. Polyamides produced from this monomer rely on 1,12-dodecanedioic acid prepared from petroleum-derived butadiene, so such polymers are only partially bio-sourced, assuming that the diamine component is derived from renewable sources.

ARKEMA and Addiplast Joins to Develop New Polyamide Compounds

As the world’s sole chemicals manufacturer to offer the entire long chain polyamides range, polyamide 12 as well as biosourced polyamides PA11and PA10 derived from castor oil, Arkema is the leading player in the production of specialty polyamides.

Addiplast has emerged both in France and in Europe as one of the leaders in the design of technical compounds and polymers derived from polyamides, polyolefins and polycarbonates. With its expertise in the design of these materials and related processes, Addiplast became a partner of Arkema in the early 2000s.

Through this strengthened partnership, Addiplast will develop from biosourced polyamides (Rilsan® PA 11 and Hiprolon® PA 6-10, PA 10-10, PA 10-12) and other specialty long chain polyamides (Rilsamid® PA12, Hiprolon® PA 6-12) supplied by Arkema, a new range of high-end materials and compounds for injection molding. These compounds are designed for high added value applications requiring specific performances.

Marketed under the trade names Addinyl® (polyamides of fossil origin) and Addibio® Renew (biosourced polymers), these solutions fulfil demanding specification requirements in terms of mechanical strength and/or chemical resistance. They will serve on the European market diversified segments, including automotive, electronics, sports and leisure, new energies and new technologies.
