  • BASF Light Stabilizers for Synthetic Fibers

    BASF Light Stabilizers for Synthetic Fibers

    Today, more than half of the 80 million metric tons of fibers consumed per annum are synthetic. Synthetic fibers are largely used in technical textiles and fabrics to meet all kind of mechanical, aesthetic and durability requirements.

    Synthetic fibers continue their rapid growth in a variety of end use applications such as nonwoven for consumer goods, construction materials, textiles for automotive as well as mono-filaments for artificial grass used in sport fields or landscaping.
    Polypropylene is a very important material used in BCF (bulk continuous fiber) processing, nonwoven fibers spinning or the associated weaved tapes. Polyethylene and Polyamide mono-filaments as well as polyester are other important polymers for technical synthetic fibers.

    Technical man-made fibers, initially developed and produced in Western countries to compensate for the declining textile clothing activities, are now expanding worldwide fueled by the demand of the rising middle-class population.

    UV and Light stabilizers to protect synthetic fibers from degradation

    Synthetic fibers are subject to thermo- and photooxidative degradation during polymer processing, spinning and later service life. Fibers used in applications such as artificial turf, barrier membranes or carpets and flooring have to withstand very harsh climate conditions, including prolonged exposure to UV light and environmental pollution or contaminants. Very demanding long-term durability is essential in some end applications, such as construction and automotive.

    Irganox® antioxidants, Chimassorb® and Tinuvin® Light stabilizers protect the fiber from adverse thermal and UV aging such as discoloration and degradation.

  • BASF to Construct Specialty Amines Plant in Nanjing, China

    BASF to Construct Specialty Amines Plant in Nanjing, China

    BASF will build a new specialty amines plant at its existing wholly owned site in Nanjing Chemical Industry Park in China. The new multi-product plant can manufacture 21,000 metric tons per year and further extends BASF’s amines portfolio at the specialty amines complex in Nanjing.

    Start-up Planned in 2019

    BASF’s amines portfolio at the specialty amines complex in Nanjing


    The plant is scheduled to come on stream in 2019 and will mainly produce 1,2-Propylenediamine (1,2-PDA), n-Octylamine (n-OA) and Polyetheramine (PEA).

    “BASF offers a wide range of amines globally, and this investment reflects our continued commitment to meeting the growing market demand in Asia Pacific,” said Stefan Blank, President, BASF Intermediates division. “Building on decades of experience in developing and manufacturing amines, this new plant will further strengthen our global leadership in these versatile intermediate products.”

    Increasing Asia Pacific Demand for Specialty Amines

    “This investment will help us to meet the increasing Asia Pacific demand for specialty amines used as intermediates in a diverse range of industries and applications, such as epoxy formulations, crop protection agents, spandex and biocides for the coatings industry,” said Narayan Krishnamohan, Senior Vice President, Intermediates Asia Pacific, BASF. “Through this expansion, we will be able to better serve our customers in Asia Pacific with steady and timely supply of quality products.”

    BASF also has manufacturing capacities for both 1,2-PDA and n-OA at its Ludwigshafen Verbund site in Germany. Manufacturing plants for PEA are located at BASF sites in Ludwigshafen, Germany, Geismar, USA and Nanjing, China.

    The main products of the new plant include:

    1,2-Propylendiamine (1,2-PDA) is an essential ingredient to produce elastic fibers. It is also used as a building block in the manufacture of pharmaceuticals, crop protection agents, colorants, textile auxiliaries, pigments and optical brighteners. Furthermore, it is used as a corrosion inhibitor in surface treatment products.

    N-Octylamine (n-OA) is used as a chemical intermediate for the synthesis of antimicrobial and biocidal agents.

    Polyetheramines (PEA) are chemical intermediates used, for example, to produce polyurea coatings, adhesives and plastics. PEA is also used as a curing agent in epoxy resin systems for the production of blades for wind energy plants. BASF offers PEA under its Baxxodur® brand.

  • Solvay to Sell its Polyamides Business to BASF

    Solvay to Sell its Polyamides Business to BASF

    Transformation to Multi-specialty Chemical Company

    “Solvay’s planned divestment of Polyamides marks a tipping point in the profound transformation journey we began four years ago. Successful completion of this transaction will further reinforce Solvay as a multi-specialty chemical group, delivering superior growth and sustainable value,»said Jean-Pierre Clamadieu, CEO of Solvay.

    Strengthen BASF’s Engineering Plastics Portfolio

     

    Applications of Polyamides

    BASF is a strategic investor for Polyamides which complements both its business as well as its global presence. Solvay and BASF share the same commitment to best-in- class health, safety and environment standards on their sites.

    Polyamides have grown profitability over the past years. As an integrated player, its activities range from upstream intermediates and polymers, to downstream with the development of high value-added engineering plastics. The transaction covers Solvay’s upstream and downstream polyamides business in Europe, North America and Asia, as well as the downstream engineering plastics business in Latin America and involves around 2,400 Solvay employees. Solvay will retain its upstream intermediates and downstream textile polyamide business in Latin America.

    Under the proposed terms of the agreement, the transaction is based on an enterprise value of €1.6 billion, which represents ~8 EBITDA of 2016 and ~7 EBITDA in the last twelve months. The expected net cash proceeds are estimated to be around €1.1 billion. Taking into account the financial liabilities of about €0.2bn to be transferred to the acquirer, the net financial position of the Group will improve by about €1.3bn.

    The polyamide business planned to be divested will be reclassified to assets and liabilities held for sale and discontinued operations at the end of September. As a result of the discontinuation, the retained Latin American polyamide business will incur an impairment of close to €(100) million to be booked at the end of September. This impairment is expected to be more than compensated by the capital gain on the transaction at the closing.

    The execution of definitive agreements is expected in the coming months following consultation with the relevant social bodies. Solvay and BASF aim to close the transaction in the third quarter of 2018, after customary regulatory approvals have been obtained and the formal consent of a Joint Venture partner has been received. The partner has already committed to grant its consent subject to the delivery of definitive documents with BASF.
