Sixth International Conference on Composites In Fire

9 – 10 June 2011, Newcastle University,  UK

The Composites in Fire conferences exist to transfer understanding, technology and research results from major programmes from three continents, Europe, USA and Australia, to industry.

Since CIF-5, which was held in 2008, substantial progress has taken place in testing and modelling the problem of the fire resistance of composite structures. There have also been important changes in the methods used to achieve low heat release and improved fire resistance. Important research has also taken place to fairly compare the fire behaviour of composites with other lightweight construction materials, including aluminium. It is the purpose of CIF-6 to report this progress and transfer the technologies and techniques developed to industry. The programme will include ‘Fire Resistance and Fire Reaction in Composites: New Developments’; ‘Technology Transfer: Marine and Aerospace’; ‘Multi-Scale Modelling of Materials and Structures in Fire’; ‘Materials Selection and Materials Comparisons’.

Sustainable innovations from Clariant at Techtextil

Under the theme ‘Performance that protects Protection that performs’ and at an impressive stand with a striking cubist design Clariant is showcasing its latest innovative and sustainable solutions for the technical textiles sector at this year’s Techtextil, Frankfurt, May 24-26, 2011, Stand 3.0 B33.
In many instances, technical textiles are about providing protection – whether for people, vehicles, buildings or the environment and Clariant has developed advanced solutions to provide exactly what’s needed when it’s needed, be it strength, resiliency, antimicrobial protection, fire retardancy, repellency or barrier performance.

Highlights at Booth 3.0 B33 for the Protech, Medtech, Mobiltech and Hometech categories include the many new products presented here below. They complete an already unique portfolio and confirm Clariant as a matchless system supplier of solutions that are especially designed for the final application.

Protech
Visitors at the show will experience why Clariant solutions are ‘the safeguard you can rely on’ for repellency, flame retardancy and antibacterial protection.

Very easy to handle in processing, Nuva N products impart long-lasting soil repellency and release effects, while being non-sensitive in respect of their compatibility to other finishing chemicals.

Specifically for manufacturers of protective clothing, new PFOA-free, C6 based Nuva N4547 provides a highly durable soil release finish with good oil repellency, most notably on cellulosic fabrics.

Protective material also needs to be flame retardant and Clariant’s Pekoflam MSP liq is a top performer here. It is less hygroscopic than competing products and, a very good water soaking resistance can be achieved by thermoset treatments at 160-170°C. Pekoflam MSP is a listed Oeko-Tex 100 Class II product.

Medtech
Clariant offers products that are especially designed to help create ‘a barrier you can trust, where cleanliness is a must’, through benefits such as strength and flexibility, alcohol and blood repellency and antibacterial protection.

A number of benefits can be provided to medical and hygienic disposables, meanwhile, with Nuva N2155 liq, a C6 based fluoro polymer with non detectable PFOA: This is characterised by very good alcohol and blood repellence, with a fast curing profile, even at low temperatures, making it suitable for sensitive fibers such as polypropylene. The fastness of Nuva N2155 liq provides an excellent repellency performance and the non-ionic nature of the product has an improved compatibility with the binders employed in such disposables.

Appretan NF liq, meanwhile, imparts very interesting properties on nonwovens for medical and hygiene applications, notably alcohol resistance and wet elongation. The styrene/acrylate is soft and self crosslinking, even though being formaldehyde free and hydrophobic. This interesting performance also fits nicely into pigment printing concepts.

Alternative Flame Retardants

European Brominated Flame Retardant Industry Panel (EBFRIP): For some applications it is possible to substitute existing flame retardants with alternatives. However, EBFRIP supports the objectives of the REACH legislation, in which substitution should be considered only when a substance is subject to restrictions, and when an alternative is available which has also been subject to registration and evaluation, and found to present a more favourable risk profile.

For Deca-BDE, alternatives exist for virtually all applications. However, as Deca-BDE has not been shown to present significant risks to human health or the environment, its replacement by other flame retardants whose potential impacts on human health and the environment are far less understood is not warranted.

For TBBPA, no risks have been identified for reactive use (in printed circuit boards), and to date there is no readily available alternative flame retardant.

For HBCD, currently there are no technically and commercially feasible alternatives for EPS and XPS applications, demonstrated to have more favourable risk profiles, despite intensive research.

HBCD is now officially subject to the Authorization procedure under REACH

On 18 February, the amended Annex XIV of substances for Authorization under REACH was published in the Official Journal and will enter into force on 21st February. Consequently, HBCD – which is included in the Annex – is now officially subject to the Authorization1 procedure under REACH, along with five other substances.  Read more (ICL)

FireBlock fire resistant resins

FireBlock fire resistant resins and gelcoats gained Total Group company Cray Valley an innovation award in the material category at the recent 2011 JEC Composites show in Paris.
FireBlock is labelled a Total Ecosolutions product, due to the reduced energy consumption and reduced greenhouse gas emissions in its production and use, as compared to standard fire retardant composites used in railway rolling stock. The Total Ecosolutions programme is aimed at developing products and services to help both businesses and consumers reduce their energy use and their environmental footprint. Introduced in 2009, the programme today encompasses 16 different products and services and a further 16 other products and services are reaching the final stage before labelling. According to the company’s estimates, based on a comparison with reference products and services available in the European market and offering an equivalent outcome for the customer in March 2011, the use of all the products and services in the Total Ecosolutions lineup as replacements for conventional products, would avoid the emission of nearly 558,000 metric tons of CO2 equivalent per year – the amount emitted by 55,800 European Union residents in one year.

New Solutions from PolyOne: OnFlex™ Flame-retardant

PolyOne Corporation, a premier global provider of specialized polymer materials, services and solutions, will feature new innovations during Chinaplas 2011. Held annually, Chinaplas is Asia’s largest plastics industry trade show.

  • OnFlex™ Flame-retardant, Non-phthalate Thermoplastic Elastomers help processors and manufacturers meet sustainability goals and maximize consumer appeal. Developed in response to consumer demand for more eco-conscious alternatives for wire and cable jacketing, insulation and connectors, these formulations provide exceptional visual and tactile aesthetics in a non-plasticized solution.

Chinaplas 2011 will be held in Guangzhou, China from May 17 to 21. More than 80,000 visitors from 35 countries are expected to participate. PolyOne will exhibit in hall 11.2, booth J41. (Source: Click here)
