Specialty chemical companies are bringing their advanced polymer product innovations into the market to enhanced Recent developments in this sector involved Devan Chemicals’ special “cool comfort” technology that efficiently whisks away sweat for sportswear and workout apparel. Saudi Basic Industries Corporation (SABIC) bared an advanced new polypropolene (PP) resin material that makes nonwoven fabrics lighter and breathable. For consumers increasingly concerned about the safety aspects of materials used for dayto- day products, ELIX Polymers has dveloped a fresh line of ABS products that satisfies strict requirements coupled with reinforced standards applied during the production of the polymer products.
Technology ensures comfort
Devan Chemicals takes cue from Mother Nature for inspiration for its Moov&Cool’s “cool comfort” technology from the thermoregulation mechanism of plant leaves. Plants use small pore-like openings (stomata) on the bottom of their leaves which open and close depending on the environment they are exposed to. This allows them to manage the water reservoir in the leaves and hence their thermoregulation.
Like the stomata action of the leaves on plants, Moov&Cool fabrics have pore-like openings that effectively manage sweat evaporation in a smart way. Whereas other technologies count on wind to help evaporate sweat to create cool skin sensation, Moov&Cool uses superfluous heat produced by the body during the sports performance or aerobic activities to lower the body core temperature.
In addition to a fast absorption of sweat, the cooling technology helps to manage sweat evaporation in a balanced way. Moov&Cool is a patented Devan polymer technology that combines durable heat absorption capacity, thermo-conductivity and a unique, balanced moisture transfer system to give the wearer a cool comfortable feeling. Devan claims its technology is truly unique. The cooling effect of the high-tech sportswear remains even when the wind speed is reduced, which making Moov&Cool clothing also suitable for indoor sports and activities. The topical treatment for textiles has been brought to life in an effort to boost the performances of professional athletes, and to enhance comfort for recreational athletes.
SABIC PP 514M12 delivers enhanced properties in melt-brown fibres for non-woven fabrics
This advance sportswear technology is not only useful in hot climates, but also in temperate climates where the cold comes in the picture as when Moov&Cool is exposed to colder conditions, the pore-like openings in the polymeric layer are more closed, trapping heat between the body and the fabric. The company collaborated with the University of Leuven (Belgium) and the Bakala Academy to evaluate and prove the finishing technology. According to Devan, the first results look promising as they have seen an effect on heart rate and lactate levels. Furthermore, the first test results also highlighted a decrease in core temperature of around 0.4°C. The chemical company looks to further continue testing in order to evaluate the impact of Moov&Cool when applied to different fibre types and fabric structures where performance intensity may play a major role in the protection required.
Enhanced properties for the personal hygiene market
The global market for personal hygiene products is expected to witness substantial growth over the coming years owing to the growing disposable income of consumers. This rapid growth poses a challenge to chemical companies to meet the high level of consumer needs in this market. SABIC rises up to meet this challenge with its new PP resin product, SABIC PP 514M12, designed to deliver enhanced properties in melt-brown fibres for non-woven fabrics.
Utilising phthalate-free and odour-free technology, SABIC PP 514M12 nonwoven web materials are developed to combine high barrier properties and absorption with breathability in thin and lightweight high-performance fabrics. SABIC melt-blown fibres exhibit enhanced conformability and reduced material consumption, and manifest high levels of drawability, spinnability and uniformity.
The melt-blown fibres made from SABIC 514M12 polymer exhibit a final melt flow rate of >1,000 g/10 min. This characteristic opens unique potential manufacturing possibilities for very lightweight and thin nonwovens aiming to provide improved air permeability and wearability at the same time maintaining optimum barrier property. The potential improved absorption and barrier performance of fabrics based on SABIC’s PP 514M12 polymer has also been underscored in hydrostatic head tests, a frequent requirement for specific configurations of spun-bond/melt-blown/spun-bond (SMS) nonwovens for hygiene applications.
ELIX Polymers CC grade offer additional guarantees on regulatory compliance.
Moreover, SABIC’s latest polymer aims to provide high purity and enhanced customer convenience over incumbent melt blown resins and benchmark blends. The polymer resin is supplied in regular pellet form, which facilitates handling, storage and use. The PP material can serve a wide range of potential end-uses in personal hygiene applications and other market segments. SABIC PP 514M12 is the first grade of a new family of high-flow resin compounds which SABIC started to develop only two years ago, and is expected to be commercially available by end of 2018.
Safety in consumer products
ELIX Polymers is releasing a new line of ABS products under the brand name Chemical Compliance (CC). Applications for this new ABS product line include toys, cosmetic containers, and products that come into contact with food. The aim of the new range is to satisfy the requirements of consumers increasingly concerned about the safety aspects of materials that day-to-day products are made from. Reinforced standards applied during production of CC grades will enable ELIX to offer additional guarantees on regulatory compliance during the lifetime of finished products.
The CC line comes with a package of extended services that will facilitate OEMs in the fulfillment of their product verification and stewardship processes. These services include the provision of documents indicating regulatory compliance for different national and international sectors. These also include the application to final parts of results from additional tests on the safety of the material in contact with food. ELIX will also conduct product quality and safety tests based on the requirements to which OEMs may be subject.
Customers can choose among the CC line according to their needs as ELIX offers various grades formulated for individual applications. Two of many offerings in the new CC line are ELIX ABS P2H-CC and ELIX ABS P3H-CC. Based on each requirement, these ELIX injection moulding grades are easy to process and have a high level of brightness as well as intense colours. All the ABS products are backed up by a service that will facilitate the product stewardship tasks for the OEMs.
With this new product line and consulting service, ELIX Polymers takes care of a large portion of the work involved in verifying and guaranteeing that not only its ABS materials, but also all the components present in its materials – pigments and additives for example – are compliant with the law.
Single-dose coffeemakers are one of the product applications ELIX is looking into with the advent of the new CC grades. Launching a new machine onto the market requires a large number of tests to be performed on component materials to guarantee compliance with food safety laws. Such tests can take a considerable amount of time and resources to carry out, with possible effects on the course of development projects.
