A safer world
FOR facilitating trade by helping business gain access to global markets with safe environment and health. The focus is on Safety Testing –R&D, mechanical, weathering, flammability certification –safety, performance, system, process market access–innovation, after sales services, engineering regulation and standards.
The aim should be to provide services for product Safety and promote safe living and working environments for people by the application of Safety Science and Hazard-Based Safety Engineering; To support the production and use of products which are physically and environmentally safe by innovative and cost effective manner.
Opportunities/Challenges: Wire & Cable
The Current R&D efforts are to make available new Products offering better Cost-Performance propositions. Now with increasing importance of Regulatory Compliances in major Asian countries like: Korea, China, Japan, Turkey are focusing on:
– REACh Compliant Products
– RoHS Compliant Products
– Product complying to GHS system of Classification & Labeling.
Plasticisers can be classified as two types. A comparison of these two types is given below:
Impact of REACh (EU): Product Safety
(Health, Environmental issues related to Plasticizers)
Many studies have been conducted in recent years to evaluate plasticizers' effects on humans and on the environment, migration of phthalates, their presence in indoor air and dust, and so forth.
Only four low ortho-phthalates – di (2-ethylhexyl) phthalate (DEHP), dibutyl phthalate (DBP), diisobutyl phthalate (DIBP), and n-butyl benzyl phthalate (BBP) – have been found to have any adverse endocrine-related effects in laboratory animal studies with specific thresholds.
Data from the last 15 years show that the use of some orthophthalates such as DINP, DIDP, and DPHP has significantly increased, whereas consumption of classified orthophthalates has decreased.
Use of plasticizers such as Diisononyl cyclohexane-1,2-dicarboxylate (DINCH) and Dioctyl terephthalate (DOTP) has also increased, reflecting industry commitment to developing new and safe products through research and innovation.

What can be Done to Make products safer?
Product safety is not only linked to the product itself but also depends on the way the product is used in specific applications. This is why the use of plasticizers is strictly regulated and the European legislation clearly defines the specific use of substances in all different applications, from medical devices to cosmetics, building applications to toys.
To enhance the safety of plasticizers, it is, therefore, necessary to have a clear and consistent regulatory framework that enables industries to invest, research, innovate, and grow.
Another interesting aspect is to see how close plasticizers are to people in their daily life, and how these substances can improve their lifestyle with myriad benefits to their health and the environment. Let's just think about medical applications, for example, or innovative and sustainable buildings and constructions. This is why the misconceptions sometimes raised by the media or by inaccurate studies must be addressed by providing scientific data and reliable information about plasticizers and their safe use.
Authorization has been recommended for DEHP and DBP on the basis of adequate control; no authorization request has been made for DIBP and BBP, and these substances cannot continue to be used in Europe as of February 2015 for REACH-related applications.
At the end of 2014, the European Chemicals Agency (ECHA) Member States Committee concluded that DEHP is an endocrine disruptor of equivalent level of concern for its environmental properties. The science on DEHP does not support such a conclusion, as the weight of evidence shows that DEHP does not cause adverse endocrine effects in fish and other aquatic organisms.
All other plasticizers have not been classified for any adverse health effects and do not cause adverse effects by means of an endocrine mechanism. Hence they are not endocrine disruptors. This has been confirmed by the ECHA after a four-year re- evaluation of the hazard and exposure data for two of the most widely used plasticizers, Diisononyl phthalate (DINP) and Diisodecyl phthalate (DIDP), including extensive reproductive and endocrine data.

Impact of REACh (EU): Misconception
Unfortunately, there are many misconceptions related to plasticizers – for example, about phthalates “leaching out” and “easily dispersing/gassing out” from PVC products.
This is unlikely to happen unless very abrasive detergents or solvents are used or if the articulates are exposed to extreme conditions for an exceptionally long time. Plasticizers do not readily migrate /leach into the environment from items because they are physically bound within the PVC matrix. If they could readily migrate, flexible PVC would not remain flexible and perform as intended.
Impact of REACh (EU): Misconception
Other misconceptions are linked to indoor air and dust; in this case, it is very important to emphasize that the presence of flexible PVC particles in house dust does not pose any risks to human health. Recent scientific studies have in fact concluded that household dust does not correlate to human exposure levels for phthalates and is not an indicator of indoor air quality.
The new generation Plasticizers must meet the “Increasing challenging Regulatory, Performance and Commercial constraints".
The New Generation Polymer compounds call for safer and greener cable solutions to meet "Innovative building cable solutions to ensure safety, performance and environmental friendliness”.
Wire & Cable Compounds
Wires and Cables are present in our everyday life. Energy and data are transmitted by cables. Polymer compounds used for electrical insulation of conductors and mechanical protection of cable constructions from ignition and flame spread.
Different technologies exist to produce cable compounds. The best choice for a certain case depends on the property profile of final product as well as on the applicable base polymers, the additives and the available compounding and extrusion technology.
All types of polyethylene are cross linked like LDPE, LLDPE, HDPE, MDPE.
Branch structure is more suitable for cross linking.
Cross linking leads to the formation of three dimensional network structure.
Cross linking can be done by different process.
