Special edition No. 76 - Fire Resistance in Plastics 2016



This special edition of the pinfa Newsletter presents the 11th AMI “Fire Resistance in Plastics” conference, 2016, summarising presentations and illustrating with interviews of a number of conference participants.
Takeaways from the conference and networking are that there is today a large potential for development of PIN flame retardants, in developing countries as fire-safety standards are improved, and in developed countries in response to new requirements for lower smoke density and toxicity.
The conference showed the high level of innovation and the close cooperation between FR producers, polymer providers, compounders and masterbatch developers, to provide safe PIN FR solutions compatible with demanding material requirements such as processing, electrical performance, colour, weatherability, recycling, transparency and aesthetic quality.

pinfa76 Kaul

MCA Technologies

Bensi Kaul, MCA Technologies, underlined the need to look carefully at the real cost impacts of flame retardant use. In some cases, weight is critical for plastics, in others it is wall thickness. Mr. Kaul considers that organic and non-halogenated FRs are therefore advantageous, because they enable lower density.

pinfa76 YYonezawa


Yutaka Yonezawa, Adeka, presented non halogenated FRs systems for exterior applications of polyolefins, such as polypropylene. These PIN FR solutions act by intumescence, creating a protective layer which shields the polymer from heat and prevents diffusion of the pyrolysis gases necessary to feed fire.

pinfa76 RAlbach

Interview: Rolf Albach, Covestro

Rolf Albach, Covestro Germany, explained the importance of demanding fire safety standards for rigid foam building materials. Rigid polyurethane (PUR, PIR) and polycarbonate foams are increasingly used in building interiors, claddings, roofing and under-floor, to provide best-class thermal insulation, enabling important energy savings in both heating and air conditioning.
