Developing the Coatable and Highly-Stretchable Hot Melt Material “StretchMelt™”

Sekisui Fuller Company, Ltd. (hereinafter referred to as “Sekisui Fuller,” the president and representative director is Ichiro Arai), a joint venture between SEKISUI CHEMICAL CO., LTD. (the president and representative director is Teiji Koge) and H.B. Fuller Company (headquartered in Minnesota, USA, the president and CEO is Jim Owens), and NAGASE & CO., LTD. (hereinafter referred to as NAGASE, the president and representative director is Kenji Asakura) have jointly developed “StretchMelt™ ” a highly-stretchable hot melt material that can be coated using a general purpose applicator, for the first time in Japan.*1 While stretch materials are used in many products, such as clothing and hygiene products, the demand for harmonization of coating performance, texture, and the handling ability of the material, has been growing. In response to this situation, both NAGASE, having knowledge of market needs and manufacturing processes, and Sekisui Fuller, with its hot melt formulation technology it has cultivated over the years in a variety of sectors, have developed a material with higher stretchability and value that brings freedom to product designs. We will commence mass-production and sales at the beginning of 2019 and will expand its application to the clothing and hygiene product sectors, including disposable diapers and masks, as well as other industry sectors, taking advantage of its features, such as coatability and high stretchability.

1. Hot Melt Material

A hot melt material is a solventless petrochemical product which is widely used in the world mainly as an industrial adhesive. Sekisui Fuller has the top market share for hot melt adhesives in Japan.*2

2. Features/applications of StretchMelt™

StretchMelt™ is an innovative stretch material developed by using Sekisui Fuller’s ingenious hot melt design and formulation technologies, based on the concept of coatable stretch material that can be used for a variety of applications.
StretchMelt™ is a coatable stretch material whose shape, coating position and coating pattern can be freely determined, and its future use in a variety of applications and sectors can be expected. Especially in the hygiene product sector, such as disposable diapers and masks, stretchable products can easily be created with non-woven fabric, using the technological capabilities we have cultivated over the years. We believe that the range of applications in other sectors is wide as well, because it can be processed into any shape you want.
