Features of urethane resins and pressure sensitive adhesives, our urethane resin products, CYABINE™We would like to introduce the series.

1.Features of urethane pressure sensitive adhesives

The main polymers of pressure sensitive adhesives used in sticker labels and tapes that we often see are generally rubber-based or designed with acrylic resins that are easy to customize. TOYOCHEM has been developing urethane resin as pressure sensitive adhesives for some time, thinking that it might be possible to create unique product designs that have never been seen before using urethane resin, which is commonly used in other fields.

What are the features of urethane resin?

  • Low odor
  • High moisture permeability
  • Low skin irritation
  • Removability

These properties are superior to general acrylic pressure sensitive adhesives.

Skin-friendly pressure sensitive adhesives
For this reason, we have taken advantage of these characteristics to develop products for healthcare, optical, and general miscellaneous goods applications, and we have a proven track record spanning several decades since their launch. In recent years, we have been manufacturing and selling urethane pressure sensitive adhesives not only domestically but also globally, and have accumulated knowledge.

Additionally, in 2020, we have utilized our unique synthesis technology to design and develop products that are environmentally friendly, such as biomass, biodegradability, and high solids, which are in demand around the world.

3.Environmentally friendly products

The newly developed urethane pressure sensitive adhesives can be labeled with the biomass mark as an environmentally friendly product.
By carefully designing urethane resins, it is possible to add new high added values related to the environment, such as ultra-high solids, biomass, and biodegradability. The newly developed product is expected to contribute to the realization of packaging formats that reduce various environmental loads.
Product name Type Solid content Characteristics
Ultra high solid pressure sensitive adhesives Slightly viscous re-peel Approximately 100% super high solid
Biomass pressure sensitive adhesives Strong adhesive - Biomass ratio 80%
Removable - Biomass ratio 10%
biodegradable pressure sensitive adhesives Strong adhesive - biodegradable,
Biomass ratio 45%
  • Biomass ratio ... Total value of CO2 while burning pressure sensitive adhesive and product life cycle.
  • Biodegradability ... Finally pressure sensitive adhesive will decompose to CO2, Water, Nitrogen, Methane by bacteria. It has tested by ISO 14855-1・Composting.

We also introduce the features of biomass and biodegradability here.
