Non-isocyanate polyurethanes (NIPUs) represent a significant advancement in polymer materials, offering a safer and more sustainable alternative to traditional polyurethanes. Polyurethanes represent a significant class of polymer products. With an estimated annual market size of around 20 million tons, polyurethanes are primarily used in...
For years, the quest for safer and more sustainable materials has driven innovation in the chemical industry. One significant breakthrough is the development of bisphenol-free epoxy resins. These resins address the environmental and health concerns associated with traditional bisphenol-based compounds, offering a safer alternative for...
As part of its development activities, SPECIFIC POLYMERS places a central focus on establishing an eco-responsible supply chain to ensure the production of some of its references in a biobased grade. For several years, SPECIFIC POLYMERS has been offering epoxy resins prepared from renewable resources. Notably,...
March 2023 | In the course of the development of renewable Isocyanate-free Poly(urethane)s, SPECIFC POLYMERS offers its range of sustainable cyclocarbonates building-blocks. Among them, three references: SP-68-010, SP-68-015 and SP-68-020 are di- or (...
On June 15th, Alain GRAILLOT – COO of SPECIFIC POLYMERS participated to AIRPOXY Public Workshop. AIRPOXY Project is a H2020 Project led by CIDETEC in which thermoformable, repairable, and bondable smart ...
At first, developed during the second World War II as an alternative for rubber, Polyurethane (PU) has been largely extended in the 50’s as elastomers, coatings, foams and adhesives (Figure 1).1 Today, the continuous improvements of this chemistry and its outstanding [...
Recent attention has been paid to explore new recycling strategies reducing additional treatments to convert the rigid networks into viscolelastic liquids. For example, as described by K. Fukuda and coworkers[11], imine dynamic exchanges can combine both associative (transimination) [...
These last decades, photopolymerization has seen an important development, especially in adhesive and coating applications and with the emergence of the 3D printing field. This process relies on the formation of a crosslinked material from monomers/oligomers in liquid state, initiated by (...
Thermosensitive polymers are a class of “smart” materials that have the ability to respond to a change in temperature. Such polymers are uncommon as they are soluble in water at low temperature and become non-soluble when increasing the temperature (...
Fibre reinforced thermoset composites are attractive materials for high demand sectors, such as the motor industry and construction, due to their lightweight and excellent mechanical properties. However, the lack of re-processability and difficulty in repairing and recycling significantly increases the overall material cost and causes...
