Introduction Polyurethane (PU) adhesives are widely used in various industries due to their excellent adhesion, flexibility, and durability. However, when these adhesives come into contact with food, safety concerns arise. Ensuring that these adhesives are safe for food contact is paramount for protecting public health. This article delves into the regulatory landscape surrounding food contact...
Introduction Polyurethane (PU) adhesives have emerged as versatile materials in the medical field, offering a unique combination of mechanical strength, flexibility, and biocompatibility. Their tunable properties, achievable through careful selection of monomers and additives, make them suitable for a wide array of applications, ranging from wound closure and drug delivery to tissue engineering and implant...
Introduction Polyurethane (PU) rigid foams are widely used in various applications, including insulation, construction, and packaging, due to their excellent thermal insulation properties, high strength-to-weight ratio, and ease of processing. The formation of PU rigid foams involves two primary reactions: the reaction between isocyanate and polyol to form urethane linkages (gelation) and the reaction between...
Foaming catalysts, also known as blowing agents, are chemical compounds that play a crucial role in the production of various materials, particularly in the plastics and polymer industries. These catalysts facilitate the creation of uniform cells or pores in materials, resulting in a product that is lighter, more insulating, and often more cost-effective. This article...
