Table of contents Polyurethane (PU) is a polymeric material with excellent physical and chemical properties and can be used to make various toy products such as stuffed and elastic ones. In other words, polyurethane and thermoplastic polyurethane are essential components to children’s and pet’s toys. Not only do they have great durability, but they also […]

Natural rubber was once the main material for sealing devices, but silicones and polyurethanes have replaced it due to their better properties. High-density polyurethane foams are now used in automotive air filters, offering benefits like elasticity, strength, and temperature resistance. These foams contain tiny bubbles formed during production, and their manufacturing involves mixing polyols and isocyanates, with curing taking place at room temperature through an exothermic reaction.

Polyurethane foam cosmetic sponges, or egg sponges, are ideal for makeup application due to their softness, bounce, and latex-free composition. They are available in polyether and polyester types, with polyether-based sponges offering better flexibility and durability. Proper cleaning is essential to avoid bacterial growth.

The chemical compounds TDI (Toluene Diisocyanate) and MDI (Methylene Diphenyl Diisocyanate) are widely used as raw materials in the production of rigid and flexible polyurethane foams. In the automotive industry, polyurethane foam is utilized in a variety of applications, bringing significant improvements to vehicles, including enhanced comfort, sound and heat insulation, safety performance, sealing, and structural integrity.
