Expancel Microspheres are small spherical particles. The microspheres consist of a polymer shell encapsulating a gas. When heated, the internal pressure from the gas increases and the thermoplastic shell softens, resulting in a dramatic increase of the volume of the microspheres. The gas remains inside the spheres.
Application :
_ Expancel Microspheres can be used as a blowing agent, weight reducer and property improver in many different applications.
_ The expansion capacity and low density along with a closed cell structure and excellent compressibility and resiliency give benefits to numerous other products. Some examples of applications where Expancel is used today are:
• Thermoplastics: e g shoe soles, profiles, hoses, sheets, cables.
• Thermosets: e g cultured marble, putties, model making board.
• Coatings: e g paint, cool roof coatings, printing ink, leather
• Board
• Adhesives
• Sealants and underbody coatings
• Technical textiles and nonwovens
• Modelling clay, food packagings and others.
