An elastomer is a polymer with the property of viscoelasticity (colloquially "elasticity"), generally having notably low Young's modulus and high yield strain compared with other materials. The term, which is derived from elastic polymer, is often used interchangeably with the term rubber, although the latter is preferred when referring to vulcanisates. Each of the monomers which link to form the polymer is usually made of carbon, hydrogen, oxygen and/or silicon. Elastomers are amorphous polymers existing above their glass transition temperature, so that considerable segmental motion is possible. At ambient temperatures rubbers are thus relatively soft (E~3MPa) and deformable. Their primary uses are for seals, adhesives and molded flexible parts.

Applications:

  • Auto interior modifier for excellent feel
  • Wire and cable coatings with enhanced physical properties
  • Footwear foams that are light and deliver excellent resiliency and cushioning to the shoe
  • Molded goods such as toys or other household items
  • Injection molding with better thermal stability and heat resistance
  • Improved impact resistance and low temperature performance in thermoplastic polyolefins, such as TPO roofing and automotive bumper fascia

Characteristics:

  • Excellent impact resistance
  • Easy colorability
  • Tough yet flexible
  • Low density and light weight
  • Easy mixing, forming and processing on plastic or rubber equipment
  • Recyclable for in-process scrap re-use
  • Excellent melt strength and processability
  • Lower shrinkage
