Highest-Quality TPUs for Dental and Orthodontic Devices

The medical and cosmetic dental market has experienced expansive growth in the last decade, spurring equal growth in market innovation. Well-known materials like thermoplastic polyurethanes (TPUs) are increasingly finding new uses as clear dental aligners, retainers, mouth guards and other dental and orthodontic products.

Lubrizol is the oldest and one of the largest manufacturers of TPU in the world and Lubrizol Life Science Health is a total material solutions provider for dental device manufacturers. Our Isoplast® ETPU and Pellethane® TPU are the materials of choice for many dental device applications.

Isoplast® ETPU: Best Single Polymer for Consistent Performance and Manufacturability

Isoplast engineered thermoplastic polyurethanes (ETPUs) are the top-tier materials in the dental space. With a unique combination of properties, they provide predictable outcomes, patient comfort and processability. Isoplast ETPUs have high tensile strength and elongation at yield, combining the toughness and dimensional stability of amorphous resins with the chemical resistance of crystalline materials. 

Qualities that make Isoplast ETPU ideal for dental applications:

  • Medical-grade
  • Rigidity
  • Toughness
  • Resistance to stress-relaxation
  • Higher restorative force
  • Optical clarity
  • Chemical resistance (resists cracking)
  • Consistent quality
  • Processable via extrusion and secondary heat forming

For ease of manufacturability and speed to market, Isoplast ETPU is the best single material for invisible aligner and retainer applications, meeting all requirements and consistently outperforming other traditionally used commodity rigid plastics. 

Pellethane® TPU: Ideal Polymer for Enhancing Patient Outcomes

Pellethane thermoplastic polyurethanes (TPUs) offer a range of properties for medical and healthcare products. Pellethane is known for its flexibility, strength and is available in a range of durometer/modulus options. Pellethane is an excellent material choice for dental devices with a multiple-polymer design. It is bondable and processable with other thermoplastics, including Isoplast to achieve desired patient outcomes.

Qualities that make Pellethane ideal for dental applications:

  • Medical-grade
  • Good elastic recovery
  • Flexibility
  • Optical clarity
  • Abrasion resistance
  • Tear resistance
  • Good stain resistance
  • Compatibility with antimicrobial agents and other oral care ingredients
  • Consistent quality
