Choosing the Best Frame Material for Kids Sunglasses: TPEE vs. TR90


When it comes to selecting sunglasses for children, safety, durability, and comfort are paramount. Two popular materials often considered for kids sunglasses frames are TPEE (Thermoplastic Elastomer Ether-Ester) and TR90 (Thermoplastic Polyamide). Both materials offer distinct advantages, but which one is the best choice for your child? In this article, we will explore the definitions, properties, and ideal usage scenarios for TPEE and TR90 to help you make an informed decision.

Understanding TPEE and TR90

TPEE (Thermoplastic Elastomer Ether-Ester)

TPEE is a type of thermoplastic elastomer that combines the properties of rubber and plastic. It is known for its excellent elasticity, flexibility, and durability. TPEE is often used in applications that require a high degree of mechanical performance and resilience, such as automotive parts, industrial components, and of course, eyewear.

Key Characteristics of TPEE:

  • Flexibility: TPEE can bend and flex without breaking, making it an excellent choice for kids who might handle their sunglasses roughly.
  • Durability: Resistant to wear and tear, TPEE can withstand the rough and tumble play that kids often engage in.
  • Lightweight: TPEE is a lightweight material, ensuring that the sunglasses are comfortable for children to wear for extended periods.
  • Chemical Resistance: TPEE is resistant to various chemicals, oils, and environmental conditions, which is beneficial for maintaining the longevity of the sunglasses.

TR90 (Thermoplastic Polyamide)

TR90 is a thermoplastic polymer known for its extreme durability and flexibility. It was developed through Swiss technology to produce lightweight, strong, and flexible eyewear frames. TR90 is a preferred material for many high-end and sports eyewear brands due to its robustness and comfort.

Key Characteristics of TR90:

  • High Flexibility: TR90 frames can twist and bend without breaking, providing a high level of safety for active kids.
  • Impact Resistance: TR90 is highly resistant to impacts, making it ideal for children who are prone to dropping or knocking their sunglasses.
  • Lightweight: Like TPEE, TR90 is very lightweight, ensuring comfort during prolonged use.
  • Hypoallergenic: TR90 is hypoallergenic, which is perfect for kids with sensitive skin or allergies.

Comparative Analysis: TPEE vs. TR90 for Kids' Sunglasses

1. Flexibility and Durability

Both TPEE and TR90 offer exceptional flexibility and durability, which are crucial for kids' sunglasses. However, TR90 might have a slight edge in terms of flexibility, as it is known to withstand more extreme bending and twisting without losing its shape. This makes TR90 frames highly resistant to breakage, which is ideal for active children.

2. Weight and Comfort

Both materials are lightweight, ensuring that kids will not feel discomfort or pressure on their noses and ears. Comfort is crucial for ensuring that children keep their sunglasses on, providing consistent eye protection. In this regard, both TPEE and TR90 perform equally well.

3. Chemical and Environmental Resistance

TPEE offers excellent resistance to various chemicals and environmental factors, making it a robust choice for children who might expose their sunglasses to different conditions, such as playing at the beach or in a swimming pool. TR90, while also durable, may not offer the same level of chemical resistance as TPEE.

4. Safety and Hypoallergenic Properties

TR90's hypoallergenic properties make it a safer choice for children with sensitive skin or allergies. TPEE does not inherently possess these properties, so if your child has skin sensitivities, TR90 would be the better option.

5. Price and Availability

TPEE frames might be more cost-effective compared to TR90, which is often used in higher-end eyewear. However, the price difference can vary depending on the brand and additional features of the sunglasses.

Ideal Usage Scenarios

TPEE Sunglasses:

Ideal for younger children who need durable and flexible sunglasses that can withstand rough handling.

Suitable for use in environments where the sunglasses might be exposed to various chemicals or environmental factors, such as at the beach or poolside.

A good choice for budget-conscious parents looking for high durability without the higher price tag of TR90 frames.

TR90 Sunglasses:

Perfect for older children or teenagers who are more active and need sunglasses that can handle extreme bending and twisting.

Recommended for children with sensitive skin or allergies due to its hypoallergenic properties.

Ideal for parents willing to invest in high-end eyewear that offers exceptional durability and flexibility.

Both TPEE and TR90 are excellent materials for kids' sunglasses, each offering unique benefits. TPEE is highly flexible, durable, and resistant to environmental factors, making it great for younger kids and rougher use. TR90 offers superior flexibility, impact resistance, and hypoallergenic properties, making it ideal for active children and those with sensitive skin. Ultimately, the best choice depends on your child's specific needs and your budget. By understanding the properties and benefits of each material, you can select the perfect pair of sunglasses to protect your child's eyes while ensuring comfort and durability.
