Why Choose PES and TPU Based Heat Transfer Reflective Tape

YSM heat transfer reflective tape factory mainly uses two kinds of substrates: polyester (PES) and thermoplastic polyurethane (TPU).

Material property comparison: PES and TPU

Polyester (PES) substrate

• High temperature and aging resistance
  PES substrate has excellent high temperature resistance and aging resistance, and can maintain stable performance over a wide temperature range. This feature makes PES suitable for reflective applications in outdoor and high temperature environments, such as road signs and industrial safety signs.

• Chemical and UV stability
  Polyester materials have high corrosion resistance to most chemicals and can effectively resist UV radiation, ensuring that they will not lose their reflective properties after long-term use.

• Dimensional stability
  PES has good dimensional stability, which can keep the substrate flat and accurate during the thermal transfer process, ensuring the fine transfer effect of the pattern.

• Data parameters:
  • Thickness: 200-300 microns
  • Tensile strength: 200-300 N/5cm
  • Reflective brightness: 500-700 cd/lux·m²
  • High temperature resistance: Can withstand continuous high temperatures of 150°C
  • Service life: Can last for more than 5 years outdoors

Thermoplastic polyurethane (TPU) substrate

• High elasticity and flexibility
  TPU is known for its excellent elasticity and flexibility, and is suitable for applications that require large bending and stretching, such as sportswear, automotive interiors, and certain industrial protective equipment.

• Excellent wear and tear resistance
  TPU materials can still maintain excellent wear resistance under repeated friction and mechanical impact, and are not easy to tear, so they are suitable for fields with high durability requirements.

• Light and breathable
  TPU is light and thin. While ensuring the reflective effect, it does not add extra weight or thickness. It is suitable for applications that need to fit the surface of the human body or special equipment.

• Data parameters:
  • Thickness: 100-200 microns
  • Tensile strength: 150-250 N/5cm
  • Reflective brightness: 400-600 cd/lux·m²
  • High temperature resistance: Can withstand continuous high temperatures of 120°C
  • Service life: Can be used stably for 3-5 years in outdoor environments

Comparison of PES and TPU substrates

• Durability:
  PES substrate performs better in durability, especially under conditions of high wear and tear. Although TPU also has good durability, it is slightly inferior to PES in extreme environments.

• Elasticity and softness:
  Due to its high elasticity and softness, TPU substrate is more suitable for applications that require frequent bending and stretching, such as sportswear and intimate apparel. PES substrate is more suitable for applications with high structural stability requirements.

• Breathability and comfort:
  PES substrate has a certain degree of breathability, which is suitable for making outdoor sportswear and can provide better wearing comfort. TPU substrate is more suitable for making products that require high waterproofness and weather resistance.

• Environmental protection:
  TPU substrate is highly environmentally friendly, does not contain harmful substances, and meets international environmental standards. PES substrate also meets environmental protection requirements, but is slightly inferior to TPU in environmental performance.

Process adaptability and heat transfer advantages

Compatibility of heat transfer process

• Precise transfer effect
  Both PES and TPU can quickly achieve thermal transfer effect at high temperature, ensuring fine reproduction of patterns and colors. PES can maintain dimensional stability under high temperature treatment, while TPU is suitable for transfer of curved or irregular surfaces due to its flexibility.

• Adhesion and layer combination
  Both substrates have good matching with reflective coatings and adhesives. Through reasonable process control, reflective tapes can form a uniform and firm reflective layer after transfer, ensuring long-term use effect.

Surface treatment and adhesion

• Surface modification of PES
  PES substrate can improve adhesion through special surface treatment technology (such as plasma treatment) to ensure that the reflective coating is not easy to fall off under high-intensity environment.

• Flexible adaptation of TPU
  TPU material can use its flexible characteristics to achieve perfect fit with complex curved surfaces during thermal transfer, providing customers with higher customization possibilities.

Application fields and customer needs

Safety signs and traffic facilities

• Advantages of PES in outdoor applications
  Due to its high temperature resistance, UV resistance and excellent anti-aging performance, PES-based reflective tapes are widely used in road safety, traffic signs and large outdoor advertising, ensuring that they remain highly reflective under various harsh climate conditions.

Sports and fashion fields

• Performance of TPU in flexible applications
  With its light and highly elastic characteristics, TPU substrates are very suitable for sportswear, reflective shoelaces and personalized reflective decorations, meeting consumers' needs for both fashion and functionality.

Industrial and logistics equipment

• Multifunctional safety tips
  In industrial sites and logistics warehousing, reflective tapes not only serve as warnings, but also need to be wear-resistant and tear-resistant. PES and TPU substrates can be selected and used according to different environments and mechanical stresses to achieve the best safety protection effect.

YSM reflective clothing tape factory PES and TPU substrate reflective heat transfer tapes each have their own advantages and can meet the needs of different fields and uses. PES substrate performs well in outdoor and industrial applications with its excellent durability and heat resistance. TPU substrate has an advantage in sports and high-performance clothing with its high elasticity and environmental protection performance.
