Plastic films are widely used in agriculture, construction, packaging, outdoor panels, roofing sheets and automotive interior materials. In many of these applications, films are exposed to strong solar radiation for long periods. The result is obvious: higher surface temperature, heat accumulation, faster material aging and reduced comfort.
For plastic film manufacturers, the challenge is not only to block light. The real technical requirement is more precise: reduce near-infrared heat ab
sorption while keeping the required visible appearance and film performance.
This is where IR-1000 infrared reflective TiO₂ becomes valuable.
IR-1000 is a functional titanium dioxide material designed to improve reflection in the near-infrared region. In plastic film systems, it can help reduce heat build-up caused by solar radiation, especially in applications where thermal insulation, infrared reflection and appearance balance are required.
Why Plastic Films Need Infrared Reflective TiO₂
Solar radiation contains ultraviolet light, visible light and near-infrared radiation. For plastic materials, each part creates different performance pressure.
UV light is mainly related to aging risk. Visible light affects color, transparency and appearance. Near-infrared radiation contributes significantly to heat accumulation.
In plastic film applications, excessive heat can cause several problems:
- Higher surface and internal temperature
- Reduced comfort in covered spaces
- Faster thermal aging of polymer materials
- Higher cooling demand in buildings or vehicles
- Poorer user experience in agricultural, roofing and automotive applications
Traditional pigmentary TiO₂ is widely used for opacity and whiteness. However, when the target is solar heat management, ordinary pigmentary TiO₂ may not provide enough near-infrared reflection efficiency.
IR-1000 is developed for this functional gap.
Typical Plastic Applications for IR-1000
IR-1000 can be used in several plastic-related applications where infrared reflection and heat insulation are important.
Typical applications include:
| Application Area | Example Use |
|---|---|
| Agricultural films | Greenhouse films, crop protection films |
| Exterior plastic panels | Outdoor colored plastic panels, ASA co-extruded panels |
| Transparent or colored roofing | Plastic roofing sheets and daylighting panels |
| Automotive interiors | Instrument panels, leather coating and interior decorative films |
These applications have one thing in common: the material is often exposed to sunlight, and temperature control becomes part of the product value.

How IR-1000 Works in Plastic Film

IR-1000 works by improving reflectance in the near-infrared region. In simple terms, it helps the film reflect more heat-related solar energy instead of absorbing it.
For plastic film producers, the practical goal is:
Keep the required visible appearance while improving infrared reflection and lowering heat build-up.
This is important because many plastic films cannot simply become highly opaque or heavily pigmented. Some applications still require specific transparency, color, light transmission or visual appearance.
Compared with conventional pigmentary TiO₂, IR-1000 provides a more targeted approach for near-infrared reflection.
Spectral Reflectance Performance of IR-1000 in Plastic Film
In plastic film testing, IR-1000 showed higher spectral reflectance in the near-infrared region compared with competing or conventional systems.
In one LDPE plastic film formulation, the data compared different TiO₂ additions:
| Sample | TiO₂ Content | Visible Light Transmittance | Infrared Transmittance by Cary 5000 UV-Vis-NIR | Infrared Transmittance by Optical Transmittance Meter |
|---|---|---|---|---|
| IR-1000 | 2.2 PHR | 76% | 70% | 21% |
| Competitor | 2.2 PHR | 76% | 70% | 21% |
| Pigmentary TiO₂ | 0.7 PHR | 52% | 77% | 49% |
| LDPE | 0 PHR | 99% | 90% | 88% |
The test shows that IR-1000 can maintain visible light transmittance while significantly reducing infrared transmittance. This is especially relevant for plastic film applications where both light appearance and heat control matter.
The optical transmittance meter result is particularly important. IR-1000 achieved 21% infrared transmittance, compared with 49% for pigmentary TiO₂ and 88% for LDPE.
That means IR-1000 can help plastic films reduce infrared heat penetration more effectively.
Application Example: IR-1000 in Thin Plastic Film
A plastic film sample test compared a thin film containing IR-1000 with a conventional pigmentary TiO₂ formulation.
| Sample | Brightness L* | TSR 300–2500 nm | NIR 780–2500 nm |
|---|---|---|---|
| Thin Film 1 with IR-1000 | 27.79 | 0.21 | 0.40 |
| Thin Film 2 with Pigmentary TiO₂ Formulation | 27.73 | 0.18 | 0.35 |
Both films had very similar brightness. However, the film containing IR-1000 achieved higher total solar reflectance and higher near-infrared reflectance.
This comparison is valuable because the brightness values are almost the same. The improvement is not simply caused by making the film visually lighter. Instead, IR-1000 improves the infrared reflection performance while maintaining a similar visible appearance.
For colored or dark plastic films, this point matters a lot. Customers often want better heat control without changing the final color too much.

Heat Insulation Temperature Difference Test
In another thin-film insulation temperature difference test, two plastic film samples were compared.
| Sample | IR-1000 Addition | Initial Temperature | Measured Temperature | Temperature Difference |
|---|---|---|---|---|
| Thin Film A | 0% | 23.2°C | 36.1°C | 12.9°C |
| Thin Film B | 3% | 23.1°C | 29.2°C | 6.1°C |
The sample without IR-1000 showed a temperature increase of 12.9°C. The sample with 3% IR-1000 showed a temperature increase of only 6.1°C.
This indicates that adding IR-1000 can reduce heat build-up in thin plastic films under the tested conditions.
For practical applications, this supports the use of IR-1000 in heat insulation plastic films, agricultural films, roofing sheets and automotive interior films.

Why IR-1000 Is Useful for Colored Plastic Film
Many heat-reflective materials perform well in white or light-colored systems. The bigger challenge is colored or darker plastic films.
Dark films absorb more visible and infrared radiation, so they often heat up faster. At the same time, customers may not want to change the color, transparency or design effect.
IR-1000 helps address this problem by focusing on near-infrared reflection.
In thin-film testing, the IR-1000 sample and the pigmentary TiO₂ formulation showed nearly the same brightness:
- IR-1000 film: L* 27.79
- Pigmentary TiO₂ film: L* 27.73
However, the IR-1000 film achieved better reflectance:
- TSR increased from 0.18 to 0.21
- NIR increased from 0.35 to 0.40
This makes IR-1000 suitable for plastic film applications where the manufacturer wants to improve thermal performance without making the film look significantly different.
IR-1000 vs Pigmentary TiO₂ in Plastic Film
Pigmentary TiO₂ is mainly selected for whiteness, opacity, hiding power and color adjustment. IR-1000 is different. It is selected for infrared reflection and solar heat management.
| Item | IR-1000 | Pigmentary TiO₂ |
|---|---|---|
| Main function | Near-infrared reflection and heat reduction | Whiteness, opacity and hiding power |
| Suitable use | Heat insulation plastic film, colored film, roofing film | General pigmentation and opacity |
| Performance focus | NIR reflectance, TSR, reduced heat build-up | L*, opacity, visible appearance |
| Best-fit applications | Functional plastic films exposed to sunlight | Standard plastic coloration systems |
This does not mean pigmentary TiO₂ should be replaced in every formulation. The more practical approach is to choose the material based on the application target.
For normal opacity or whiteness, pigmentary TiO₂ remains relevant. For heat insulation and near-infrared reflection, IR-1000 offers a more targeted solution.
Key Benefits of IR-1000 in Plastic Film Applications
IR-1000 can bring several practical benefits to plastic film producers:
| Benefit | Practical Meaning |
|---|---|
| Improved NIR reflection | Less infrared heat absorption |
| Lower heat build-up | Better thermal comfort and insulation performance |
| Similar visible appearance | Useful for colored or designed films |
| Applicable in thin films | Suitable for plastic film and flexible plastic structures |
| Functional TiO₂ solution | Goes beyond conventional pigmentation |
For manufacturers, this means IR-1000 can help turn plastic film from a basic material into a functional heat-management material.

Recommended Testing Method for Plastic Film Manufacturers
Before commercial use, IR-1000 should be tested in the actual resin system and film structure. Plastic film performance can be affected by polymer type, film thickness, pigment loading, dispersion quality and processing conditions.
Recommended evaluation items include:
| Test Item | Purpose |
|---|---|
| Spectral reflectance curve | Evaluate reflectance from UV to NIR |
| TSR 300–2500 nm | Measure total solar reflectance |
| NIR 780–2500 nm | Measure near-infrared reflectance |
| Visible light transmittance | Check transparency or appearance impact |
| L* brightness | Compare color/lightness consistency |
| Temperature difference test | Verify heat insulation effect |
| Film mechanical properties | Confirm processing and end-use performance |
The most important point is not to evaluate IR-1000 only by appearance. Its value should be judged by NIR reflectance, TSR and temperature reduction performance.
Where IR-1000 Can Create Commercial Value
IR-1000 is suitable for plastic film applications where heat control creates clear customer value.
Potential commercial scenarios include:
| Market | Value of IR-1000 |
|---|---|
| Agricultural film | Reduce excessive heat accumulation under sunlight |
| Plastic roofing film | Improve thermal comfort under transparent or colored roofing |
| Exterior plastic panels | Reduce surface temperature and heat aging risk |
| Automotive interior films | Lower heat build-up in sun-exposed interior parts |
| Functional packaging film | Add solar heat management performance where needed |
In these markets, IR-1000 can help manufacturers differentiate products by performance rather than competing only on price.
This is a practical product-positioning advantage. Instead of selling “another plastic film,” producers can sell a film with measurable infrared reflection and heat insulation performance.
