How Does Infrared Transmission Masterbatch Work?
The unique optical behavior of IR Transmission Masterbatch comes from a combination of advanced pigments and specialized formulation design.
1. Selective Absorption of Visible Light
Pigments purposely absorb visible light (400–700 nm), giving the material a dark, opaque look that hides internal components.
2. High Transparency in the Infrared Region
In the near-infrared spectrum (780–2500 nm), these pigments allow extremely high transmission, enabling IR devices to function properly.
3. Excellent Polymer Compatibility
Through twin-screw extrusion and refined dispersion techniques, pigments integrate smoothly with the carrier resin—ensuring consistent optical performance and high production stability.

We have the capability to produce masterbatches suitable for a variety of polymers mentioned below, and many more. If you’re working with a material that isn’t listed here, please don’t hesitate to reach out to our knowledgeable technical team to explore the possibility of meeting your specific needs.
LDPE
Low Density Polyethylene – Somewhat more translucent than HDPE and considerably more pliable, primarily employed in flexible packaging, tote bags, pliable tubing, film applications, and similar uses. Like HDPE, it has limited transparency characteristics. It exhibits outstanding chemical resistance to alcohols, acids, and alkalis but has restricted resistance to hydrocarbon solvents and mineral oils. Prolonged exposure to UV radiation can initiate degradation.
HDPE
High-Density Polyethylene – Featuring a somewhat milky-white appearance, this material finds wide application in rigid bottle packaging, injection-molded caps and closures, crates, and more. Its natural opacity can limit the degree of transparency attainable. HDPE exhibits superior chemical and solvent resistance when compared to LDPE.
PPHO / PPCO
PPCO Random & PPHO – A polymer with moderate clarity, employed in the production of caps and closures. It is also utilized for crafting household items, buckets, toys, and storage containers. Polypropylene offers flexibility without significant limitations on color or special effects. Random copolymer boasts greater clarity compared to homopolymer and is better suited for creating translucent shades.
PPCO Block – Similar to PPCO but enhanced for increased impact resistance. An additive renders the polymer white, resulting in high opacity. This characteristic may limit the achievable transparency.
PET
Polyethylene Terephthalate (PET) – Polyester materials exhibit robust mechanical strength along with excellent chemical resistance and barrier properties. PET is frequently chosen for the production of carbonated beverage containers. Moreover, polyester can be spun and employed in textile manufacturing for clothing. PET is highly transparent, making it an excellent choice for translucent packaging, although a subtle hint of “yellowing” may impact extremely light tints.
PBT
Polybutylene Terephthalate – A crystalline thermoplastic engineering polymer frequently employed as an insulating material within the electronics sector. This substance belongs to the polyester category, showcasing a remarkable equilibrium of attributes and processing qualities.
GPPS
General Purpose Polystyrene – Exhibiting a glass-clear appearance but possessing minimal impact resistance, this material finds its primary application in CD cases. Its notable clarity renders it suitable for creating translucent hues, although an occasional violet tint may be discernible.
HIPS
High Impact Polystyrene – Derived from GPPS by incorporating an impact-enhancing agent to boost its resistance to impacts. This added component results in the polymer becoming white, and different formulations provide varying degrees of opacity. Typically employed in the fabrication of game pieces, toys, and similar items. Its pronounced whiteness can pose challenges when aiming for translucent coloration. Specialized alternatives like K-Resin and Styrolux are accessible in the market to attain the same level of translucency as GPPS.
ABS
Acrylonitrile Butadiene Styrene (ABS) – A more robust iteration of High Impact Polystyrene (HIPS) employed in high-value components. ABS exhibits greater durability compared to HIPS-made components, although it encounters similar challenges when attempting to achieve translucent colorations. Just like HIPS, ABS offers specialized translucent variants. Owing to its durability, ABS is commonly used in crafting casings for power tools.
PA66 / PA6
Polyamide (6, 66) – Nylon represents a versatile grade extensively employed in mechanical construction and maintenance. Its popularity stems from its excellent blend of mechanical strength, rigidity, mechanical damping characteristics, and effective electrical insulation capabilities. Consequently, nylon is a preferred material for manufacturing electrical enclosures. PA66 serves as a common alternative to metal across diverse applications, with its chemical and physical attributes closely resembling those of PA6. PA6 exhibits superior impact resistance and resistance to solvents, albeit with a heightened susceptibility to moisture absorption.
SAN
Styrene Acrylonitrile Copolymer – Possessing transparency and outstanding chemical and heat resistance, SAN also boasts good rigidity, tensile strength, and flexural strength. Thanks to its high-gloss finish, SAN is commonly chosen for cosmetic packaging purposes. However, achieving light tint colors with SAN can be challenging due to the violet dyestuffs inherent in the material, which are utilized to enhance its visual appearance during manufacturing.
PETG
Polyethylene Terephthalate Glycol – PET with the incorporation of glycol. This glycol addition enhances flow properties but diminishes strength. PETG can be extruded to create bottles and can be formed into sheets for producing ‘blister’ style packaging.
TPE / TPU
Thermoplastic Elastomer (TPE) or Thermoplastic Polyurethane (TPU) – TPU finds diverse uses in applications such as automotive instrument panels, caster wheels, power tools, medical devices, as well as various extruded film, sheet, and profile applications. TPEs are employed across a wide range of applications in industries spanning automotive, medical, construction, electrical, appliances, packaging, and industrial sectors.
