Products Description
Performance characteristics of PP diffuser plate
High transmittance and excellent shielding: PP diffusers offer both high transmittance and excellent light shielding. Their transmittance typically ranges from 50% to 90% and can be adjusted to meet specific needs. In lighting scenarios requiring high transmittance, such as indoor office flat panel lighting, high transmittance ensures sufficient light output. In applications requiring softer light and shielding from light sources, such as decorative chandeliers, PP diffusers effectively shield against direct glare, providing a comfortable lighting environment.
Excellent light diffusion: Utilizing the principle of refraction, reflection, and scattering of light between chemical particles and resin, PP diffusers effectively transform point or line sources into a soft, uniform surface light source. After light passes through the diffuser, the beam angle can be adjusted to 160-176°, resulting in more uniform light distribution.
01
Excellent Plasticity:
The PP diffuser panel has excellent plasticity, allowing for excellent forming, cutting, and processing capabilities. It can be easily cold-bent and formed into a variety of complex shapes through plastic molding processes to meet the needs of diverse lighting designs and application scenarios. It can also be easily cut, engraved, milled, and drilled, facilitating subsequent installation and assembly.
02
Texture and Wear Resistance:
The matte finish creates a smooth, silky texture and a premium aesthetic. Compared to conventional smooth surfaces, this matte finish offers improved wear and scratch resistance, greater stability, and maintains its appearance and performance over extended use, extending the product's lifespan.
03
Heat Resistance and Operating Temperature Range:
PP diffusers can be used for extended periods in ambient temperatures below 100°C, demonstrating excellent heat resistance. In applications involving high-heat-generating lighting fixtures, such as high-power LED downlights,

PHeat Resistance and Operating Temperature Range:
they can withstand certain temperatures without deformation or performance degradation, ensuring the normal operation and stability of the fixture
Applications
LED Lighting
Flat Lights: PP diffusers are widely used in flat lights, making the light they emit more uniform and softer, effectively improving lighting comfort and uniformity. They are widely used in indoor lighting venues such as offices, schools, and shopping malls.
Downlights:
When used in downlights, PP diffusers effectively diffuse light, avoiding the common spot problem of downlights and illuminating the surrounding environment more evenly. They are commonly used in indoor lighting in homes, hotels, and other areas.
Bulbs:
PP diffusers transform the point light source of bulbs into a uniform surface light source, improving the lighting effect and aesthetics of bulbs. They are often used in home lighting and some decorative lighting scenarios.
Lamps
As a lampshade material, PP diffusers not only provide excellent light transmission and diffusion, but also enhance the aesthetics of the lamp due to their frosted surface. They are widely used in lampshades of various types. Decorative Chandeliers: In decorative chandeliers
LED Ultra-Slim Light Boxes:
PP diffusers evenly distribute light within the light box, improving image quality and making advertising clearer and more appealing. They are widely used for advertising displays in public places like shopping malls and subway stations.
Indoor Furniture Lighting:
For wardrobe and cabinet lighting, PP diffusers provide soft light, making it easier to use the furniture while avoiding glare that could irritate the eyes, enhancing the user experience.
PP diffuser sheets are produced using a specialized extrusion process in a Class 10,000 cleanroom. First, polypropylene (PP) resin is uniformly mixed with specialized light diffusers and other additives in a specific ratio. These light diffusers scatter light within the resin, and their type and ratio directly impact the optical performance of the diffuser sheet.
During the extrusion process, parameters such as temperature, pressure, and extrusion speed are strictly controlled to ensure consistent sheet quality.
The mixed materials are then melt-extruded through an extruder at high temperatures.
The extruded sheet undergoes subsequent processing steps, including cooling and shaping, to produce a PP diffuser sheet with a specific thickness, width, and optical properties.
The entire production process is conducted in a Class 10,000 cleanroom to prevent dust and other impurities from entering the sheet, potentially affecting its optical properties and appearance.
Quality Control:
Multiple quality control steps are implemented throughout the production process. Starting with raw material procurement, suppliers are rigorously screened, and each batch of polypropylene resin and additives, such as light diffusers, undergoes quality testing to ensure that the raw materials meet quality standards.
Quality Control:t
During production, extruder parameters such as temperature, pressure, and extrusion speed are monitored in real time to ensure process stability. Semi-finished PP diffuser sheets are sampled and tested for physical indicators such as thickness uniformity and surface flatness. Before packaging, the finished product undergoes another comprehensive quality inspection, including testing for optical properties
Testing Standards
Optical Performance Testing: The company primarily tests transmittance and haze. Transmittance is the ratio of the luminous flux transmitted through the sample to the luminous flux incident on the sample, expressed as a percentage. Haze is the ratio of the scattered light flux that deviates from the incident light through the sample to the transmitted light flux, expressed as a percentage.
Testing Standards
Testing is performed using professional optical testing equipment in accordance with relevant standard methods to ensure that the optical properties of the PP diffuser sheets meet product specifications. For example, PP diffuser sheets used in indoor lighting generally require a transmittance between 60% and 80% and a haze between 50% and 70% to ensure good light transmission and diffusion.

Common Problem
What are the performance advantages of PP diffuser sheets compared to conventional diffuser materials?
PP diffuser sheets offer excellent optical diffusion properties, evenly dispersing light. They are also chemically resistant and highly flexible. Compared to conventional materials, they offer a longer lifespan and are less susceptible to deformation and yellowing.
What lighting equipment are PP diffuser sheets suitable for?
PP diffusers are widely used in a variety of indoor lighting equipment, including LED panel lights, ceiling lights, and downlights. They effectively soften the light source, reduce glare, and enhance lighting comfort.
How do I clean and maintain a PP diffuser sheet?
To clean, gently wipe the surface with a soft, dry cloth or microfiber cloth to remove dust. For stubborn stains, use a small amount of neutral detergent diluted in water. Avoid using strong solvents such as alcohol to prevent damage to the material.
What is the typical light transmittance of a PP diffuser sheet?
The light transmittance of a PP diffuser sheet is typically between 70% and 90%. The specific value varies depending on factors such as product thickness and the concentration of diffuser particles. You can choose a product with appropriate parameters based on your needs.
