Optical properties of plastic sheet

Plastic optical characteristics include two categories: one for the transfer characteristics, including light transmission, reflection, scattering and refraction; the other for light conversion features, including light absorption, thermal, photochemical, optoelectronics and light photochromic and so on.Used to characterize light transmission characteristic indicators are transmittance, haze, refractive index, birefringence and the dispersion and so on.In the indicators, the light transmittance and haze two indicators main characterize translucent of the material,the refractive index, birefringence and scattering three main indicators used to characterize the quality of translucent. A good transparent material, requiring the excellent performance and balanced.

Plastic Artist-Acrylic Processing Technology

Acrylic can be used casting, injection molding, extrusion, thermoforming, laser engraving, laser cutting and other processes. Casting molding Casting molding for forming plexiglass sheet, bar and other profiles, that is, body-bulk polymerization method of forming profiles. After casting molded products need to be post-processed, post-processing conditions are incubated at 60 ℃ 2 hours, 120 ℃ for 2 hours. Injection molding Injection molding using suspension polymerization obtained pellets, molding in the ordinary plunger or screw injection molding machine. Process parameters include screw injection molding machine, plunger injection molding machine, barrel temperature, injection molding products also need to eliminate the internal stress treatment, processing in the hot air circulation oven at 70 ~ 80 ℃, processing time as the thickness of acrylic products, the general All about 4 hours. Thermoforming Thermoforming is the process of making plexiglass sheets or she...

The Classification Of Acrylic Sheet

  Acrylic Sheet   is available in a wide variety of colors and have excellent overall properties, providing designers with a wide range of options. Acrylic sheets can be dyed and painted on the surface, screen printing or vacuum coating. In general, it is divided into the following two categories. Acrylic cast sheet: high molecular weight, excellent stiffness, strength and excellent chemical resistance. This  Diffuser Acrylic Sheet  is characterized by small batch processing, unmatched flexibility in color system and surface texture effects, and a full range of specifications for a variety of special applications. Acrylic extruded sheet: Compared to the cast sheet, the extruded sheet has a lower molecular weight and a slightly weaker mechanical properties. However, this feature facilitates bending and thermoforming processes and facilitates rapid vacuum forming when handling larger sheets. At the same time, the thickness tolerance of the  Extruded Sheet  is...

Is Acrylic Suitable for Lights?

When decorating a room, in addition to some decoration materials, you also need to install lamps and lanterns. Because lamps and lanterns are very important in people's life and can provide lighting. In the dark night, you can work and live as in the daytime. In recent years, acrylic lamps are especially popular. There are many types of acrylic lamps, and people may not know how to choose when they are choosing. In this blog post, I will give you details on how to choose acrylic lights and what to look for when installing acrylic lights .   The advantages of acrylic lights Color The color is very durable. Acrylic panels are glossy, bright and colorful, and the colors are durable for 5-8 years. In other words, it will not change or fade in 5-8 years. Transparent High light transmission. Transparent  acrylic sheets  provide over 90% light transmission. The built-in light source provides uniform and soft nighttime brightness. Compared to neon, acrylic letters as a whole are ...
