PMMA Diffuser Features and Technical Indicators

China Mirror Acrylic Sheet Factory will give you an introduction to the characteristics and technical specifications of the PMMA diffuser.
1. Features
High brightness: At the same penetration rate, brightness can be improved compared to conventional diffusers.
Excellent shielding effect: the light source has good diffusion and homogenization ability, and the effect of shielding the lamp is excellent.
High dimensional stability: low water absorption warpage and excellent dimensional stability.
Excellent durability: It is not easy to have yellowing in the accelerated test of ultraviolet aging.
Excellent quality assurance: All series of products have passed the UL-94 and RoHS banned poison test.

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...

What is Diffuser Plate?

Diffuser Plate/Diffusion plate  cause a great deal of interference for light, regardless of the original design of the light distribution curve. The beam angle will trun into 160 ~ 176 °as long as it goes through the diffuser plate. So it will present a hazy feeling if you see from the side. Related products:  Diamond Diffuser Plate(K12 Pattern) According to the classification of optical principle, diffusion plate is only divided into two kinds, one is to make beam angle larger while another kind maintain the original angle. According to the material classification: glass, polystyrene (PS), polycarbonate (PC), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate PET, PMMA, MMA .... etc. Translucent polymeric materials or synthetic materials can be made into diffusion materials for different applications. Any questions about  Diffuser Plate/Diffusion plate welcome to contact us.
