Advantages of Organic Glass



Acrylic has high transparency and a transmittance of 92%, earning it the reputation of "plastic crystal". And it has excellent weather resistance, especially when used outdoors, ranking first among other plastics, and has good surface hardness and luster. It has great processing plasticity and can be made into various required shapes and products. There are various types of plates with rich colors (including semi transparent color plates), and another characteristic is that thick plates can still maintain high transparency， Glass product   .

Glass chassis

Fully transparent organic glass chassis, organic glass casting plate: high molecular weight, excellent stiffness, strength, and excellent chemical resistance. The characteristic of this type of board is small batch processing, with unparalleled flexibility in color system and surface texture effect, and complete product specifications. Players all know that acrylic boards have excellent transparency, and colorless transparent organic glass boards can achieve a transmittance of 95%. In addition, acrylic panels also have weather resistance and strong adaptability to the natural environment. Long periods of sunlight exposure, wind and rain will not change them. Good processing performance, suitable for mechanical processing. Excellent comprehensive performance, acrylic panels not only have transparent colors, but also have many rich colors. Acrylic panels can be dyed, painted, silk printed, or vacuum coated.



form

Some plastics themselves are pure resins, such as polyethylene, polystyrene, etc., known as single component plastics. Some plastics, in addition to synthetic resins, also contain other auxiliary materials such as plasticizers, stabilizers, colorants, various fillers, etc., known as multi-component plastics.



（1） Synthetic resin

Synthetic resin refers to a polymer compound synthesized by chemical, physical, and other methods, using coal, calcium carbide, petroleum, natural gas, and some agricultural and sideline products as the main raw materials to prepare low molecular compounds (monomers) with certain synthesis conditions. These compounds have properties similar to natural resins (such as rosin, amber, shellac, etc.), but their performance is superior to natural resins. For example, synthetic resin dentures.

The content of synthetic resin accounts for 40% to 100% of all components of plastic, playing a bonding role. It determines the main properties of plastic, such as mechanical strength, hardness, aging resistance, elasticity, chemical stability, photoelectric properties, etc.



（2） Plastic additives

The main purpose of adding plastic additives to plastics is to improve processing performance, improve usage efficiency, and reduce costs. The proportion of additives in plastic materials is relatively small, but it has a significant impact on the quality of plastic products. Different types of plastics require different types and amounts of additives due to different molding methods and usage conditions.



The main types of additives are as follows:



a. Plasticizer

Plasticizers can increase the softness, elongation, and plasticity of plastics, reduce the flow temperature and hardness of plastics, and are beneficial for the molding of plastic products. Commonly used include phthalates, sebacates, chlorinated paraffins, and camphor. Our most common one is camphor.



b. Flame retardant

Additives that can improve the flame resistance of plastics are called flame retardants. Most plastics containing flame retardants have self extinguishing properties or slow burning rates. Commonly used flame retardants include antimony oxide and aluminum, boron compounds, halides and phosphate esters, tetrachlorophthalic anhydride, tetrachlorophthalic anhydride, etc.



c. Antistatic agent

Antistatic agents play a role in eliminating or reducing static electricity on the surface of plastic products. Most antistatic agents are electrolytes, and their solubility with synthetic resins is limited, which can migrate to the surface of plastics to achieve moisture absorption and eliminate static electricity.



d. Stabilizer

Plastic products undergo aging phenomena such as fading, embrittlement, and cracking under the action of light, heat, and oxygen during processing, storage, and use. To delay and prevent the occurrence of aging, stabilizers must be added. Mainly used to prevent thermal aging, called heat stabilizers; Mainly used to prevent oxidative aging, called antioxidants; Mainly used to prevent light aging, they are called light stabilizers and collectively referred to as stabilizers. The most excellent plastic stabilizer today is methyltin heat stabilizer (181), which is very effective for the rolling, extrusion, injection molding, and blow molding of hard polyethylene (PVC). Due to its high safety, it is particularly used for food packaging and high-definition hard polyethylene products. At the same time, it is also widely used in plastic doors and windows, water pipes, and decorative materials to replace other highly toxic plastic heat stabilizers. It has been widely used in the United States, Europe, and Japan. 181 methyltin heat stabilizer has been widely used in China.



e. Lubricants

Lubricants are substances added to improve the demolding performance of plastic during heating and molding, and to enhance the surface finish of products. Commonly used lubricants include stearic acid and its salts, paraffin, synthetic wax, etc.



f. Foaming agent

Plastic foaming agent is a low molecular organic substance that can vaporize at a certain temperature, such as dichlorodifluoromethane; Or organic compounds that can decompose into gases when heated. These gases remain in the plastic matrix to form foamed plastics with many fine foam structures. Commonly used include azo compounds, nitroso compounds, etc.



g. Colorants

Colorants are used for coloring plastics. Mainly used for beautification and decoration. About 80% of plastic products are made into final products after coloring.



h. Reinforcement materials and fillers

In many plastics, reinforcing materials and fillers account for a considerable proportion, especially reinforced plastics and calcium plastic materials. The main purpose is to increase the strength and rigidity of plastic products by adding various fiber materials or inorganic substances. The most commonly used reinforcement materials include glass fiber, asbestos, quartz, carbon black, silicate, calcium carbonate, metal oxides, etc
