Now we use the sheet of plastic is not a pure substance, the plastic board is to plastic as the main raw material, adding many of the ancillary components to the performance of stable plastic plate. Plastic plate is the main component polymer, auxiliary agent has many kinds of, filler, plasticizer, lubricants, stabilizers and coloring.
Synthetic resin is the most important component of plastic sheet, and the content of plastic sheet is 40% ~ 100%. Therefore, the properties of the synthetic resin directly determine the properties of plastic sheets. Packing also called filler, which is used to improve the strength and heat resistance properties of plastic sheet. The packing can be divided into two types of organic and inorganic filler filler, the former such as wood flour, rags and woven fabric etc., the glass fiber, silica and carbon black. Plasticizer is used to increase the plasticity and softness of plastic sheet. Plasticizer can be mixed with resin, non-toxic, no odor, light and heat stability is good, now is more common is a two formic acid esters. Stabilizer can prevent the synthesis of resin in the process of processing and use of the process of light and heat of the phenomenon of decomposition and destruction. The color of the plastic sheet is now a lot of variable, which a colorant which has great effect on, colorant so that plastic has a bright, beautiful color, common organic dyes and inorganic pigment as colouring agent. The lubricant in the plastic plate is used to prevent the use of plastic in the form of plastic, which makes the surface of the plastic plate is very beautiful and smooth.
