Vente à chaud Rouleau de feuilles d'APET Fabricant chinois

1.Polyester polyester, formerly known as polyterephthalate.Also known as titron.The abbreviation is PETP, or PET for short. It takes polyethylene terephthalate as raw material from polycondensation of dimethyl terephthalate from ethylene glycol and terephthalate.

The main advantage of thick sheet made by extrusion.

1.APET Sheet High mechanical strength.Compared with other tablets, it has a large tensile strength, equal to 5-10 times of polyethylene.In addition, it also has the advantages of stiffness and impulse resistance.

2APET Sheet .Heat and cold resistance is good, the melting point at 260℃, softening point at 230-240℃, in the case of high temperature, its shrinkage rate is still very small, has an excellent dimensional stability.Heating it for a long time at high temperature or using it at low temperature will not affect its properties.

3.APET Sheet Oil resistance, resistance to good, not easy to dissolve.It has good resistance to acid corrosion and can resist the erosion of organic solvents and oils, but it is easy to deteriorate in contact with alkali.

4.APET Sheet Water vapor, water and gas transmittance is very small, therefore, has a good moistureproof and waterproof. 

5.APET Sheet Has good air tightness, prevents the peculiar smell to pass through the property is better than other plastic sheet material.

6.APET Sheet Good transparency, transmittance in more than 90%.

7.APET Sheet Prevent poor transmission of ultraviolet rays.

8.With high electrostatic

9.Good adaptability to environmental protection, economic and convenient recycling, burning its waste, do not produce harmful substances to the environment.

(2) combustion characteristics: continue combustion after leaving the fire.When burned, it explodes into fragments and appears as a yellow flame with greenish blue edges.Polyester sheets can be easily printed on letterpress or offset.If high gloss and scratch resistance are required, the film can be printed on the surface and coated with nitrocellulose.If printed on the back, the high transparency of the sheet can enhance the gloss of the printing.But the choice of printing ink is very important, must be used when laminating adhesive has a good affinity.

(3) for blister, folding box, packaging, printing, business card printing, etc.The price is slightly higher than PVC
