0.8mm ESD Antistatic PET Transparent Sheet

Fearther of ESD Polyethylene terephthalate (PET) Transparent Sheet:
Polyethylene terephthalate is a crystalline polymer, is 1.30 ~ 1.38 g/cm3 density, melting point at 255 oc to 260 oc, has the most strong toughness, in thermoplastic polyethylene terephthalate ethanol in relatively wide temperature range, maintain its excellent physical and mechanical properties, the influence of the temperature of 20 oc and 80 oc is small, the permeation rate of polyethylene terephthalate as packaging materials is still belong to resistance became well.Low hygroscopicity, keep dimensional stability.

Polyterephthalic acid ethanol at a higher temperature, can also be resistant to fluorohydrogen acid, phosphoric acid, acetic acid, ethyl diacid, but hydrochloric acid, sulfuric acid, nitric acid can make it suffer different degrees of damage, such as tensile strength decline.Strong alkali, especially under high temperature, can hydrolyze its surface, among which ammonia water plays a more dramatic role.Ethyl acetate, butanone;Xylene, naphthalene, ethylene glycol methyl ester, methanol, acetic acid, etc. are not corroded at room temperature or near their boiling point, dissolved in o-chlorophenol, tetrachloroethane, cresol mixed solution or excessive nitrobenzene.

Performance of polyester sheet (PET sheet) series:

PET sheet material series (PET sheet material) includes PETG, APET, PCT and other varieties.

Polyester sheet has many advantages, such as excellent comprehensive performance, high transparency, good strength and easy post-processing.As a result of intensity is good, the product of same thickness, its protective effect is better than PVC sheet material apparently, more main is the transparent crystal of polyester sheet material increased the effect of packing, make packing went up a higher class.Again, it is non-toxic, odorless, tasteless, in line with the hygienic requirements of food packaging, there is no PVC sheet incineration when the secondary pollution of the environment.

Amorphous polyester sheet (APET sheet)

APET sheet is obtained by extruding polyester resin modified by m-phthalic acid and diethylene glycol.APET sheet has high transparency;At the same time, PET has many advantages, such as non-toxic, high gloss, good mechanical properties, barrier properties, printing properties;Easy embossing decoration;Easy metallization;You can sterilize it with r rays;Waste can be economically treated, including recycling, combustion treatment, burning only carbon dioxide and water, do not produce harmful substances.However, APET is not resistant to ultraviolet radiation, and APET has good electrical insulation performance.

APET also has many properties far more than PVC, such as good low temperature resistance, excellent friction resistance, etc., is a promising new plastic packaging materials, its application field is being further explored, expanding process.

Blister molding conditions of APET sheet (annex table 1) : molding temperature is 90℃ ~ 120℃;Mold temperature is 30℃ ~ 50℃.After the temperature reaches 120℃, APET becomes opaque, i.e., post-crystallization. For materials with a thickness of 3 ~ 4mm, post-crystallization has begun during the heating process.The exhaust channel of APET vacuum blister molding mold is 20% ~ 30% more than HIPS and PVC.APET single membrane is more difficult to heat seal than composite membrane.The thermal sealing of APET membrane to APET membrane (one-component packaging material) is realized in the temperature range of 160 ~ 240℃ and the thermal sealing time of 0.7 ~ 2.5s.

Amorphous polyester sheet material (PETG)

GPET, also known as PETG, is an amorphous PET resin modified with cyclohexanedimethanol. Its melting point is relatively low, only 180℃ ~ 200℃.PETG sheet has the characteristics of the APET sheet, its biggest characteristic is heat sealing performance is outstanding, seal fit sealing quality is reliable, easy to operate and hot compared with APET, PETG at very high molding temperature crystallization, for vacuum forming, and even able to get the clear outline of complex geometry shape but because its price is more expensive, applications.

The chemical stability of PETG is the same as that of APET.PETG or PETG/APET/PETG plastic cover can be heat sealed.Bonding is the same as APET.

Crystallization of vinegar (CPET)

CPET is a kind of PET affected by crystal nucleus, which can make the material crystallize rapidly in the process of processing.Heat resistance is a function of the crystallinity (up to 30% maximum crystallinity) that is formed during thermal molding.CPET is highly resistant to air and water vapor.Chemical stability is similar to APET and PETG.
