PET的性能
(1)一般性能 PET樹脂為乳白色半透明或無色透明體,相對(duì)密度1.38,透光率為90%。PET屬于中等阻隔性材料,對(duì)O2的透過系數(shù)為50~90cm3·mm/(m2·d·MPa),對(duì)CO2的透過系數(shù)為180cm3·mm/(m2·d·MPa)。PET的吸水率為0.6%,吸水性較大。
(2)力學(xué)性能 PET膜的拉伸強(qiáng)度很高,可與鋁箔媲美,是HDPE膜的9倍,是PC和PA膜的3倍。增強(qiáng)PET的蠕變性小、耐疲勞極好(好于增強(qiáng)PC和PA)、耐磨性和耐摩擦性良好。PET的力學(xué)性能受溫度影響較小。
(3)熱學(xué)性能 純PET塑料的耐熱性能不高,但增強(qiáng)處理后大幅度提高,在180℃時(shí)的機(jī)械性能比PF層壓板好,是增強(qiáng)的熱塑性工程塑料中耐熱較好的品種。PET的耐熱老化性好,脆化溫度為-70℃,在-30℃時(shí)仍具有一定韌性。PET不易燃燒,火焰呈黃色,有滴落。
(4)電學(xué)性能 PET雖為極性聚合物,但電絕緣性優(yōu)良,在高頻下仍能很好保持。PET的耐電暈性較差,不能用于高壓絕緣;電絕緣性受溫度和濕度影響,并以濕度的影響較大。
(5)環(huán)境性能 PET含有酯鍵,在高溫和水蒸氣的條件下不耐水、酸、及堿的作用。PET對(duì)有機(jī)溶劑如丙酮、苯、甲苯、三氯乙烷、四氯化碳和油類穩(wěn)定,對(duì)一些氧化劑如過氧化氫、次氯酸鈉及重鉻酸鉀等也有較高的抵抗性。PET耐候性優(yōu)良,可長(zhǎng)期用于戶外。
Polyethylene terephthalate (or poly(ethylene terephthalate), PET, PETE, or the obsolete PETP or PET-P), is the most common thermoplastic polymer resin of the polyester family and is used in fibres for clothing, containers for liquids and foods, and thermoforming for manufacturing, and in combination with glass fibre for engineering resins.
In 2016, annual production of PET was 56 million tons.The biggest application is in fibres (in excess of 60%), with bottle production accounting for about 30% of global demand. In the context of textile applications, PET is referred to by its common name, polyester, whereas the acronym PET is generally used in relation to packaging.[citation needed] Polyester makes up about 18% of world polymer production and is the fourth-most-produced polymer after polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC).[citation needed]
PET consists of polymerized units of the monomer ethylene terephthalate, with repeating (C10H8O4) units. PET is commonly recycled, and has the digit 1 (?) as its resin identification code (RIC). The National Association for PET Container Resources (NAPCOR) defines PET as: "Polyethylene terephthalate items referenced are derived from terephthalic acid (or dimethyl terephthalate) and mono ethylene glycol, wherein the sum of terephthalic acid (or dimethyl terephthalate) and mono ethylene glycol reacted constitutes at least 90 percent of the mass of monomer reacted to form the polymer, and must exhibit a melting peak temperature between 225°C and 255°C, as identified during the second thermal scan in procedure 10.1 in ASTM D3418, when heating the sample at a rate of 10°C/minute."
Depending on its processing and thermal history, polyethylene terephthalate may exist both as an amorphous (transparent) and as a semi-crystalline polymer. The semicrystalline material might appear transparent (particle size less than 500 nm) or opaque and white (particle size up to a few micrometers) depending on its crystal structure and particle size.
The monomer bis(2-hydroxyethyl) terephthalate can be synthesized by the esterification reaction between terephthalic acid and ethylene glycol with water as a byproduct (this is also known as a condensation reaction), or by transesterification reaction between ethylene glycol and dimethyl terephthalate (DMT) with methanol as a byproduct. Polymerization is through a polycondensation reaction of the monomers (done immediately after esterification/transesterification) with water as the byproduct

Textiles
Polyester fibres are widely used in the textile industry. The invention of the polyester fibre is attributed to J. R. Whinfield. It was first commercialized in the 1940s by ICI, under the brand 'Terylene'. Subsequently E. I. DuPont launched the brand 'Dacron'. As of 2022, there are many brands around the world, mostly Asian.
Polyester fibres are used in fashion apparel often blended with cotton, as heat insulation layers in thermal wear, sportswear and workwear and automotive upholstery.
Rigid Packaging
PET bottles absorb Plastic bottles made from PET are widely used for soft drinks, both still and sparkling. For beverages that are degraded by oxygen, such as beer, a multilayer structure is used. PET sandwiches an additional polyvinyl alcohol (PVOH) or polyamide (PA) layer to further reduce its oxygen permeability.
Non-oriented PET sheet can be thermoformed to make packaging trays and blister packs. Crystallizable PET withstands freezing and oven baking temperatures.: 1378 Both amorphous PET and BoPET are transparent to the naked eye. Color-conferring dyes can easily be formulated into PET sheet.
PET is permeable to oxygen and carbon dioxide and this imposes shelf life limitations of contents packaged in PET.: 104
Flexible Packaging
Biaxially oriented PET (BOPET) film (often known by one of its trade names, "Mylar") can be aluminized by evaporating a thin film of metal onto it to reduce its permeability, and to make it reflective and opaque (MPET). These properties are useful in many applications, including flexible food packaging and thermal insulation (such as space blankets).
Photovoltaic Modules
BOPET is used in the backsheet of photovoltaic modules. Most backsheets consist of a layer of BOPET laminated to a fluoropolymer or a layer of UV stabilized BOPET.
PET is also used as a substrate in thin film solar cells.
Thermoplastic resins
PET can be compounded with glass fibre and crystallization accelerators, to make thermoplastic resins. These can be injection moulded into parts such as housings, covers, electrical appliance components and elements of the ignition system.
Other Applications
A waterproofing barrier in undersea cables.
As a fibre, spliced into bell rope tops to help prevent wear on the ropes as they pass through the ceiling.
Since late 2014 as liner material in type IV composite high pressure gas cylinders. PET works as a much better barrier to oxygen than earlier used (LD)PE.
As a 3D printing filament, as well as in the 3D printing plastic PETG.
Film for tape applications, such as the carrier for magnetic tape or backing for pressure-sensitive adhesive tapes. Digitalization has caused the virtual disappeance of the magnetic audio and videotape application.
Water-resistant paper.
