PCTA,美國伊士曼,14471-詳細(xì)說明:
本公司 可以免費(fèi)提供各種材料物性及各種材質(zhì)認(rèn)證 如:SGS UL MSDS ROHS MDS 等證明 : 通過這些鏈接您能夠訪問供應(yīng)商資料。我們盡量保證 準(zhǔn)確數(shù)據(jù)資料; UL 黃卡含有 UL 驗(yàn)證的易燃性和電氣特性物性說明
CTA介紹:PCTA是一種共聚聚酯塑料原料。具有高透明度,良好的韌性和沖擊強(qiáng)度,優(yōu)異的低溫韌性,高抗撕性及良好的加工性能,優(yōu)異的耐化學(xué)性能,可電鍍,噴油,抗刮花,密度比PC低16%,加工成本比PC低40%,印刷、著色、電鍍性能佳,韌性比透明ABS高3倍,符合歐洲RoHS環(huán)保指令),適用于高檔次的化妝品,電子電氣內(nèi)材.玩具,高檔筆,并可取代PC在各種領(lǐng)域內(nèi)的運(yùn)用。可采取傳統(tǒng)的擠出、注塑、吹塑及吸塑等成型方法進(jìn)行加工。廣泛應(yīng)用于板片材、高性能收縮膜、瓶用及異型材市場;可以用來生產(chǎn)玩具、家用器皿及醫(yī)療用品等。
PCTA共聚物是環(huán)己烷二甲醇和對苯二酸,以及根據(jù)需要用別的酸部分取代對苯一酸所形成的聚合物。與PET相比具有較低的可萃取性,更好的耐熱性,低溫抗沖擊性和水解穩(wěn)定性。可應(yīng)用于取向和流延薄膜、熱成型盤子和單絲等領(lǐng)域。正常的PCTA共聚酯擠塑薄膜特性有:極亮的透明度、好的低溫韌性、高抗撕性和耐化學(xué)性。在合成PCTA共聚酯時(shí)改變酸的比例可使聚合物具有不同的*性質(zhì)。例如可具有高結(jié)晶熔融溫度(545F),用于制作可烘烤盤子。PCTA還可以與其它聚酯共混或填充玻纖、云母,以滿足各種性能要求。PCTA共聚酯制品可用于與食品接觸的各種用途,這在FDA規(guī)范21CFR—177—12401中已有規(guī)定,并也得到USDA許可用作肉禽類包裝材料。原料供應(yīng)商以美國伊士曼為主。

物性說明
產(chǎn)品說明 | ||||
Eastman Spectar™ copolyester (PETG) extrudes into plastic sheet that is sparkling clear, tough, chemically resistant, odor-free, versatile, easy to work with and affordable. Its toughness allows fabricators to use thinner-gauge sheet than with other common materials, resulting in lower material costs. Yet it can be extruded into sheets as thick as 12 mm (1/2 in.). It extrudes at a low temperature and will not crystallize or develop a crystalline haze. Cleaning solutions will not turn Eastman Spectar™ copolyester white. It is easy to fabricate, allowing greater design freedom. It can be laser cut, routed, welded, drilled, die-punched, bent hot or cold, or joined by screws, rivets, or bolts. It can also be cut on conventional table, band, or radial-arm saws with blades commonly used for plastic. Spectar™ copolyester can be vacuum-formed at lower temperatures than other plastics without predrying the sheet. Eastman Spectar™ copolyester can be finished easily. Its edges can be polished by using commercial edge-finishing equipment, sanding, solvents, flame-polishing or buffing. It forms clear, strong bonds with commercially available cements and solvents. It accepts screen-printing, painting, and hot-stamping easily. Surface scratches or scuff marks can be removed using a common heat gun. Sheet made from Eastman Spectar™ copolyester (PETG) is available from plastic sheet distributors throughout North America, Canada, Europe, Asia, and Latin America. This product has been GREENGUARD INDOOR AIR QUALITY CERTIFIED®. GREENGUARD Certification recognizes Eastman for manufacturing products with low chemical and particle emissions for better indoor environments.

This product has been CRADLE TO CRADLE CERTIFIED Silver. The CRADLE TO CRADLE CERTIFIED Mark is a registered certification mark used under license through McDonough Braungart Design Chemistry (MBDC). MBDC is a global sustainability consulting and product certification firm. The CRADLE TO CRADLE® framework moves beyond the traditional goal of reducing the negative impacts of commerce ('eco-efficiency'), to a new paradigm of increasing its positive impacts ('eco-effectiveness'). At its core, Cradle to Cradle design perceives the safe and productive processes of nature's 'biological metabolism' as a model for developing a 'technical metabolism' flow of industrial materials. Product components can be designed for continuous recovery and reutilization as biological and technical nutrients within these metabolisms.
