PET-GF Engineering Composite with a high molecular weight has a wide-ranging engineering application. As PET is reinforced with glass fiber, its mechanical, electrical, thermal and chemical properties as well as environmental, tolerance, creep, thermal expansion coefficient (like aluminum and brass) and, to a very large extent, extrusion capability improve. As the proportion of glass fiber and the production method (used in the production of extrusion parts and heat-deformable plates) vary, it has a wide range of applications. Among other things, it can be used in the production of household and automobile equipment requiring a high shock absorption structure, construction elements, case coating for such equipment as printers, copiers, cartridges, agricultural equipment including mowing machines, tractor engine cover, automotive spares, material transportation facilities such as palettes, crating, household equipment such as furniture as well as electrical and electronic equipment. Thanks to its very good dielectric properties, high thermal resistance and self-extinguishing characteristics, it is being increasing used in electrical, electronic, high temperature, spark-generation environments and direct-heat applications. Among other things, reference can be made to lamp-holders, cases and electrical sockets. Polynite is produced from polyester polymer compound combined with special-purpose glass fibers and other additives supplied in two versions: extrusion and compressive. The physical and chemical characteristics measured for the product are draw, bend, impact, pressure, MFI-IV and proportion of glass fibers.

Consistent with SNIA technology, the production process for this product starting with the mixing of monomers as feedstock input to the reactors for polymer solution in Dimethylformamide (DMF) in the Chemical Area through to fiber production, drawing, finishing and packaging is continuous and that at each stage samplings and controls are conducted and finally the product is graded and released in accordance with the test results. Bright, dull and semi-dull products are normal products but colored, super-white and antibacterial products are customized. The product is packaged in bales weighing ± kg and then put in covered polypropylene jute and rod guards. The bales measure ** mm. - tons of the product can be transported in a -foot container. 

یک خط اکستروژن ورق شامل یک اکسترودر (دو یا تک پیچ)، مجهز به تعویض صفحه نمایش به علاوه یک پمپ دنده، و به دنبال آن یک میکسر است.اتیک (گاهی اوقات یک بلوک تغذیه کواکستروژن که قبل از یک یا چند مجموعه اکسترودر اضافه شده است.، همانطور که قبلا توضیح داده شد) است.. ، تغذیه یک صفحه سطح منقضی می شود.

در حال حاضر، خط اکستروژن ورق پت تهویه‌شده بدون خشک‌کن دوقلو که توسط Suzhou Jwell راه‌اندازی شده است.، می‌تواند تکه‌هایی را با حداکثر محتوای آب اولیه ppm پردازش کند. علاوه بر این، افت ویسکوزیته در داخل . دسی لیتر بر گرم کنترل می شود.

Like other manmade fibers, polyester fibers are produced using industrial methods. Thanks to their characteristics they are good substitutes for such natural fibers as cotton. They are produced by combining dimethyl terephthalate, monoethylene glycol or terephthalic acid (substitute for the dimethyl terephthalate raw materials) in the presence of good catalysts. Titanium dioxide is used to produce a semi-dull product. Also, in the production process prior to packaging, the fibers are submerged in finish (.%). For such physical characteristics as the diameter and fineness of filaments, polyester yarn production and supply is customized. The chief application of texturized polyester yarn is filament-weft or circular yarns. The advantages of polyester yarn are:
