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 feedback 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. 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. 

در سال محققان دریافتند البسه ی حاوی لایکرا زیست سازگار نبوده و مشکلات زیست محیطی زیادی به همراه دارند. تاثیر منفی این الیاف بیشتر از سایر الیاف مصنوعی است.. الیاف مصنوعی دیگری نظیر نایلون از منابعی مانند نفت یا ذغال سنگ تهیه میشوند اما الاستان به صورت کامل در آزمایشگاه سنتز میشود. اگر برای تولید آن از منابع تجدیدپذیر است.فاده شود، مشکلات زیست محیطی آن کمتر خواهد شد.

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 this product can be transported in a -foot container.
