1. Background: PA material, polyamide or commonly called nylon, is manufactured by Ensinger in standard stock shapes for machining in sheet, rod and tube is one of the common engineering plastics. It has 2 kinds of material, PA6 and PA66, which are the most common nylon materials. The two structures are similar and have many things in common. So what is the difference between the two? PA66 was successfully polymerized into a PA66 polymer by Wallace Hume Carothers in 1935. The process of manufacturing PA66 by melt spinning was discovered from 1936 to 1937, and was commercialized by DuPont in the United States at the end of 1939. PA6 is a PA6 polymer synthesized by German IG Schraker using a single caprolactam as raw material ε-aminocaproic acid as initiator. The test production of PA6 fiber was carried out in 1939, and commercialization was carried out by German company Faben in 1943. 2. Structure: To analyze the difference between them, we must start with their structure. As we all know, PA6 is formed by ring-opening polymerization of caprolactam, and nylon PA66 is obtained by condensation of hexamethylenediamine with adipic acid. PA6 and PA66 have the same molecular formula, but the structural formula is different, as shown in the following figure: It is precisely because of this difference that the nature of the difference, such as the intermolecular hydrogen bonding force is d

Engineering Plastic : ABS sheet and rod ABS sheet are an emerging material in the engineering plastic industry. Its full name is Acrylonitrile Butadiene Styrene sheet. It is the most widely used polymer and combines the excellent mechanical properties of toughness, hardness, and rigid phase balance. Which unifies the various performances of PS, SAN, and BS organically. Main Features: Excellent impact resistance; Good electrical insulation performance; Good heat resistance and low temperature resistance; Good chemical corrosion resistance; Electroplatable, colored spray paint, welding; Good dimensional stability. Disadvantage: Poor weather resistance, easy to produce degradation under the action of ultraviolet light; Low heat distortion temperature, flammable; Bending strength and compressive strength are poor.

Mid-Autumn Festival Holiday Notice Chinese Mid -Auturmn Festival is a one of Chinese traditional day!. In this day, every family will get together to eat the moon cake, so it is also known as "Moon Cake Day"! This holiday usually comes around September or Octorbor. It is a time to take a needed break from work; many people have a day or two off and celebrate through the weekend. Family and friends converge to give thanks and pay homage to the full moon, sometimes with poems. To celebrate it, our company will start holiday from 2018/9/22 to 2018/9/24 ! And back to work at 2018/9/25 . Please kindly note about it! Any order or shipment, please kindly be arranged before 2018/9/22. Thanks for your attention! Best wishes !

General engineering plastics: polycarbonate PC, polyoxymethylene POM, polyamide PA, thermoplastic polyester PBT/PET, modified polyphenylene ether MPPO. What is the basic physical property of each material? 1. Polyamide: (common name: nylon, PA, PA6, PA66, PA610, PA1010, etc.). PA6: Polycaprolactam. PA66: polyhexamethylenediamine adipate. Advantages: Low specific gravity (only 1/7 of metal), "soft and soft" can be processed into various products instead of metal. Heat resistance, oil, grinding, self-lubricating (low friction coefficient); High tensile strength, excellent impact toughness, electrical insulation; Gas barrier properties, better blocking oxygen. Disadvantages: The shrinkage rate is relatively large and the dimensional stability is poor. High water absorption, easy to absorb moisture, increase in size, (hydrolysis). Easy to oxidize and yellow (pyrolysis).
