​NE Series  High Gas-Tightness / Heat-Resistant / Glossy Nylon   

NE series is an engineering nylon material for both injection molding and blow molding processes, which comprises PA and a clay mineral of Montmorillonite(モンモリロン石). Montmorillonite is a very soft phyllosilicate group of minerals that form when they precipitate from water solution as microscopic crystals, its particles are plate-shaped with an average diameter around 1 μm and a thickness of 9.6 nm. Hence, we also call NE series as Nano-Grade PA or Nano Nylon.

Small amount of this clay getting compounded in NE series perfoms the same tensile stress and heat deflection temperature (HDT) as PA6+20% GF, and the density also keeps the same simultaneously. Due to the property of nano-grade particle, furthermore, Montmorillonite would be easier to penetrate in between each individual nylon molecule. this the reason why products made of NE series could show excellent gas tightness and better surface property than general PA without glass fiber (GF).     



​Superiorities of NE Series 

  • Excellent mechanical performance and chemical resistance 

  • Remarkable heat durability performing deformation resistance

  • Outstanding gas tightness providing a cost-reduced alternative to substitute expensive metal

  • Higher flatness and gloss than non-GF-compounded PA

  • Nice mobility increasing process efficiency

  • Decreasing 40% moisture absorption

  • Notable dimension stability acting the best eco-friendly material choice for products necessitated being electroplated under high temperature situation

     APPLICATIONS OF NE SERIES                                                                                                             

    Since 1950, people have devoted to develope HDPE fule tanks for vehicles. Viewing material cost, processing difficulty, weight, designing flexibility etc., HDPE is far better than metal. However, the moleclular structure of HDPE is similar to petro-fuels brings about a problem of insufficient gas tightness. Gasified fuels are easier to emit out of tank walls to the air. Gradually, smart engineers had provided other ways in past few years to conquer the drawback of gas emission, such as Fluoride treatment, multi-layer extrusion integration,barrier agent mixture and increasing thickness of tank walls. There are some  disadvatages yet as below:

    In consideration of gas tightness, PA6 performs more excellent than HDPE. Nevertheless, PA6 existing in the melting condition has relatively higher melting index, this phenomenon causes PA6 an impossibility to be formed by efficient blow molding.

    Now, we launch a new type of NE-series PA, W14NE-8088I. This new PA features high gas tightness, providing auto industry the best choice of material to produce fuel tanks by blow molding. W14NE-8088I has various superiorities as below:

    1) Excellent gas tightness property, reaching 0.115 g/m²/24hrs with monolayer of W14NE-8088I.
    2) Being simple to be recycled, since monolayer composition
    3) Effortless processing procedure by general blow molding machines
    4) Remarkable heat resistance, without heat deformation even placing in engine chamber
    5) Being possible to endure a 3-m-high ball-dropping test at -20°C
    ​6) Methanol-enduring test approved

    <NOTE> According to the lastest regular in U.S., the maximum gas emission vaule is 1.5 g/m²/day

                                                                                                                                                                                        Specification (W14NE-8088I)


    Nano nylon is a high-tech composite of nano mineral and nylon, features excellent gloss and heat resistance. Both advantages make it well-known in auto-lamp industry of Taiwan with scores of f
    avorable comments. Especially the excellent gloss property with remarkable flatness is always shown on various headlamp reflectors again and again. Nano nylon performs high yield rate of 95%, and optimize the balance among shrinkage rate,melting mobility and dimension stability simultaneously. Thus, we sincerely recommand auto-lamp enterprises to select our material for prdocing the highest-quality headlamp all over the world.

    According to two differenct process of light housing, i.e. coating and non-coating primer painting before electroplating, we launch various nano nylon to match customers' demands. Of course, these nano nylon materials are also allowable to act the basic materials for other products, not only limited for light housing, such as car door handles. 

    With Primer Coating Before Electroplating

    For this case, there are two different curing processes applying onto the headlamp reflectors after formation by injection molding and before the subsequent electroplating. This curing difference involves whether the second shrinkage gets happend after the primer dries. One is cured by ultraviolet light, another is cured by the oven. Moreover, light housings might have latches/ latch holes or not in accordance with mechanical structure design. Here, we formally classify the suitable nano nylon models corresponding to above variant situations:
    1) W14NE2740-M5 is for UV curing process or structure with latches/ latch holes to enhance the elasticity of latch junctions. 
    2) W14NE2740-M6 is for oven curing process.

    Please note that if the product has pairs of hatches/ hatch holes and should be cured by an oven, we still recommand customers to select W14NE2740-M5 as the material.


    Without Primer Coating Before Electroplating**
    After long-time research and development about the double-covering technique, we also launch W14NE2640 and W14NE6640 nano nylon materials. These two models of PA materials performs high surface flatness, heat resistance and impact resistance. Furthermore, they also show a outstanding balance on customers' products among formation shrinkage, plastic mobility, dimension stability and so on. As what we could imaginne that removing the process of primer coating would decrease material cost, simplize process and provide more eco-friendly procedure (Coating sometimes is a polluting process!). By means of specific mixtures of color masterbatch or pigment powder into these nylon materials, manufacture even might withdraw the electroplating process to display highly glossy surfaces as well.
