EVA is made by copolymerization of LLDPE (linear low density polyethylene) and acetic acid (VA). EVA's polymerization methods: 1, high pressure bulk polymerization (plastic products) 2. Solution polymerization (PVC processing auxiliaries) 3. Emulsion polymerization (adhesive products) 4, suspension polymerization The content of ethylene acetate (VA) is higher than 30% by emulsion polymerization. High pressure bulk polymerization is used for the low content of ethylene acetate (VA). The main factors that affect the performance of EVA are: 1, Melt Index melting index (MI, soluble finger for short) Content of 2 and VA% acetic acid The melting index (MI), the higher the content of vinyl acetate (VA), the higher the elasticity, softness, solubility and transparency. When the content of VA decreases, its performance is close to that of polyethylene (PE), and its rigidity is increased, its wear resistance and electrical insulation are improved. The content of VA will increase with increasing the number of MI, softening point, machinability and surface gloss, but the strength will decrease. Otherwise, with the decrease of MI, the molecular weight will increase, and the impact resistance and the environmental stress cracking performance will be improved. EVA is characterized by its good softness, rubber like elasticity, good flexibility, transparency and surface gloss at -50 C, good chemical stability, anti-aging and ozone resistance, and no toxicity. The mixing, coloring and processing property of the filler are good. The polarity of the acetic acid increases the elasticity and viscosity, decreases the crystalline and electrical properties, and dissolves in hydrocarbons and oils.

In easy to process design, Stanyl has the same performance as high temperature resin, such as LCP, PPS and PEEK. The advantages of the die makers and the end users include: PA46 of Stanyl - heat resistance, can be used for a long time under the hood, lead-free welding processing. Excellent chemical resistance, which can prolong the service life of the components. Because of its low creep, excellent fatigue resistance and low wear resistance, the service life can be extended, and the performance is more reliable. Excellent mechanical properties, reducing wall thickness, thereby reducing weight and component prices. The production efficiency of the molding equipment 30% can be improved by only a short period of time (because the high mobility can increase the production efficiency by increasing the number of die cavities). It provides greater design freedom because of its excellent mechanical properties and good mode flow behavior. It can easily fill the thin wall thickness of the product, so that the most advanced products can be easily injected. The regrinding rate can reach 25-50%, and the performance is not significantly reduced (while economic benefits are obtained, and the performance of the product is maintained). 80 degree C (175 F) water heat injection mold can be used for economic, safe and convenient processing. There is no flfei phenomenon, so no post processing is needed. If high temperature applications require materials with higher heat resistance, it is possible to use the same mold as PA6, PA66 or polyester without replacement. The performance of DSM material in the cluster group, announced the Stanyl PA46 DSM engineering plastics F9 high mobility launched. Stanyl PA46 F8 has high fluidity similar to liquid crystal polymer (LCP), plus the high flow characteristics and heat and warpage of thin wall or highly detailed components, which significantly reduces the cost of engineering material mass production. Equipment and technology PA6 Injection molding process conditions: Drying: if the material is sealed before processing, it is not necessary to dry. However, if the storage container is opened, it is recommended to dry in the hot air at 85 degrees centigrade. If the humidity is greater than 0.2%, it is also necessary to do a 105 - and 12 - hour vacuum drying. Melting temperature: 260~290 C. The product of glass additive is 275~280 C. The melting temperature should be avoided above 300 degrees C. Mold temperature: recommended 80 degrees C. The mold temperature will affect the crystallinity, and the crystallinity will affect the physical properties of the product. For thin walled plastic parts, if the mold temperature below 40 degrees is used, the crystallinity of the plastic will change with time. In order to maintain the geometrical stability of the plastic part, annealing treatment is needed. Injection pressure: usually in 750~1250bar, depending on the material and product design. Injection speed: high speed (for reinforced material should be slightly lower). Runner and gate: Because the solidification time of PA66 is very short, the location of the gate is very important. Gate aperture should not be less than 0.5*t (here t is the thickness of the plastic part). If the hot runner is used, the gate size should be smaller than the conventional channel, because the hot runner helps prevent the premature solidification of the material. If the subsurface gate is used, the minimum diameter of the gate should be 0.75mm.
