Solution polymeization (PVC pocessing auxiliaies)3. Emulsion polymeization (adhesive poducts)4, suspension polymeizationThe content of ethylene acetate (VA) is highe than 30% by emulsion polymeization.High pessue bulk polymeization is used fo the low content of ethylene acetate (VA).The main factos that affect the pefomance of EVA ae:1, Melt Index melting index (MI, soluble finge fo shot)Content of 2 and VA% acetic acidThe melting index (MI), the highe the content of vinyl acetate (VA), the highe the elasticity, softness, solubility and tanspaency. When the content of VA deceases, its pefomance is close to that of polyethylene (PE), and its igidity is inceased, its wea esistance and electical insulation ae impoved.The content of VA will incease with inceasing the numbe of MI, softening point, machinability and suface gloss, but the stength will decease. Othewise, with the decease of MI, the molecula weight will incease, and the impact esistance and the envionmental stess cacking pefomance will be impoved.EVA is chaacteized by its good softness, ubbe like elasticity, good flexibility, tanspaency and suface gloss at -50 C, good chemical stability, anti-aging and ozone esistance, and no toxicity. The mixing, coloing and pocessing popety of the fille ae good.The polaity of the acetic acid inceases the elasticity and viscosity, deceases the cystalline and electical popeties, and dissolves in hydocabons and oils.Pefomance chaacteisticsAntioxidationGood flexibilityGood toughnessCompliance of food contactInstitutional atingEuopean food contact, non atingPocessing methodRotational Moldinginjection moldingTest method of physical pefomance ating unit systemDensity (23 C) 0.937 g/cm3 ISO 1183Melt flow ate (190 C/2.16 kg) 10 g/10 min ISO 1133 application aeaLCP A B C EiThe ea 250-290 250-290 280-340 300-360Middle 270-290 270-290 300-340 310-350The font pat 290-310 290-310 320-340 330-350Nozzles 290-310 290-310 320-340 330-350Resin tempeatue 290-320 290-320 320-350 340-360Main usesStanyl chaacteisticsThe excellent chaacteistics of Stanyl have impotant advantages in educing cost, polonging sevice life and eliability. In easy to pocess design, Stanyl has the same pefomance as high tempeatue esin, such as LCP, PPS and PEEK.The advantages of the die makes and the end uses include:PA46 of Stanyl- heat esistance, can be used fo a long time unde the hood, lead-fee welding pocessing.Excellent chemical esistance, which can polong the sevice life of the components.Because of its low ceep, excellent fatigue esistance and low wea esistance, the sevice life can be extended, and the pefomance is moe eliable.Excellent mechanical popeties, educing wall thickness, theeby educing weight and component pices.The poduction efficiency of the molding equipment 30% can be impoved by only a shot peiod of time (because the high mobility can incease the poduction efficiency by inceasing the numbe of die cavities).It povides geate design feedom because of its excellent mechanical popeties and good mode flow behavio.It can easily fill the thin wall thickness of the poduct, so that the most advanced poducts can be easily injected.The eginding ate can each 25-50%, and the pefomance is not significantly educed (while economic benefits ae obtained, and the pefomance of the poduct is maintained).80 degee C (175 F) wate heat injection mold can be used fo economic, safe and convenient pocessing.Thee is no flfei phenomenon, so no post pocessing is needed.If high tempeatue applications equie mateials with highe heat esistance, it is possible to use the same mold as PA6, PA66 o polyeste without eplacement.The pefomance of DSM mateial in the cluste goup, announced the Stanyl PA46 DSM engineeing plastics F9 high mobility launched. Stanyl PA46 F8 has high fluidity simila to liquid cystal polyme (LCP), plus the high flow chaacteistics and heat and wapage of thin wall o highly detailed components, which significantly educes the cost of engineeing mateial mass poduction. Equipment and technologyPA6 Injection molding pocess conditions:Dying: if the mateial is sealed befoe pocessing, it is not necessay to dy. Howeve, if the stoage containe is opened, it is ecommended to dy in the hot ai at 85 degees centigade. If the humidity is geate than 0.2%, it is also necessay to do a 105 - and 12 - hou vacuum dying. Melting tempeatue: 260~290 C. The poduct of glass additive is 275~280 C. The melting tempeatue should be avoided above 300 degees C.Mold tempeatue: ecommended 80 degees C. The mold tempeatue will affect the cystallinity, and the cystallinity will affect the physical popeties of the poduct. Fo thin walled plastic pats, if the mold tempeatue below 40 degees is used, the cystallinity of the plastic will change with time. In ode to maintain the geometical stability of the plastic pat, annealing teatment is needed.Injection pessue: usually in 750~1250ba, depending on the mateial and poduct design. Injection speed: high speed (fo einfoced mateial should be slightly lowe). Runne and gate:Because the solidification time of PA66 is vey shot, the location of the gate is vey impotant. Gate apetue should not be less than 0.5*t(hee t is the thickness of the plastic pat). If the hot unne is used, the gate size should be smalle than the conventional channel, because the hot unne helps pevent the pematue solidification of the mateial. If the subsuface gate is used, the minimum diamete of the gate should be 0.75mm.PA6 poduct pefomance melting point: 210-220 degees centigadeDecomposition tempeatue: >300 CFlash point: >400 CSpontaneous combustion tempeatue: >450 CState: solid paticlesOdou: noToxicity: noRecycling: canFinal teatment: soil (hamless industial waste)Fie extinguishing agent: all kinds of fie extinguishing agents (wate, foam, powde, CO2, sand)Tanspotation: non dangeous goods and vaious means of tanspotationEC standad: non dangeous goodsPA6 Japanese MITSUBISHI: 33% glass fibe einfoced flame etadant gade 1016G-33;
