∏POM N2640E4 ▃Long term supply PPO performance 1. non crystalline material, moisture absorption is small. 2., poor liquidity, similar to the Newton fluid, viscosity is sensitive to temperature, the product thickness is generally more than 0.8 millimeters. Readily decomposed; producing corrosive gases when decomposed. The molding temperature should be strictly controlled, the mould should be heated, and the resistance of the casting system to the material flow should be small. Water 3, polyphenylene ether's low rate of about 0.06%, but the trace moisture can lead to smooth silver and other phenomena appear on the surface of the product, Zui is good for the drying process, the temperature can not be higher than 150 degrees, otherwise the color will change. 4. The molding temperature of polyphenylene oxide is 280-330 degrees, and the molding temperature of modified polyphenylene oxide is 260-285 degrees. PPE medium resistance and light resistance: PPE of acid and alkali and other basic detergent from corrosion, in force under the condition of mineral oil and ketones, solvents will cause stress cracking of you; soluble Ji such as aliphatic hydrocarbons, halogenated aliphatic hydrocarbon and aromatic hydrocarbon will make the melt up and dissolved. PPE weak point is light fastness, long time in the sun or fluorescent lamp use to produce color change, yellow color, because ultraviolet light can cause aromatic ether chain bonding caused by split. How to improve the light fastness of PPE has become a topic. LCP electronics is the main market for LCP: surface mount electronic and electrical welding dimension stability and resistance of materials have high requirements (can use to surface assembly technology in gas phase infrared welding and welding); TPEE it contains stability without color change. It is especially recommended for injection molding applications requiring high liquidity. TPEE6356:Hytrel® 6356 is of medium modulus and nominal hardness of 63D. Stable and thermoplastic as in TPEE 5556. TPEE4069:Hytrel® 4069 is a low modulus and hardness nominal grade of 40D. Stable and thermoplastic as in TPEE 5556. The new uses of SBS and the development of new brands are imminent. With the large amount of investment in capital construction and the acceleration of high-grade highway construction, SBS is an important potential market for road asphalt modification. In the implementation of the project and put into operation, the need to further intensify research efforts, strengthen relationship with manufacturers of asphalt and road construction sector cooperation as soon as possible for the development of the domestic actual SBS modified asphalt series varieties, occupied the new application field. General performance: ABS ABS for the appearance of opaque in Ivory aggregate, non-toxic, tasteless, low water absorption rate of the products can be a variety of colors, high gloss and has 90%. ABS has good compatibility with other materials, easy to surface printing, coating and coating treatment. ABS oxygen index is 18.2, is a flammable polymer, flame yellow, black smoke, burning but not dripping, and a special cinnamon. ABS is a kind of resin with excellent comprehensive properties. It has higher impact strength and surface hardness in a relatively wide temperature range. The thermal deformation temperature is higher than that of PA and PVC, and the dimensional stability is good.
