zytel HTNFR52G30BL NC010 PPA DUPONT 30% glass fiber reinforced, flame retardant, lubricated 

 To introduce the latter - the semi-crystalline PPA resins, in particular, except as noted. Semi-crystalline melting point of PPAS of about 590 ° F, the supply of the form of opaque rectangular slices. 
 PPA resin than the aliphatic polyamide such as nylon 6,6 and so on more solid hard; lower sensitivity to moisture; better thermal performance; creep, fatigue and chemical resistance is also much better. For example: PPA resin with 45% short glass fiber, the tensile strength of about 276MPa, flexural modulus of more than 13786MPa, heat distortion temperature (HDT) 549 ° F Even if the class PPA of mineral fillers, the tensile strength can reach 117MPa. PPA resin ductility as nylon 6,6, however, has developed impact modified grade PPA unreinforced resin, the notched Izod impact strength up to 20 ft · lbs / inch. 
 The poly Diaminodiphenol absorb moisture, causing plasticization and dimension change. Such as nylon 6,6, 23 ° F and relative humidity of 100% absorption of 8.9% moisture, making it the glass transition temperature by 6.5 ° C down to a 20 ° C, the increase in the size 2. 3%. Under the same conditions, PPA resin can absorb about 6% of the water, but its glass transition temperature (Tg) will not fall below 40 ° C, with the size growth does not exceed 1.0%. 
 As mentioned earlier, the PPA resin with glass-reinforced high HDT value, and can withstand high temperature short-term, for example: one for the furnace or in the vapor phase and infrared counter-current unity process. PPA resin thermal oxidative stability make it resistant to the long-term high temperature, glass reinforced grade the PPA, 20000 hours of continuous use temperatures up to 330 ° F. 
 Under normal environmental conditions, PPA resin is usually demonstrated on most of the aqueous solution of aliphatic hydrocarbons, aromatic hydrocarbons, chlorinated hydrocarbons, esters, ketones, alcohols and excellent anti insoluble. Such resins can not withstand strong acids and strong oxidants. Soluble in phenol and cresol. PPA is not inherently flame-retardant according to UL94 standard, flame retardant grades of resin rated as the VO, up to 0.031 in. thickness. 
 Although the other melting process can also be used, the vast majority of PPA resin is processed using conventional injection molding method. The pre-PPA raw materials dry humidity levels to less than 0.1%, and then into the heat sealed metal in the village within the bag or box, these containers to ensure the the PPA raw material prior to processing is no longer dry. Process acceptable humidity level is 0.15% or less. Processing of wet resin enables molecular weight reduced, resulting in the loss of mechanical properties. Desiccant hopper dryer, it is easy to 175 ° F under the conditions of the resin dried to a dew point of 25 ° F or even lower. Drying time depending on the amount of water absorption, generally in the range of 4-16 hours. 
 The mechanical properties of injection molding melt temperature in the 615-650 ° F range, the residence time of material in the machine barrel is not more than 10 minutes, so that injection out of the product. Requirements of the mold temperature at least 275 ° F in order to obtain the best products of the fully crystallized and dimensional stability. Part of the thick-walled parts, due to slow cooling in the lower mold temperature, injection molding. Mold temperature is crucial for the exogenous Best of the finished surface of the parts. For vacuum metallization into the plating metal mineral fillers PPA resin mold surface temperature of 350 ° F. 
 PPA resin outstanding physical, thermal and electrical properties, especially the moderate cost, making it a broad range of applications. These properties and excellent chemical resistance, so the PPA candidate for use in the automotive industry many. Tend to better aerodynamic body design with more high-performance motor, will increase the temperature of the engine compartment, traditional thermoplastic seem endless applicable. These new requirements of the PPA to become a candidate material for the production of the following components: car headlight reflector, bearings, pulleys, the sensor housing, fuel line components and electrical components. 
 The direction of development of the electrical components miniaturization and high-temperature solidarity and unity, like infrared consolidation and vapor phase, which requires the superior performance of the PPA. Flame retardant PPA has excellent electrical properties and high HDT value, high-high-temperature flexural modulus, the growth of thin-walled parts with minimal excess material processing, so suitable for the production of switching equipment. Connect, brush holder and motor bracket. 
 Mineral filler level PPA for reflective surfaces and gold-plated case of uses, including car headlights, decorative fittings and hardware. Without the enhanced level of impact modifier PPA has excellent balanced mechanical properties, high temperature performance. Extraordinary toughness and performance by the minimal impact of humidity, its uses include oilfield parts, military supplies, sporting goods, fan impeller and gear and personal safety products.
