Long term supply of the company PA9T Plastic raw materials, please call for consultation
PA9T, also known as polyamide 9T, is one of nylon plastics. PA9T is a self created polyamide engineering plastic developed by Keli Company from raw material monomer. It is a forming material with superior heat resistance, drug resistance and sliding resistance that can withstand repeated friction.
two characteristic
Its performance is superior to that of standard nylon in some major aspects. Its advantages include: providing the same strength and toughness in dry and wet conditions, and maintaining effective strength and toughness at higher temperatures compared with standard nylon. Easy to process - good fluidity, thermal stability and low mold corrosion; High performance nylon with high thermal stability and high lubricity, low water absorption (1%, other common high temperature nylon is more than 2.6%), low warpage, chemical resistance, and high dimensional stability materials, which can reach 94V-0 at a thickness of 0.75 mm. PA9T Glass The high melting temperature (125 ℃) and high crystallinity make it have good toughness under high temperature, superior to PA66 and PA46 The friction resistance and friction coefficient are much better than those of other nylon, even more than POM And LCP. Another better performance of PA9T is its resistance to chemicals and oils, alcohols, acids, calcium dichloride, hot water and other fluids, which is almost more than all PAs, only slightly worse than PPS. Its resistance to fuel is ten times that of PA6 and PA12, close to the level of ETFE (ethylene tetrachloroethylene copolymer). These advantages can make PA9T very suitable for automobile hood products. PA9T has specifications such as glass fiber free, glass fiber containing (33%, 45%, 50%) and fire prevention, which has great development potential for market applications such as automobile hoods, electrical and electronic products. three performance
1: Nylon series resins have low water absorption.
2: Dimensional stability will not cause dimensional change and mechanical strength reduction due to water absorption.
3: High heat resistance, no bubbles will be generated during the 280 pass tin test, and it is also suitable for lead-free solder with higher use temperature.
4: Good fluidity, suitable for thin meat forming.
5: Low gas, less than other nylon resins, less easy to pollute and corrode the mold, and prolong the use of the mold.
6: High crystallization speed and short cooling time.
7: In high temperature environment, mechanical strength and rigidity decrease less, bonding line strength and recovery are good.
four Injection molding process
The aluminum moisture proof bag is used as the packaging material, which can be formed immediately after opening. However, the moisture content of particles placed naturally after opening will rise due to moisture absorption, and they need to be re dried. For the condition of re drying, if a hot air dryer is used, please take 120 ℃ for about 5 hours as the reference standard. In addition, the upper limit of drying temperature is recommended to be 140 ℃, and the drying time is recommended to be within 4 hours.
Forming conditions:
Melting point: 306 ℃
Recommended barrel temperature: 310~330 ℃
Glass transition temperature: 125 ℃
Recommended mold temperature 130-150 ℃
1. Drying: 130 ℃/3-4 hours
2. Injection temperature: 290-310 ℃
3. Mold temperature: 130~150 ℃
five application
It is mainly used for various electronic products, connectors, connectors, card holders and other products! It is suitable for electronic connectors requiring SMT (especially for lead-free soldering). It is widely used in computers, digital cameras, mobile phones, etc. PA9T gives full play to its heat resistance in the field of personal computers, digital cameras, mobile phones and other electronic equipment, and is widely used in the plug (connector) for memory connection and charging. In addition, due to environmental problems in recent years, the use of lead-free "lead-free solder" without lead has been widely popularized in the welding of electronic parts, so the high heat resistance of Japanese colali GENESTAR has also been widely praised. In addition to heat resistance and sliding property, PA9T should also focus on drug resistance to promote the application of this product in a wider range of fields such as automobile parts. [1]
