Product Detail

Product information



Modified polyp-benzoyl-p-phenylenediamine (PPA) plastic thermal deformation temperature up to 300℃ above, continuous use temperature up to 170℃, can meet your needs for short - and long-term thermal performance. It maintains its superior mechanical properties - strength, hardness, fatigue resistance and creep resistance - over a wide range of temperatures and high humidity. Toughened Lv PPA combined with superior toughness and a certain range of hardness and flexibility, in the fastener requirements for single-use rigidity, as well as repeatable use of flexure good choice. Special grade products are also available for sprayed and electroplated surfaces, fire resistance, glycol resistance and reflexive applications.







characteristic



☆PPA strength, toughness and hardness superior performance, as well as its good heat resistance, chemical resistance and cracking resistance

☆PPA can maintain strength and hardness in high temperature and high humidity environment, and can be used to replace metal in traditional nylon and polyester

☆PPA plastic also has superior surface gloss. It can be colored instead of sprayed, thus helping to reduce the appearance of scratches and scrapes on the surface.

☆PPA plastics also have good machinability and allow short injection cycle time

Compared with PA46:

√PPA has higher thermal stability than PA46.

√PPA has better CTI/ arc resistance and infrared co-current ability than PA46;

√PPA has better chemical resistance than PA46;




Application



☆ Automotive components, including fuel, transmission and engine systems, reduce weight, cost and provide long service life;

☆ Chipset and socket, cup body welding support;

☆ Chip capacitor, switch and miniature horn, high density printed circuit board connector;

☆ For wear requirements of high occasions, such as no lubrication bearing, seal, bearing isolation ring and reciprocating open compressor parts;

☆ Connectors, controllers, sensors, motors and other key electronic parts







The vast majority of PPA resins are processed by traditional injection molding.


The PPA raw materials are pre-dried to a humidity level of less than 0.1% and then packed into heat-sealed metal village bags or boxes. These containers ensure that PPA raw materials do not need to be dried before processing.


The acceptable humidity level for the process is 0.15% or lower. Wet processing resin can reduce molecular weight, resulting in the loss of mechanical properties.


Using a desiccant bucket dryer, it is easy to dry the resin to a dew point of 25°F or lower at 175°F. Drying time depends on the absorption of water, generally within the range of 4-16 hours.

 

Injection molding melting temperature in the range of 615-650°F, the material in the barrel of the stay time is not more than 10 minutes, so that the product out of the injection molding mechanical performance is the best.


A mold temperature of at least 275°F is required for complete crystallization and optimal dimensional stability.
Parts with partially thick walls can be injected at lower die temperatures due to slow cooling.


The die temperature is very important to optimize the surface sensation of finished parts.


The mold surface temperature of mineral filler grade PPA resin for vacuum gold plating metal is required to be 350°F.

What is the PPA material? PPA is polyphthalamide. PPA is a kind of thermoplastic functional nylon with both semi-crystalline structure and non-crystalline structure. It is prepared by polycondensation of phthalic acid and phthalenediamine. It has excellent thermal, electrical, physical and chemical resistance and other comprehensive properties. It still has excellent mechanical properties, including high rigidity, high strength, high dimensional accuracy, low warping and stability, fatigue resistance and creep resistance, under the harsh working environment of continuous high temperature, humidity, oil pollution and chemical corrosion at 200℃. What is the PPA-LGF? Long glass fiber reinforced composites can solve your problems when other methods of reinforced plastics do not provide the performance you need or if you want to replace metal with lower price plastic. Long glass fiber reinforced composites can cost-effectively reduce the cost of goods and effectively improve the mechanical properfies of engineering polymers, and increase the durability by forming long fibers to form a long - fiber - reinforced internal skeleton networkl. Performance is preserved in a wide range of environments. What is the difference compared with Short glass fiber compounds? What is the application of PPA-LGF? Bicycle accessories Mechanical parts Drive belt pulley For other applications filed please contact us, and we will give you technical support.
