How to toughen PPa's primary crushing material before it is put on the machine
PPa (High Performance Polyamide)
High-performance polyamide plastics have a heat deflection temperature of 280 ° C and a continuous use temperature of 170 ° C to meet your short-term and long-term thermal performance. It maintains its superior mechanical properties - strength, hardness, fatigue resistance and creep resistance - over a wide temperature range and in high humidity environments. This wide range of high temperature nylon products depends on the grade you choose. It gives you the same strength as aluminum, the same hardness as steel, and the impact resistance and ductility of hard rubber. The structural grade provides improved weld line strength for larger, thicker parts. The toughened grade combines superior toughness with a range of hardness and flexibility, requiring a one-time rigidity in the fastener and a good choice for flexibility in repetitive use. At the same time, special grade products are available for sprayable and galvanizable surfaces, fire retardant, glycol resistant and reflective applications.
main feature:
Provides the same strength and toughness in both dry and humid environments.
Maintains effective strength and toughness at higher temperatures compared to standard nylon.
Easy to process: good fluidity, thermal stability, soft and low mold corrosion.
Application range:
Electronic components, electrical appliances, connectors.
Automotive applications: electrical, electronic components, transmission systems, chassis parts.
Nanjing Ligong: Polyphthalamide polyphthalamide (PPa) resin is a semi-aromatic polyamide based on terephthalic acid or phthalic acid. PPA is only one kind of Pa. It can be used in Malay. The anhydride is grafted with POE to toughen.
It can react with the groups in PPa to achieve the purpose of compatibility and toughening.
