Factory wholesale Polyphenylene Oxide - Engineering plastics heat resistant PPA-GF, FR for breaker and bobbins – Siko Detail:

Polyphthalamide (aka. PPA, High Performance Polyamide) is a subset of thermoplastic synthetic resins in the polyamide (nylon) family defined as when 55% or more moles of the carboxylic acid portion of the repeating unit in the polymer chain is composed of a combination of terephthalic (TPA) and isophthalic (IPA) acids. The substitution of aliphatic decides by aromatic decides in the polymer backbone increases the melting point, glass transition temperature, chemical resistance and stiffness.

PPA based resins are molded into parts to replace metals in applications requiring high temperature resistance such as automotive power train components, the housing for high temperature electrical connectors and many other uses.

The glass transition temperature of PPA increases as the amount of TPA increases. If more than 55% of the acid part of a PPA is made out of IPA, then the copolymer is amorphous. The properties of semi crystalline polymers v amorphous polymers are described elsewhere in detail. Briefly, crystalline helps with chemical resistance and mechanical properties above the glass transition temperature (but below the melting point). Amorphous polymers are good in warpage and transparency.

PPA Features

PPA material has excellent combination properties, which performs well at thermal, electrical, physical and chemical properties. Especially under high temperature PPA still has high rigidity and high strength, together with excellent dimensional accuracy and stability.

PPA Main Application Field

Special using grade for Automotive water temp control assembly and thermostat body part.

Field	Application Cases
Auto Parts	Auto Water Temperature Control Assemblies, thermostat body part, structure parts, dynamic pump, clutch part, oil pump etc.
Electronic and Electrical	Connector, SMT connector, Breaker, socket, bobbins etc.
Precision industry and mechnical parts	Power steering pump parts, steam oven parts, hot water boiler connectors, water heater accessories
