High-Performance PPS/PPE and PPA/PPE blends

Outstanding electrical properties and excellent dimensional stability under high humidity and high temperature

High-Performance PPS/PPE and PPA/PPE blends Outstanding electrical properties and excellent dimensional stability under high humidity and high temperature

When it comes to developing a demanding application part, the challenge is to find a material with the right combination of technical properties. The PPS/PPE* and PPA/PPE blends* bring together the best of diverse high-performance engineering materials to create a compound with unique characteristics:

*PPA: Polyphthalamide | PPE: Polyphenylene Ether | PPS: Polyphenylene Sulfide

Low Specific Gravity Low Dielectric Constant Low Dissipation Factor Great Plating Ability High Dimensional Stability Low Water Absorption High Heat Resistance Moldability (No Flash)

Application areas

Where you can use the PPE blends?

5G Devices Automotive Electrical & Electronics Aerospace Industrial Energy

PPS/PPE blends

Improved CLTE and dimensional stability, less warpage and easy processing.

PPS/PPE blends’ CLTE change is linear due to the temperature change. There is no inflection point. PPS/PPE blends have small CLTE anisotropy.

CLTE: Coefficient of Liner Thermal Expansion

PPA/PPE blends

Excellent mechanical performance under high humidity and high temperature.

Great flexural modulus and low water absorption rate, no dimensional change.

Advantages brought by alloying with PPE PPE blends have stable CLTE under wide temperature ranges because the dimensional change at Tg levels is reduced by alloying PPE. PPE blends allow weight reduction and potential cost down, as PPE has the lowest specific gravity among engineering plastics.

Outstanding electrical properties

Low dissipation factor and low dielectric constant
