Frequently Asked Questions
PET GF30 vs PBT GF30 — which is better?
PET GF30 has higher HDT (225°C vs 205°C), better surface gloss, and slightly lower cost. PBT GF30 has faster crystallization (shorter cycle time), better impact resistance, and lower moisture sensitivity. For high-temperature electrical connectors, PET GF30 is preferred. For automotive connectors requiring impact resistance, PBT GF30 is standard.
