PET GF30 FAQ
Q1: What are the main differences between PET GF and PBT GF?
PET GF typically offers higher tensile strength, higher heat deflection temperature (by ~20-30°C), and better gas barrier properties than PBT GF of the same fiber content. However, PET is more sensitive to hydrolysis during processing (requires more thorough drying) and can have a narrower processing window. PBT generally offers faster cycle times and better surface finish.
Q2: Is PET GF30 suitable for under-the-hood automotive parts?
Yes, it is an excellent candidate. Its high HDT (over 220°C), good mechanical properties retention at high temperatures, and resistance to oils and coolants make it suitable for components like sensor housings, connectors, and structural brackets in the engine compartment.
Q3: What is the most critical step in processing PET GF30?
Thorough drying is absolutely critical. PET is highly susceptible to hydrolysis (molecular degradation by moisture) at melt temperatures. Material must be dried to below 0.02% moisture content, typically at 120-140°C for 4-6 hours in a dehumidifying dryer. Improper drying leads to severe loss of mechanical properties.
