Q1: What are the primary performance benefits of Eastar EN067 in polyester-based formulations?
A: Eastar EN067 is a non-phthalate copolyester resin designed to enhance flexibility, clarity, and low-temperature impact resistance in rigid and semi-rigid polyester systems. It also improves melt processability and reduces brittleness without compromising thermal stability or hydrolytic resistance.
Q2: Is Eastar EN067 suitable for food-contact applications?
A: Eastar EN067 is formulated to meet broad regulatory expectations for indirect food contact in packaging and processing equipment components. Final compliance depends on the complete formulation, processing conditions, and applicable regional regulations—users must conduct full regulatory validation for their specific application.
Q3: How is Eastar EN067 typically incorporated into polyester resins?
A: It is commonly added during compounding—either as a dry blend prior to extrusion or directly metered into the melt stream. Compatibility with PET, PBT, and other polyesters is generally good, though optimal dispersion may require adjustment of screw design and temperature profile.
Q4: Does Eastar EN067 affect crystallization behavior in semi-crystalline polyesters?
A: Yes—Eastar EN067 acts as a crystallization modifier, typically reducing overall crystallinity and slowing crystallization kinetics. This can improve dimensional stability and reduce warpage in injection-molded parts, especially in thicker sections.
Q5: Can Eastar EN067 be used in thermoplastic elastomer (TPE) blends?
A: While not a primary TPE base polymer, Eastar EN067 is frequently employed as a soft-segment modifier or compatibilizer in polyester-based TPE formulations to fine-tune hardness, elasticity, and low-temperature flexibility.
