Kraton G1701 SEBS Elastomer – Frequently Asked Questions (FAQ)

Q1: What are the key processing advantages of Kraton G1701 compared to other thermoplastic elastomers?

A: Kraton G1701 offers excellent melt processability via extrusion, injection molding, and blow molding due to its balanced molecular structure and low melt viscosity. It exhibits good thermal stability during processing and minimal plate-out or die buildup, supporting high-line-speed production in compound and finished goods manufacturing.

Q2: How does Kraton G1701 perform in soft-touch overmolding applications?

A: Kraton G1701 provides strong adhesion to many rigid substrates—including polypropylene, ABS, and polycarbonate—without requiring primers or surface treatments. Its low modulus and high elasticity deliver a premium tactile feel and consistent surface appearance, making it well-suited for consumer electronics housings, medical device grips, and automotive interior components.

Q3: Is Kraton G1701 suitable for medical or food-contact applications?

A: Kraton G1701 is manufactured under controlled conditions and is commonly used in non-implantable medical devices and food-contact-adjacent applications where regulatory compliance is required. Final suitability depends on full formulation validation, including extractables/leachables testing and compatibility with intended sterilization methods. Users should consult Kraton’s regulatory support documentation and conduct application-specific qualification.

Q4: Can Kraton G1701 be blended with other polymers, and what considerations apply?

A: Yes—Kraton G1701 is frequently compounded with polypropylene, polyethylene, and various fillers or plasticizers to tailor hardness, flexibility, and flow behavior. Compatibility is generally good with non-polar resins; however, polarity mismatches (e.g., with nylon or PET) may require compatibilizers. Thorough rheological and morphological evaluation is recommended for each blend system.
