TPE Blow Molding Material
Product Description
A thermoplastic elastomer optimized for blow molding processes, featuring suitable melt strength and uniform extensibility for producing hollow, soft elastic products.
Key Characteristics
1. Suitable Melt Strength: Ensures parison stability, preventing sagging or tearing.
2. Uniform Extensibility & Resilience: Even wall thickness during blowing, resulting in soft and elastic products.
3. Good Thermal Stability: Adapts to temperature and time requirements of blow molding.
4. Smooth Surface: Good product appearance.Main Applications
Hollow soft balls, buoyancy products, squeezable bottles/containers, toys, air bladders, some medical supplies (e.g., irrigation bottles).
Processing Methods
Extrusion Blow Molding (Primary), Injection Blow Molding.
Environmental Certifications
Basic certifications like ROHS, REACH. Special certified grades (e.g., FDA) available upon request.
Color
Transparent, translucent, and various colors available.
Storage Conditions
Store sealed in a cool, dry place.
