Product Description Product DescriptionAttributeSpecific PerformanceImpact on SpeakersTechnical - Mechanical PropertiesTensile strength: 3 - 15 MPa (varies by formulation); Elongation at break: 100% - 800%,enabling deformation recovery without crackingEnsures structural stability under external forces (e.g., drops, pressure). High elongation prevents damage from sudden impacts, maintaining speaker integrityAcoustic Damping CoefficientDamping coefficient range: 0.2 - 0.6 (tested via dynamic mechanical analysis), effectively absorbs mechanical vibrations at 20 - 20kHz audio frequenciesMinimizes resonance in speaker enclosures. Reduces frequency - specific distortion, enhancing audio clarity across bass, mid, and treble rangesThermal Expansion Coefficient150 - 250 × 10 / °C (at 23 - 70°C), compatible with common speaker plastics (e.g., ABS: 70 - 100×10 / °C; PC: 60 - 70×10 / °C) for multi - material assembliesPrevents warping or delamination in temperature - fluctuating environments (e.g., car audio, outdoor events). Ensures long - term fit of TPE components (gaskets, seals) with speaker casingsMelt Flow Index (MFI)5 - 30 g/10min (at 190°C/2.16kg), adjustable via polymer blend ratiosControls injection molding speed and precision. Lower MFI for thick - walled parts (e.g., large speaker bases); higher MFI for intricate details (e.g., grille edges), ensuring consistent part qualityAdhesion CompatibilityForms chemical bonds with PP (peel strength: 5 - 15 N/cm), ABS (peel strength: 3 - 10 N/cm) without primers, tested per ASTM D903Enables seamless integration of TPE components (e.g., gaskets, grips) with speaker casings. Reduces assembly steps and improves structural cohesionSafety and HygieneMade of non - toxic, odorless TPE, compliant with relevant international safety standards (e.g., RoHS, REACH)Ensures no harmful substances release, providing a safe using experienceExceptional DurabilityHigh abrasion resistance and tear strength, can withstand daily wear - and - tear, accidental bumps and dropsMaintains speaker structural integrity over time, reducing repair and replacement costsEnhanced Sound QualityExcellent damping properties, effectively reduces unwanted vibrations and resonance within the speaker housingImproves sound clarity, reduces distortion, and delivers a more balanced and immersive audio experienceFlexibility and Design FreedomAvailable in a wide range of Shore hardness levels (e.g., Shore A 20 - 90), can be molded into complex shapesEnables diverse and ergonomic speaker designs, meeting different aesthetic and functional needs Company Profile
