To meet the long-term skin contact requirements of smartwatches and fitness bands, we offer custom rubber compounds, featuring specialty fluoroelastomers. Hardness range: 50~90 Shore A – soft and conforms to the wrist. Tensile strength ≥12 MPa, resistant to repeated flexing without cracking. Passes skin irritation testing, free of allergens, and resistant to sweat, sunscreen, and other daily-contact substances. Available in a rich range of colors – any Pantone shade can be matched.
We supply specialty rubber compounds to automotive manufacturers worldwide. Core materials include FKM, HNBR, and EPDM. For new energy vehicle battery pack sealing, EPDM or FKM are the preferred choices: EPDM has low polarity and exhibits minimal swelling in alcohol/ether-based electrolytes, while FKM offers high temperature and strong corrosion resistance. Typical application achievements include passing IP67/IP68 waterproof and dustproof tests and -30°C to +85°C thermal shock cycles, with electrolyte-induced volume change of battery pack sealing rings below 8%.
We supply specialty rubber compounds to automotive manufacturers worldwide. Core materials include FKM, HNBR, and EPDM. For rotary shaft oil seals in engines, transmissions, and electric motors, HNBR or FKM are the preferred choices:
HNBR offers high-temperature resistance (-40°C to +150°C), abrasion resistance, dynamic fatigue resistance, and cost-effectiveness.
FKM withstands even higher temperatures (-20°C to +200°C) and aggressive chemicals, making it suitable for turbochargers and high-speed electric motors.
