LSR 6250-60YH is a two-component, platinum-cured medical grade liquid silicone rubber developed for medical parts that require reliable softness, elasticity, and long-term stability. It is especially suitable for producing vacuum suction bulbs (negative pressure bulbs / bulb syringes) where consistent sealing, repeated squeezing, and clean appearance are important.
Vacuum suction bulb / negative pressure bulb (bulb syringe, suction bulb)
Medical squeezing bulbs, pump bulb components
Medical silicone parts that need stable recovery and durability
Medical-grade positioning with biocompatibility testing support (ISO 10993-oriented projects)
High transparency appearance for clean-looking medical parts
High strength + good resilience for repeated squeezing cycles
Low deformation tendency to help maintain shape and sealing performance
Yellowing resistance & aging resistance for long-term appearance stability
Stable processing window (pot life available for production planning; temperature affects pot life)
Typical values for reference; actual results may vary with process, tooling, and curing conditions.

Comfortable hand-feel + reliable rebound: hardness and resilience support repeated squeezing without “soft collapse.”
Lower risk of edge tearing: higher tear strength helps reduce tearing during demolding, trimming, or assembly.
Stable sealing behavior: low tensile set helps maintain recovery and sealing force over time.
Cleaner appearance: transparency + yellowing resistance reduce cosmetic complaints in long-term storage/use.
Easier quality control: measurable parameters help you set incoming inspection standards (hardness, viscosity, tear strength, tensile set).
Mix A/B components evenly before molding.
Avoid contact with substances containing N / P / S / Sn / Pb, which may affect platinum-catalyzed curing.
Store in a cool, dry place away from direct sunlight; follow shelf-life guidance for best performance.
