Industrial Liquid Silicone Rubber (LSR) is a two-component (A/B) platinum-cured silicone designed for stable injection molding and consistent mass production. It is ideal for silicone bathroom products that require durability, elasticity, and reliable waterproof sealing—especially parts exposed to moisture, frequent handling, repeated squeezing, or pulling.
Bathroom product manufacturers often face practical issues such as thin-edge tearing during demolding, shape change after long-term deformation, and unstable filling that leads to flash or inconsistent feel. 6150-55 is built to reduce these risks through measurable specifications and production-friendly flow. With Shore A 55 hardness, it balances softness and strength, helping products feel comfortable while maintaining structural integrity. Strong tear performance supports designs with thin ribs or small sealing lips, and controlled deformation helps parts keep their original shape after repeated use.
Characteristics
-
Two-part LSR A/B, transparent and pigmentable
-
Stable viscosity for smooth filling and repeatable molding cycles
-
Good rebound for long-term elastic performance
Specific Applications
-
Shower/bathroom sealing parts: gaskets, sealing rings, splash-proof seals
-
Flexible bathroom items: drain stoppers, grips, soft handles
-
Waterproof components: covers, caps, protective sleeves
-
Custom molded silicone bathroom products requiring durability
