Product Overview 

Industrial Liquid Silicone Rubber (LSR) 6150 series is a two-component (A/B) silicone designed for stable injection molding and consistent mass production. It is widely used for industrial seals, gaskets, O-rings, and waterproof sealing parts, as well as keypads, buttons, protective covers, and consumer electronics components where repeatable dimensions, good rebound, and reliable tear resistance matter. All 6150 grades offer a transparent appearance, supporting clean-looking parts and color customization.

Characteristics

• Two-component LSR A/B, suitable for injection molding

• Transparent across grades; pigmentable for custom colors

• Hardness options: Shore A 30 / 40 / 50 / 55 / 60 / 70

• Stable viscosity selection to match different mold designs and cycle times

• Balanced mechanical performance for durable sealing and touch components

Advantages

• Waterproof sealing reliability: controlled shrinkage helps fit stability in seals and O-rings

• Lower tearing risk: suitable for thin edges and complex keypad structures

• Consistent feel: rebound performance supports keypads/buttons with stable tactile response

• Process stability: viscosity options help improve filling consistency and reduce defects
