Liquid mold silicone rubber is a type of silicone rubber composed of two components, A and B. It is liquid in its natural state and forms an elastic mold after mixing and curing. It is widely used in mold making, electronic component encapsulation, and other fields.

Below is a detailed introduction: 

Basic Characteristics Composition: Typically consists of Component A, a white viscous liquid, and Component B, a transparent curing agent, usually mixed in a 1:1 ratio. 

Hardness: Cured hardness ranges from 22-50A°. Large products or segmented molds generally use high-hardness silicone, while complex patterns and fine, delicate molds are better suited for soft silicone. 

Curing Time: Can be controlled by adjusting the ratio of the curing agent, generally ranging from 10 minutes to several hours. For example, with a 1% addition of curing agent, demolding can be achieved in 6-8 hours.

Physical Properties: Excellent transparency, tear resistance, resilience, and anti-yellowing properties. The product has high transparency, allowing clear visibility of defects such as bubbles in the casting material inside the mold.
