In mold making and product replication, common pain points include mold deformation, easy breakage during demolding, and low replication precision. This is especially true for large products like urban sculptures and car models, or hard casting materials such as gypsum and cement, which demand extremely high precision and durability from molds. One condensation-cure mold silicone stands out with its core advantages: an ultra-low linear shrinkage of ≤0.3% combined with high tear strength and high mechanical strength, plus resistance to burning and high temperatures, making it a "durable tool" for replication. It maximizes the number of replications per mold and ensures precise, error-free reproductions.

Its core competitive edge lies in extreme molding precision. Across the entire product line, shrinkage is ≤0.3%, meaning mold dimensions remain virtually unchanged after curing. This eliminates pattern distortion or dimensional deviation caused by shrinkage. Even the fine details of Buddhist bas-reliefs or the precise snap-fits of car models can be perfectly replicated at 1:1, thoroughly solving the shrinkage and deformation issues of traditional mold silicone and ensuring that replicated products are perfectly consistent with the master model.

Mechanical properties further guarantee durability. Tear strength progressively ranges from 5 KN/m up to 23 KN/m, tensile strength reaches up to 3.98 MPa, and elongation at break is at least 300%. After curing, the mold resists tearing and breaking under tension, withstands the pressure of casting gypsum and cement, and endures repeated friction during demolding of PU and resin materials. The number of replications far exceeds that of ordinary silicone molds, significantly reducing the repetitive cost of mold making. Additionally, the cured mold is resistant to burning, high temperatures, corrosion, and solvents. Whether used for urban sculpture molds outdoors or process molds exposed to various resin solvents, it maintains stable performance without corroding or softening.

Low viscosity and high flowability also make production easier. The base model has a viscosity of only 8,000–10,000 cps. The rubber flows naturally into the mold frame, easily filling every detail of the master model without gaps or dead corners. From small molds for clay concept models, toys, and gifts, to large molds for urban sculptures, car models, and home appliance parts, and even everyday applications like gypsum cement products and soap molds, this silicone precisely adapts. With the advantages of precise replication and superior durability, it becomes the preferred choice for a wide range of mold-making applications.
