High-Performance Liquid Silicone Rubber (LSR) for Precision Mold Making

Welcome to our product page featuring high-performance Liquid Silicone Rubber (LSR) specifically developed for professional Mold Making applications. Our platinum-catalyzed (addition cure) LSR systems are the ideal choice for creating durable, flexible, and highly accurate molds capable of reproducing intricate details from original models. Whether for rapid prototyping, industrial part casting, artistic reproduction, or creating functional components, our mold making LSR provides reliable performance, exceptional mold life, and compatibility with a wide range of casting materials.

Why Choose Our Mold Making LSR?

Our LSR formulations are specifically optimized to meet the demanding requirements of high-quality mold making processes:

• Exceptional Detail Reproduction: The low viscosity of our LSR allows the material to flow easily and fill every part of the mold cavity, capturing even the finest surface textures and complex geometries of the original model with outstanding accuracy.

• High Tear Strength & Outstanding Durability: Our materials are engineered to withstand the physical stresses encountered during repeated demolding cycles, especially when casting parts with undercuts. This high tear strength contributes significantly to a longer mold life, reducing the need for frequent mold replacement.

• Excellent Flexibility & High Elongation: The inherent flexibility and high elongation at break of the cured silicone facilitate easy and safe demolding of cast parts, particularly those with complex shapes or significant undercuts, without damaging either the mold or the finished piece.

• Superb Dimensional Stability: Utilizing a platinum-catalyzed cure system ensures extremely low shrinkage upon curing. This results in molds that precisely maintain the dimensions of the original model, ensuring accuracy in your cast parts.

• Fast and Reliable Curing: Our systems offer predictable and controllable cure times, allowing for efficient production workflows. They can cure at room temperature or be accelerated with heat for faster turnaround.

• Wide Compatibility with Casting Materials: Molds made from our LSR are compatible with a broad spectrum of casting materials, including various polyurethanes, epoxy resins, polyester resins, waxes, plaster, concrete, and more.

• Long-Lasting Mold Life: Experience consistent and reliable performance over a large number of production cycles, providing excellent value.
