Product Features & Advantages
Superior refractive index ensures jewelry surfaces stay clear, no fogging or fading—our core advantage over competitors. Ultra-high transparency allows real-time observation of molding details, improving precision. Excellent tear strength and thermal stability, with strong anti-yellowing and heat aging performance, extending mold service life. High-temperature resistance prevents mold damage during high-heat injection processes. FDA-certified food grade, non-toxic and odorless, safe for dental and close-contact applications. Stable fluidity fits automatic injection molding, supporting mass production and reducing labor costs. Consistent performance ensures uniform molding, lowering defective rates.
How to Use the Product
Step 1: Prepare the injection molding machine, ensure the feeding system is clean and dry.
Step 2: Mix Part A and Part B at 1:1 weight ratio, stir evenly for 2-3 minutes.
Step 3: Pour the mixed LSR into the machine’s feeding hopper.
Step 4: Set optimal parameters (temperature: 150-180℃, pressure: 50-80bar) for injection molding.
Step 5: Allow automatic curing and demold gently, inspecting for precision and surface smoothness before mass production.
